Radiological and Functional Findings in Presence of Bullae and Blebs
Journal Title: Journal of Clinical and Analytical Medicine - Year 2012, Vol 3, Issue 1
Abstract
Aim: Bullae and blebs are frequently associated with emphysema,but sometimes occur in absence of another associated disease. We aimed to find out the location, size of the bullae and/or blebs detected on computed tomography,accompanying radiological findings and relationship with pulmonary functions. Material and Method: Patients undergoing CT for various reasons between April 2008-May 2009 were retrospectively evaluated and 171 cases having bullae and/or blebs were included in the study.Result: Study population consisted of 125 male and 46 female patients,with a mean age of 63.88(28-90). Bullae were detected in 145(84.8%) and blebs in 112(65.5%). They were multiple in 135(78.9%) and solitary in 36(21.1%). In 27 cases all lung lobes were effected. Accompanying radiological findings were fibrosis, emphysema, peribronchial thickening, pleural thickening, parenchymal nodule, ground glass opacity and bronchiectasis Lung function tests(LFT) were noted. When bulla positive and negative groups were compared there was no significant difference in FVC% ve FEV1% , whereas FEF 25-75% and FEV1/FVC were significantly lower in bulla positive group. Bleb positive and negative groups had similar LFT values. When cases with single and multiple bullae and blebs were compared the difference was insignificant in all parameters but FEV1/FVC. Discussion: As a result presence of bullae, especially when multiple, can effect lung functions,therefore functional evaluation is crucial in cases with radiographic findings.
