Omental Band: New sign of metastasis

Abstract

Lymphomatouscellular infiltration of the greater omentum has been visualized by ultrasound as a uniformly thick, hyposonic, band-shaped structure adjacent to the anterior and lateral walls of the abdomen, following the contour of the abdominal convexity, and containing low-level, nonstructured internal echoes. From this finding, diffuse metastatic disease to the omentum can probably be inferred with a high degree of reliability.
