BACKGROUND: Hydatid disease is caused by Echinococcus granulosus, endemic in cattle and sheep-raising regions of the world such as Central Europe, South America, Australia, New Zealand and South Africa. Although hydatid disease is more common in liver and lung, it also affects brain, kidney, spleen and muscle. We present a case of intraabdominal hydatid cyst, diagnosed by fine needle aspiration cytology, producing an indentation of the liver, which is uncommon. CASE: A male patient presented with right side abdominal pain. On ultrasonography an intraabdominal solid mass (right hypochondrial) was revealed, and subsequently FNA was done. Smears were diagnostic of hydatid cyst. CONCLUSION: FNAC is a sensitive and rapid technique in diagnosis of hydatid cysts. The present case is unusual, owing to its presentation as a solid abdominal mass seeding over the liver and mimicking malignancy radiologically.
