Tuberculosis is a public health problem. The objective of our study is to describe the clinical, biological and radiographic aspects of bacteriologically confirmed pulmonary tuberculosis. This is a retrospective descriptive study of 209 patient files presenting a first episode of bacteriologically confirmed pulmonary tuberculosis hospitalized at the Phtisiology Department of the university hospital center of rabat from January 2014 to January 2016. The population of the study is made up of 54% of men and 46% of women, a sex ratio of 1.17. The average age of patients is 39 years old. The notion of recent tuberculosis contagion is found in 7.17% of patients and the notion of active smoking is noted in 33.9% of patients. Cough was present in 79.4% of cases and haemoptysis was noted in 22% of cases. Weight loss (91.8%) and fever (88.5%) are almost constant. Anemia is found in 79.4% of cases, it is hypochromic microcytic in the majority of cases. The average hemoglobin level is 9.3 g / dl. HIV serology was positive in 7 cases (3.3%). Radiologically, lesions are bilateral in 55.5% of cases and diffuse in 30.1%. The alveolar opacities are found in 43.5% of the cases and the excavated lesions are observed in 33.9% of the cases. Pneumothorax revealed the diagnosis in 11.4% of cases. The average diagnostic delay is 2 months. The diagnosis was mainly based on the presence of AFB in the direct examination of sputum (in 91.8% of cases). The purpose of this study is to unravel the problem of delayed diagnosis of pulmonary tuberculosis and to insist on the active search for tuberculosis in the immunocompromised field.
