%X "nIntroduction:Tuberculosis (TB) is one of the most important causes of mortality in the world. If not treated, this disease will kill 50 ¨C 65% of the patients in five years. Chest X ray has an important role in the diagnosis of TB. Diagnosis of this disease and starting the appropriate treatment interrupts tuberculosis transmission by rendering patients noninfectious. In this study, we evaluated the radiologic manifestations of patients with smear positive pulmonary tuberculosis in Zabol. "nMaterials and Methods: In this cross¨Csectional study, 325 patients with smear positive pulmonary tuberculosis from March 2004 to March 2005 were evaluated. Data were collected and analyzed using SPSS ver 15 software. "nResults: Of 325 patients with a smear positive pulmonary tuberculosis, 116 (35.7%) were male and 209 (64.3%) were female. The left upper lobe was the most frequent site involved 175 (53.8%) and the second was the right upper lobe 134 (41.2%). The most frequently observed pulmonary involved form was bronchopneumonia 242 (74.4%). Patchy consolidation was detected in 99 (30.4%) patients. Cavitary lesions and pleural effusion were observed in 68 (20.9%) and 35 (10.7%) patients, respectively. In 8 cases (2.4%) the CXR was normal. After six months treatment, the CXR of the patients were evaluated. In 90 (27.7%) patients CXRs were resolved entirely. In 169 (52%) cases CXRs were resolved slightly and in 66 (20.3%) patients, CXR did not show any changes. "nConclusion: Tuberculosis, one of the oldest diseases known to affect humans, is a major cause of death worldwide. HIV infection and other immunodeficiency states increase the prevalence of TB. It is one of the most important infectious diseases in Afghanistan (in the east border of Iran) and immigration of Afghans causes TB to become a health problem. Pulmonary TB has different radiological manifestations and CXR has an important role in the diagnosis of TB. Consolidation, cavitations and other radiological manifestations especially in the upper lobes help the diagnosis of TB. This disease is one of the most important differential diagnoses of these changes.
