Enteric duplication cysts, sometimes simply called duplication cysts, are rare congenital malformations of the gastrointestinal tract. [1] They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the gastrointestinal tract. [1] They may be cystic or tubular in conformation. [2]
Bronchogenic cysts are usually found in the middle mediastinum. Chest x-rays show a smooth density just in front of the trachea or main stem bronchi at the carinal level. When the cyst communicates with the tracheobronchial tree, the air-fluid level may be seen within the cyst. CT scanning is useful in localizing these cysts.
The foregut in humans is the anterior part of the alimentary canal, from the distal esophagus to the first half of the duodenum, at the entrance of the bile duct. Beyond the stomach, the foregut is attached to the abdominal walls by mesentery .
Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
Pericardial cysts have an incidence of 1 in 100,000. [2] [7] Pericardial cysts make up 6-7% of all mediastinal masses. [2] [3] They can present at any age, but are most commonly diagnosed between the third and fifth decade of life. [2] [3] Females and males have approximately equal incidences of pericardial cysts.

A Meckel's diverticulum, a true congenital diverticulum, is a slight bulge in the small intestine present at birth and a vestigial remnant of the vitelline duct.It is the most common malformation of the gastrointestinal tract and is present in approximately 2% of the population, [1] with males more frequently experiencing symptoms.
Enteric duplication cyst; Giardiasis; Pancreatitis; Peptic ulcer disease; Yellow fever; Helicobacter pylori is a gram-negative spiral bacterium. Over half the world's population is infected with it, mainly during childhood; it is not certain how the disease is transmitted. It colonizes the gastrointestinal system, predominantly the stomach.
Pain can occur with mediastinitis but the location of the pain depends on which part of the mediastinum is involved. When the upper mediastinum is involved, the pain is typically retro-sternal pain. When the lower mediastinum is involved, pain can be located between in the scapulae and radiate around to the chest. [2]
