Abstract:
Purpose. To illustrate the propensity of meningeal hemangiopericytoma to spread extraneurally, as a distinction to the ordinary meningioma.Patients or subjects. A patient with long history of meningeal hemangiopericytoma was reported.Methods. A case report on meningeal hemangiopericytoma with a literature review was presented.Results. The patient has multiple local recurrence as well as distant metastases.This is the first case report of metastatic meningeal hemangiopericytoma causing compression of the pancreatic head.The patient also has biopsy-proven pulmonary metastases.The patient received both local and systemic therapy.Discussion. It is important to recognize the distinctive features differentiating meningeal hemangiopericytoma from meningioma. The positive impact of clinico-pathological correlation on patient management is emphasized.
Insights
Meningeal hemangiopericytoma can spread beyond the skull, unlike typical meningiomas. This case highlights distant metastases and the importance of distinguishing these tumors for effective patient management.
Area of Science:
- Neuro-oncology
- Pathology
Background:
- Meningeal hemangiopericytoma is a rare tumor.
- It has a higher propensity for recurrence and metastasis than typical meningioma.
- Distinguishing it from meningioma is crucial for treatment planning.
Purpose of the Study:
- To highlight the extraneural spread of meningeal hemangiopericytoma.
- To differentiate meningeal hemangiopericytoma from meningioma.
- To report a unique case of metastatic meningeal hemangiopericytoma.
Main Methods:
- Case report of a patient with a history of meningeal hemangiopericytoma.
- Literature review on meningeal hemangiopericytoma and meningioma.
- Analysis of clinical and pathological findings.
Main Results:
- The patient experienced multiple local recurrences and distant metastases.
- First reported case of metastatic meningeal hemangiopericytoma causing pancreatic head compression.
- Biopsy-proven pulmonary metastases were identified.
- The patient underwent both local and systemic therapies.
Conclusions:
- Recognizing the distinct features of meningeal hemangiopericytoma is vital.
- Clinico-pathological correlation significantly impacts patient management.
- Early identification of metastatic potential is key for prognosis.
