Summary
Gliomatosis cerebri, a diffuse brain infiltration, presents nonspecific symptoms, often leading to misdiagnosis. Early consideration and cerebral biopsy are crucial for accurate diagnosis and treatment.
Area of Science:
- Neuropathology
- Neuroimaging
- Oncology
Background:
- Gliomatosis cerebri is a rare, diffuse glial tumor infiltration of the brain.
- Its nonspecific clinical and radiologic features often lead to misdiagnosis as other neurological disorders.
Observation:
- This report details the diagnostic workup for two gliomatosis cerebri cases.
- Case 1: A 64-year-old woman with intracranial hypertension and symmetrical white matter MRI abnormalities.
- Case 2: A 54-year-old man with a prior multiple sclerosis diagnosis presenting with cognitive decline.
Findings:
- Gliomatosis cerebri diagnosis is challenging due to nonspecific presentations.
- Symmetrical white matter involvement on MRI can be a misleading feature.
- Cerebral biopsy is essential for definitive diagnosis.
Implications:
- Highlights the diagnostic challenges of gliomatosis cerebri.
- Emphasizes the importance of considering gliomatosis cerebri in differential diagnoses, even with symmetrical white matter lesions.
- Underscores the critical role of cerebral biopsy in establishing the correct diagnosis and guiding treatment.
