Abstract:
The authors describe an exophytic glioma of the pons that grew into the Meckel's cave and cavernous sinus in a 75-year-old man. Pontine gliomas should be included in the differential diagnosis of a hyperintense, complex cystic mass seen along the distribution of cranial nerve V.
Insights
This study details an exophytic glioma of the pons extending into the Meckel
Area of Science:
- Neuro-oncology
- Neurosurgery
- Radiology
Background:
- Gliomas of the pons are rare, particularly exophytic variants.
- Extension into adjacent structures like Meckel's cave and the cavernous sinus presents diagnostic challenges.
Observation:
- An exophytic glioma originating in the pons was observed to invade the Meckel's cave and cavernous sinus.
- The patient was a 75-year-old male presenting with symptoms related to cranial nerve V involvement.
Findings:
- The pontine glioma presented as a hyperintense, complex cystic mass on imaging.
- The tumor's location and appearance mimicked other pathologies affecting the trigeminal nerve (cranial nerve V) distribution.
Implications:
- Pontine gliomas should be considered in the differential diagnosis for complex cystic masses in the trigeminal nerve pathway.
- This case highlights the importance of considering rare glioma presentations in neuroimaging interpretation.
