Pheochromocytoma presenting as a skull metastasis with massive extracranial and intracranial extension

Abstract

A case of metastatic pheochromocytoma is reported in which the diagnosis was determined on the basis of a painless scalp mass. Subsequent to biopsy and histological diagnosis, further investigations revealed a large skull lesion with intracranial extension, an adrenal mass, and various catecholamine abnormalities. The radiological characteristics and operative findings of this case are described, and the literature regarding pheochromocytoma with intracranial metastatic extension is reviewed.
