The 4-week threshold for defining walled-off necrosis does not capture the dynamic process of encapsulation. We aim to investigate the changes in the wall characteristics of PFC in acute necrotizing pancreatitis (ANP) by comparing baseline contrast-enhanced computed tomography (CECT) with follow-up CT scans.\u0000 Methods This retrospective study comprised consecutive patients with ANP who underwent a baseline CECT within first 2 weeks and follow-up CECT in the third to fifth weeks of illness. Presence, extent, and encapsulation thickness (defined as enhancing wall around the collection) on baseline CECT were compared with follow-up CT (done in the third–fifth weeks of illness).\u0000 Results Thirty patients (19 males and 11 females; mean age 41.5 ± 13.5 years) were included in the study. The mean time to first CECT was 10 ± 3.6 days. There were 58 collections. The most common site was the lesser sac (n = 29), followed by the left pararenal space (n = 15). At baseline CT, 52 (89.7%) collections had varying degree of encapsulation (15.3%, complete encapsulation). Complete encapsulation was seen in 52 and 82.6% collections in third and fourth week, respectively. All collections in fifth week and beyond were encapsulated. The wall was thicker on follow-up CECT scans (p < 0.01). The mean wall thickness was not significantly associated with the degree of encapsulation (p = 0.417). There was no significant association between the site and degree of encapsulation (p = 0.546).\u0000 Conclusion Encapsulation is dynamic and collections may get “walled off” before 4 weeks. Walled-off collections should be defined based on imaging rather than a fixed 4-week revised Atlanta classification threshold.","PeriodicalId":506648,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141017401","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}

The more commonly known subtypes of HADD are calcific tendinopathy and calcific periarthritis. Carpal tunnel syndrome (CTS) can be rarely caused by calcific deposits within the carpal tunnel in the setting of HADD-related calcific periarthritis. Imaging, particularly ultrasound and radiographs, is crucial in distinguishing this entity from the conventional form of CTS that tends to be idiopathic. We describe a rare presentation of CTS secondary to calcific periarthritis in a 45-year-old patient, with imaging demonstrating mass-like calcification within the carpal tunnel, with typical features of those seen with HADD. The patient was treated with ultrasound-guided barbotage, with significant clinical improvement. The case highlights a lesser-known cause of CTS as well as a presentation of HADD, and the role of ultrasound-guided barbotage, a minimally invasive procedure, as a viable first-line management option as an alternative to surgery.","PeriodicalId":506648,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382941","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}

Joshi, Pareekshith R Rai, Yash Achhapalia","doi":"10.1055/s-0044-1778725","DOIUrl":"https://doi.org/10.1055/s-0044-1778725","url":null,"abstract":"\u0000 Background Glenoid version refers to the angle subtended by the glenoid with the scapula. On average, it is 0 ± 10 degrees with a slight propensity toward retroversion. Numerous factors such the dominance(handedness), gender, ethnicity, and pathology are known to affect version. Version has important consequences on the biomechanics of the shoulder joint and is altered in those with arthritis and shoulder joint instability.\u0000 Aim Our study aimed to determine the normal range of glenoid version in the population. Further, we aim to assess the relationship between gender and version.\u0000 Settings and Design We conducted a retrospective observational study in a tertiary referral hospital with a target sample size of 200 shoulders.\u0000 Methods and Materials The computed tomography images were retrospectively reviewed to determine the scapular shape and the glenoid version angle.\u0000 Statistical Analysis Statistical analysis was done using SPSS v.22 software with p-value less than 0.05 considered as significant.\u0000 Results The mean age of the individuals in our study was 44 years. In our study, irrespective of gender, most individuals had some degree of anteversion and males had lower degree of anteversion. Previous studies have shown that most normal individuals usually have retroverted shoulder joints. The mean glenoid version was significantly lower in the right than in the left shoulder and males had significantly lower mean glenoid version than females in both shoulders. Most individuals in our study had a flat scapular spine.\u0000 Conclusion This study shows that the Indian population may have a slight propensity toward anteversion and this has an important bearing on shoulder arthroplasty. Further, this study shows that significantly lower degrees of version are found on the right side and that the degree of version is significantly lower in males. Understanding the role of glenoid version in shoulder biomechanics will go a long way in the early identification of pathology, the preoperative planning of shoulder arthroplasty, and the operative restoration of a functional shoulder joint.","PeriodicalId":506648,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140471342","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}
