Background: Cystic echinococcosis (CE) is a parasitic infection that is caused by the tapeworm Echinococcus granulosus. CE is very common, especially in the rural areas of developing countries. The most commonly affected organs by hydatid cysts are the liver and the lungs. However, the primary splenic hydatid cyst (PSHC) is a very rare manifestation of CE with an incidence of 0.5-8%.
Case presentation: A 17-year-old female patient presented with abdominal pain which gradually increased over months, along with anorexia and vomiting. Computerized tomography showed a massive splenic cystic mass. An open total splenectomy was performed. By follow-up, the platelet count and a postoperative chest X-ray were normal. The patient was prescribed Albendazole and analgesics. The pathological study confirmed the diagnosis of PSHC.
Conclusion: Despite the occurrence of PSHC being very rare, it is very important to take it into consideration, especially in endemic areas.
