Ileal schwannoma in which blood loss scintigraphy was useful for diagnosis.
An 85-year-old woman was hospitalized with severe melena of unknown origin. Upper gastrointestinal (GI) endoscopy and lower GI endoscopy did not detect the origin and we could not establish any diagnosis. To explore the bleeding site, 99mTc-HSA blood loss scintigraphy was performed and a tumor of the small intestine was suspected. Fluoroscopic examination of the small intestine and abdominal CT scan confirmed an ileal tumor measuring 4x3 cm. The mass was a well-demarcated tumor about 80 cm proximal to Bauhin's valve. Partial resection of the ileum was carried out and the tumor was histologically diagnosed as schwannoma. Thereafter, there has been no recurrence of melena nor metastasis of the tumor. It is thought that blood loss scintigraphy is a useful method for unexplained exacerbation of melena.
