Patient Data
Age: 25 years
Gender: Male
From the case:
Acute subdural hematoma
CT
CT brain
Axial non-contrast
An 11 mm left frontal subdural hematoma effaces the cortical sulci and results in 2 mm of subfalcine herniation. A smaller subdural hematoma in the left anterior temporal fossa measures 7 mm.
Right temporal lobe hemorrhagic contusion is associated with sulcal subarachnoid blood and a thin (2 mm) subdural hematoma.
No intraventricular blood. No transtentorial or tonsillar herniation. Grey white matter differentiation is preserved, with no evidence of acute ischemia.
Case Discussion
In young patients acute subdural hematomas are usually seen in the setting of significant head trauma, usually with associated hemorrhagic contusions.
