A case of sclerosing hemangioma surrounded by emphysematous change

A 44-year-old woman presented with high-grade fever. Chest radiography showed a 30 mm solitary pulmonary mass in the left lower lobe. Chest CT revealed a well-defined solid mass in the left lower lobe. On contrast-enhanced CT, the mass showed homogeneity and mild enhancement. There was an emphysematous portion in the surrounding lung parenchyma. The patient underwent partial lobectomy of the left lower lobe. The final diagnosis of sclerosing hemangioma with abundant vasculature was confirmed pathologically. Pulmonary sclerosing hemangioma is a rare benign neoplasm. Some cases have been reported in which sclerosing hemangioma is surrounded by air spaces. We suggest that the air spaces around the tumor were formed by not only peritumoral bleeding but also a check-valve effect of the compressed bronchus.
