Cross-sectional imaging and lymphoscintigraphy have historically dominated assessment, while transabdominal B-mode intestinal ultrasound (IUS)-a cornerstone modality for inflammatory bowel disease-has remained almost unmapped in PIL. We conducted a PRISMA-ScR scoping review (Open Science Framework preregistration gfbc9) of all primary studies reporting transabdominal B-mode IUS in PIL, searching three bibliographic platforms (PubMed/MEDLINE, Ovid Multifile, Scopus) supplemented by forward and backward citation chasing. Studies using only extra-intestinal ultrasound, endoscopic ultrasound, those describing secondary lymphangiectasia or focal lymphangioma, and those using ultrasound only as procedural guidance for lymphangiography were excluded at full-text stage. Fifteen primary studies, published 1986-2026 across thirteen countries, met eligibility (nine paediatric, six adult). All fifteen reported per-patient B-mode IUS findings extractable for synthesis. A consistent sonographic signature emerged: diffuse, regular, slightly hypoechoic small-bowel-wall thickening with preserved five-layer stratification and prominent valvulae conniventes; dilated fluid-filled loops with reduced peristalsis; oedematous mesentery, variable ascites; and characteristically absent mesenteric lymphadenopathy (with two notable exceptions framed only as a research hypothesis). Diagnostic accuracy as a screening tool has been evaluated only in one study (n = 20: accuracy 80%, 95% CI 56.3-94.3%).

We report a case of low-grade appendiceal mucinous neoplasm (LAMN) in which a tadpole-shaped appendiceal lesion acted as the leading point of extensive intestinal intussusception. A woman in her 60s presented with abdominal pain and difficulty with defecation. Abdominal ultrasonography demonstrated extensive intestinal intussusception extending to the transverse colon. At the leading point, the long-axis view showed a tadpole-shaped configuration composed of a spherical cystic dilated portion and a contiguous tubular structure. Dynamic observation suggested that these findings represented a single continuous appendiceal structure rather than separate cystic lesions. The short-axis view of the same structure showed a multilayered concentric ring appearance. Surgical and histopathologic examination established the diagnosis of appendiceal intussusception associated with LAMN, with secondary intestinal intussusception. Although prior or serial imaging was not available to directly demonstrate temporal progression from appendiceal to intestinal intussusception, previous reports have described appendiceal mucinous lesions with tadpole-shaped or cup-and-ball morphology as the leading point of intussusception. Therefore, when this morphology is identified on ultrasonography, careful assessment for appendiceal or intestinal intussusception is warranted. Recognition of this morphology and its continuity on ultrasonography may serve as a practical diagnostic clue and contribute to preoperative diagnosis and appropriate surgical management.</p>","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148609979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In respiratory medicine, its application is increasingly explored for pleural and subpleural lesions, pleural effusions, and pneumothorax. This narrative review examines current evidence for thoracic ultrasound elastography, highlighting potential benefits and key limitations. Several studies suggest that elastography can differentiate malignant from benign pleural lesions and show superior sensitivity for elastography-guided versus traditional ultrasound-guided pleural biopsy. However, significant challenges hinder clinical implementation: lack of standardised protocols, variability across ultrasound systems, operator dependency, and limited multicentre validation. The \"elasto-lung point\" sign has been described as potentially useful for pneumothorax detection, but its incremental value beyond conventional ultrasound remains uncertain and requires further investigation. Elastography has also been preliminarily studied for non-expandable lung detection, although current evidence suggests that M-mode ultrasound may perform better. Integration with artificial intelligence holds promise to enhance future diagnostic capabilities. Overall, thoracic elastography represents an innovative approach that requires substantial validation before routine clinical use can be recommended. Future priorities include protocol standardisation, rigorous multicentre studies, and demonstration of impact on patient outcomes.</p>","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148581001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
