A case of quadrigeminal hamartoma.
A 35-day-old hydrocephalic infant was found by autopsy to have a small nodular mass protruding into the aqueductal channel. The mass, approximately 2.5 mm in size along the neuroaxis and 1.9 mm in transverse plane, subependymally occupied the roof of the aqueduct. This was thought to be the cause of hydrocephalus in this infant. A review of literature on the subject has not shown any other comparable case.
