Primary Hydatid Cyst of the Thigh: Atypical Location and Perioperative Strategies to Minimize Recurrence After Accidental Cyst Rupture.

This study presents a rare case of hydatid cyst (HC) located in the left thigh, an atypical site for this parasitic infection, which typically affects the liver and lungs. A 22-year-old female presented with a gradually increasing swelling in the anterior aspect of her left thigh over a period of six months. The diagnosis of the thigh HC was established through a combination of imaging techniques, including ultrasonography and magnetic resonance imaging (MRI), and serological tests. The patient underwent surgical removal of the cyst. We also highlight a management strategy for perioperative accidental rupture of the cyst to minimize the risk of dissemination and reduce the likelihood of recurrence. This report emphasizes the need for a careful multidisciplinary approach to ensure effective diagnosis and successful management of HC, particularly when they occur in atypical locations.
