Bilateral subdural hematoma

Case contributed by Dr Abiola Ayodele


Altered sensorium following traumatic brain injury.

Patient Data

Age: 40 years
Gender: Male

There are crescentic subdural collections along the convexity of bilateral frontal, temporal and parietal bones which appear hyperintense on T1, T2 and FLAIR sequences consistent with bilateral late subacute subdural hematoma. The collections demonstrate fluid-fluid levels anteriorly. There is mass effect evidenced by effacement of the sulci and gyri. No midline shift. The ventricles are within normal limits.

Case Discussion

Subdural hematoma is a collection of blood in the potential space between the dura and arachnoid mater of the meninges of the brain. It occurs in all age groups, most frequently due to trauma.

MRI findings are in keeping with bilateral late subacute subdural hematoma following traumatic brain injury. The MRI was performed 10 days post injury.
