Abstract
On radiographs, the shadows created by the dilated and mucus-filled bronchi have a characteristic appearance. The involvement of several second-order bronchi leads to the formation of a shadow with well-defined lobulated contours, similar to fingers in a glove, while the involvement of one second-order bronchus with expansion into the third-order bronchi gives a characteristic Y-shaped (or V-shaped) configuration, with the leg of the Y pointing toward the hilum [1]. For suchlike mucoid impactions of bronchi, the terms “linear toothpaste shadows” and “club-like shadows” were also used. The term bronchocele is also known. Judging by clinical examples, cases of the disease, which is now called allergic bronchopulmonary aspergillosis, have been described. A similar picture is obtained on computed tomograms, but with better detailing of pathological changes (↑). The gloved fingers sign occurs in obstructive bronchial lesions that did not lead, however, to the formation of atelectasis (endobronchial tumors, foreign bodies, bronchial malformations) and in inflammatory lesions of the bronchi leading to the formation of bronchiectasis (primarily obstructive bronchopulmonary aspergillosis and cystic fibrosis).
