Focal bone marrow edema isolated to a single bone is a common finding in the ankle. It is often posttraumatic, related to avulsion fracture or contusion, but other causes such as osteoarthrosis, inflammatory arthritides, and impingement can also produce focal bone marrow edema.one marrow edema secondary to bone impaction or bone contusions is likely the result of trabecular microfractures, edema, hemorrhage, or reaction after stress. This pattern is common after ankle inversion injuries and is often noted in the apposing medial malleolus and talus.
