Abstract:
Objective To analyze the imaging features of primary pulmonary hemangiopericytoma,and to provide a helpful method for clinical diagnosis.Methods Retrospectively analyze the CT and MRI characteristics of 3 cases with pathologically proved primary pulmonary hemangiopericytomas.Results All cases manifested as solitary massive tumors.On plain CT scans,the tumors were heterogeneous,well and sharply circumscribed.On contrast-enhanced CT scans,the tumors were apparently enhanced and the abnormally enhanced vasculars could be seen.On MRI scans,the tumors had inhomogeneous signal intensity and the vascular flowing-void effect could be seen.Conclusion Solitary tumor of massive volume,abnormally enhanced vasculars on contrast-enhanced CT and the vascular flowing-void effect on MRI are imaging features of primary pulmonary hemangiopericytomas.
