Abstract：Objective To discuss the clinical application value of multi-slice spiral CT (MSCT) in diagnosis of pulmonary sclerosing hemangioma (PSH). Methods MSCT features and preoperative diagnostic accuracy were retrospectively analyzed of 19 patients with pathologically proven PSHs after surgery. 9 patients were performed with routine CT scan, 2 patients were performed with directly enhanced CT scan, and 8 patients were performed with routine and enhanced CT scan. Finally, thin layer reconstruction and multiplanar reformation(MPR) were conducted to the images. Results All of 19 images in our study presented solitary pulmonary nodules or masses with a mean diameter of 23 mm and equal distribution. 8 patients (42.1%) had calcifications. 4 images (21.1%) had lobulations. 3 images (15.8%) had air meniscus signs. 4 images (21.1%) showed the tendency to grow across the pleural membranes. And only one image (5.26%) showed pleural indentation sign. 8 images (80%) conducted with enhanced CT scan showed vascular welt signs. The preoperative localization diagnosis accuracy rate was 100% and the preoperative qualitative diagnostic accuracy rate was 68% in this group. Conclusion The morphological and structural features of PSH can be seen clearly in MSCT thin layer and MPR. And welt vessel signs can be helpful to the diagnosis of PSHs. MSCT has high clinical application value in the diagnosis of PSH.
