Schwannoma of the Posterior Tibial Nerve.

A 61-year-old woman was referred to physical therapy by a podiatrist who suspected a posterior tibialis degenerative tear. To further examine the irritable posterior tibial nerve, a musculoskeletal ultrasound examination was performed, showing a vascularized focal lesion suggestive of a nerve tumor. The patient was referred back to the referring podiatrist, who ordered magnetic resonance imaging, which confirmed the schwannoma of the posterior tibialis nerve. .
