Waldenstrom's macroglobulinaemia and amyloidosis with subcutaneous calcification and lymphographic appearances

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.

Case report: hepatic and splenic calcification due to amyloid

A case of marked hepatic and splenic calcification due to primary amyloidosis is presented. Although the patient had been treated with continuous ambulatory peritoneal dialysis, there was no evidence of a causal relationship with the calcification. Amyloid is known to have an affinity for calcium, but this radiographic manifestation has not been previously reported.
