DORSAL MIDBRAIN SYNDROME DUE TO MESENCEPHALIC HEMORRHAGE - CASE-REPORT WITH SERIAL IMAGING

Spontaneous, nontraumatic, nonhypertensive, midbrain hemorrhage is an uncommon cause of the dorsal midbrain syndrome. We describe a patient with this syndrome in whom the initial neuroimaging studies failed to clearly identify the lesion. Subsequent magnetic resonance imaging stu dies disclosed a dorsal midbrain hemorrhage. The patient experienced g radual spontaneous resolution of her dorsal midbrain signs and symptom s over several months. The evolution on serial neuroimaging studies of the dorsal midbrain hemorrhage in this patient is described.
