Pericardial Lipoma With Fat Necrosis

Area of Science:

• Cardiovascular Pathology
• Surgical Oncology
• Diagnostic Imaging

Background:

• Pericardial lipomas are rare, benign cardiac tumors originating from adipose tissue.
• Fat necrosis is an uncommon condition characterized by cellular death in adipose tissue.
• The coexistence of pericardial lipoma and fat necrosis is exceptionally rare in medical literature.

Purpose of the Study:

• To report the first documented case of a pericardial lipoma with concurrent fat necrosis.
• To describe the clinical and imaging characteristics of this rare condition.
• To discuss the diagnostic challenges posed by its presentation mimicking a malignant tumor.

Main Methods:

• Case report detailing a patient with a pericardial mass.
• Review of clinical presentation, imaging studies (e.g., CT, MRI), and histopathological findings.
• Correlation of imaging features with definitive histopathology.

Main Results:

• The patient presented with symptoms suggestive of a malignant cardiac tumor.
• Imaging studies were consistent with a benign pericardial lipoma.
• Histopathological examination confirmed a pericardial lipoma with areas of fat necrosis.

Conclusions:

• This case highlights the potential for benign pericardial lipomas with fat necrosis to present with malignant-like clinical features.
• Accurate diagnosis requires careful integration of clinical, imaging, and histopathological data.
• This rare entity underscores the importance of comprehensive evaluation in cardiac mass diagnosis.
