“…This thickening consists of two layers: a thick echogenic inner layer of redundant mucosa stemming from edema and pseudomembranous formation, and an outer hypoechoic layer corresponding to the muscularis propria ( Fig. 8 ) [ 10 ]. Ischemic colitis generally affects the left colon and causes segmental wall thickening.…”

Lower abdominal pain is frequently reported and has a diverse differential diagnosis. In cases with atypical presentation and nonspecific findings, further imaging evaluation is required to confirm the clinical suspicion and to distinguish between self-limiting disorders and those requiring immediate intervention. In line with European guidelines, transabdominal ultrasonography is recommended as a first-line imaging modality for clinically suspected acute appendicitis and acute diverticulitis, which respectively represent the predominant causes of right and left lower quadrant abdominal pain. It is similarly the preferred method for evaluating suspected obstetric/gynecologic and genitourinary diseases. Computed tomography is utilized as a secondary option when ultrasonography results are inconclusive. This pictorial essay illustrates the sonographic features of the most common conditions associated with lower abdominal pain and outlines the clinical characteristics of each entity.

Clostridium difficile colitis is diagnosed using an immunoassay or polymerase chain reaction (PCR) assay for toxins A/B. Since ultrasound is frequently used as a screening test for hospitalized patients suffering from different abdominal morbidities, we searched for sonographic indicators of C. difficile infection (CDI). In a prospective and blinded case-control study, abdominal ultrasound was performed on hospitalized patients for whom stool samples were sent for C. difficile toxin immunoassay. All patients with positive toxin were included as the case group and patients with negative toxin comprised the control group. Sonographic parameters of both groups were compared. Demographic variables of the 67 patients in the toxin-positive group were similar to those of the 71 patients in the toxin-negative group. The sonographic parameters which were found to be associated with CDI included colonic wall thickening, appearing in 61 (91%) patients of the toxin-positive group versus 15 (21%) patients of the toxin-negative group (p < 0.001), and also internal ring (24 versus 0%, p < 0.001), external ring (15 versus 0%, p < 0.001), ascites (24 versus 10%, p < 0.001), and diminution of large bowel content (16 versus 1%, p < 0.001). Bowel wall thickening had high positive and negative predictive values (0.80 and 0.90, respectively), while the other features had only high positive predictive values (0.7-1.0). Abdominal ultrasound may contribute to the diagnosis of C. difficile colitis in patients developing hospital-acquired diarrhea.
