Pigmented villonodular synovitis (PVNS) is rare in the foot; however, it developed in the subtalar joint extending around the ankle of a 24-year-old man. The diagnosis was made by a combination of clinical findings, most notably the aspiration of the synovial fluid. Magnetic resonance imaging was most useful in showing the extent of the soft-tissue mass before surgery. Low-signal intensity of the mass, featured on both T1- and T2-weighted images, was suggestive of PVNS.
色素沉着绒毛结节性滑膜炎（PVNS）在足部较为罕见；然而，一名24岁男性的距下关节出现了该病，并蔓延至踝关节周围。诊断是通过综合临床检查结果做出的，最显著的是对滑液进行抽吸检查。磁共振成像在术前显示软组织肿块的范围方面最为有用。该肿块在T1加权像和T2加权像上均表现为低信号强度，提示为色素沉着绒毛结节性滑膜炎。
