Endoscopic findings of the colon (a cecum, b sigmoid colon) and pathological findings of the sigmoid colon (c) when the case was diagnosed as EGE. Computed tomography scan showing wall thickening of the aortic arch, brachiocephalic artery, right and left subclavian artery and left common carotid artery as well as dilation of the ascending aorta (d, e).

On a pathological examination of biopsied specimens, many eosinophils were found to have infiltrated the colon mucosa (Fig. 1a-c). Three-dimensional computed tomography (CT) revealed wall thickening of the aortic arch, brachiocephalic artery, right and left subclavian artery and left common carotid artery and dilation of the ascending aorta (Fig. 1d, e). Positron emission tomography (PET) also showed the FDG uptake in the above arteries (Fig. 1f). During the period of this hospitalization, she underwent total colonoscopy for the assessment of EGE, which showed no edema and erosion with a little vessel augmentation in the ascending and transverse colon (Fig. 1g, h).
Reverse transcription-polymerase chain reaction (RT-PCR) expression of inflammatory factors associated with Th1 (IL-1beta, TNFalpha and interferon gamma), Th2 (IL-4, IL-5 and IL-13), Th17 (IL-17) and regulatory T cells (IL-10, FOXP3) in biopsied specimens of the colon before and after PSL treatment for EGD. IL-4 and IL-13 were not detected

We examined the expression of inflammatory factors associated with Th1 (IL-1beta, TNFalpha and interferon gamma), Th2 (IL-4, IL-5 and IL-13), Th17 (IL-17) and regulatory T cells (IL-10, FOXP3) in biopsied specimens of the colon before and after the PSL treatment for EGE using reverse transcription-polymerase chain reaction (RT-PCR) (Fig. 2).
