Abstract:
We report the MR study of a case of high-grade glioma that mimics leptomeningeal carcinomatosis. Superficial gliomas should thus be included in the differential diagnosis of isolated meningeal enhancement.
Insights
High-grade gliomas can mimic leptomeningeal carcinomatosis on MRI. Superficial gliomas should be considered in the differential diagnosis for isolated meningeal enhancement.
Area of Science:
- Neuroimaging
- Neuroradiology
- Oncology
Background:
- Leptomeningeal carcinomatosis presents as diffuse leptomeningeal enhancement on MRI.
- Differential diagnosis is crucial for appropriate patient management.
Observation:
- A case of high-grade glioma demonstrated imaging findings that mimicked leptomeningeal carcinomatosis.
- The glioma exhibited superficial enhancement patterns within the meninges.
Findings:
- Magnetic resonance (MR) imaging revealed a high-grade glioma with atypical meningeal enhancement.
- The imaging characteristics were indistinguishable from leptomeningeal carcinomatosis in this instance.
Implications:
- Superficial gliomas represent an important consideration in the differential diagnosis of isolated meningeal enhancement.
- Neuroimaging interpretation requires awareness of uncommon glioma presentations to avoid misdiagnosis.
