This LearningRadiology chest case highlights the 'finger-in-glove' sign, a classic radiographic appearance of mucoid impaction in central bronchi, commonly caused by allergic bronchopulmonary aspergillosis (ABPA). Recognition is key to prompt diagnosis and management.

• The 'finger-in-glove' sign represents branching tubular opacities from mucoid impaction, typically seen in ABPA but also in other causes of bronchial obstruction.
• This is an educational case review from a blog, not a formal study; no sample size or quantitative data are applicable.
