Trigeminal nerve lipoma: MR findings
Journal of Computer Assisted Tomography
|May 1, 1987
Summary
Trigeminal nerve lipomas are rare tumors causing progressive neurological symptoms. CT and MR imaging precisely locate these lipomas and characterize tissue before surgery.
Area of Science:
- Neurology
- Radiology
- Oncology
Background:
- Trigeminal nerve lipomas are uncommon neoplasms.
- They often present with focal neurological deficits due to nerve compression.
Observation:
- This study details the computed tomography (CT) and magnetic resonance (MR) imaging characteristics of trigeminal nerve lipomas.
- The intimate relationship between these lipomas and nerve fascicles is highlighted.
Findings:
- MR imaging, particularly T1 and T2 weighted scans, reveals characteristic signal intensities.
- These signal changes are crucial for precise anatomical localization and tissue differentiation.
Implications:
- Accurate pre-surgical characterization using CT and MR imaging is vital.
- Improved understanding of imaging findings aids in surgical planning and patient management for trigeminal nerve lipomas.
