RESUMEN
Objective To explore MSCT findings of pulmonary tuberculoma.Methods MSCT data of 62 patients with pulmonary tuberculoma confirmed by clinical and pathological results were analyzed retrospectively.Results Of the 62 patients,64 lesions were detected with single in 60 cases and multiple in 2 cases.The MSCT signs showed as follows:circumscribed round,oval,egg-like or irregular nodules or masses,size ranging from 2-3 cm,cavity in 31 lesions,calcification in 25 lesions,pleural indentation sign in 45 lesions and pleural tail sign in 1 2 lesions.Conclusion The MSCT features of pulmonary tuberculoma are relatively specific such as the multiple patch calcifications within mass,calcification of the whole mass and semilunar cavity on the lateral side of the hilum.The MSCT is a valuable examination for the accurate diagnosis of pulmonary tuberculoma.
RESUMEN
Objective To explore MSCT appearances of lung lacerating injury.Methods The MSCT findings of lung lacerating injury in 31 patients were analyzed retrospective.Results The lung lacerating injury of the 31 cases with 67 lesions in total was found,18 of whom were located on the back side of lung near the pleura,11 of whom had solitary lesion and 20 of whom had multiple ones. The MSCT findings included lung cavity in 9 eases,liquid airbag cavity in 1 7 and lung hematoma in 5 .The pulmonary contusion with different degrees was found in all 3 1 cases.Dynamic observation showed the cavities and hematoma could be transformed into each other.Conclusion MSCT is the best method for diagnosis and observation of lung lacerating injury and helpful for the guide of clinical treatment.
