PURPOSE We aimed to compare the intra- and interoperator variability of lobar volumetry and emphysema scores obtained by semi-automated and manual segmentation techniques in lung emphysema patients. MATERIALS AND METHODS In two sessions held three months apart, two operators performed lobar volumetry of unenhanced chest computed tomography examinations of 47 consecutive patients with chronic ...

Biopsy or necropsy specimens of lung from 28 patients with congenital heart disease and Down's syndrome were studied to establish the cause of the postoperative respiratory failure often seen in such cases. Changes in lungs seen after operation included interstitial emphysema and overdistension of peripheral air spaces, associated with hypoplastic alveoli and deficient elastic fibres in the alv...

A retrospective analysis of 57 consecutive cases with congenital cystic disease of the lung admitted to King Faisal Specialist Hospital and Research Center and King Khalid University Hospital, Riyadh, between 1985-1995 is presented. There were 37 congenital lobar emphysema (CLE), 7 cystic adenomatoid malformation (CAM), 8 bronchogenic cyst (BC) and 5 pulmonary sequestrations (PS). There were 39...

Cavitary lesions due to pulmonary tuberculosis are very rare in infants, although these may be found in older children and adolescents [1]. We report a six-month-old girl who presented with history of recurrent episodes of respiratory infections, failure to gain weight, rapid respiration and feeding difficulty since 3 months of age. Failure to thrive, respiratory distress, clubbing and decrease...
