comparative study of radiological pattern of pulmonary tuberculosis in diabetics versus non diabetics

ABSTRACT

Pulmonary tuberculosis continues to be a major health hazard in developing including Pakistan. Radiology plays a very important role in the case finding and diagnosis of pulomonary tuberculosis. A study was carried out to determine the radiological pattern pf pulmonary tuberculosis in diabetics versus non-diabetic adults at department of chest medicine, King Edward Medical College, Mayo Hospital, Lahore. One hundred and fifty chest radiographs were reviewed of patients [75 diabetics and 75 Non-diabetics] who were smear positive for AFB. In diabetics upper zone involvement was seen in 60% as compared to 70% in non-diabetics. No case of tuberculoma was seen in both groups, bilateral involvement was common as compared to unilateral involvement in both groups. Cavitary disease was seen in 64.4% diabetics as compared to 39.6% .In non-diabetic patients. In non-diabetics lower zone involvement was seen in 8% as compared to 14.7% in diabetics. It was concluded that majority of patients still presented with typical pattern but the knowledge of other patterns is also very important especially in diabetics where lower lung field involvement cavitary disease is commoner
