- Abstract
The authors investigated the clinical and radiological features and the treatment strategy for bone metastasis from a rare tumor, intracranial meningeal hemangiopericytoma. The clinical presentations and characteristic imagings were retrospectively reviewed in 15 bony metastatic lesions of four patients with this tumor. All four cases were initially diagnosed as atypical meningioma, and all of the bone metastases developed more than 10 years after the initial intracranial surgery. The common symptom induced by the metastatic lesions was pain. On plain roentgen films and computed tomography (CT), the involved bones showed thinning and expansion. On bone scintigraphy, a “cold-in-hot” appearance was typically observed. The clinical and radiological findings were diagnosed as bone metastasis from intracranial meningeal hemangiopericytoma. The prognosis after bone metastasis was relatively short compared to the long duration before bone metastases, because of the coexistence of other, visceral, metastasis. Combined with effective radiation therapy, surgical intervention for bone metastasis of this tumor should be carefully considered.
