Article Synopsis
- A study was conducted to analyze the clinical and radiological characteristics of patients with suspected pancreatic acinar cystic transformation (ACT) based on available imaging data from 2003 to 2021.
- Of the 64 patients included, 53% were classified as having "certain" ACT, while 47% were "uncertain," with no significant difference in the number of imaging criteria between these groups.
- The findings indicate that the existing imaging criteria for diagnosing ACT often overlap with other conditions, suggesting that these criteria may be inadequate for making definitive diagnoses in some patients.
Pancreatic acinar cystic transformation (ACT) is a recently described entity of the pancreatic cysts' spectrum. It is a nonneoplastic pancreatic lesion, mostly asymptomatic, and is considered a rare disease, with less than 100 reported cases. Its benign nature and the absence of reported cases of malignant transformation or invasive lesions were a plea for a conservative approach.

- - Multiple chronic ulcers in the small intestine are often linked to Crohn's disease, but can also arise from issues related to abnormal prostaglandin activation or specific genetic mutations (like in the SLCO2A1 gene) affecting enteropathy.
- - A case involving two French sisters highlighted the identification of chronic enteropathy associated with SLCO2A1 (CEAS), revealing that this syndrome is not limited to Asian populations, as previously believed.
- - Genetic testing confirmed both sisters shared mutations in the SLCO2A1 gene, prompting the need for more awareness and genetic screening for this condition in European patients with recurrent intestinal issues resembling Crohn's disease.
Background: MRI is the reference for the diagnosis of arterial cerebral ischemia, but its role in acute mesenteric ischemia (AMI) is poorly known.
Purpose: To assess MRI detection of early ischemic bowel lesions in a porcine model of arterial AMI.
Study Type: Prospective/cohort.
Objectives: This study aimed to investigate the prevalence, risk factors, and outcomes of colonic involvement in patients with acute mesenteric ischemia (AMI).
Methods: CT scans from a prospective cohort of 114 AMI patients treated in an intestinal stroke center between 2009 and 2018 were blindly reviewed by two radiologists. Colon involvement was defined on CT scan by the presence of at least one of the following CT colonic features: wall thickening, pneumatosis, decreased wall enhancement, dilatation, or perforation.
Purpose: The purpose of this study was to compare the value of contrast-enhanced computed tomography (CT) to that of magnetic resonance imaging obtained with extracellular contrast agent (ECA-MRI) for the diagnosis of a tumor capsule in hepatocellular carcinoma (HCC) using histopathologic findings as the standard of reference.
Materials And Methods: This retrospective study included patients with pathologically-proven resected HCCs with available preoperative contrast-enhanced CT and ECA-MRI examinations. Two blinded radiologists independently reviewed contrast-enhanced CT and ECA-MRI examinations to assess the presence of an enhancing capsule.
Background: Teduglutide (TED) is a glucagon-like peptide 2 analogue approved in patients with short bowel syndrome with chronic intestinal failure. Bowel epithelial hyperplasia has been reported after TED treatment.
Objective: The aim of this study was to describe small bowel modifications at imaging in patients with SBS-CIF receiving TED and to assess their predictive value for clinical response.
