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.
