Death Due to Cerebral Vasospasm.

It is accepted by many that vasospasm occurring as a result of ruptured intracranial aneurysm may contribute to the death of the patient. In the present case, although widespread spasm in the intracranial circulation was demonstrated, no aneurysm could be found either in life or at necropsy. The cause of the spasm is not known but its effects on the brain were undoubtedly responsible for death. The radiological features of the vasospasm are discussed and the pathology of the brain described and compared with that due to reduced cerebral blood flow from other causes.
