Hydatid cyst is a parasitosis due to the development of the larval form of Echinococcus granulosus which can infest all organs. The pulmonary location comes in 1st position followed by the liver and the spleen. The discovery is generally fortuitous on ultrasound. Hydatid serology guides the diagnosis. Surgical treatment, whether conservative or radical, gives good results. We report the case of a 10-year-old child from Morocco, without any history, who consulted us for a dry cough associated with a medium-sized hemoptysis, a thoracic pain of the right hemithorax and a heaviness of the right hypochondrium revealing a hepatic and splenic hydatid cyst. Although splenic and hepatic hydatidosis remains rare in the pediatric population, this observation serves to emphasize this pathology as well as other differential diagnoses.
