Pathological conditions affecting these structures can also be identified. The purpose of this paper was to determine the ability of magnetic resonance imaging to help in the evaluation of tarsal tunnel syndrome. Thirty-three patients with 40 feet were used for this study. All patients presented with complaints of pain along the course of the posterior tibial nerve or its branches and a positive Tinel's sign. Nerve conduction studies were obtained on 29 feet. All feet were evaluated with a magnetic resonance imaging study of the tarsal tunnel. Twenty-one feet eventually required surgery. Magnetic resonance imaging revealed an inflammatory or mass lesion in the tarsal tunnel in the majority of cases. The magnetic resonance imaging findings were confirmed at surgery in 19 patients. The information provided by magnetic resonance imagi...

Apres une chute de velo, il developpe des signes neurologiques, avec troubles de la marche, en rapport avec un granulome du corps de la 5eme vertebre thoracique.

Treatment includes continuous or on-demand clotting factor replacement and radionuclide or open synovectomy. The radiographic findings of hemophilic arthropathy depend on the stage of disease, the age of the patient at onset, and the joint involved. These findings include joint effusion, soft tissue swelling, epiphyseal overgrowth, subchondral cysts, osseous erosion, and secondary degenerative changes. Magnetic resonance imaging (MRI) is the most accurate imaging modality for assessing hemophilic arthropathy and may have a significant impact on patient management. MRI is anticipated to be useful in documenting early joint changes when treatment may be most effective. Hemophilic pseudotumor is a chronic, encapsulated, hemorrhagic fluid collection that usually destroys bone and may become quite large. Both computed tomography and MRI are useful in determining the extent of this lesion.
