Brunner gland hyperplasia, a rare duodenal tumor, can present with high F-FDG avidity on PET/CT scans. This finding suggests it should be considered in the differential diagnosis of duodenal masses.
Area of Science:
- Gastroenterology
- Oncology
- Radiology
Background:
- Brunner gland hyperplasia is a rare duodenal tumor typically exhibiting benign characteristics.
- Differential diagnosis of duodenal masses can be challenging.
Observation:
- A 68-year-old male patient with anemia presented with a polypoid duodenal mass.
- Imaging via CT and esophagogastroduodenoscopy revealed the mass.
- Positron Emission Tomography/Computed Tomography (PET/CT) demonstrated high Fluorodeoxyglucose (F-FDG) avidity in the mass.
Findings:
- Histopathological examination confirmed the duodenal mass as Brunner gland hyperplasia.
- The mass exhibited significant F-FDG uptake, a characteristic often associated with malignancy.
Implications:
- Brunner gland hyperplasia should be included in the differential diagnosis for F-FDG-avid duodenal tumors.
- This case highlights the importance of integrating imaging findings with histopathology for accurate diagnosis.
