title: Primary perisplenic hydatid cyst.
abstract: Splenic parasitic cysts due to flat worm Echinococci resulting in hydatid disease are a rare presentation as primary site even in the endemic regions. Primary splenic parasitic cysts have an incidence of 0.5-4%. A 21-year-old male with pet dogs at home, presented with 3 months history of gradually increasing discomfort in the left hypochondrium and tender splenomegaly. He had marked eosinophilia with normal liver function tests and positive serum IgM Echinococcus antibodies. Ultrasonography showed a cyst in the hilar region of spleen having septations with internal echos. An upper midline laparotomy was performed and a perisplenic cyst was removed along with spleen from the sub-diaphragmatic location. Histopathological examination confirmed acellular fibrous wall of hydatid cyst with germinal layer and scolices in the centre. Postoperatively, patient was continued on oral Albendazole for one month.
