title: Cerebral aneurysms and the 'missed' hemorrhage.
abstract: Eleven patients are described in whom a warning subarachnoid hemorrhage, preceding severe or fatal rupture of an intracranial aneurysm, was misdiagnosed; a 12th had a successful outcome from surgery after a single hemorrhage. Erroneous labels included meningitis, migraine, hysteria, tension, and head and neck injury. The vital importance of diagnosing an aneurysm before a major rupture occurs is emphasised. Apart from the 'warning leak', other signs may be due to the location or expansion of an aneurysm, which should alert doctors to the diagnosis.
