Summary
This case study details an inflammatory pseudotumor in the choroid plexus, a rare brain tumor. The findings highlight the importance of considering this diagnosis in patients with neurological symptoms.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Inflammatory pseudotumor is a rare, benign lesion that can occur in various organs.
- Choroid plexus tumors are uncommon, with inflammatory pseudotumor being an exceptionally rare subtype.
- This report focuses on a specific case within the lateral ventricle.
Observation:
- A 73-year-old male presented with disorientation, right hemiparesis, and gait disturbance.
- Imaging revealed a well-defined, contrast-enhancing lesion in the left lateral ventricle.
- The lesion originated from the choroid plexus, causing expansion of the ventricle.
Findings:
- Histopathological diagnosis confirmed the lesion as an inflammatory pseudotumor.
- This represents one of the few reported cases of choroid plexus inflammatory pseudotumor.
- The patient had a prior history of rectal cancer surgery.
Implications:
- This case expands the understanding of rare intracranial tumors.
- It underscores the need for comprehensive differential diagnoses in neuro-oncology.
- Further research into the clinicopathological characteristics of choroid plexus inflammatory pseudotumors is warranted.
