Hydatidosis, a zoonotic disease caused by the metacestode of Echinococcus granulosus is considered an economically important disease due to the condemnation of affected visceral organs of domestic animals. The lungs and liver are the most commonly affected organs and is less frequently observed in spleen particularly in buffaloes compared to cattle. Out of 980 slaughtered buffaloes screened for hydatidosis a case of spleenic hydatidosis was noticed. A single cyst projecting from the surface of the spleen was observed. On incision clear watery fluid along with granular structures (protoscolices) escaped out. The inner surface of cyst contained thin, white, translucent membrane studded with cluster of brood capsules. Microscopic examination revealed germinal layer with protoscolices along with eosinophilic laminated layer. There was fibrous connective tissue proliferation around the laminated layer and a mild depletion of the lymphoid cells in the surrounding white follicles.
