Imaging appearance of the involved mesenteric node in patient with systemic amyloidosis: A case report

Amyloidosis is a rare disease characterised by abnormal amyloid protein deposition within the affected tissue. About 37% of the patients were presented with systemic amyloidosis, of which hilar, mediastinal, and para-aortic lymph nodes were involved. Deposition of amyloid protein in the mesenteric lymph node is rarely documented, but when reported, it is seen in isolated or secondary amyloidosis. Despite an indistinguishable imaging appearance of the amyloid- deposit mesenteric node from malignancy, infection, and an inflammation process, the radiologists should be aware of variable imaging findings to be suspicious of amyloidosis. We reported a rare case of systemic amyloidosis with mesenteric node involvement, manifested as node enlargement.
