Abstract :
Objective: To report the use of two techniques (radiosurgery and
en bloc vertebrectomy) on the same patient for the treatment of two metastases in different sites of the spine arising from intracranial hemangiopericytoma. Intracranial hemangiopericytomas are rare, comprising approximately 2.4% of meningeal tumors and <1% of all tumors of the central nervous system. Metastases to the spine are even rarer: The largest case series reported in the literature has 5 and 7 cases. Methods: A 37-year-old man diagnosed with intracranial hemangiopericytoma was referred for a metastatic lesion in T12 and underwent en bloc resection using the Tomita technique. Results: The disease evolved with a metastasis to T2 treated by radiosurgery with 1600 cGy. The patient died 1,706 days after the en bloc resection of T12 and 1324 days after the radio-surgery of T2, and no recurrence occurred in these locations due to progression of the systemic diseases (liver and central nervous system). Conclusion: This is the first case reported in the literature in which two different techniques were used to treat metastatic lesions in the spine from an intracranial hemangiopericytoma and is unique for its use of two treatments in the same patient. Level of evidence: V, case report
