Splenic Hydatid Cyst is a very rare presentation with less than 5% of total incidences of Cystic Echinococcosis. It is usually due to spread of cysts from other regions leading to secondaries. Primary isolated splenic hydatid cyst without involvement of any other organs is even rarer. We report an unusual case of a female who presented as Abnormal Uterine Bleeding (AUB) with an incidental finding of Isolated Splenic Hydatid Cyst with absence of involvement of any other organ. Patient underwent laparotomy and total splenectomy was done. This case report targets to report a rare case of incidental finding of isolated unilocular hydatid cyst of spleen and describes its management.
