Inverted Meckel’S Diverticulum

Meckel’s diverticulum can manifest with various complications such as obstruction, intussusception, inflammation or diverticulitis, perforation, haemorrhage and fistula, and commonly manifests in children. Adult intussusception due to inverted Meckel’s diverticulum is an uncommon aetiology of intestinal obstruction but should be suspected in individuals. Imaging such as contrast-enhanced computed tomography aids in the diagnosis but it is not confirmatory to diagnose inverted Meckel’s diverticulum as a leading point. Resection of the intussusception segment is the definitive treatment. We present the case of a young man who presented in emergency with complaints of intestinal obstruction and ileo-ileal intussusception was the aetiology of for the same diagnosed on contrast-enhanced computed tomography of the abdomen. On exploration we discovered an inverted Meckel’s diverticulum to be the leading point for intussusception.

Inverted Meckel’S Diverticulum

Abstract Background Inverted Meckel’s diverticulum refers to the condition in which the diverticulum inverts on itself. The reasons for such an inversion are poorly understood due to the rarity of the condition. We present a case of inverted Meckel’s diverticulum, an uncommon finding, as a cause of recurrent intussusception. Case presentation A 30-year old Indian woman presented with complaints of pain in the central abdomen for 3 days, accompanied with vomiting and loose stools. Computed tomography images were suggestive of intussusception with intestinal obstruction. Intra-operative findings were suggestive of an intussuscepted segment of ileum measuring 10 cm in length, proximal to ileocecal junction. Ileo–ileal anastomosis was performed after appropriate resection. Upon opening the specimen, we were surprised to find an inverted Meckel diverticulum with lipoma at one end causing the intussusception. The patient made an uneventful recovery and was discharged after 5 days. Conclusion The reasons for inversion include abnormal peristalsis around the diverticulum and non-fixity of the diverticulum itself. The inverted diverticulum itself can cause luminal compromise and acts as a lead point for intussusception leading to obstruction. Computed tomography remains the diagnostic tool of choice for identifying intestinal obstruction and intussusception. Although pathological signs, such as lipoma, can be identified, the identification of any inversion will require a proficient radiologist. Inverted Meckel’s diverticulum is a rare condition which is difficult to diagnose preoperatively. Treatment is surgical, whether diagnosed pre-operatively or intra-operatively, and includes segmental resection and anastomosis. This uncommon condition should be noted as one-off differential diagnosis for intussusception and intestinal obstruction.

Abstract Funding Acknowledgements Type of funding sources: None. Background The natural history of thoracic aortic aneurysm (TAA) is one of progressive expansion. Asymptomatic patients who do not meet criteria for repair require conservative management including ongoing aneurysm surveillance, mostly carried out by contrast-enhanced computed tomography angiography (CTA). Purpose To prospectively compare image quality and reliability of a prototype non-contrast, self-navigated 3D whole-heart magnetic resonance angiography (MRA) with contrast-enhanced computed tomography angiography (CTA) for sizing of thoracic aortic aneurysm (TAA). Methods Self-navigated 3D whole-heart 1.5 T MRA was performed in 20 patients (aged 67 ± 8.6 years, 75% male) for sizing of TAA; a subgroup of 18 (90%) patients underwent additional contrast-enhanced CTA on the same day. Subjective image quality was scored according to a 4-point Likert scale and ratings between observers were compared by Cohen’s Kappa statistics. Continuous MRA and CTA measurements were analyzed with regression and Bland-Altman analysis. Results Overall subjective image quality as rated by two observers was 1 [interquartile range (IQR) 1-2] for self-navigated MRA and 1.5 [IQR 1-2] for CTA (p = 0.717). For MRA a perfect inter-observer agreement was found for presence of artefacts and subjective image sharpness (κ=1). Subjective signal inhomogeneity correlated highly with objectively quantified inhomogeneity of the blood pool signal (r = 0.78-0.824, all p <0.0001). Maximum diameters of TAA as measured by self-navigated MRA and CTA showed excellent correlation (r = 0.997, p < 0.0001) without significant inter-method bias (bias -0.0278, lower and upper limit of agreement -0.74 and 0.68, p = 0.749). Inter- and intraobserver correlation of aortic aneurysm as measured by MRA was excellent (r = 0.963 and 0.967, respectively) without significant bias (all p ≤ 0.05). Conclusion Self-navigated 3D whole-heart MRA enables reliable contrast- and radiation free aortic dilation surveillance without significant difference to standardized CTA while providing predictable acquisition time and by offering excellent image quality.
