Cavernous malformation is an abnormal vascular lesion caused by dysfunction in vessel wall. This disease is often asymptomatic but seizure, hemorrhage, progressive neurological deficit and headache may be seen. Cavernous malformation usually presents as individual lesions. Multiple lesions are rare and can be familial with an autosomal dominant pattern. In this study a 41-year-old woman presenting with progressive neurological deficit consisting of diplopia, vertigo and facial palsy to hospital was examined and multiple cavernous malformation lesions were found. These lesions were also present in examination of other family members.
