Peripheral neuropathy can be the first sign of cholesterol emboli syndrome (CES). This condition involves nerve damage due to cholesterol crystals, often mimicking other diseases.

Area of Science:

  • Neurology
  • Pathology
  • Vascular Medicine

Background:

  • Cholesterol emboli syndrome (CES) is a rare condition often associated with invasive vascular procedures or atherosclerosis.
  • Peripheral neuropathy is a potential, though less commonly recognized, manifestation of CES.

Observation:

  • A patient presented with peripheral neuropathy as the initial clinical sign of CES.
  • Skeletal muscle and peripheral nerve biopsies showed characteristic cholesterol clefts, necrotizing arteritis, and severe nerve degeneration.
  • Autopsy confirmed extensive peripheral nervous system involvement.

Findings:

  • Peripheral neuropathy can be the primary presentation of CES, likely driven by cholesterol deposition causing arteritis.
  • The neuropathy in CES is characterized by chronic axonal degeneration, potentially due to ischemia of epineurial arteries.

  • Muscle biopsy is crucial for diagnosing CES ante-mortem, while nerve biopsy can reveal epineurial vessel involvement.

    • Implications:

    • CES neuropathy shares features with polyarteritis nodosa, necessitating careful differential diagnosis.
    • CES may be underdiagnosed and should be considered in unexplained neuropathies, especially with a history of vascular procedures or severe atherosclerosis.
