Introduction: The diagnosis of bronchiectasis (BC) is based on high resolution chest computed tomography (HRCT). There are few reports on the correlation between HRCT images and prognosis scores.

Objectives: Assess the correlation between radiological features of BC and prognosis scores(FACED and BSI)

Methods: Retrospective comparative study including 111 patients with BC confirmed by HRCT in pulmonary department 1, Abderrahmane Mami Hospital.  Distribution and  type of BC on HRCT were compared according to FACED and BSI scores.

Results:Mean age of our population was 55 ± 19 years .Diffuse BC observed on HRCT were more likely correlated with higher FACED score ( 4.26 ± 1.53 vs 2.16 ± 1.5 ; p < 10-3 ) . A lower FACED score was found in localized lesions (2.19 ± 1.51 vs 4.26 ± 1.52, p<10-3). Moreover, 58.8% of patients with localized BC on HRCT belonged to mild FACED group(vs moderate FACED group = 27.7% and vs severe FACED group= 5.7%;p= 0.001) .Among patients with extensive signs on HRCT, 94.3% were correlated with severe FACED group  (p< 10-3). No significant correlation was established between the distribution of lesions on HCRT and global BSI score. Although,76.4% of patients with diffuse lesions belonged to severe BSI Group (vs BSI mild group=45.5%;p = 0.039).There is no significant correlation between the type of bronchiectasis on HRCT and BSI or FACED score.

Conclusion:In our study, extensive lesions on HRCT were associated with a higher FACED score without significant correlation with BSI score. The type of lesion seems not to influence the prognosis of the disease based on BSI and FACED scores .
