When these small nodules coalesce, they may resemble consolidation. Bulging fissure sign is seen classically in consolidation caused by Klebsiella pneumoniae infection in the right upper lobe. The images show a density posteriorly in the left lower lobe. Currently, the presence of hyperdense mucus is considered a characteristic, if not a pathognomonic, finding in ABPA[ 16 ]. Notice the central mass surrounded by hyperlucent lung blue arrow.
Mucoid impaction is a relatively common finding at chest radiography inspissated secretions within a central region of bronchiectasis are manifested.
High attenuation mucoid impaction in allergic bronchopulmonary aspergillosis
At magnetic resonance (MR) imaging, the mass may have high signal. Mucoid impaction is a relatively common finding at chest radiogra- San Antonio, San Antonio, Tex (C.S.R.); and Department of Radiology, U.S. Department of. dows) demonstrate a tubular opacity with adjacent regions of variable lucency. Mucoid impaction, also referred to as mucus plugging, mucous plugging, bronchial mucocele or bronchocele formation, refers to airway filling by mucoid secretions and can be obstructive or non-obstructive. Mucoid impaction may appear as a branching tubular opacity that is distinct.
This patient was known to have pleuritic carcinomatosis.
