Neoplastic stenosis of the sigmoid descending passage with small lymphadenopathies in the perivisceral adipose tissue.
Case Discussion
Ultrasound can see changes of the colonic wall with an image "pseudo-kidney", in which the regular alternation of layers is interrupted by the neoplastic lesion hypoechoic and infiltrating.
Infiltrated and hypoechoic walls reduce the width of the lumen in which air trapped that appears hyperechoic resulting pseudo-kidney appearance.
