Primary mucosal-associated lymphoid tissue extranodal marginal zone lymphoma of the bladder from an imaging perspective: A case report

Figure 1 Ultrasonographic findings of the lesion. A and B: A large homogeneous hypoechoic mass was detected in the bladder (arrows), with an unclear boundary and irregular shape. There were fine linear echogenic strands distributed inside; C: Color Doppler flow imaging showed that there were rich blood flow signals in the mass; D: Spectral Doppler ultrasound imaging showed the artery spectrum detected within the mass (Vmax = 22.9 cm/s, resistance index: 0.57).
