Objectives Crohn’s disease (CD) is a condition that can occur in any part of the gastrointestinal tract, although usually forms in the colon and terminal ileum. Magnetic resonance imaging (MRI) has become a beneficial modality in the evaluation of small bowel activity. This study reports on a systematic review and meta-analysis of magnetic resonance enterography for the prediction of CD activity and evaluation of outcomes and possible complications. Methods Following the PRISMA guidelines, a total of 25 low-risk studies on established CD were selected, based on a QUADAS-II score of ≥ 9. Results A sensitivity of 90% was revealed in a pooled analysis of the 19 studies, with heterogeneity of χ2 = 81.83 and I2 of 80.3%. Also, a specificity of 89% was calculated, with heterogeneity of χ2 = 65.12 and I2 of 70.0%. Conclusion It was concluded that MRI provides an effective alternative to CT enterography in the detection of small bowel activity in CD patients under supervision of radiologist for assessment of disease activity and its complications. Its advantages include the avoidance of radiation exposure and good diagnostic accuracy.

Introduction: Acute appendicitis is a known surgical emergency. It is rare for port site hernia to contain incarcerated inflamed appendix. Case presentation: We describe a distinctive case of incarcerated appendicitis in port-site hernia following laparoscopic cholecystectomy. Acute appendicitis was pre-operatively CT diagnosed and appendectomy was performed followed by primary repair of the hernia defect. Awareness of atypical presentation and possible complications may raise the clinical suspicion index to ask for early CT.

Objectives: To assess the frequency of ageing-related lung changes seen on computed tomography (CT) chest examinations performed on teleradiology cohort of elderly patients. Materials and Methods: An experienced radiologist retrospectively assessed at a 3-month worth of teleradiology data of CT chest, abdomen and pelvis performed for detection or staging of malignancy is in asymptomatic patients 60 years old and older, residing in Saudi Arabia. Patients with known smoking history or obscuring abnormalities were excluded. Lung windows were analyzed to detect bronchial wall thickening, mosaic attenuation, linear scars, reticulations and pneumatocoeles. Bronchial thickening and mosaic attenuation were stratified by severity, while the scars and pneumatocoeles were stratified by number. Results: A total of 26 cases were collected out of 137 patients, with a mean age of 67 years old (61% males). Bronchial wall thickening was detected and 56%, with 35% being of moderate degree. Mosaic attenuation was detected in 26%, with 70% being of mild degree. Linear scarring was seen and 61%, in the absence of reticulations. Pneumatocoeles were detected in 26%, with 22% being more than 2 in numbers. Conclusion: In a select teleradiology cohort of asymptomatic CT chest imaging in elderly patients, bronchial wall thickening, mosaic attenuation, linear scarring pneumatocoeles are frequently encountered. Such findings should not lead to clinical or imaging misinterpretations.
