IF LU 001e Problem Pooja Sikka MD Ashley Davidoff MD Problem Lower Lobe Bronchiectasis, Finger in Glove and Consolidation77 year old female with history of asthma, allergic bronchopulmonary aspergillosis (ABPA) and COPDCT scout (a and magnified in b) shows lobular LLL infiltrate iof the lung Axial images show bilateral bronchiectatic airways . The LLL airways are more affected and are filled with mucus (finger in glove sign left lower image) becoming confluent and consolidative above the left hemidiaphragm right lower image). Ashley Davidoff TheCommonVein.net CXR – Hyperinflation and LLL infiltrate and Tubular Structures in the Upper Lobes77 year old female with history of asthma, allergic bronchopulmonary aspergillosis (ABPA) and COPDCXR shows hyperinflation, and consolidation in the left lower lobe silhouetting the left hemidiaphragm, with prominent bronchovascular bundles in the upper lung fields seen both on the PA and the lateral Diagnosis: Asthma Allergic Bronchopulmonary Aspergillosis (ABPA) COPDAshley Davidoff TheCommonVein.net CT Varicose Bronchiectasis ABPA The axial images of the RUL are focused on the air filled varicoid bronchiectasis within the RUL atelectasis (lime green arrow in d) The shape of the posterior subsegmental airways has varicoid shape, and hence the terminology. The axial cuts on the left at 2 different levels, are magnified on the right images. The consolidation (yellow asterisk is noted in all 4 images – solid anteriorly, with the bronchiectatic posterior subsegmental airways posteriorly. There is a small focus of mucoid accumulation in the proximal segmental airway (yellow arrowhead d) The hyperinflated RLL is marked with a teal asterisk in all 4 images . Ashley Davidoff MD TheCommonVein.net CT Atelectasis Hyperinflation and BronchiectasisABPA The coronal image is relatively anterior and hence presents as a dense consolidation of atelectasis (orange asterisk, a) In the axial images the hyperinflated RLL is seen posteriorly (teal asterisks in b and c) The region of varicose bronchiectasis is noted posteriorly (lime green arrow, c) When the net density of these 3 findings (consolidation, hyperinflated RLL and bronchiectasis in the LUL) are superimposed on CXR they present with a difficult interpretation since it is the overall net density that gets reflected.
