Ultrasound in the diagnosis of abdominal abscesses

Cecal Necrosis Due to Ischemic Colitis Mimicking an Abscess on Sonography

“…Abdominal sonography revealed a large mass and a small amount of ascites at the ileocecal region. This tumor was composed of hypoechoic and hyperechoic portions, a finding that was consistent with that of an abscess ( Figure 1A), 9 and it was visualized as a heterogeneous intensity mass by computed tomography ( Figure 1B). On the basis of the results of these examinations, a diagnosis of septic shock due to an ileocecal abscess secondary to appendicitis or diverticulitis was made, and then a laparotomy was performed.…”

Noninvasive Diagnosis of Small Bowel Crohnʼs Disease: Combined Use of Bowel Sonography and Tc-99M-Hmpao Leukocyte Scintigraphy

“…Entero‐cutaneous, entero‐enteric, and entero‐mesenteric fistulas were considered present when hypoechoic duct‐like structures with fluid or air content were seen between skin and intestinal loops, between two intestinal loops, or between intestinal loop and mesentery, respectively 34. The presence of abscesses was evaluated according to the current literature 35. In case of diagnosis of CD, the gastroenterologist would describe the exact location and extension of the disease.…”
