Axial CT shows a cystic paraspinal mass adjacent to the esop | Figure 1

Cincinnati Children's Radiology

Axial CT shows a cystic paraspinal mass adjacent to the esophagus. The cystic appearance is typical of a foregut duplication cyst. In the chest, duplication cysts may be a bronchogenic cyst or an esophageal duplication cyst. It is not possible to distinguish between these entities on imaging. #FridayQuizDay

Coronal CT image of the pancreas shows multiple cysts (arrows) and small calcifications in the pancreas. Pancreatic cystosis is an uncommon finding of cystic fibrosis. Interestingly, the cysts in cystic fibrosis refer to pancreatic cystosis, NOT the cystic bronchiectasis that most people assume. Other pancreatic findings in cystic fibrosis include fatty replacement of the pancreas, pancreatic atrophy, acute or chronic pancreatitis, and pancreatic calcifications. #TummyTuesday

Coronal contrast-enhanced chest CT shows the rounded mass (arrow) of the left lower lobe. The mass has fluid attenuation with a thin enhancing rim and mild internal complexity. At resection, this was confirmed to be a bronchogenic cyst. Bronchogenic cysts are the most common type of foregut duplication cyst. They are usually asymptomatic and found incidentally. They are often resected due to the risk of infection and rarely, malignant degeneration. On the chest x-ray, the differential diagnosis includes round pneumonia and a duplication cyst. #FridayQuizDay #Quiz #FridayQuiz

Chest Ultrasound shows a 5cm oval hypoechoic cyst/mass with no internal blood flow.\nimage 4. Transverse view shows the mass in relation to the trachea\nimage 5. CT shows the lesion just above a 2 vessel Aorta\nFindings may be related to a collection of secretions via a leak. Another consideration may be an esophageal duplication cyst\nDiscussion: Enteric duplication cysts, are rare congenital malformations of the G.I. tract. They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the G.I. tract. Duplication cysts may also contain heterotopic tissue which can include -gastric mucosa -ectopic pancreatic tissue -lymphoid tissue -respiratory epithelium
