18 F-FDG PET/CT Findings of a Patient With Stercoral Colitis.

ABSTRACT: Stercoral colitis is a colonic inflammation caused by fecal impaction. It is now more commonly discussed in the literature due to its clinical significance, which has gained recognition in recent years. Delayed diagnosis may result in complications such as sepsis and perforation, which have a high mortality rate. Reporting incidentally detected stercoral colitis on FDG PET/CT can help prevent mortality and morbidity by enabling early diagnosis and treatment. In this case, we report on a patient with gastric cancer who was identified with stercoral colitis using FDG PET/CT data.

CT findings in idiopathic myointimal hyperplasia of mesenteric veins (IMHMV) and comparison to other colitides.

PURPOSE: The purpose of this study is to determine computed tomography (CT) findings that aid in differentiating idiopathic myointimal hyperplasia of mesenteric veins (IMHMV) from other colitides. METHODS: Retrospective review of histiologic proven cases of IMHMV (n = 12) with contrast enhanced CT (n = 11) and/or computed tomography angiography (CTA) (n = 9) exams. Control groups comprised of CT of infectious colitis (n = 13), CT of inflammatory bowel disease (IBD) (n = 12), and CTA of other colitides (n = 13). CT exams reviewed by 2 blinded gastrointestinal radiologists for maximum bowel wall thickness, enhancement pattern, decreased bowel wall enhancement, submucosal attenuation value, presence and location of IMV occlusion, peripheral mesenteric venous occlusion, dilated pericolonic veins, subjective IMA dilation, maximum IMA diameter, maximum peripheral IMA branch diameter, ascites, and mesenteric edema. Presence of early filling veins was an additional finding evaluated on CTA exams. RESULTS: Statistically significant CT findings of IMHMV compared to control groups included greater maximum bowel wall thickness, decreased bowel enhancement, IMV occlusion, and peripheral mesenteric venous occlusion (p < 0.05). Dilated pericolonic veins were seen more frequently in IMHMV compared to the infectious colitis group (64% versus 15%, p = 0.02). Additional statistically significant finding on CTA included early filling veins in IMHMV compared to the CTA control group (100% versus 46%, p = 0.008). CONCLUSION: IMHMV is a rare chronic non-thrombotic ischemia predominantly involving the rectosigmoid colon. CT features that may aid in differentiating IMHMV from other causes of left-sided colitis include marked bowel wall thickening with decreased enhancement, IMV and peripheral mesenteric venous occlusion or tapering, and early filling of dilated veins on CTA.

Idiopathic mesenteric phlebosclerotic colitis associated with Chinese herbal medicine

Idiopathic mesenteric phlebosclerotic colitis(IMP) is a rare disease. At present, the etiology and pathogenesis are not clear, but the main patients are Asian people, and most of them have a history of taking Chinese herbal medicines. The disease has characteristic endoscopic and imaging manifestations. This paper shares a case of IMP, The patient came to our hospital for one year because of intermittent abdominal pain and diarrhea. It conforms to the typical manifestations of IMP. For patients who take Chinese herbal medicine for a long time, if they have clinical manifestations of gastrointestinal tract, it is necessary to consider the possibility of the disease to avoid serious consequences due to missed diagnosis.

Tomografia computada de la apendicitis epiploica primaria aguda / Computed tomography of acute primary epiploic appendicitis

La apendicitis epiploica o también llamada apendagitis epiploica consiste en la inflamación de uno de los aproximadamente 100 apéndices epiploicos del colon, habiendo sido descripta tanto en el ascendente como en el descendente. Su conocimiento es important porque constituye una de las causas del abdomen agudo, cuya única sintomatología es el dolor ya que no cursa con alteración de la fórmula leucocitaria ni fiebre, pero de todas maneras el diagnóstico diferencial debe hacerse con otras causas como diverticulitis o apendicitis en primera instancia. La TC es categórica porque muestra la alteración de la densidad del espacio graso entre el colon y la pared abdominal, a diferencia de la apendicitis que se evidencia por dentro y detrás del colon, y sin mayor alteración de la pared colónica a diferencia de la diverticulitis. El tratamiento es conservador, estando indicados analgésicos en los casos de importante dolor. (AU)
