Myositis due to cholesterol emboli

R J Robinson1, M Pemberton, M J Goddard

  • 1Peterborough District Hospital, Cambridgeshire, UK.

Postgraduate Medical Journal
|December 1, 1993

Summary

Cholesterol emboli can cause myositis, a rare muscle inflammation. This case highlights painful weak legs as a symptom, confirmed by muscle biopsy in a patient with spontaneous cholesterol embolization.

Area of Science:

  • Rheumatology
  • Neurology
  • Pathology

Background:

  • Spontaneous cholesterol embolization is a rare condition.
  • Myositis, or muscle inflammation, is an uncommon manifestation of cholesterol emboli.
  • Cutaneous abnormalities are often present in patients with cholesterol emboli.

Observation:

  • A patient presented with progressive, painful weakness in the legs.
  • The patient's symptoms suggested a neuromuscular disorder.
  • No cutaneous abnormalities were noted in this specific case.

Findings:

  • Muscle biopsy confirmed the presence of cholesterol crystals within muscle tissue.
  • Histological examination revealed inflammatory infiltrates characteristic of myositis.
  • The findings established a diagnosis of myositis secondary to cholesterol embolization.

Implications:

  • This case expands the known clinical spectrum of cholesterol embolization syndrome.
  • It underscores the importance of considering cholesterol emboli in the differential diagnosis of unexplained myopathy.
  • Early diagnosis through muscle biopsy can guide appropriate management and prevent further embolic events.
