Figure 4: Nonspecific aortoarteritis. (A) Axial contrast enhanced CT showing an enlarged mediastinal lymph node (thick arrow) and diffuse wall thickening of left subclavian artery (Thin arrow) ( B ). Volume rendered CT angiography image showing diffuse long segment narrowing of left subclavian artery (thick arrow) and abdominal aorta at the renal artery origin level as well as infrarenal segment (thin arrow) ( C ). Axial contrast enhanced CT showing diffuse wall thickening of abdominal aorta (long arrow) with luminal narrowing of the origin of superior mesenteric artery (arrow head) ( D ). Axial contrast enhanced CT showing an enlarged subcarinal mediastinal lymph node (thick arrow) and diffuse wall thickening of descending thoracic aorta (arrow head). Bilateral pleural effusions [left more than right (thin arrows)] can also be seen ( E ). Digital substraction angiography (DSA) showing diffuse long segment narrowing of abdominal aorta at the renal artery origin level and infrarenal segment (white arrow). There is a marked narrowing of the bilateral renal arteries (black arrows)
