Minor traumatic retroclival epidural haematoma in an adult

Description

A man aged 64 years was transferred to the emergency department because of a witnessed syncopal event. It occurred after standing up and he hit the back of his head against the ground. On arrival, the result of his neurological examinations was normal. Brain CT revealed a hyperdense mass lesion. It extended from the posterior aspect of the dens to the upper clival region (figure 1). Blood tests, including coagulation, had no abnormal findings. Dynamic MRI, magnetic resonance angiography and digital subtraction angiography revealed no meningeal tumours, aneurysms, traumatic arterial dissections, and visible fractures or dislocations in the skull base or craniocervical region.
