1 Resident in Diagnostic Roentgenology.
The roentgenologic findings in 24 patients with known gastrointestinal deposition of amyloid are reviewed. The most significant finding was motor dysfunction, manifested by esophageal reflux and weak motor activity, gastric retention, intestinal dilatation or segmental dilatation and contraction, diminished motility, prolonged transit, and, eventually, obstruction. Scleroderma and ischemia of the bowel can also produce these changes, but these diseases often can be differentiated clinically from amyloidosis, and a diagnosis of amyloid can be easily confirmed by biopsy of the involved organ or by rectal biopsy.
