Core Tip

Core Tip: Splenic hamartoma (SH) is a rare, benign vascular proliferation that is found incidentally and often misdiagnosed. We present a case of incidentally discovered asymptomatic splenic space-occupying lesion, which was misdiagnosed as a splenic aneurysm. Laparoscopic splenectomy was performed and postoperative pathology revealed the presence of SH. The findings of this case study emphasize that imaging studies are insufficient for the differential diagnosis of SH from other diseases, and laparoscopic splenectomy is a less invasive procedure that is useful for diagnostic purposes as well.
