An unusual case of back pain: A large Pheochromocytoma in an 85 year old woman.

Introduction: Low back ache is a common complaint in the elderly and in the absence of red flag symptoms can be easily dismissed as benign. Pheochromocytoma presenting as back pain is unusual and to our knowledge, only two previous cases have been reported in the literature with back pain as the 'only' presenting symptom.

Case Presentation: We illustrate the case of an 85 year-old woman who presented with a 6 month history of back pain due to a very large Pheochromocytoma.
