DSA findings and interventional therapy of pulmonary sclerosing hemangioma complicated by massive hemoptysis: report of one case with literature review

Objective To discuss DSA findings of pulmonary sclerosing hemangioma(PSH) and to evaluate the interventional embolization therapy in treating PSH.Methods The clinical data of one patient with PSH in association with massive hemoptysis,including DSA findings and the results of embolization treatment,were retrospectively analyzed.The relevant medical literature of PSH was reviewed.Results On DSA the PSH lesion was mainly characterized by spherical nodule with a smooth border.Remarkable at the tumor’s periphery could be seen at the early arterial stage,which became inhomogeneous and gradually deepen in color along with the time passing,taking a form of progressive staining pattern.Immediately after the embolization of the involved bronchial artery was accomplished the tumor as well as the tumor-feeding arteries disappeared,and the hemoptysis ceased as well.The lesion was finally proved to be pulmonary sclerosing hemangioma by both surgery and pathology.Blood transfusion was not needed during the operation.Conclusion Pulmonary sclerosing hemangioma carries most characteristic imaging features on DSA.Interventional transarterial embolization is of great value in controlling the clinical bleeding and reducing the blood loss during operation.
