Summary
Primary meningeal melanomatosis, a rare brain tumor, can cause significant brain atrophy and cognitive decline. Early diagnosis and understanding its progression are crucial for patient outcomes.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Primary meningeal melanomatosis is a rare leptomeningeal tumor.
- Diagnosis is challenging due to nonspecific clinical and radiologic findings.
Observation:
- A 21-year-old man presented with seizures and memory impairment.
- MRI revealed brain atrophy and extensive meningeal enhancement.
- Microscopic examination showed pigment invasion into the Virchow-Robin space and cortex.
Findings:
- Immunohistochemistry confirmed cells positive for HMB45 and S-100.
- Pathology confirmed diffuse meningeal melanomatosis.
- The patient experienced disease progression with brain atrophy, seizures, and declining cortical function.
Implications:
- Brain atrophy in meningeal melanomatosis correlates with progressive decline in higher cortical function.
- This case highlights the association between tumor progression and neurological deficits.
