Tarsal Tunnel Syndrome Secondary to Recurred Schwannoma Arising from the Posterior Tibial Nerve / 대한족부족관절학회지

ABSTRACT

Tarsal tunnel syndrome is defined as a compressive neuropathy of the posterior tibial nerve in the tarsal canal. Schwannoma is a benign tumor that arises from the peripheral nerve sheath. It presents as a discrete, often tender, and palpable nodule associated with neurogenic pain or paresthesia when compressed or traumatized. The growth rate is usually slow, and these lesions seldom exceed 2 cm in diameter. In addition, local recurrence occurs less than 5%. We report on a case of tarsal tunnel syndrome caused by a large recurred space-occupying lesion measuring 4.3x2.7x2.7 cm3.
