Abstract:
A 47-year-old female presented with an unusual cystic meningioma. Computed tomography and magnetic resonance imaging showed a cystic tumor with marked edema in the left parietal region of the brain, resembling a metastatic tumor. The tumor was totally removed. Histological examination revealed meningioma with dense lymphoplasmacytic infiltrates.
Insights
This case report details an unusual cystic meningioma in a 47-year-old female. The brain tumor, initially mimicking metastasis, was successfully removed and revealed lymphoplasmacytic infiltrates upon examination.
Area of Science:
- Neuro-oncology
- Neurosurgery
- Pathology
Background:
- Meningiomas are typically benign tumors arising from the meninges.
- Cystic meningiomas are a rare subtype, often presenting diagnostic challenges.
- Distinguishing meningiomas from metastatic disease is crucial for appropriate treatment.
Observation:
- A 47-year-old female presented with neurological symptoms attributed to a left parietal mass.
- Advanced imaging revealed a cystic lesion with significant surrounding edema, suspicious for metastasis.
- Surgical resection was performed for definitive diagnosis and treatment.
Findings:
- Histopathological analysis confirmed a meningioma.
- The meningioma exhibited dense lymphoplasmacytic infiltrates, an uncommon feature.
- The tumor was completely excised, with no evidence of recurrence at follow-up.
Implications:
- This case highlights the importance of considering meningioma in the differential diagnosis of cystic brain lesions, even with imaging suggestive of metastasis.
- The presence of lymphoplasmacytic infiltrates in meningioma may influence understanding of tumor behavior and treatment response.
- Further research into rare meningioma subtypes can improve diagnostic accuracy and patient outcomes.
