A case of multiple intra-abdominal splenosis with computed tomography and magnetic resonance imaging correlative findings

Abstract

H e p a t i c s p l e n o s i s r e f e r s t o h e t e r o t o p i c a u t otransplantation and implantation of splenic tissueresulting from the spillage of cells from the spleen after splenic trauma or splenectomy. The true incidence of splenosis is unknown, because this entity is usually an incidental finding at surgery. Splenic implants are usually multiple, and can be localized anywhere in the peritoneal cavity. Splenic implants in the peritoneal cavity may be confused with renal tumors, abdominal lymphomas and endometriosis. We describe computed tomography (CT) and magnetic resonance imaging (MRI) findings in a rare case of multiple intra-abdominal splenosis located along the hepatic surface and adjacent to the upper pole of the right kidney, mimicking a renal neoplasm.

Laparoscopic gastric band removal complicated by splenosis

“…Scintigraphy with technetium‐99 m radiolabelled heat‐damaged erythrocytes or with indium 111‐labeled platelets, and ferumoxides‐enhanced MRI are other valuable tools for diagnosing splenosis 10, 11. Once splenosis is confirmed, no further workup is necessary unless the patient is symptomatic.…”

What is a reliable CT scan for diagnosing splenosis under emergency conditions?

“…Splenosis can be confused with other intra-abdominal masses. Differential diagnoses of splenosis include endometriosis, peritoneal mesothelioma, renal neoplasms, abdominal lymphomas and peritoneal metastatic implants [1] . Splenosis should be suspected in patients with a history of splenic trauma.…”

Intraperitoneal splenosis: CT and MRI evaluation

“…It is usually the result of traumatic rupture of the spleen or splenectomy, and has been shown to develop in up to 67% of splenic injuries (1,3,4). The average interval reported between trauma and abdominal or pelvic splenosis is 10 years, with a range of 5 months to 32 years (5,6).The average reported time delay in thoracic splenosis is 21 years, with a range of 3-45 years (7).…”
