Detection of small trigeminal neurinomas
Journal of Neurosurgery
|November 1, 1976
Summary
This study reviewed four trigeminal neurinoma cases, highlighting diagnostic methods and surgical outcomes. Pneumoencephalography effectively identified tumors, leading to successful surgical removal with no complications.
Area of Science:
- Neurosurgery
- Neuroradiology
- Oncology
Background:
- Trigeminal neurinomas are rare benign tumors arising from the trigeminal nerve.
- Accurate diagnosis and surgical resection are crucial for patient outcomes.
- Reviewing diagnostic modalities and surgical results aids in understanding trigeminal neurinoma management.
Observation:
- Four cases of trigeminal neurinoma were analyzed.
- Clinical presentation, diagnostic imaging (including lumbar puncture, EEG, brain scan, radiographs, angiography, and pneumoencephalography), and surgical outcomes were documented.
Findings:
- Pneumoencephalography, particularly with tomographic projections, accurately delineated the trigeminal nerve tumors in all four cases.
- Complete tumor removal was achieved in three patients, with near-complete removal in the fourth.
- No operative morbidity or mortality was observed in the reviewed cases.
Implications:
- Pneumoencephalography is a valuable tool for diagnosing trigeminal neurinomas.
- Surgical resection of trigeminal neurinomas can be performed with excellent outcomes and minimal risk.
- These findings support aggressive surgical management for trigeminal neurinomas.
