Differential diagnosis of soft tissue lesions of the foot can be narrowed with imaging. The cystic nature of ganglia, synovial cysts, and bursitis can be confirmed with MR imaging or sonography. Location and signal characteristics of noncystic lesions can suggest Morton's neuroma, giant cell tumor of tendon sheath, and plantar fibromatosis. Synovial-based lesions of the foot and ankle can be differentiated based on presence or absence of mineralization, lesion density, signal intensity, and enhancement pattern. Knowledge of the incidence of specific neoplasms of the foot and ankle based on patient age aids in providing a limited differential diagnosis.
足部软组织病变的鉴别诊断可通过影像学检查来缩小范围。腱鞘囊肿、滑膜囊肿和滑囊炎的囊性特征可通过磁共振成像（MR）或超声检查来确认。非囊性病变的位置和信号特征可提示莫顿神经瘤、腱鞘巨细胞瘤和足底纤维瘤病。足踝部基于滑膜的病变可根据有无矿化、病变密度、信号强度和强化方式进行鉴别。了解基于患者年龄的足踝部特定肿瘤的发病率有助于提供有限的鉴别诊断。
