Carcinoma of the Cervix Metas
Ball Valve Effect on the Left Upper Bronchus
33-year-old female with known primary carcinoma of the cervix presents with infiltrating and encasing mediastinal adenopathy with severe stenosis of both the left and right main stem bronchi. The upper panels reveal hyperinflation of the left upper lobe (a,b blue arrrowheads) likely secondary to air trapping. The lower panel reveals the severe stenosis of the left main stem bronchus (c white arrowhead) with subtotal occlusion appreciated in d, (white arrowhead). This severe subtotal occlusion probably accounts for the hyperinflation secondary to ball valve mechanism
