Abstract

Hepatic hydatid cysts are usually asymptomatic. Nevertheless, they may rupture, causing anaphylactic shock or fistulation. Cutaneous fistulae caused by ruptured hepatic hydatid cysts are extremely rare. Herein, we report a case of infected cutaneous fistula caused by a ruptured hepatic hydatid cyst. A 57-year-old man presented to Al-Ain Hospital complaining of swelling in his right upper quadrant (RUQ) of 5 months' duration. The abdomen was soft, having a fluctuant tender swelling of 12 cm × 15 cm in the RUQ associated with a pus discharging fistula. The patient was admitted with a provisional diagnosis of abdominal wall abscess with pending sepsis. Surgical incision and drainage were performed under general anesthesia. Initially, around 15 ml of pus was drained, followed by the removal of multiple sized transparent cysts typical of hydatid disease. Postoperative abdominal computed tomography (CT) scan showed multiloculated hepatic cysts in the sixth, seventh, and left lobes with the involvement of the abdominal wall. The patient was treated with oral albendazole 400 mg twice daily for 30 days. Repeated CT scan at 4-month follow-up showed a significant reduction of size of the cysts, indicating proper response to treatment. A cutaneous fistula as a complication of a ruptured hepatic hydatid cyst is extremely rare. Awareness of this complication, especially in endemic areas, and using proper imaging and serological tests are vital for reaching a proper diagnosis.
