Differential Diagnosis for Back Pain and Fecal Incontinence

Single Most Likely Diagnosis

  • Cauda Equina Syndrome: This condition is characterized by compression or damage to the cauda equina (the bundle of spinal nerves and spinal nerve roots), which can cause back pain, fecal incontinence, and other symptoms such as urinary incontinence and numbness in the legs. The combination of back pain and fecal incontinence makes this a highly plausible diagnosis.

Other Likely Diagnoses

  • Spinal Stenosis: Narrowing of the spinal canal can compress the spinal cord or nerves, leading to back pain and, in severe cases, fecal incontinence due to nerve damage.
  • Herniated Disk: A herniated disk in the lower spine can compress nerves, causing back pain and potentially leading to fecal incontinence if the nerves controlling bowel function are affected.
  • Spinal Cord Injury: Trauma to the spine can result in damage to the spinal cord, leading to a range of symptoms including back pain and fecal incontinence, depending on the level and severity of the injury.

Do Not Miss Diagnoses

  • Spinal Epidural Abscess: An infection in the epidural space surrounding the spinal cord can cause back pain, fever, and neurological deficits, including fecal incontinence. This condition is medical emergency requiring prompt diagnosis and treatment.
  • Spinal Tumor: Tumors in the spine, whether benign or malignant, can compress the spinal cord or nerves, leading to back pain and potentially fecal incontinence. Early diagnosis is crucial for effective treatment.
  • Multiple Sclerosis: An autoimmune disease that affects the brain and spinal cord, multiple sclerosis can cause a wide range of neurological symptoms, including back pain and fecal incontinence, due to the demyelination of nerve fibers.

Rare Diagnoses

  • Tabes Dorsalis: A late manifestation of syphilis, tabes dorsalis involves the degeneration of the dorsal columns of the spinal cord, leading to symptoms such as back pain, incontinence, and sensory deficits.
  • Syringomyelia: A condition characterized by the formation of a fluid-filled cavity or syrinx within the spinal cord, syringomyelia can cause back pain, muscle weakness, and loss of reflexes, as well as fecal incontinence in advanced cases.
  • Neurosyphilis: In its various forms, neurosyphilis can affect the spinal cord, leading to back pain and a range of neurological symptoms, including fecal incontinence, depending on the extent and location of the infection.
