    Notes: Abstract. The greatest difficulty in the CT diagnosis of perforated pulmonary hydatid cyst (PPHC) is the increase in the attenuation numbers following infection. Because of the solid density of infected hydatid cysts, the differentiation from an abscess or neoplasm is usually impossible. The aim of this study was to evaluate the value of “air bubble” as a new CT sign in the diagnosis of PPHC. Sixty-five patients (28 men and 37 women) with PPHC were included in the study. As a control group, 55 patients who had malignant (n = 36) or non-malignant (n = 19) pulmonary diseases were also examined. Radiological diagnosis with classical CT findings was made in only 38 of 65 patients (58.5 %) with PPHC. Air bubble sign was positive in 54 of the patients with PPHC (sensitivity 83.1 %) but only 3 of 55 patients in control group (specificity 94.5 %). When we analyzed the CT scans with classical CT findings including air bubble, the diagnosis of PPHC was made in 61 of patients (93.8 %). It is concluded that “air bubble sign” is a valuable CT finding in the diagnosis of PPHC.

    Description / Table of Contents: Résumé Les coupes sériées au scanner d'os temporal isolé ont été faites dans le plan transversal tous les 1,5mm. Le même os a ensuite été coupé tous les 3mm dans des plans parallèles à ceux du scanner. Les deux séries de coupe sont ensuite analysées de façon comparative.
    Notes: Summary Serial Computed Tomography (CT) scans of isolated temporal bones have been obtained in transverse planes at 1.5 mm intervals. Then gross anatomic sections of same temporal bones were taken at 3 mm. intervals in planes parallel to the CT scans. These CT and anatomic sections were evaluated comparatively.
