Summary

Diagnosing neurosarcoidosis can be challenging without systemic signs. This case highlights key diagnostic markers and successful corticosteroid treatment for cerebral sarcoidosis presenting without extracerebral disease.

Area of Science:

  • Neurology
  • Immunology
  • Radiology

Background:

  • Neurosarcoidosis is a neurological complication of systemic sarcoidosis.
  • Diagnosis is challenging when extracerebral manifestations are absent.

Observation:

  • A 42-year-old woman presented with tetraparesis, diabetes insipidus, diencephalic hyperphagia, personality changes, and memory loss.
  • No evidence of systemic sarcoidosis was found.

Findings:

  • Cerebrospinal fluid (CSF) analysis revealed lymphocytic pleocytosis, intrathecal IgG production, and elevated lysozyme.
  • Magnetic resonance imaging (MRI) showed contrast-enhancing granulomas at the brain base, diencephalon, mesencephalon, and spinal cord.

Implications:

  • This case underscores the importance of considering neurosarcoidosis even without systemic involvement.

  • Corticosteroid therapy effectively managed the patient's neurological symptoms.
  • Integrated diagnostic approaches using CSF analysis and advanced neuroimaging are crucial for accurate neurosarcoidosis diagnosis.
