To assess the feasibility, technical success, and effectiveness of high-resolution magnetic resonance (MR)-guided posterior femoral cutaneous nerve (PFCN) blocks. ⋯ Our initial results demonstrate that this technique of selective MR-guided PFCN blocks is feasible and suggest high technical success and effectiveness. Larger studies are needed to confirm our initial results.

The soleus sling has been recently identified as a site of compression of the tibial nerve resulting in tibial neuropathy. Diagnosis of soleal sling syndrome is difficult, and has been based mainly on clinical examination. Advances in MR imaging with high-resolution 3-Tesla scanners have made direct visualization of nerve pathology possible. ⋯ No compression of the tibial nerve at the soleus sling was found in the intraneural ganglion population. We conclude that MR imaging is effective in demonstrating pathologic changes in the tibial nerve at the soleus sling. Based on the MRI findings, we also believe that the soleus sling is a component of the compression when patients present with extraneural ganglion cysts and tibial neuropathy near the knee; in these patients, we recommend release of the soleus sling as part of the definitive management.

To determine the incidence of injuries to the flexor and peroneal retinacula in hindfoot fractures as demonstrated on ankle computed tomography (CT). ⋯ Retinacular injuries are commonly demonstrated on CT in patients with ankle fractures. The contribution of these injuries to fracture outcomes is unknown.

To describe imaging characteristics of neuromuscular choristomas (NMC) and to differentiate them from fibrolipomatous hamartomas (FLH). ⋯ NMC can be confidently differentiated from FLH and malignancies using characteristic imaging and clinical features. When a diagnosis is made, biopsy should be avoided given frequent complication by aggressive fibromatosis.
