Pituitary apoplexy manifesting as massive intracerebral hemorrhage -case report-

Abstract

A 68-year-old man presented with severe conscious disturbance caused by pituitary apoplexy resulting in massive intracerebral hemorrhage (ICH). He had been periodically followed up for asymptomatic pituitary adenoma at another hospital for 8 years. Neuroimaging examination revealed pituitary apoplexy and massive ICH located in the left frontal lobe, and the ICH was directly connected to the intratumoral hemorrhage. The diagnosis was massive ICH from pituitary apoplexy. The patient underwent emergent evacuation of hematoma and removal of the pituitary adenoma via bi-frontal craniotomy. Postoperatively, he continued to exhibit deep consciousness disturbance and died 1 month after the operation. Pituitary apoplexy is usually characterized by intra-tumoral hemorrhage. The treatment strategy for asymptomatic pituitary adenoma is still controversial. This case shows that we should always consider the risk of pituitary apoplexy manifesting as ICH which may cause a fatal outcome.
