Abstract:
We present a case of a xanthogranuloma of the lateral ventricle choroid plexus in association with focal areas of abnormal T2 signal in the tegmentum of the pons as well as within the middle cerebellar peduncles. The characteristic MR appearance of this rare entity is described along with a pathologic basis suggesting an association with posterior fossa lesions.
Insights
We describe a rare xanthogranuloma in the brain's lateral ventricle choroid plexus. This finding was associated with abnormal signals in the pons and cerebellum, suggesting a link to posterior fossa lesions.
Area of Science:
- Neuropathology
- Neuroradiology
- Neuroscience
Background:
- Xanthogranulomas are rare tumors.
- Choroid plexus involvement is uncommon.
- Posterior fossa lesions require careful evaluation.
Observation:
- A case of xanthogranuloma in the lateral ventricle choroid plexus is presented.
- Associated T2 signal abnormalities were noted in the pons and middle cerebellar peduncles.
- The magnetic resonance (MR) imaging characteristics of this rare entity were analyzed.
Findings:
- The MR appearance of the xanthogranuloma was characteristic.
- Pathologic analysis suggested an association with posterior fossa lesions.
- The findings highlight a potential link between choroid plexus xanthogranulomas and cerebellar/pontine abnormalities.
Implications:
- This case expands the understanding of xanthogranuloma presentations.
- It emphasizes the importance of considering posterior fossa involvement in similar cases.
- Further research may elucidate the underlying pathophysiology connecting these findings.
