CT Findings of Tuberculous Pneumonia in Diabetic Patients: Comparison with Tuberculosis in Nondiabetics

Objective To evaluate the CT findings of pulmonary tuberculosis in diabetic patients compared with patients without underlying disease. Methods The chest CT scans of pulmonary tuberculosis in 23 diabetic patients(M : F=21 : 2 ; mean age, 59 yrs.) and in 24 nondiabetic patients(M : F=12 : 12 ; mean age, 48 yrs.) were retrospectively analyzed by two radiologists ; decisions were reached by consensus. Results The frequencies of consolidation(100%, 42%), inhomogeneity of consolidation(70%, 21%), multiple small low-density areas(52%, 13%), cavitation(70%, 25%), multiple small cavity(35%, 4%), bizarre-shaped cavity(22%, 0%), air-bronchogram(95%, 54%) were significantly more common in pulmonary tuberculosis in diabetic patients than in nondiabetic patients(p
