HETEROTOPIC OSSIFICATION IN MOYAMOYA-DISEASE - A CASE-REPORT

Moyamoya disease is a rare disorder of cerebrovascular circulation. A review of the literature failed to reveal the association of heterotop ic ossification in patients with this disease; such a case is now pres ented. The patient described had atraumatic intracranial hemorrhage, w as in a coma for a period of time, underwent ventriculostomy and shunt placement, and was left with residual spastic hemiparesis. Evidence o f heterotopic ossification around the hemiparetic shoulder and hip was subsequently noted on radiographic studies and was managed conservati vely. Heterotopic ossification may be a rare complication of the neuro logical deficits associated with moyamoya disease and needs careful co nsideration when joint stiffness persists, despite usual conservative measures.
