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

case_images: 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].
case_images: The radial ultrasound of rectum showed vascular signal in the submucosa of anterior wall of rectum

case_images: 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].
case_images: Application of pulse Doppler confirmed the venous nature of the outflowing vessel in the anterior wall of rectum

case_images: 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].
case_images: Linear endoscopic ultrasound showed a submucosal vascular lesion in the anterior wall of rectum supplied by an inflowing artery

case_images: 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].
case_images: A biopsy of the lesion showed numerous dilated vascular spaces within lamina propria and submucosa
