Bronchiolectasis
Bronchovascular Bundle Thickening –
Polyarteritis Granulomatosis (PGA)
aka Wegener’s Granulomatosis)
CT in the coronal plane with a focus on the left lower lobe shows bronchiolectasis and peribronchial thickening of the distal airway of the left lower lobe resulting from the associated vasculitis

Bronchovascular Bundle Thickening –
Pre and Post Treatment
CT of the proximal bronchovascular bundle in the coronal plane shows peribronchial thickening in the superior segment of the right upper lobe resulting from the associated vasculitis prior to medical therapy (above) and following therapy (below) showing significant improvement in the degree of bronchovascular thickening

Arteritis and Aneurysms of the
Interlobar and Interlobular Left Renal Artery
Angiography of the proximal left renal shows extensive narrowing and aneurysmal changes of the interlobar and interlobular branches of the left renal artery.
