An unusual cause of subarachnoid haemorrhage in a patient with newly diagnosed neurofibromatosis: a case report
Tóm tắt
In this report we discuss an unusual cause of subarachnoid haemorrhage in association with neurofibromatosis. A previously fit 55-year-old man developed sudden onset headache with loss of consciousness. He was comatose on admission with no focal neurological signs. Numerous neurofibromas and café-au-lait patches were noted, indicating neurofibromatosis type 1 which had not been previously diagnosed. Computer Tomography brain revealed a grade IV subarachnoid haemorrhage in association with numerous vascular lesions on cerebral angiography. A rare cause of subarachnoid haemorrhages was identified and is discussed in detail.
