Erdheim-Chester disease, a rare histiocytosis, can present with brainstem lesions mimicking tumors. This case highlights the importance of considering Erdheim-Chester disease in patients with seizures and specific systemic findings.

Area of Science:

  • Neurology
  • Histiocytosis
  • Rare Diseases

Background:

  • Erdheim-Chester disease is a rare non-Langerhans cell histiocytosis affecting multiple organs.
  • Cerebral involvement in Erdheim-Chester disease is uncommon, often presenting as dural thickening or white matter lesions.

Observation:

  • A 26-year-old male presented with a first partial complex epileptic seizure.
  • Brain MRI revealed an asymptomatic pseudo-tumor lesion in the brainstem.
  • Systemic findings included diabetes insipidus, hypophyseal gonadotropic deficiency, and osteosclerosis of long bones.

Findings:

  • The diagnosis of Erdheim-Chester disease was confirmed via tibial biopsy.
  • Brain MRI showed persistent enhancement of the brainstem lesion with Gd-DTPA.
  • Literature review identified 64 cases of Erdheim-Chester disease, with only 7 involving cerebral "tumor"-like lesions.

Implications:

  • This case expands the spectrum of neuroimaging findings in Erdheim-Chester disease.
  • Highlights the diagnostic challenge of Erdheim-Chester disease, especially with atypical presentations.
  • Emphasizes the need for a comprehensive evaluation in patients with unexplained systemic and neurological symptoms.
