Serial transarterial embolization for the management of unresectable malignant pulmonary hemangiopericytoma: A case report and review of the literature.

Hemangiopericytomas (HPC) are perivascular neoplasms that are rarely encountered as primary lung malignancy. Surgical resection remains the mainstay therapy of HPC. A 37-year old African American female initially presented with fatigue, chest pain and palpitations. Chest radiography showed a well-circumscribed large heterogeneous vascular mass of the right hemithorax. She underwent a CT-guided biopsy of the thoracic mass and was diagnosed with low-grade pulmonary hemangiopericytoma. High tumor vascularity burden and liver metastases precluded her from being a surgical candidate. Three years ago, she referred to our facility seeking further management. She did not tolerate systemic chemotherapy. Alternatively, she had been successfully managed with serial transarterial embolization and oral angiogenesis inhibitor to date. This therapeutic approach can be further explored for long term control of unresectable pulmonary HPC.
