Development of a cutaneous fistula following hepatic cystic echinococcosis.

Hydatid cyst is an infectious disease characterized by cysts formed primarly within the gastrointestinal tract by echinococci. Hepatic hydatid disease, which is the most common form, remains asymptomatic until complications occur. In this report, we present an 80 years old patient who presented with a hepatic hydatid cyst which fistulized to the abdominal skin into the Emergency Department. Computed tomography of the abdomen showed inactive grade 5 cyst. Drainage without removal of the cyst failed to reveal active disease but the microbiological examination showed Klebsiella pneumonia that was sensitive to ampicillin-sulbactam as the causative agent. The treatment of the cyst with a combination of surgical and medical treatment was the successful treatment of Hepatic Hydatid Disease presenting with a cutaneous fistula.
