[Hemorrhage in the quadrigeminal plate--a case report].

We report a survival patient with hemorrhage in the quadrigeminal plate and discuss the literature of midbrain hemorrhage. A 13-year-old boy developed severe headache and vertigo on April 1st, 1983. On admission, he was comatose and tetraplegic with bilateral facial palsy and total ophthalmoplegia. CT scan revealed a hemorrhage in the midbrain and ambient cistern, but vertebral angiogram no abnormal vessels. Seven hours after admission, continuous ventricular drainage was performed. Disturbance of consciousness, ophthalmoplegia and speech disturbance were gradually improved. CT scan with contrast medium 3 weeks after admission showed a small high density spot in the right quadrigeminal plate. It might be suggested that this spot was the bleeding point and was probably a cryptic microvascular malformation. At the discharge only a minimal limitation of eye ball movement was left.
