title: Hyperdense mucoid impaction in allergic bronchopulmonary aspergillosis: CT appearance.
abstract: Allergic bronchopulmonary aspergillosis is an immunologic pulmonary disease characterised by proximal bronchiectasis with normal peripheral branchings and mucoid impactions in patients with asthma. The pathologic damage consists of mucoid impaction containing macrophages, several eosinophils, fungal hyphae, scaled-off epithelium (Curshman spirals) and calcium oxalate crystals. On CT, the mucoid impaction of the bronchial tree generally shows slightly hyperhydric density. The originality and peculiarity of our case is the presence of high-density mucoid impaction inside an atelectatic area.
