Colonoscopy showed bluish reddish elevated nodular lesions limited to distal rectum [Figure 1 and Video 1].
Magnetic resonance imaging of rectum showed hyper intense signals in the anterior wall (green arrow)

MRI of rectum showed hyper intense signals in the anterior wall [Figure 2]. In this case the diagnosis was suspected by endoscopic appearance and MRI and continuous color Doppler EUS of the lesion provided additional information of presence of a vascular lesion [Figures 3-5, Videos 2 and 3].
The radial ultrasound of rectum showed vascular signal in the submucosa of anterior wall of rectum

The radial ultrasound was able to demonstrate vascular signal in the submucosa of anterior wall of rectum [Figure 3]. Linear EUS showed a submucosal vascular lesion in the anterior wall of rectum supplied by an inflowing artery [Figure 5 and Video 3]. In this case the diagnosis was suspected by endoscopic appearance and MRI and continuous color Doppler EUS of the lesion provided additional information of presence of a vascular lesion [Figures 3-5, Videos 2 and 3].
Application of pulse Doppler confirmed the venous nature of the outflowing vessel in the anterior wall of rectum

Application of pulse Doppler confirmed the venous nature of the outflowing vessel [Figure 4]. In this case the diagnosis was suspected by endoscopic appearance and MRI and continuous color Doppler EUS of the lesion provided additional information of presence of a vascular lesion [Figures 3-5, Videos 2 and 3].
Linear endoscopic ultrasound showed a submucosal vascular lesion in the anterior wall of rectum supplied by an inflowing artery

Linear EUS showed a submucosal vascular lesion in the anterior wall of rectum supplied by an inflowing artery [Figure 5 and Video 3]. In this case the diagnosis was suspected by endoscopic appearance and MRI and continuous color Doppler EUS of the lesion provided additional information of presence of a vascular lesion [Figures 3-5, Videos 2 and 3].
A biopsy of the lesion showed numerous dilated vascular spaces within lamina propria and submucosa
