Splenic implant in the jejunum: Radiographic and pathologic findings

We report a patient in whom barium studies and computed tomography revealed an intramural mass in the jejunum that consisted pathologically of ectopic splenic tissue. Because the patient had a prior splenectomy, the lesion probably represented splenosis rather than an accessory spleen. When intramural lesions are detected on barium studies in patients who have had prior abdominal trauma or splenectomy,^99mTc-tagged, heated-red blood cell scintigraphy may be performed to confirm the diagnosis, thereby eliminating the need for surgery in these patients.
