Liver metastasis of meningeal hemangiopericytoma: a study of 5 cases
Mesenchymal tumors in the liver, whether primary or metastatic, are rare. Meningeal hemangiopericytoma (HPC) is characteristically associated with delayed metastasis and the liver is one of the most common sites. Despite its consistent histological features, a pathological diagnosis of HPC in the liver is sometimes not straightforward due to its rarity and usually remote medical history of the ...
متن کاملSpinal Hemangiopericytoma Which Needed Intraoperative Embolization due to Unexpected Bleeding
Spinal intradural hemangiopericytoma is a very rare tumor and can be characterized by massive bleeding during surgeries, frequent recurrence, and metastasis. However, definite radiologic differential points of hemangiopericytoma are not known. We describe an unexpected hemangiopericytoma case with large bleeding and management of the tumor. A 21-year-old man visited complaining of progressive n...
متن کاملSpinal metastasis from malignant meningeal intracranial hemangiopericytoma: one-staged percutaneous Onyx™ embolization and resection - a technical innovation
BACKGROUND We are the first to report one-staged resection of a spinal metastasis from malignant cranial hemangiopericytoma after preoperative Onyx™-20 embolization by direct percutaneous puncture.Spinal metastases from cranial hemangiopericytoma are extremely rare. Surgical morbidity of these highly vascularized tumours results mainly from excessive blood loss. Preoperative embolization of hyp...
متن کاملMetastatic Intracranial Hemangiopericytoma to the Spinal Column: A Case Report
Intracranial hemangiopericytoma (HPC) is a rare brain tumor with aggressive biologic behavior associated with high recurrence rate and often with extracranial metastasis. The most common sites of extracranial metastasis of the intracranial HPC are the long bones, lung, liver and abdominal cavity in the order of frequencies. Extracranial metastases usually occur long after the initial diagnosis ...
متن کاملPrimary intracranial meningeal and spinal hemangiopericytoma: radiologic manifestations.
Meningeal hemangiopericytomas are rare but aggressive tumors. All eight patients in this series developed recurrences, three with distant metastases. In six patients a lytic destructive lesion of bone was evident. CT scans in three patients demonstrated diffusely enhancing lesions. No tumor calcification was present. In five of six patients angiography was characterized by multiple irregular tu...
