CT Image Feature Analysis of Pulmonary Sclerosing Hemangioma

objective: To study the CT feature of pulmonary sclerosing hemangioma (PSH), and improve the diagnosi's accuracy and differential diagnosis of PSH by CT scanning. Methods: The CT images of 18 PSHs confirmed operation and pathology were retrospectively analyzed, and 11 cases followed enhanced CT scanning. Result: It is very difficulty in preoperative diagnosis and main group of PSH is middle-aged women. Of those 18 cases, female were found in 17 cases (17/18, 94.44%), and patients aged in 43-70 years were found in 15 cases (15/18, 83.33%) and whose tumors were located in the left lower lung zone accounted for 50.00%. The tumors were round with clear edge (18/18, 100/%), were slightly lobulated (3/18), had punctate calcification (6/18, 33.33%), and had mediastinal lymph node (1/18). All cases were without cavity, pleural sag and metastasis, and vascular incisura. The CT values of observed cases were between 26-40 Hu. Among 11 cases followed enhanced CT scanning, 10 cases showed obvious enhancement and delay enhancement to a degree, and the CT values were increased over 46-60 Hu. Conclusion: The CT scanning is helpful for the diagnosis of PSH. Enhanced CT could be helpful to diagnosis,
