Abstract：ObjectiveTo investigate the imaging features of calcifying aponeurotic fibroma (CAF). MethodsBetween January 2005 and May 2022, the clinical data, imaging manifestations, and pathological histological features of 12 patients with CAF confirmed by surgical pathology who were treated in the Radiology Departments of Xiangyang Central Hospital, Shantou Central Hospital, Hubei Cancer Hospital, and the First People′s Hospital of Honghe State were retrospectively analyzed, and the relevant literatures were reviewed. ResultsAmong the 12 patients of CAF, there were 6 males and 6 females, ages ranging from 2 to 75, with 4 cases localized in the hand, 3 in the foot, 3 in the hip, 1 in the tendo calcaneus, and 1 in the stomach. Clinically, they generally manifested as slowly expanding, painless masses. Plain Xray images showed nonspecific soft tissue masses diameters less than 30cm, varying degrees of tiny punctate or nodular calcification, uneven shape, no envelope, and infrequent bone involvement. The lesions were mostly found close to the tendon membrane or tendon sheaths of the palm and foot, and occured within the tendon in the same direction as the longitudinal axis of the tendon, according to magnetic resonance imaging (MRI) and CT scans. ConclusionsSymptoms of CAF imaging have a specific appearance. The accuracy of the disease′s diagnosis can be increased by taking into account the location and age of the patient.
