OBJECTIVES: Despite the efforts in the fight against tuberculosis (Tb) and the decrease in its incidence, severe forms persist. Tubercular pyothorax (TP), which was a frequent complication, is still difficult to treat. We studied the epidemiological, diagnostic, therapeutic and progressive aspects of this particular localization. METHODS: Retrospective study collecting all the TP reported between 1990 and 1999 in the department of pneumology in Ariana. The inclusion criterion was any patient presenting with pleural-parietal empyema of tubercular origin. We excluded patients presenting with negative bacilliferous pyothorax cultures. RESULTS: Twenty-eight cases of TP were retained among 875 cases of tuberculosis, i.e., 3.2%. The mean age of patients was of 44 years (range: 15-75) and they were moderate smokers: 27 PA. Infectious fever concomitant to a pleural syndrome was the typical clinical manifestation. In some patients empyema (3 cases) or cutaneous fistula (2 cases) were the circumstances in which the disease was discovered. Thoracic imaging is a very useful tool: standard radiography, tomodensitometry and magnetic resonance imaging permit analysis of the pleural wall and cavity. In 9 cases, pneumothorax was concomitant. A co-infection with pyogenic germs was present in 4 patients. Treatment of TP is triple; it associates specific poly-chemotherapy, thoracic draining and respiratory physiotherapy. The progression was satisfactory in the recent forms concomitant to a bacilliferous pulmonary Tb. Complications such as pleural-pulmonary after effects are inherent to the severe forms. Surgery was necessary for 9 patients (5 drainages, 2 rib resections and 2 decortications). CONCLUSION: TP is a menace for functional prognosis. Treatment is double: early, curative and effective, and preventive of Tb and its risk factors.
