Peroneus Longus and Peroneus Brevis Tendon Tears: 3T MRI Hindfoot

SYMPTOMS: A patient presented with pain and instability of the ankle. During physical examination it was revealed that the ankle pain was chronic and not healing for more than a year post-trauma. The patient experienced instability, weakness and a decreased range of  motion compared to the opposite ankle. The physician ordered a 3T MRI to include specialty sequences utilizing a dedicated specialty 8-channel ski-boot foot and ankle coil. Extremely high resolution images were obtained which aided the subspecialty  radiologist’s diagnosis of multiple pathologies including “cortical thickening of the calcaneus at Gissanes angle”. Images representative of the study are presented below with pathology clearly labeled and annotated. SUMMARY OF FINDINGS: 1. Hindfoot valgus with midfoot sag with resulting subfibular impingement as evidenced by soft tissue edema inferior to the fibula, cortical thickening of the calcaneus at Gissanes angle, edema within...

Morton’s Neuroma: 3T MRI Forefoot

SYMPTOMS: Patient experienced a chronic pain and aching in the left forefoot. After physical examination, X-rays were obtained. The podiatrist referred the patient for high resolution 3T MRI utilizing a dedicated 8-channel foot and ankle “ski-boot coil”. The specialty imaging coil for the 3T MRI scanner aided in generating much higher resolution MRI images than can be obtained with traditional open architecture or 1.5T equipment. Extremely high resolution images were obtained aiding the radiologist and referring physician in identifying multiple subtle pathologies including a somewhat rare finding of “Morton’s Neuroma”. SUMMARY OF FINDINGS: 1. Enhancing 5 mm soft tissue density between the plantar aspect of the third and fourth metatarsal heads, consistent with a small Morton’s neuroma. 2. Nonspecific synovitis at the third through fifth tarsometatarsal joints and at the third metatarsophalangeal joint. 3. Developing second and third claw...
