Diabetes is one of the most common non-contagious diseases in the world. This disease is the fourth or fifth cause of death in most developed countries. The relationship between tuberculosis and diabetes had been introduced years ago and diabetes is considered a threatening factor in tuberculosis in the research history. Not only tuberculosis is prevalent among diabetic persons, but also diabetes can affect the appearance of imaging of tuberculosis. This is a kind of analytic study, a case-control study, which was carried out between the years ۲۰۱۴ and ۲۰۱۵ in Zabol City. In this study, the radiographic findings from the patients suffering from pulmonary tuberculosis in diabetic patients and not diabetic patients are compared. These radiographic were handed to a radiologist and the radiologic findings of these graphs from the anatomic location (upper and lower half of the right and left bellows), Presence or absence of cavities, nodules, density and pleural involvement were recorded and compared with the diabetic and non-diabetic group. After gathering of the data using SPSS software, descriptive statistics were presented in the form of (frequency, percent) graphs and a chi-square test (p<۰.۰۵) was used to analyze and comparing of the results of diabetic and un-diabetic patients. The population of the study consisted of Chest radiographs for ۱۲۴ TB patients which ۶۱ (۴۹.۱۹ %) were suffering from diabetics. In this study, ۴۵ (۷۱.۴۳%) non-diabetic and ۴۲ (۶۵.۸۵%) diabetic patients were women (p=۰.۷). There were ۱۲ diabetic TB patients (۱۹.۶۷%) and ۳ non-diabetic- TB patients (۴.۷۶%) with the consolidation of middle part of left lung (p=۰.۰۱) and ۸ (۱۳.۱۱%) diabetic TB and ۱ (۱.۵۹%) non-diabetic TB with reticulonodular infiltration of lower part of left lung (p=۰.۰۲). There was no significant difference in the rest of the radiographic results. The findings of this study indicate that reticulonodular infiltration and consolidation of lower &middle parts of the lung in TB diabetic patients is more than in TB non-diabetic patients and diabetes can affect the findings of pulmonary tuberculosis radiography.
