This subject reviewed context a patient who underwent multiple invasive noninvasive examinations to achieve this diagnosis. Both upper lower all degrees has been shown occur amyloidosis. It appears that diffuse involvement tract more common than specific lesion. Our was ultimately found have waxy amyloid plaques extremely friable jejunal mucosa at endoscopy. Radiographically, amyloidosis may cause thickening mucosal folds, finding carries broad differential Arteriography, although not used modality reveal luminal irregularities, truncation, attenuation vasculature. The treatment thus far unrewarding difficult. Several new therapeutic measures which appear promising are discussed.
