Abstract:
Mesenteric panniculitis (MP) is a rare condition that encompasses a spectrum of disease processes characterized by degeneration, inflammation, and scarring of the adipose tissue of the mesentery. The etiology of MP remains unknown; although various causes have been suggested and it has been seen to occur independently as well as in association with other disorders. The clinical manifestations of MP vary over a spectrum, and most patients actually experience no discomfort at all. When present, these clinical presentations vary according to the stage of the disease and may include general symptoms like abdominal pain and weight loss or more specific ones such as an abdominal mass, peritoneal irritation, and ascites. CT findings have emerged to be the gold standard in diagnosis, wherein MP is characterized by localized mesenteric thickening and stranding covering the blood vessels with a characteristic 'halo sign', in which the fat around the lymph nodes and blood vessels is spared. Here, we present the case of a 45-year-old male patient who reported to a private hospital in Karachi, Pakistan with non-specific complaints of abdominal pain and vomiting and typical CT and histopathology findings of MP on investigation, as well as abnormally raised alanine transaminase (ALT) levels.
Insights
Mesenteric panniculitis (MP) is a rare inflammatory condition affecting abdominal fat. This case highlights typical CT and histopathology findings in a patient presenting with abdominal pain and vomiting.
Area of Science:
- Gastroenterology
- Radiology
- Pathology
Background:
- Mesenteric panniculitis (MP) is a rare idiopathic condition involving inflammation and fibrosis of mesenteric adipose tissue.
- Its etiology is unknown, with potential associations with other disorders.
- Clinical presentation varies, often asymptomatic, but can include abdominal pain, weight loss, and ascites.
Observation:
- A 45-year-old male presented with abdominal pain and vomiting.
- Computed tomography (CT) revealed characteristic findings of MP, including mesenteric thickening, stranding, and a 'halo sign'.
- Histopathology confirmed the diagnosis, and elevated alanine transaminase (ALT) levels were noted.
Findings:
- CT imaging is crucial for diagnosing MP, showing specific patterns of mesenteric fat involvement.
- Histopathology provides definitive diagnosis.
- The case demonstrates a typical presentation of MP with associated elevated ALT levels.
Implications:
- This case underscores the importance of recognizing characteristic CT findings for early MP diagnosis.
- Understanding MP's varied presentations aids in clinical management.
- Further research into MP etiology and associations is warranted.

Acute Pancreatitis I: Introduction
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:

Chronic Pancreatitis I: Introduction
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...
