Primary hydatid cyst as a cause of pseudotumor of the buttock

Abstract

Primary muscle hydatidosis is very rare, accounting for less than 1% of hydatid cyst locations, and the gluteus muscle location is exceptional. The objective of this study is to report an exceptional location of hydatid cyst of the gluteus muscle presented like a tumor in the buttock region. Magnetic resonance imaging (MRI) is helpful in diagnosis, it represents the best test for hydatid cysts of the soft parts. It is important to establish the diagnosis preoperatively in order to limit the risk of anaphylactic shock or dissemination in the event of puncture or accidental opening of the cyst during resection. The eradication of this disease is based on prophylaxis.
