Abstract:
Rhabdoid meningioma is a rare variant of meningioma, often found in tumour recurrences. We report a 55-year-old woman with a history of intraventricular fibroblastic meningioma, who developed headache and tinnitus 5 years after complete resection of the initial tumour. Imaging confirmed a recurrent tumour in the intraventricular location. Histological analysis revealed rhabdoid meningioma. We reviewed the literature and were unable to find any previously reported cases of intraventricular rhabdoid meningioma.
Insights
Rhabdoid meningioma, a rare tumor variant, can occur in recurrences. This case presents the first reported instance of intraventricular rhabdoid meningioma following a fibroblastic meningioma.
Area of Science:
- Neuro-oncology
- Pathology
- Neurosurgery
Background:
- Meningiomas are tumors arising from the meninges.
- Rhabdoid meningioma is an aggressive, rare variant.
- Intraventricular meningiomas occur within the brain's ventricles.
Observation:
- A 55-year-old woman presented with headache and tinnitus 5 years post-resection of an intraventricular fibroblastic meningioma.
- Imaging revealed a recurrent intraventricular tumor.
- Histological examination confirmed the presence of rhabdoid meningioma.
Findings:
- This represents the first documented case of intraventricular rhabdoid meningioma.
- The tumor recurred as a different histological subtype.
Implications:
- Highlights the potential for meningioma recurrence with varying histology.
- Suggests the need for vigilance in monitoring intraventricular meningioma survivors.
- May inform future diagnostic and treatment strategies for rare meningioma variants.
