SYMPTOMS: The patient presented with right ankle pain and instability. After physical examination, plain x-rays were performed which provided no definite pathology. The patient was referred for a high resolution 3T MRI of the ankle at Siker Imaging. The study was performed with the aid of a specialty 8 channel foot and ankle “ski-boot” coil. Extremely high resolution images were obtained. Dr. Don Resnick of UCSD interpreted the study and was able to make a definitive diagnosis aiding in the subsequent treatment and recovery of the patient. Representative images with pathology clearly labeled and annotated are presented below.


1. Lateral talar dome osteochondral defect.

2. Peroneus brevis and peroneus longus tenosynovitis.

3. Osseous bodies within the ankle joint and sinus tarsi.
