钙化性腱膜纤维瘤的影像学特征

目的探讨钙化性腱膜纤维瘤(CAF)的影像学特征。 方法回顾性分析襄阳市中心医院、汕头市中心医院、湖北省肿瘤医院及红河州第一人民医院放射科2005年1月至2022年5月期间经手术病理证实的12例CAF患者临床资料、影像学表现及病理组织学特点，并复习相关文献。 结果12例CAF患者中男性6例，女性6例，年龄2~75岁，其中4例位于手部，3例位于足部，3例位于髋部，1例位于跟腱，1例位于腹腔。临床上多表现为缓慢生长的无痛性肿块。X线平片多显示为非特异性软组织肿块，直径多小于3.0 cm，伴有不同程度的细小点状或结节状钙化，形态不规整，无包膜，很少观察到邻近骨质受累；CT和磁共振成像(MRI)显示病灶多靠近手掌、足部腱膜或腱鞘处，发生于肌腱内则与肌腱纵轴方向一致。 结论CAF的影像学表现具有一定特征性，结合发病部位和年龄，可提高对该病的准确诊断。

Imaging features of calcifying aponeurotic fibroma

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 X-ray images showed non-specific soft tissue masses diameters less than 3.0 cm, 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.
