Amyloidosis: An unusual cause of mesenteric, omental and lymph node calcifications

Abstract

We present a rare case of amyloidosis initially presenting with giant calcified inguinal adenopathy. Further imaging revealed diffuse calcifications within the mesentery and greater omentum. Amyloid deposition may mimic chronic granulomatous disorders and primary or secondary neoplastic conditions. Although definite diagnosis is made on histology, the radiologist should include amyloidosis in the differential diagnosis in the absence of a clinical history of neoplastic disorders or chronic infection, especially if extensive intralesional calcifications are seen. Ultrasound may be useful to target solid noncalcified areas in easily accessible extraabdominal locations.
