The imaging manifestations of caseous pulmonary tuberculosis with type-II diabetes mellitus

ObjectiveThe aim of this study was to discuss the radiographic manifestations of type-II diabetes mellitus (DM) in patients with caseous tuberculosis (TB).MethodsWe performed a retrospective analysis of the chest radiographs and CT scans of 18 type-II diabetic patients with caseous tuberculosis, treated at Zhongnan Hospital, from January 1997 to December 2012.ResultsEighteen cases of type-II diabetic patients with caseous tuberculosis (DMTB) showed different degrees of cough, cough phlegm and hemoptysis. Imaging performance: All eighteen cases showed big flake and multiple small pieces of integration high-density shadows. All showed caseous pneumonia, and two cases also showed atelectasis. CT examination revealed a number of small hollows in the lesions. Fourteen cases of the lesions were in the right lung, one in the left lung, and three cases in the bilateral lungs. Six cases were confirmed after Sputum examination or bronchoscopy, eight cases were confirmed one month later with a variety of ineffective treatments, and the rest were confirmed through operation.ConclusionType-II diabetic patients with caseous tuberculosis mainly showed consolidation and atypical lung field lesions on chest radiographs. Becoming familiar with these features will be helpful to imaging diagnosis of DMTB.
