Pelvic echinococcosis presenting as a mass in the gluteal region: a case report.

Hydatid disease of the skeletal system is a rare entity. We present one such case of pelvic echinococcosis in a 62-year-old male who presented with the chief complaints of pain and swelling in the left gluteal region for the past twelve years. The patient was planned for and underwent en-bloc excision of the lesion. Albendazole was used pre- and post-operatively to reduce parasitic load. At the last follow-up, the patient was disease-free and able to carry out his daily activities without much difficulty. We would conclude that, although uncommon, echinococcosis should always be ruled out, especially when dealing with other indolent pathologies of the hip joint.
