A 58-year-old Afro-American male presented with unspecified lower back pain. General physical and abdominal, musculoskeletal, and neurological exam was normal.
Work-up included an MRI of the lumbar spine which identified an incidental mass in the retrorectal space. This mass showed hyperintensity on T2W images. Further imaging with a CT scan confirmed the 7-cm smooth walled mass in the retrorectal space abutting but without any involvement of the surrounding viscera. A complete colonoscopy and a cystoscopy did not reveal any involvement. A transperineal CT-guided biopsy was suggestive of a spindle cell tumor of neural origin based on positivity of S-100 and neuron-specific enolase (NSE) stains.
