Isodense subdural hematoma presenting with paraparesis: case report.

Computerized tomography (CT) has replaced cerebral angiography in many institutions as the diagnostic test of choice in cranial trauma. However, isodense subdural hematomas can be a source of false-negative results on CT scans, resulting in omissions in therapy. The authors report a patient with bilateral isodense subdural hematomas who presented with paraparesis but was otherwise alert and fully oriented. The CT findings caused an initial diagnostic dilemma before being resolved.
