Summary
Perivascular epithelioid cell tumors (PEComas) of the pancreas are rare. This case report details imaging findings of a pancreatic PEComa, offering valuable insights for diagnosis.
Area of Science:
- Oncology
- Gastroenterology
- Radiology
Background:
- Pancreatic perivascular epithelioid cell tumors (PEComas) are exceptionally rare neoplasms.
- Previous literature has documented only a few cases of pancreatic PEComas.
Observation:
- A 60-year-old female presented with a palpable right upper quadrant mass.
- Multidetector-row CT revealed a 3.5 cm hypovascular, encapsulated pancreatic body tumor.
- Endoscopic ultrasound showed a heterogeneous, mixed hypo- and hyper-echoic pancreatic mass.
Findings:
- This report presents the first detailed multidetector-row CT and endoscopic ultrasound features of a pancreatic PEComa.
- The imaging characteristics aid in differentiating PEComas from other pancreatic tumors.
Implications:
- Accurate radiological characterization is crucial for the diagnosis of rare pancreatic tumors like PEComas.
- Enhanced understanding of PEComa imaging may improve early detection and patient management.
- This case contributes to the limited radiological literature on pancreatic PEComas.
