Introduction: Hydatid cyst mainly involves liver and lung. In the liver, it usually
has a benign behavior, but occasionally it may rupture and produces obstructive
jaundice. Rarely hydatid cyst of the liver ruptures directly into the peritoneal cavity.
Case report: A 25-years-old man with progressive abdominal protrusion was
admitted to our center. He had complaint of vague constant abdominal pain, early
satiety and nausea 3 years prior to admission. Physical exam revealed severe
abdominal distension with mild generalized tenserness and muscle wasting. Lab
findings were normal except for 11% eosinophilia in peripheral blood smear.
Sonography of abdomen revealed multiple hypoechoic cysts in the abdominal cavity.
Abdominal CT scan confirmed sonographic finding and revealed additional cysts in
the liver. High titer antibody against echinococcus granolosus was detected in serum
of the patient. Mebendazole (100 mg/kg of body weght) was prescribed for one
month. Complaint of patient abolished and the size of the cysts reduced obviously in
the follow up visit.
Conclusion: Hydatid cyst of peritoneal cavity is an unusual presentation of hydatid
disease even in endemic areas and it is almost always secondary to rupture of the cyst
in liver. Although complete extraction of cyst is the best treatment for single cyst,
three is no consensus about treatment of multiple cysts especially in peritoneal cavity.
But in most centers, medical therapy is added to surgery to reduse the rate of
recurrence. The patient was a case of hepatic hydatid cyst with spontaneous silent
rupture into the peritoneal cavity but the clinical manifestations (abdominal distention
and muscle wasting) was very similar to cirrhosis. Rupture of hydatid cyst may be
asymptomatic or with mild symptoms.
