Primary synovial chondromatosis is a rare benign condition of uncertain etiology manifested by synovial proliferation. In the radiology literature, there is only 1 prior case report of primary synovial chondromatosis involving the subtalar joint with only partial description of the imaging appearance. We present a 28-year-old female with primary synovial chondromatosis of the subtalar joint and conduct a literature review of the imaging features of primary synovial chondromatosis presenting in the feet.
