[Tuberculosis of the lung bases].
BACKGROUND
Tuberculosis is a major public health problem in Morocco. Tuberculosis of the lung bases is a rare and atypical form and raises real diagnostic problems.


METHODS
We report a retrospective study of 21 cases of basal pulmonary tuberculosis, collected at the service of respiratory diseases in Ibn Rushd hospital in Casablanca between 2004 and 2015 (11 years).


RESULTS
From a total of 21 patients having basal pulmonary tuberculosis, 13 (62%) were women versus eight men (48%), the average age was 33 years. The average time of diagnosis was 25 days. The disease was unilateral in 20 cases (95%). The right lower lobe was the most frequently affected (71%). Inhomogeneous opacities (66%) and consolidation (28%) were the main radiological findings. Associated comorbidities were dominated by diabetes in six cases (28%). Bronchoscopy had recovered thickening spurs in eight cases, endobronchial granules in seven cases and bronchial inflammation in six cases. Bronchial biopsies had found a necrotizing granulomatous inflammation tuberculoide in seven cases (33%). The smear was positive in sputum in three cases (14%), in the bronchial aspirate in four cases (19%), in induced sputum in one case (4.7%) and in post-bronchoscopic sputum in six cases (28%). The antituberculous treatment was started in all patients with good clinical and radiological evolution.


CONCLUSIONS
The basal localization of the pulmonary tuberculosis is misleading; source of diagnostic delay, hence the need to think about it especially in patients with comorbidities.
