A case of post-traumatic retroclival subdural haematoma.

Post-traumatic haematomas in the posterior fossa are uncommon, with a reported incidence of 3%, and occur along the cerebellar convexity [1]. Retroclival location is uncommon and retroclival haematomas are mostly epidural. Only 6 cases of post-traumatic retroclival subdural haematomas (RCSDH) are reported in literature [2]. These are associated with significant trauma and occur in the young. Four cases of spontaneous RCSDH have also been described, three patients with coagulation disorders and one patient with pituitary apoplexy [2]. All six of the reported post traumatic RCSDH were patients aged below 20 years while the non-traumatic RCSDH were older patients. Out of the six post traumatic RCSDH, five have been managed conservatively while one required surgery due to emergence of neurological symptoms. Due to their strategic location and rarity, retroclival haematomas pose a challenge in diagnosis and management [3].
