Abstract:
Mesenteric panniculitis (MP) is an inflammatory process of the mesenteric fat associated with a variable amount of fibrosis. We present the CT findings in four patients with MP. In three patients CT showed a fatty mass in the root of the mesentery and surrounding the mesenteric vessels without distorting them. The fourth patient presented an unusual form of MP with radiologically visible calcifications. Diagnosis was suggested preoperatively in two cases.
Insights
Mesenteric panniculitis (MP) is an inflammatory condition of the abdominal fat. CT scans reveal characteristic fatty masses and sometimes calcifications, aiding in preoperative diagnosis.
Area of Science:
- Radiology
- Gastroenterology
- Pathology
Background:
- Mesenteric panniculitis (MP) is a rare inflammatory condition affecting the mesenteric fat.
- It is characterized by inflammation and fibrosis of the mesentery.
- Understanding its imaging features is crucial for diagnosis.
Purpose of the Study:
- To describe the computed tomography (CT) findings in patients diagnosed with mesenteric panniculitis.
- To highlight the typical and atypical imaging presentations of MP.
Main Methods:
- Retrospective review of CT scans from four patients with confirmed mesenteric panniculitis.
- Analysis of imaging features, including location, morphology, and presence of calcifications.
Main Results:
- Three patients exhibited a fatty mass in the mesenteric root surrounding vessels without distortion.
- One patient presented an unusual form of MP with radiologically visible calcifications.
- Preoperative diagnosis was suggested in two of the four cases based on CT findings.
Conclusions:
- CT is valuable in diagnosing mesenteric panniculitis, showing characteristic fatty mesenteric masses.
- The presence of calcifications represents an atypical imaging feature of MP.
- Radiological findings can aid in preoperative diagnosis, guiding clinical management.
