Coronary vein aneurysm presenting as pancreatic pseudocyst
Cardiovascular and Interventional Radiology
|January 1, 1985
Summary
Ultrasonography suggested a pancreatic pseudocyst, but surgery revealed a coronary vein aneurysm. Arteriography is crucial for diagnosing vascular anomalies before planned operations.
Area of Science:
- Cardiology
- Gastroenterology
- Diagnostic Imaging
Background:
- Pancreatic pseudocysts are fluid collections that can mimic other intra-abdominal pathologies.
- Vascular anomalies, such as aneurysms, can present with nonspecific symptoms.
- Ultrasonography is a common initial imaging modality for abdominal complaints.
Observation:
- A case initially suspected as a pancreatic pseudocyst based on ultrasonography findings.
- Intraoperative findings and subsequent arteriography revealed the true nature of the lesion.
Findings:
- The lesion was definitively identified as a coronary vein aneurysm, not a pancreatic pseudocyst.
- Ultrasonography demonstrated nonspecificity in differentiating vascular anomalies from neoplastic or cystic lesions.
Implications:
- Arteriography is essential for accurate diagnosis of vascular anomalies when surgery is contemplated.
- This case highlights the limitations of ultrasonography in characterizing certain vascular pathologies.
- Improved diagnostic accuracy for vascular anomalies can prevent unnecessary surgical interventions for misdiagnosed conditions.

01:27Acute Pancreatitis I: Introduction
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:24Chronic Pancreatitis I: Introduction
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:25Acute Pancreatitis I: Introduction
Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
