Subdural haematoma (SDH) is strongly associated with non-accidental head injury (NAHI) in children, and is a more specific marker of NAHI than other patterns of intracranial haemorrhage.1 Other than NAHI, the other main situation where SDH occurs in children is in accidental trauma.2 A few case reports have reported the occurrence of SDH in association with venous sinus thrombosis (VST), mostly in adults. These authors postulate that VST causes increased backpressure in the small cortical veins, and this leads to rupture of blood into the subdural space. This argument has been used in medicolegal cases of NAHI, where it is argued by the defence counsel that SDH could have been a consequence of prior VST. The …
