Blue rubber bleb nevus syndrome: imaging of small bowel lesions with peroral CT enterography.
Summary of "Blue rubber bleb nevus syndrome: imaging of small bowel lesions with peroral CT enterography."
Blue rubber bleb nevus syndrome (BRBNS) is a rare entity that consists of multiple venous malformations involving several organ systems, particularly the skin and the gastrointestinal tract. The diagnosis is based on clinical findings; however, imaging is required to investigate the extent of involvement and complications. A 17-year-old patient, with multiple blue skin nevus, was admitted to the emergency room of our hospital with severe gastrointestinal bleeding and melena. Upper endoscopy showed two wine-color vascular lesions in the duodenum, and colonoscopy revealed multiple lesions in the colon. Peroral CT enterography demonstrated multiple (more than 30) contrast-enhanced polypoid small bowel lesions, ranging in size from 5 to 16 mm. Some lesions contained millimetric calcifications representing phleboliths. The patient also had three pancreatic lesions which showed homogenous enhancement on the delayed images. Our findings show that peroral CT enterography is useful to demonstrate the extent of small bowel lesions of BRBNS. This is the first report of pancreatic involvement of BRBNS.

Medical and Biotech [MESH] Definitions
Nevus, Blue
Usually a benign tumor, that commonly presents as a solitary blue nodule with spindled MELANOCYTES covered by smooth SKIN. Several variants have been identified, one variant being malignant. The blue color is caused by large, densely packed melanocytes deep in the DERMIS of the nevus. In CHILDREN, they usually occur on the BUTTOCKS and LUMBOSACRAL REGION and are referred to as cellular blue nevi. Malignant blue nevi are more commonly found on the SCALP.
Nevus Of Ota
A macular lesion on the side of the FACE, involving the CONJUNCTIVA and EYELIDS, as well as the adjacent facial skin, SCLERA; OCULOMOTOR MUSCLES; and PERIOSTEUM. Histological features vary from those of a MONGOLIAN SPOT to those of a BLUE NEVUS.
Short Bowel Syndrome
A malabsorption syndrome resulting from extensive operative resection of the SMALL INTESTINE, the absorptive region of the GASTROINTESTINAL TRACT.
Capsule Endoscopy
Non-invasive, endoscopic imaging by use of VIDEO CAPSULE ENDOSCOPES to perform examination of the gastrointestinal tract, especially the small bowel.
Technetium Tc 99m Exametazime
A gamma-emitting radionuclide imaging agent used in the evaluation of regional cerebral blood flow and in non-invasive dynamic biodistribution studies and myocardial imaging. It has also been used to label leukocytes in the investigation of inflammatory bowel diseases.
