Characteristics of ultrasound images and computed tomography in the diagnosis of cecal diverticulitis

Abstract

Objectives: Describe the characteristics of ultrasound images and computed tomography in the diagnosis of cecal diverticulitis.Subjects and methods: A cross-sectional study on 49 patients who underwent ultrasound and computed tomography at the Center of Radiology in Bach Mai Hospital, diagnosed with cecal diverticulitis on CT, was treated at Bach Mai Hospital from June 2020 to June 2021.Results: ultrasound showed diverticulum 63.3%, inside diverticulum there was fecal stone 18.3%, gas or fecal content 18.3%, fluid 26.5%, diverticulum wall thickness (>2mm) 28.6%, cecal wall thickness 95.9%, fat infiltration around the diverticulum or caecum 81.6%. 47/49 patients had thickened cecal wall, 89.8% thickened around the circumference. CT scan, 71.4% had 1 diverticulum, 20.4% had multiple diverticula, 10.2% had gas in the diverticulum, 55.1% had fecal stones, 26.5% had fluid in the diverticulum, thickened diverticulum (>2mm) 71.4%, 95.9% thickening of the cecum wall.Conclusions: Ultrasonography and CT imaging are very valuable imaging tools for determining the diagnosis, extent of lesions and complications of cecal diverticulitis, and are meaningful in clinical practice for choosing treatment methods.
