Colonoscopy showed markedly dilated blood vessels in the sigmoid mucosa (Fig. 1).
Computed tomography. The mucosal wall from the sigmoid colon to the rectum is thickened and surrounded by fatty tissue enhancement. Typical multiple calcified foci (arrows) are also seen

Venodilation with associated thrombosis in the dilated veins and multiple calcified foci associated with phleboliths were also detected (Fig. 2).
Magnetic resonance imaging. T2-weighted imaging (a1 coronal plane, a2 sagittal plane) shows thickened wall of the sigmoid colon and rectum and fatty tissue hyperplasia. Diffusion-weighted imaging (b coronal plane) show tortuous and dilated vessels in the fatty tissue

Magnetic resonance imaging (MRI) also showed thickened wall from the sigmoid colon to the rectum, with tortuous and dilated vessels in the fatty tissue (Fig. 3).
