Introduction: Primary skeletal muscle hydatidosis is a rare manifestation of cystic hydatid disease. We report a case of muscle hydatidosis of the thigh observed in a pregnant woman.

Methods and Results: Our patient is a 30 years old moroccan woman who has been immigrated to Italy for seven years ago. At the fourth month of her third pregnancy she observed a painful swelling of the right thigh, without any other symptoms; an ultrasonographic scan of the thigh showed a noncalcified cystic mass with little round cystic inside in the posterior muscle compartment (diameter 13 cm). After delivery contrast CT and MRI of right thigh were performed showing that the mass had reached 15 cm in diameter. No additional cysts were found on CT of the thorax, abdomen and pelvis. As hydatidosis was strongly suspected, a specific serology was performed with positive result (IHA 1:320). Treatment with albendazole at 400 mg b.i.d. was immediately started; two months after the ultrasonographic scan showed that the primary cyst was smaller while all but one ``daughter'' cysts became smaller and oval, with increased echogenicity. The specific antibody titer (IHA) was 1:80. Surgical resection to remove the cyst ``in toto'' will be the next step of the treatment.

Conclusion: Skeletal muscle hydatid cysts are generally misdiagnosed as either a pyogenic infection or a malignancy. Hydatid disease should be considered in the differential diagnosis of cystic muscular lesions and specific serology has to be performed because routine diagnostic procedures may not always be helpful. The correct diagnosis at the right time allows a radical cure of the disease
