A 43-year-old man with a history of radiculomyelopathy developed recurrent intracerebral haemorrhage confirmed by CT brain scan. Cerebral angiography and systemic investigations showed no underlying cause for the haemorrhage. Cerebral biopsy at the time of evacuation of a haematoma revealed granulomatous angiitis. This condition may be responsive to steroids and should be considered in cases of intracerebral haemorrhage of obscure origin.
