Summary

Neurosarcoidosis, a rare neurological manifestation of sarcoidosis, can present without systemic signs, complicating diagnosis. Histological analysis is crucial for confirming this challenging pseudotumoral form, even after decades of isolated neurological symptoms.

Area of Science:

  • Neurology
  • Immunology
  • Pathology

Background:

  • Sarcoidosis is a multisystemic inflammatory disease affecting various organs.
  • The nervous system is involved in 5-15% of sarcoidosis cases, leading to neurosarcoidosis.
  • Neurosarcoidosis presenting without overt systemic disease is uncommon and diagnostically challenging.

Observation:

  • This report details a rare case of pseudotumoral neurosarcoidosis.
  • The patient, aged 61, exhibited isolated neurological signs for 25 years.
  • No concurrent signs of systemic sarcoidosis were evident during this prolonged period.

Findings:

  • The pseudotumoral presentation of neurosarcoidosis can mimic other neurological conditions.
  • Prolonged, isolated neurosarcoidosis without systemic manifestations is possible.

  • Histological examination proved essential for definitive diagnosis in this case.

    • Implications:

    • Highlights the importance of considering neurosarcoidosis in cases of unexplained neurological deficits, even without systemic symptoms.
    • Emphasizes the diagnostic value of histopathology for rare presentations of neurosarcoidosis.
    • Suggests that long-term, isolated neurosarcoidosis may be underdiagnosed.
