MR imaging features of tumors of the ankle and foot

MR imaging of neoplasms of the foot and ankle is useful in assessing the extent of lesions and their relationship to anatomic boundaries and vital structures. Certain lesions possess trademark features that are virtually diagnostic, however, usually MR imaging is nonspecific in characterizing soft tissue neoplasms as benign or malignant. Similarly, MR imaging is frequently not diagnostic for bone lesions and plain films are still crucial for their evaluation. MR imaging can be particularly useful in assessing the status of the bone marrow and the extent of the lesion, which are important considerations for surgical treatment and potential limb salvage.
