A tale about an unusual cause of pygalgia in non‐radiographic axial spondyloarthritis

Abstract

AbstractSchwannoma are tumors of Schwann cells of the peripheral nerve sheath. Sacral location is rarely reported especially in spondyloarthritis patients. Herein, we report a case of uncommon pygalgia in a 25‐year‐old man with history of a non‐radiographic axial spondyloarthritis and in whom the diagnosis of sacral Schwannoma was established.
