title: Benign Peripheral Nerve Sheath Tumor in a Distance Runner.
abstract: A 31-year-old female runner presented to physical therapy via direct access with an 8-month history of atraumatic left lateral calf pain. Following 1 month of physical therapy, the patient was referred to an orthopaedic sports medicine physician. Ultrasound imaging revealed a 2-cm hypoechoic mass with well-defined margins in the left proximal lateral soleus, while Doppler ultrasound demonstrated increased color flow surrounding the mass. Magnetic resonance imaging findings were consistent with a nerve sheath tumor, and ultrasound-guided tissue biopsy determined the mass to be a benign peripheral nerve sheath tumor.
