H&E stain (200×, Fig 2A; 400×, Fig 2B) from right internal iliac artery shows transmural vasculitis with intimal thickening (asterisks) and giant cells (arrowheads). Elastic stain reveals disruption of elastic lamina (Fig 2C). AP DSA, fusiform aneurysms supraclinoid left ICA (arrowheads; Fig 2D), right ICA (arrowheads; Fig 2E). Note aneurysm clips (arrows). DSA, diminutive, irregular aorta (arrows; Fig 2F). Right common iliac artery not identified (asterisks), no flow distal left common iliac artery (arrowheads). Non-contrast head CT (Fig 2G) demonstrates acute hemorrhage (arrows).

Insights into

imaging of aortitis. a–g A 63-year-old man with a prolonged history of Takayasu arteritis. MDCTA axial images of the chest at the level of the main and left pulmonary artery (a), right pulmonary artery (b, c) and right upper lobe demonstrate substantial thickening of the pulmonary arterial wall, especially pronounced at the level of the right pulmonary artery with almost complete occlusion of the right upper lobe branch and pulmonary infarcts (d) (arrows). T1-weighted (e), T2-weighted (f) and GD-enhanced (g) MRI images emphasise the same findings as well as substantial wall oedema seen as bright signal on T2-weighted images (f) (arrows)

Imaging of

intestinal vasculitis focusing on MR and CT enterography: a two-way street between radiologic findings and clinical data. Intestinal vasculitis in a 35-year-old female with known Takayasu arteritis presenting with RLQ pain and elevated ESR. Axial contrast-enhanced CT scan (A) shows mural thickening and severe stenosis at the origin of the celiac artery (thin black arrow). Axial CT image (B) demonstrates circumferential mural thickening and submucosal edema at a single distal ileal segment (elbow arrow). MRE (C) was done following corticosteroid therapy after six days. Axial T2-W image shows complete resolution of corresponding ileal involvement (thick white arrow). Axial post-contrast T1-W image (D) displays concentric and irregular mural thickening and enhancement of abdominal aorta (black dotted oval) with double rings appearance (inner low and outer high enhancement). MR angiography (E) was performed. MIP image shows irregularity and multi-segmental stenosis at the distal abdominal aorta (thin white arrows). There is also bilateral stenosis at the origin of renal arteries (white arrowheads). The proximal segment of SMA shows irregularity and severe stenosis (white dotted oval). Abnormal dilatation of the arc of Riolan (white curved arrows) is evident, which supplies collateral flow to the SMA territory

DSA (AP/oblique) from right ICA injections (Fig 1C) confirms aneurysm of the distal A1 ACA segment. 3-D TOF MRA abdomen (Fig 1D) with bilateral internal iliac artery aneurysms (arrows), narrowing of mid-abdominal aorta (arrowheads), diffusely narrowed bilateral common and external iliac arteries (asterisks). 2-D TOF MRA abdomen (Fig 1E) shows worsening involvement of left common iliac artery (arrows), with right external and internal iliac arterial aneurysms unchanged (arrowheads).
