A case of jejunal neurofibroma in von Recklinghausen's disease with active hemorrhage, detected and located with gastrointestinal bleeding scintigraphy: A case report with literature review.

A 69 year old patient was admitted to hospital with massive gastrointestinal hemorrhage. The clinical presentation of the patient, except for bleeding, was dominated by the presence of neurofibromatosis type 1 - Von Recklinghausen disease. The patient was referred to multislice computed tomography (CT) angiography, magnetic resonance imaging (MRI), esophagogastroduodenoscopy and colonoscopy, which were performed without successful detection of the bleeding site. The MRI examination showed the existence of a tumor located in the small pelvis. After that, gastrointestinal bleeding scintigraphy (GIBS) with technetium-99m (99mTc) pyrophosphate in vivo labeled erythrocytes was done. Gastrointestinal bleeding scintigraphy showed active intraluminal bleeding from the projection of jejunum, which flowed through the small intestine to the descending colon and the sigmoidal and rectal segment of the colon. Surgical resection of the abdomen revealed the existence of tumors in the jejunum with active bleeding and resection and anastomosis was done. Histopathological verification showed intestinal neurofibroma. In this case GIBS showed usefulness in proving the existence of active bleeding in the small intestine and its localization, and it was of a great help in planning the surgical treatment of a patient.
