Imaging of Tumors in the Ankle and Foot

Common bone and soft tissue tumors in the foot and ankle are described in this article, and x-ray and magnetic resonance imaging characteristics are given. Ultrasound can be used for limited indications only, noting that ultrasound features are nonspecific. Of the bone and soft tissue tumors, approximately 7% occur in the foot and ankle. Soft tissue tumors are more common than bone tumors. Tumors of the foot and ankle are generally benign or nonneoplastic. Patients with suspected malignant lesions should be referred to a specialized bone tumor unit before biopsy.
