The Differential Diagnosis of Two Cases of Chronic Periaortitis
Figure 2
(a) Contrast-enhanced CT imaging showed diffuse thickening of the aortic arch, with enhanced mediastinal connective tissue. ((b), (c)) Gadolinium-enhanced MRI showed low intensity in the T2-weighted sequence (b) and high intensity in the diffusion-weighted sequence (c), suggesting the presence of inflammation. (d) A biopsy of the tissue, using a mediastinal scope, revealed infiltration by inflammatory cells, but no bacteria. (e) A contrast-enhanced CT image 2 weeks after starting the glucocorticoid therapy.
