Later on Bactec AFB culture of bronchial wash came back as positive for Mycobacterium tuberculosis, Later on Bactec AFB culture of bronchial wash came back as positive for Mycobacterium tuberculosis, Final sensitivity result showed pan-sensitive mycobacterium tuberculsis Final sensitivity result showed pan-sensitive mycobacterium tuberculsis

Follow-up after six weeks showed resolution of cough symptom and significant clearing of lung infiltrates on repeat chest X-ray.

Endobronchial tuberculosis is usually a complication of primary pulmonary tuberculosis mostly occurring in children, but can occur in adults. The incidence of endobronchial TB is higher in females. is usually a complication of primary pulmonary tuberculosis mostly occurring in children, but can occur in adults.

Commonest form of endobronchial TB Commonest form of endobronchial TB is mucosal erosions. is mucosal erosions. Submucosal lymph node involvement Submucosal lymph node involvement can lead to endobronchial ulceration, granulation tissue, polypoid or ulcerous lesions and local infiltration causing bronchial stenosis. can lead to endobronchial ulceration, granulation tissue, polypoid or ulcerous lesions and local infiltration causing bronchial stenosis. 1- Matthews JI; Matarese SL; Carpenter JL.

Cough is the most frequent symptom occurring in almost 97% of cases. Cough is the most frequent symptom occurring in almost 97% of cases. The most serious complication of endobronchial TB is bronchial stenosis The most serious complication of endobronchial TB is bronchial stenosis

Early diagnosis and treatment is essential in preventing the disabling complication of bronchial stenosis which can lead to morbidity and even mortality due to secondary complications.

Several treatment options have been tried to prevent bronchial stenosis including Isoniazid inhalation and systemic steroids but results are not promising.

Most authors stress the need for early bornchoscopy to diagnose the condition so that anti tuberculosis treatment is started on time to prevent serious complications of endobronchial tuberculosis.
