Patient Data

Bilateral acute on chronic cerebral convexity subdural hematomas. Right anterior parafalcine hypodense subdural hematoma. Mass effect causes effacement of underlying sulci and rightward midline shift at the level of the septum pellucidum. No tonsillar or transtentorial herniation is seen at time of scanning.

Grey-white matter differentiation is preserved. Ill-defined white matter hypoattenuation within the right frontal lobe likely relates to previous ischemia. No hydrocephalus.
