Abdominal visceral calcification in secondary amyloidosis: CT findings

Amyloid fibrils have an affinity for calcium, and radiographically detectable calcified amyloid deposits may occur in both primary and secondary amyloidosis. However, abdominal visceral calcification is rare. A patient with secondary amyloidosis due to juvenile rheumatoid arthritis is described who developed extensive liver, adrenal, and renal calcification shown by computed tomography. Adrenal calcification in amyloidosis has not been previously described.
