[Recurrent subarachnoid haemorrhage due to upper cervical A. V.-angioma associated with metameric naevus flammeus (author's transl)].

The case is presented of a recurrent subarachnoid haemorrhage caused by an angiographically-proven spinal A. V. angioma of glomus type II at the C 1--2 level supplied by both vertebral arteries. The angioma was accompanied by a median naevus flammeus over the occipito-cervical region. The clinical differentiation between subarachnoid haemorrhage of cerebral and spinal origin is discussed and emphasis is placed on the significance of complete cerebral angiography for the detection of the sources of recurrent subarachnoid haemorrhage of undetermined origin.
