(a, b). Sonographic view of the right lower quadrant of the abdomen showing the interruption in the inferior margin of the spigelian fascia, the hernial defect is clearly visible (spotted line). Axial scan of the hernial sac, obtained in supine position, shows the “bulb-like” image determined by the presence of both the afferent and efferent loop (white arrows) tapered at the point of obstruction, the hyperechoic mesenteric and omental fat (*) and the inhomogeneous hypoechoic fluid collection (black arrow).
