Overwhelming majority of patients with acute appendicitis abscess form can not get the full longitudinal – process, is determined only by a fragment in the transverse or longitudinal section. OD phlegmonous modified appendix ranges from 6.5 to 11.5 mm and is not dependent on the age of the patient.
It should be noted that the outer diameter dimension, which is an important diagnostic of inflammatory transformation be carried out at a cross section available vizualization most fragment modified process. In all cases it is possible to detect a significant thickening of the wall layers visible appendix. Thickness of the inner hyperechogenic rim (displaying the mucous layer) reaches 3 mm, medium hypoechoic rim (displaying the submucosal and muscular layers) – 2-3 mm, the outer rim (serosa) – 2-2.5 mm. Reliable echographic signs compromising the integrity of the wall layers of the appendix in patients with this form of inflammation is not detected. Appendiceal lumen extends from 3 to 6 mm, it is filled with heterogeneous content.
In some cases, defined as structures coprolites irregular round shape with different diameters and different echogenicity, as well as fine particles, which are strands of fibrin.
