Coronary artery fistulas are anomalous terminations of the coronary arteries. Most often, these fistulas are incidentally identified in the adult and pediatric populations. Many patients are asymptomatic; however, an awareness of these fistulas is important because they have been associated with various clinical features, including chest pain or heart failure in young patients. Correct diagnosis of coronary artery fistulas is important, and early surgical correction is indicated because of the high prevalence of late symptoms and complications. Traditionally, conventional angiography has been used for the diagnosis of coronary anomalies. With more frequent use of 64-row multi-detector computed tomography (CT) in chest and cardiac imaging, the number of incidentally found coronary artery fistulas has been increasing. CT angiography and conventional angiography can have additive value in diagnosis of this cardiac anomaly. In every CT study of the heart, special attention should be paid to the courses and terminations of the coronary arteries to detect these potentially fatal anomalies.

We report a case of gastric emphysema following placement of nasogastric (NG) tube. Gas in the wall of the stomach is a rare finding seen in various clinical situations. The reported cases fall into two different categories: "gastric emphysema" and "emphysematous gastritis". Differentiating these two entities is important, as the first one is usually a benign condition, but the second one carries a poor prognosis.

Jejunogastric intussusception (JGI) is a rare but potentially lethal complication of gastrectomy or gastrojejunostomy. In the acute setting, early diagnosis and prompt surgical intervention are mandatory to avoid mortality. We present a case of JGI in a patient with a history of gastrojejunostomy who had increasing vomiting, hematemesis, and abdominal pain for 1 day.

Colonoscopy is a commonly used diagnostic and therapeutic procedure. Splenic injury or rupture after this procedure is rare. We report a case of splenic rupture and hematoma in a middle-aged man who presented with symptoms of worsened anemia after diagnostic colonoscopy.
