Findings and diagnosis

Findings

• There is a left subdural hemorrhage of a mixed density extending into the interhemispheric region layering over the cerebral cortex without a significant midline shift or mass effect on the underlying cerebral parenchyma.
• No demonstrable acute focal parenchymal hemorrhage could be seen on the current CT.
• There is soft-tissue attenuation in the retro cerebellar cisterns of uncertain significance at the time of reporting. MRI examination of the brain is required for further evaluation of this finding.

Differential diagnosis

Other fluid material may collect within the layers of the meninges to give the appearance of a subdural hematoma. Conducting a careful history and assessment of radiological findings are essential to rule out purulent accumulation in a subdural abscess. In some cases, the subarachnoid space occupied by cerebrospinal fluid (CSF) with normally reduced brain mass (as in leaky hydrocephalus) may give the appearance of a subdural hematoma.
