- Abstract: Objective To analyze application value of multi-slice spiral CT (MSCT) plain scan and enhanced scan in diagnosis of pulmonary sclerosing hemangioma (PSH). Methods MSCT plain scan and enhanced scan images from 14 patients who were confirmed with PSH were analyzed. The imaging findings such as location, size, shape, margin, density of lesions, enhancement features, conditions around lesions, and the presence or absence of hilus pulmonis and mediastinal lymphadenectasis were observed. Results All the 14 cases were single isolated lesions with lesions size of 1.1 cm×1.2 cm-4.0 cm×5.6 cm. There were 11 cases with uniform lesion density, showing soft tissue density shadow and 3 cases with uneven lesion density, showing small patchy slightly low-density area. The enhanced scan showed that there were 11 cases with uniform density and uniform enhancement, and 3 cases with uneven enhancement. After lesions enhancing, all 14 cases have moderate enhancement in arterial phase. With time delay, enhancement amplitude was increased. After the thin-layer reconstruction and multi-plane reconstruction, there were 12 cases with clear lesion margin and no satellite lesions or pleural indentation sign in surrounding lung fields. There were 2 cases with tail sign in leading edge, 3 cases with halo sign in border, 10 cases with welt vascular sign, and 4 cases with air crescent sign. There was only 1 case with hilus pulmonis and mediastinal lymphadenectasis in the first diagnosis. There were 7 cases diagnosed with PSH, 3 cases diagnosed with inflammatory pseudotumor, 1 case diagnosed with tuberculoma, 1 case diagnosed with hamartoma, and 2 cases diagnosed with peripheral lung carcinoma. Conclusion MSCT plain scan and enhanced scan can further show characteristic features of PSH lesions and improve accuracy of preoperative diagnosis.
