Soft tissue coccidioidomycosis on MRI

To determine the appearance of soft tissue coccidioidomycosis on MRI. Two cases of soft coccidioidomycosis with preoperative MR imaging are presented. Prospectively, infection was considered unlikely both clinically and on imaging studies. In retrospect, the MR appearance was nonspecific in one case and suggestive of infection in the other. Radiologists should be prepared to entertain coccidioidal abscess as a differential consideration when soft tissue masses are seen on MRI, even when infection is not suggested clinically.
