Introduction: Splenosis is defined as the heterotopic autoimplantation of splenic tissue following trauma to or surgery on the spleen.

Clinical Case: We present a case of an asymptomatic 73-year-old male in whom hypervascular lesions were detected during routine exams. The patient reported a history of carotid artery surgery and cholecystectomy; he had a laparotomy incision from childhood but was unaware of the reason for it. The patient exhibited slightly elevated carcinoembryonic antigen (CEA) levels. Histopathology revealed intrahepatic heterotopic splenic parenchyma, with no evidence of neoplasia in either of the two lesions, the diameters of which were 1.5 cm and 3.6 cm. Patient received outpatient follow-up care for 24 months and experienced no complications.

Discussion: Our clinical, laboratory, and imaging exams failed to reveal the etiology of the lesion. Because the masses were hypervascular lesions, a percutaneous liver biopsy was not feasible.

Conclusion: Through this report, we emphasize the importance of considering intrahepatic splenosis as a remote possibility in patients with hepatic nodules who have a history of splenectomy.
