ABSTRACT
BACKGROUND Bronchiectasis and cavitation are key features of acute and chronic pulmonary infections. Cavitary lesions may carry unfavourable prognosis with regard to complete restoration of pulmonary function in few patients. OBJECTIVES To evaluate type and site of bronchiectasis, its relation with cavity formation on computed tomography and providing an insight to sorting out subjects suited for physiotherapy. A radiological sign-“Feeding bronchus sign” has been discussed with reference to bronchiectasis, its origin, natural course and a suggestion of guarded future management and rehabilitation. METHODS Total 150 chest CT scans with presence of cavity and bronchiectasis were retrospectively reviewed and followed up for type, site of bronchiectasis, signs of active infection, site of cavity and presence of “feeding bronchus sign”. Final diagnosis was confirmed by sputum sample, acid-fast bacillus test or culture or polymerase chain reaction. RESULTS Out of 150 cases, 70 (46%) had chronic and 80 (53%) had active infection. 33 (22%) had solitary and 117 (78%) had multiple cavities. 37 (34.6 %) patients had cylindrical, 11 (7.3 %) had varicose, 27 (18%) had cystic bronchiectasis, 23 (15.3%) had cylindrical and varicose, 19 (12.6%) had cylindrical and cystic and 33 (22%) had all three types. “Feeding bronchus sign” was observed in 102 (68%) patients. Radiological evidence of disease progression was seen in 21 patients, improvement in 19 and no change in 17 on follow-up CT. CONCLUSION Patients with positive “Feeding bronchus sign” are at risk for increased disease transmission and secondary opportunistic infections. Improvement and maintenance of quality of life is ultimate goal of management. Apart from antibiotics, pulmonary rehabilitation also plays an important role in cavitary lung disease
