Cauda Equina Compression in the Absence of Neurologic Signs.

The patient was a 45-year-old man with a 4-year history of chronic low back pain, intensifying insidiously over the previous 8 months. On physical examination, generalized, severe low back pain was increased with all motions, with no abnormal neurologic signs. The initial physical therapy diagnosis was nonspecific low back pain; however, when the patient reported worsening symptoms at 2-week follow-up, he was advised to complete his previously scheduled magnetic resonance imaging and physician follow-up before further physical therapy. Magnetic resonance imaging revealed a mass at L5 consistent with benign nerve sheath tumor. J Orthop Sports Phys Ther 2016;46(4):312. doi:10.2519/jospt.2016.0405
