Abstract:
A case of bone metastase secondary to intracranial anaplastic hemangiopericytoma (AHPC) was reported. The characteristics of the disease were analyzed on the basis of clinical symptoms and imaging examinations, especially bone imaging examination and pathology. The understanding of intracranial AHPC bone metastasis was deepened by literature review. Bone metastases are common in most malignant tumors, but intracranial AHPC, which is a rare central nervous system tumor, has an extremely low bone metastasis potential. In the present case, the multiple lesions of bone metastasis from intracranial AHPC were detected through a whole body bone imaging examination. Thus, whole body bone scans should be regarded as important examination tools for patients with malignant tumors during follow-up, especially patients with rare bone metastasis, because the scans have a key value in early detection, clinical staging, and treatment decision.
