Objective To enhance the understanding of pulmonary hemangiopericytoma. Methods With a case report and reviewing related literatures, the etiology, clinical manifestations, radiological features,pathological features, diagnosis, treatment and prognosis of pulmonary hemangiopericytoma were discussed.Results The etiology of this rare disease remains unknown. Clinical symptoms are rare and non-specific.Radiological features show a round, homogeneous, soft-tissue mass without calcification. Pathologic feature reveals a large number of capillary lumen, and some tumors can be dressed with pseudo capsule or show infiltration growth to the surrounding tissue. The diagnosis of pulmonary hemangiopericytoma is mainly based on the imaging findings, and pathological examination is needed for final diagnosis. The best choice of treatment is surgery, combined with chemotherapy and radiotherapy.Conclusions Pulmonary hemangiopericytoma is rare and often misdiagnosed as other pulmonary diseases. More attention should be paid to improve its therapeutic effect and prognosis.
