RESUMO
Recurrence of hydatid cyst is one of the important complications of primary hydatid surgery. Here we present a very rare case of recurrent hydatid cyst inside an incisional hernial sac. A 50-year old male operated on for hydatid disease of the liver twice in 1998 and 2001 was admitted to our hospital for an abdominal mass formed under the old median incisional scar. On physical examination, a painless mass of 15 cm in diameter, stretched, hard and well bordered was palpated. There was also a fascial defect inferior to the mass. A herniated hydatid cyst was imaged with both of ultrasonography (US) and abdominal computed tomography (CT). As a surgical treatment hydatid cyst was excised totally together with primary repair of the fascial defect. The patient received preoperative Albendazole therapy, administered at a dose of 10 mg/kg body weight per day from 3 weeks before surgery to 6 months postoperatively. He had no problems in the 1-year follow up (Fig. 2, Ref. 19).
