A 3-year-old male presents to the ED with two days of abdominal pain, cramping, anorexia, bilious emesis, RLQ tenderness on exam, and leukocytosis on CBC, refractory to trial of antiemetics, antipyretics, IV fluids, and analgesics. RLQ US and KUB showed an obstructive pattern. MRI demonstrated an inflamed RLQ fluid signal structure, suggesting appendicitis. CT identified a normal appendix and localized a RLQ transition point confirming high-grade SBO. After a trial of bowel rest, a repeat KUB revealed progression. Laparoscopy visualized a RLQ transition point coinciding with a twisted ileum segment due to a Meckel's diverticulum leadpoint. Segmental bowel resection and ileoileal anastomosis was performed. Hemorrhagic necrosis of a true diverticulum was confirmed histologically.
Meckel's is a common congenital GI anomaly, a vestigial structure from the embryologic omphalomesenteric duct. It has a prevalence of 2% and the complication rate is 6%, to include SBO such as in this case. Presentation is typically in the first 2 years of life. Meckel’s are true diverticula which have mucosal, muscularis, and serosal elements, unlike pseudodiverticula. The presence or absence of a muscularis propria layer cannot be determined on imaging alone, yet is evident on histology. Pseudodiverticula, which are more common along the mesenteric side, can originate anywhere in the GI tract.
Meckel's diverticulum has a narrow imaging differential. The appendix is another true diverticula in the right lower quadrant, although Meckel's originates from the distal ileum rather than the cecum. Diverticulosis often presents later with multiple pseudodiverticula in the left hemicolon. Enteric duplication cysts are another, albeit less common, fluid-filled formation located close to the colon. In contradistinction, communication with the intestinal lumen is unusual.
When a single diagnosis cannot be made and surgery is not warranted, a probabilistic presumptive diagnosis is often used in the absence of histology, particularly in cases where management is the same. Asymptomatic Meckel's diverticulum cases don't require treatment. In complicated yet stable patients, expectant management can be employed. If symptoms progress, surgical management may be needed for diagnosis and treatment.
This case highlights the essential role of imaging along with clinical context to differentiate Meckel's diverticulum from similar entities, in order to guide management. Read More

Meckel’s diverticulum is the most common congenital anomaly of the GI tract, with an occurrence rate of 2% in the general population. It is a true diverticulum caused from the persistence of the omphalomesenteric duct after the 6-8th week of gestation.

Although it is usually asymptomatic, there is a lifetime 4% risk for complications in patients up to the age of 20, with complication rates being higher in males than females. Among the possible complications are hemorrhage, intestinal obstruction, diverticulitis, perforation, and neoplasia. Knowledge of the radiological/clinical manifestation of a patient with Meckel’s diverticulum and its complications is of great importance for the radiologist as it can mimic other pathologies making its diagnosis a challenging one.

The purpose of this educational poster is to review and illustrate some of the imaging/clinical manifestations of some of the complications of Meckel’s diverticulum based on our experience at our hospital. Read More

Meckel’s diverticulum is the most common congenital gastrointestinal tract abnormality, with a small minority of patients presenting with symptoms related to complications. The aim of this educational exhibit is to provide a pictorial overview of the common and uncommon imaging manifestations of symptomatic Meckel’s diverticulum, with an emphasis on CT findings, though scintigraphic, sonographic, radiographic, and fluoroscopic features will also be detailed.

Meckel’s diverticulum is the most common congenital anomaly involving the omphalomesenteric duct. While patients may be asymptomatic, the clinical manifestations of Meckel’s diverticulum can be nonspecific, and the entity may be discovered only after the onset of complications. The purpose of this exhibit is to characterize the imaging manifestations of the different omphalomesenteric duct anomalies, with a focus on Meckel’s diverticulum, and describe their complications.

Calyceal diverticula (CD) are rare lesions which are difficult to differentiate from renal cysts. Cross sectional examination with excretory imaging facilitates diagnosis in a noninvasive fashion. Functional MR urography (fMRU) provides comprehensive morphological, functional and excretory assessment of the kidney with CD. We aim to describe the findings of CD in fMRU. Read More
