  • Title: A Case Report of Meningeal Hemangiopericytoma: A 9-Year Journey from the Brain to the Spine.
    Author: Sweid A, Noureldine MHA, Nasser S, Badra M, Saikali I.
    Journal: World Neurosurg; 2019 Feb; 122():459-463. PubMed ID: 30447454.
    Abstract:
    BACKGROUND: Hemangiopericytomas (HPCs) are rare and aggressive vascular mesenchymal tumors. Unlike meningiomas, which have a similar radiologic appearance, these tumors have a higher risk of local recurrence after resection, and distant metastasis can reach up to 23%. Metastases to the vertebral bones from an intracranial HPC are very rare, with so far only 9 cases reported in the literature. CASE DESCRIPTION: We present the case of a 46-year-old man who was surgically treated for a presumed left parieto-occipital falx meningioma in 2008. He presented 9 years later with a thoracic vertebral mass that was causing relentless pain. Reexamination of the cranial pathology allowed correction of the diagnosis performed in 2008 to a meningeal HPC, and the spinal lesion was confirmed after surgery to be a metastatic tumor. CONCLUSIONS: The literature lacks randomized controlled trials and large studies defining the natural history of HPC to draw clear recommendations for a precise management of the disease. However, en bloc resection followed by radiation therapy seems to provide the optimal treatment for a long disease-free survival.
