| Summary: | 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. |
