Hepatic metastasis from a meningeal hemangiopericytoma: A case report.

INTRODUCTION: A meningeal hemangiopericytoma (MHPC) is an aggressive tumor characterized by a high rate of local recurrence and late distant metastasis. The objective of this study was to share our experience with the treatment of a MHPC and how to distinguish this tumor from a meningioma. PATIENT CONCERNS: A 62-year-old woman presented with symptoms of hypomnesia, hyperopia, and double vision for 1 month. Complete tumor excision was performed 6 years before. A biopsy sample was diagnosed as an atypical meningioma. DIAGNOSIS: MHPC with late delayed hepatic metastasis. INTERVENTION: Hepatic resection was performed initially, followed by secondary neurosurgery for complete excision of the bilateral frontal lesion 1 month later. OUTCOME: Based on the tumor pathology and consensus of oncologic surgeons, radiation therapy was initiated. Adjuvant therapy was well-tolerated and the patient remained recurrence-free at 6 months after surgery. CONCLUSION: Here, we report a case of local brain tumor recurrence and multiple hepatic metastases from a MHPC. Craniotomy combined with radical metastasectomy may be useful in such cases. Detailed immunohistochemical staining is helpful to distinguish a MHPC from a meningioma. Long-term follow-up is recommended.

Microsurgery with or without Neuroendoscopy in Petroclival Meningiomas.

AIM: This study aimed to investigate the operative procedure for neuroendoscope-assisted microscopic resection of petroclival meningioma to improve prognosis. MATERIAL AND METHODS: Twelve patients with petroclival meningioma who had undergone neuroendoscope-assisted microscopic resection at the Department of Neurosurgery, First Affiliated Hospital of Xinjiang Medical University were selected. In addition, 12 patients with petroclival meningioma who had undergone microscopic surgery were used as control. Clinical data from the 24 cases of petroclival meningioma were analyzed. RESULTS: For the neuroendoscope-assisted group, six, five, and one cases were respectively subjected to total resection, subtotal resection, and most resection. For the microscopic surgery group, two, three, and seven cases were respectively subjected to total resection, subtotal resection, and most resection. Both the total and subtotal resection rates of petroclival meningioma in the neuroendoscope-assisted group were significantly higher than those in the microscopic surgery group (p < 0.05). No difference was observed for short-term and long-term complications (p > 0.05) between the two groups. CONCLUSION: Neuroendoscope-assisted microscopic resection for petroclival meningioma can improve the total and subtotal resection rates of the tumor. Moreover, this method does not increase postoperative short-term and long-term complications.
