Abstract:
Objective To analyse the CT imaging characteristics of solitary pulmonary tuberculous cavity in order to improve its diagnosis level.Methods 29 cases of pulmonary tuberculous cavities comfirmed by pathology or operation.All the patients were underwent examination of contrast-enhanced CT.Results 29 cases were all solitary pulmonary cavities,93%(27/29) were located at the superior lobe of lung.The average diameter was 23.5 mm.73% of the cavities were round or similar round.The majority of the cavities (82%,24/29) were less or no lobulated;76%(22/29) were thick cavities and 51%(15/29) were less smooth both in and outside the cavities.The cavities were less enhancement.All cases along with satellite nodules.Conclusion The pulmonary tuberculous cavities are majority thick cavities.The important points for tuberculous cavities to diffierent from lung cancer and other disease cavities are:are there any satellite nodules along with the cavites,lobulated or not,the growth of CT enhancement of cavitied before and after enhancement.
