The most common site of the disease is the liver, lungs, kidney, bones, and brain. Splenic hydatid disease has been reported to constitute 2% to 6% of patients with abdominal hydatid disease. Because of the rarity of splenic hydatid disease, the probable concomitance of the liver and splenic hydatid cysts should be taken into consideration by clinicians, especially in nonendemic areas. In this report, we present two patients with concomitant splenic and liver hydatid cysts that underwent splenectomy and cystostomy-capitonage. https://acta.tums.ac.ir/index.php/acta/article/view/4932 https://acta.tums.ac.ir/index.php/acta/article/download/4932/4305
