At the relevant date, being the instigation of protective measures on 7 May 2022, the child was suffering significant physical harm attributable to the care given to him, not being what it would be reasonable to expect a parent to give him.
1. M was presented to hospital on 1 May 2022 (c. 8 months of age) by which time subsequent investigations established that he was suffering from the following:
(a) Chronic bilateral multifocal subdural collections.
(b) Acute subdural blood over the left frontal lobe.
(c) Parenchymal injury (laceration) to the cortex of the left frontal lobe.
(d) Multiple bilateral cortical vein (bridging veins) thrombosis towards the vertex.
(e) A lesion (infarction) in the splenium of the corpus callosum.
(f) Blood over the surface of the tentorium.
(g) Encephalopathy.
(h) Asymmetric bilateral multiple retinal haemorrhages affecting multiple layers, some with white centres, more extensive in the left eye where all quadrants were affected.
2. The injuries at paragraph 1 (above) resulted from one or more episodes of abusive head trauma.
3. The mother and/or father inflicted the abusive head trauma by a mechanism or
mechanisms that they have not disclosed.
4. If only one parent inflicted the injuries, the other parent failed to protect the child from being injured non-accidentally.
Background leading to the Proceedings.
"...it is absolutely clear, there are haemorrhages present behind both eyes" and he went on to state that it would be "hearing hoofs and thinking unicorns to think of anything else".
The ophthalmology treating team concluded that their findings were consistent with an acceleration and deceleration mechanism akin to shaking the brain, always a pointer to potential NAI. The clinical investigations did not reveal any suspicious bruising or fractures.

"In my opinion, an injury mechanism involving rapid stroke repetitive acceleration - deceleration forces, such as a shaking type injury, is more likely than an impact mechanism to explain this constellation of injuries. The accidental fall from the bed is unlikely to fully explain M's injuries. It is possible that a fall from the bed caused some acute subdural bleeding in the context of established subdural collections caused by an earlier episode of trauma. In my opinion, in the absence of any underlying bleeding or metabolic disorder, M was likely subject to an episode of non-accidental injury. The presence of bilateral haemorrhages raises the suspicion of non-accidental injury."
"Re-bleeds into already established chronic subdural collections are known to occur with minimal force following trivial trauma. It is possible therefore that if M had established subdural collections at the time of the fall from the bed he was predisposed to an acute bleed."
He went on to opine that the radiology was consistent with a single recent episode of trauma:
"I am not able to exclude an earlier episode of trauma that caused chronic subdural collections. The clinical presentation is consistent with a recent episode of trauma shortly before his presentation. The vomiting for several days suggests he might have been subject to an earlier episode of trauma".
"The causes of M's injuries should depend on the causation of his intracranial haemorrhage and brain injuries. A fall as the cause of the retinal haemorrhages cannot be completely ruled out but neither can non-accidental injury be ruled out simply by the presence of retinal haemorrhages".
He deferred to the paediatric, neurosurgical and neuroradiological colleagues [Dr Cleghorn, Mr Jalloh and Dr Hogarth respectively] as to the possible significance of subdural haemorrhages of different age, if such there were. He continued that as far as the timing of the retinal haemorrhages was concerned, they were most likely to have followed the intracranial haemorrhage and a presumed rise in intracranial pressure by a few minutes.
"Arachnoid cysts can also rupture causing cerebrospinal fluid [CSF] to leak into the subdural space causing a subdural hygroma. Again, this is rare and when it occurs it is usually on the same side of the cyst although bilateral hygromas can occur. My impression of subtle expansion of the middle fossa disproportionate to the size of the cyst is supportive of cyst rupture. The growth in the arachnoid cyst suggests that it is accumulating CSF. Arachnoid cysts can grow over time due to trapping of CSF that can flow in but cannot flow out or due to the production of CSF by the cyst membrane. Most arachnoid cysts do not grow but some do."
"As M's arachnoid cyst has grown and is large on the December 2022 MRI, I add more weight to its possible contribution to the subdural collections than placed in my original report. In my opinion it is possible that subdural collections [hygromas] were caused through rupture of the arachnoid cyst following trivial trauma, which then predisposed M to a subdural bleed from the bed fall."
"..unable to explain the small focus of tissue damage in the left frontal lobe cortex or the blood within the posterior fossa or the signal change in the splenium of the corpus callosum seen on the MRI head scan from May 2022 purely on the basis of there being an arachnoid cyst".
Part 25 Experts Meeting – 27th February 2023
"I think it's almost certain that the retinal haemorrhages are secondary to intercranial haemorrhages and therefore, it's not a triad, which is diagnostic, it's a duad, and therefore of course I'm putting the onus on Mr Jalloh and his neuro-radiology colleagues to come up with the reason for the injuries".
"In the context of already having chronic collections, a bed fall, a little bit of acute subdural bleeding was sufficient to push him over the edge to cause his presentation with apnoea... with encephalopathy, and perhaps also therefore with retinal haemorrhages. So for me the bed fall is fairly consistent with the acute subdural blood seen on the scan. So then the question comes down to what is the source of the chronic subdural collections. I must admit only on reviewing the December, the second scans or the later scans in December and looking back at the scans in May I added more weight to the possible importance of the arachnoid cysts [sic]... so I think it is possible that M had an arachnoid cyst that was actually, you know, initially quite large, but ruptured causing subdural hygromas on both sides of the head with a progressively increasing intra cranial pressure over the few days prior to his presentation and that caused the vomiting that he presented with prior to his index presentation. Then the bed fall on the day of presentation pushed him over the edge. So had chronically raised pressure at that point, presenting with encephalopathy, perhaps developed retinal haemorrhages because of that."
"I suppose this possibility of an arachnoid cyst rupturing, none of this excludes the possibility of a non-accidental injury, it's a potential vulnerability in M if he did suffer inflicted injury, but I think it's just possible that he could have had a ruptured arachnoid cyst following trivial trauma, so not necessarily inflicted trauma that resulted in these chronic collections with the then acute event. I think we can't exclude that in this case."
"So I think when I'm listening and trying to interpret these extraneous elements outside the finding of subdural collections, what I'm saying is that I'm offering the possibilities for these different findings and I'm saying where the level of confidence is low, and I'm saying where things are essentially unknown. This is why it's a very difficult case, it's a bit of a grey case because its very difficult to exclude inflicted injury and its very easy to explain lots of areas and elements that are seen on the scan from trauma because trauma can cause lots of different presentation and patterns of injury in the head, so we can't exclude it. But on the other hand, what I can say to the court is the overall picture here is not, what could we call it to use a poker card game term, a "full house" of findings that strongly point to an inflicted injury. We're not in that context in my view which is why I was deliberately very circumspect about offering an executive summary on my report, because there are several elements here where I am leaving question marks hanging over some of the things I've seen on the scans, so I'll leave my comments there".
"So I do still remain somewhat uncomfortable with a short fall producing that diffuse haemorrhage, but ultimately it's an unknown." Then he continued, "I don't think I can say its highly suspicious for anything like inflicted injury, but I just remain somewhat uncomfortable, because this is a difficult case to provide a clear explanation to the court for, in my view".
He went on to say [E456]:
"Now what we can say, and this is largely I think because of Mr Jalloh's comments on the arachnoid cyst, I think we do have to consider very seriously that the arachnoid cyst is responsible for the chronic subdural collections and a short fall would therefore be occurring in an infant who is unusually vulnerable to a low mechanism of trauma. So, we then have some of the other elements which we've discussed, and I think they can all be encompassed potentially from that scenario. I think that's a potential explanation for what I'm seeing on the scans which doesn't leave me with significant discomfort if I consider the possibility that the blood that I was seeing around the tent is actually on the tent rather than the posterior fossa, which I think is possible".
"We can explain the findings on the scans with an inflicted injury but we can also, I think, entertain the explanation offered by the parents as being a plausible cause involving the short fall from the bed for the constellation of findings here. I've managed to find a sharper degree of focus through the discussion this evening and having considered what Mr Jalloh's comments have been as well, that's been extremely influential".
"My preferred explanation for M's clinical presentation is a recent episode of trauma shortly before his presentation that caused apnoea, a possible seizure, and fluctuating conscious level, and an earlier event several days [or longer] prior to his presentation that caused subdural collections, raised intra cranial pressure and vomiting. Possible recent trauma includes the bed fall or an episode of non-accidental injury. Possible causes of the earlier event that caused subdural collections include rupture of the arachnoid cyst from trivial trauma or an episode of non-accidental injury. In my opinion there are no features of M's clinical presentation in hospital or radiology that distinguish these hypotheses."
"Having reflected extensively on this particularly complex case, I am now comfortable in accepting the possibility that the combination of the arachnoid cyst and subdural hygromas could have made M unusually vulnerable to low level mechanism of injury. In such a scenario a short fall as described could account for the unusual array of features seen on the scans. In consideration of the possibility of inflicted injury, I would say that this cannot be entirely excluded on the basis of the neuroradiology evidence but some of the features shown on the scans are not typically seen in the context of a shaking mechanism of injury in my experience brackets [i.e. the spot in the splenium of the corpus callosum and the tiny cortical injury to the left frontal lobe]. This case includes a number of unusual or anomalous features that are not typical of inflicted injury, in my view. On that basis I see no reason from the medical opinion perspective to favour inflicted injury as a cause for the findings over accidental injury but I leave it to the court to decide which explanation it prefers".
"I am comfortable with accepting the short fall from the bed, in the context of there being subdural hygromas and an arachnoid cyst, as an explanation for the findings on scans. I see no particular reason to favour inflicted injury on the basis of what is shown on the scans."
5.5 Regarding the large collections with dark density there are three main differential diagnosis as follows:
5.5.1 long standing subdural haematomas overlying both cerebral hemispheres. Subdural haematoma refers to haemorrhage overlying the brain surface within the upper brain over the arachnoid membrane.
5.5.2 Hygromas overlying both cerebral hemispheres. Hygroma refers to abnormal extravasation / leakage of fluid within the space overlying the cerebral service.
5.5.3 Prominent CSF spaces may represent a normal anatomical variant known as B9 enlargement of subarachnoid space in infancy.
5.6 Differentiation of these conditions on non-enhanced CT is not quite accurate. However these collections will be further evaluated on the follow up MRI.
5.7 In particular, the collection overlaying the temporal lobe / sylvian fissure may represent an arachnoid cyst. However this differential diagnosis is quite less likely because the collection is in continuation with the rest of CFS collection. In addition, there is no "enclosed" membrane around this lesion to support this differential diagnosis. Moreover, the local mass effect from the collection is more diffuse than focal. Therefore presence of arachnoid cyst is quite less likely and most probably the dark density changes overlying left cerebral hemisphere are representing a type of collection.
5.8 There is a relatively small area of grey collection overlying the left frontal lobe (image 3). The appearances are in keeping with subdural haematoma.
5.9 There are a couple of areas linear bright density overlying the right frontal lobe. The appearances are in keeping with cortical vein thrombosis (image 4).
"The appearance most probably represent focal brain laceration."
"In summary there has been most probably haemorrhages of various ages overlying both cerebral hemispheres. A differential diagnosis is hygroma for some of cerebral surface collection. There has also been associated tiny infarction of the splenium of the corpus callosum and cortical vein thrombi. There has also been most probably left frontal lobe small laceration of the brain tissue. Considering the above differential diagnosis is ruled out by related experts in a non-mobile child the appearances are most probably representing severe head trauma including non-accidental head trauma. This does not usually happen during daily activities of life. The most likely mechanism is severe "to and fro" shaking. There has been most probably more than one episode of trauma, [possible one single episode of trauma cannot completely be ruled out].
"There was no evidence of vitreous haemorrhages but there were retinal haemorrhages more in the left eye than the right eye. In the right eye there were diffuse multi layered flame haemorrhages which were too numerous to count and small in size at the posterior pole and beyond the macula arcades. There was bleeding near to the optic nerve superonasally. The left eye had significant and diffuse large posterior polar haemorrhages extending from the macula to the optic disc with associated retinal oedema. The left optic nerve was hyperaemic and swollen".
