Value of contrast-enhanced ultrasound in deep angiomyxoma using a biplane transrectal probe: A case report

Figure 2 Scanning with a TRT33 biplane transrectal probe linear array. A: Grayscale ultrasound showed that the mass (arrows) was irregular in shape, with a layered appearance of alternating hyperechoic and hypoechoic areas inside and a clearly demarcated boundary with respect to the rectal wall (curved arrow); B: Color Doppler flow imaging showed that the dispersed intratumoral blood vessels were consistent with the layered appearance of the mass (arrows) on grayscale ultrasound; C: Transrectal contrast-enhanced ultrasound showed a laminated distribution of the contrast agent in the mass (arrows), also consistent with the layered appearance of the tumor on grayscale ultrasound; D: Transperineal core needle (arrowheads) biopsy was performed under the guidance of transrectal ultrasound.
