Abstract:
Objective To study the CT features of pulmonary sclerosing hemangioma(PSH),so that to improve the imaging diagnostic abilities.Methods 21 cases pathologically proven PSH were included in this retrospective article. Imaging features were compared with pathological results.Results (1)The disease mainly occurred in female patients between 30～50 years old; (2)On CT, the lesion presented as well-defined, round and oval shaped mass or nodule;(3) A homogeneous soft-tissue mass on unenhanced CT; calcification was found in some lesions; in 2 cases, cystic-like area was found within large tumors(≥5cm); (4)Homogeneous or heterogeneous enhancement after contrast administration; on delayed phase scans, some of them demonstrated late enhancement;(5)The seemingly characteristic air-trapping zone, vessels at its periphery and a tail sign were found in 4, 5, 7 cases respectively. Conclusion PSH should be considered in young and middle-aged female patients, with the characteristic presence of air-trapping zone, vessels at its periphery and a tail sign within images (especially on CT). And the disease can be preoperatively diagnosed combined with the clinical features with above the aforementioned features.
