Mucoid impaction of upper lobe bronchi in the absence of proximal bronchiectasis

Mucoid impaction is a complication of asthma and is frequently recurrent in patients with allergic bronchopulmonary aspergillosis (ABPA). This report describes a patient with asthma and recurrent bilateral well-circumscribed densities on chest roentgenogram in the absence of ABPA. Recognition of this clinical presentation may avoid the need for invasive diagnostic procedures or steroid therapy.
