AIM:To determine the frequency and clinical impact of incidental findings detected with magnetic resonance imaging(MRI)-enterography in patients with suspected or known Crohn's disease(CD). METHODS:incidental findings were defined as unexpected lesions outside the small intestine,not previously known or suspected at the time of referral, and not related to inflammatory bowel disease.Through a systematic review of medical charts we analyzed the clinical impact of incidental findings,and compared the MRI findings with subsequent diagnostic procedures. RESULTS:A total of 283 patients were included in the analysis,and MRI detected active CD in 31%,fistula in 1.4%and abscess in 0.7%.Extra-intestinal findings notrelated to CD were recorded in 72 patients(25%),of which 58 patients(20%)had 74 previously unknown lesions.Important or incompletely characterized findings were detected in 17 patients(6.0%).incidental findings led to 12 further interventions in 9 patients(3.2%) revealing previously unknown pathological conditions in 5(1.8%).One patient(0.4%)underwent surgery and one patient was diagnosed with a malignant disease. MRI detected incidental colonic lesions in 16 patients of which additional work-up in 4 revealed normal anatomy. Two patients(0.7%)benefitted from the additional examinations,whereas incidental findings led to unnecessary examinations in 9(3.2%). CONCLUSION:In a minority of patients with suspected or known CD,important incidental findings are diagnosed at MRI-enterography.However,a substantial number of patients experience unnecessary morbidity because of additional examinations of benign or normal conditions.

Objective: To assess the importance of incidental extraspinal findings on Magnetic Resonance Imaging of the lumbar spine in two hospital facilities. Materials and Methods: It was a descriptive and retrospective study from November 2015 to March 2016. The records of patients who had done a Magnetic Resonance Imaging (MRI) scan of the lumbar spine were re-read in search of incidental findings. The incidental findings found were classified using Colonography Reporting and Data System(C-RADS) classification of extracolonic lesions to assess clinical significance. The prevalence of incidental findings was calculated for each facility, as well as the distribution according to age, the organs involved and the clinical importance. A non-detection rate was calculated by confronting the findings of the study with the original reports. Results: The prevalence of incidental findings was respectively 33% (19 out of 36) in Jordan Medical Center (JMC) in Yaounde and 27.74% (106 out of 292) in Jacques Monod Hospital. The extraspinal incidental findings were classified mainly as extracolonic 2 (E2): 58% in each facility. The percentage detection of incidental findings was 5% at JMS and 1.7% at Jacques Monod Hospital. Conclusion: Extraspinal incidental findings are frequent in both hospitals. However, the rate of detection remains very low.

Clues to predict incidental gallbladder cancer

引用

Hepatobiliary & Pancreatic Diseases International 2018年第2期17卷 149-154页

Background: Consequences of incidental gallbladder cancer(iGBC) following cholecystectomy may include repeat operation(depending on T stage) and worse survival(if bile spillage occurred), both avoidable if iGBC were suspected preoperatively.Methods: A retrospective single-institution review was done. Ultrasound images for cases and controls were blindly reviewed by a radiologist. Chi-square and Student’s t tests, as well as logistic regression and Kaplan–Meier analyses were used. A P ≤ 0.01 was considered significant.Results: Among 5796 cholecystectomies performed 2000–2013, 26(0.45%) were iGBC cases. These patients were older(75.61 versus 52.27 years), had more laparoscopic-to-open conversions(23.1% versus3.9%), underwent more imaging tests, had larger common bile duct diameter(7.13 versus 5.04 mm) and higher alkaline phosphatase. Ultrasound imaging showed that gallbladder wall thickening(GBWT) without pericholecystic fluid(PCCF), but not focal-versus-diffuse GBWT, was associated significantly with iGBC(73.9% versus 47.4%). On multivariable logistic regression analysis, GBWT without PCCF, and age were the strongest predictors of iGBC. The consequences iGBC depended significantly on intraoperative bile spillage, with nearly all such patients developing carcinomatosis and significantly worse survival.Conclusions: Besides age, GBWT, dilated common bile duct, and elevated alkaline phosphatase, number of preoperative imaging modalities and the presence of GBWT without PCCF are useful predictors of iGBC.Bile spillage causes poor survival in patients with iGBC.
