Clinical Report: Imaging Characteristics of Brenner Tumors
Overview
This study investigates the imaging features of ovarian Brenner tumors (BTs) to enhance differential diagnosis between benign and malignant variants. Key findings indicate that maximum tumor diameter, presence of papillary projections, and venous-phase CT net enhancement are significant markers for distinguishing between these subtypes.
Background
Ovarian Brenner tumors are rare neoplasms that account for a small percentage of ovarian tumors, with benign forms having a favorable prognosis. Accurate preoperative differentiation between benign and malignant variants is crucial for treatment planning and patient outcomes, as malignant BTs are aggressive and associated with poor prognosis. However, existing literature on their imaging characteristics is limited, necessitating further investigation.
Data Highlights
Characteristic
Benign BTs
Borderline/Malignant BTs
Serum CA125 Levels
Lower
Higher (p < 0.05)
Maximum Tumor Diameter
Smaller
Larger (p < 0.05)
Presence of Papillary Projections
Less Common
More Common (p < 0.05)
Venous-phase CT Net Enhancement
Lower
Higher (p < 0.05)
Key Findings
Elevated serum CA125 levels are significantly more common in borderline/malignant BTs (p < 0.05).
Maximum tumor diameter is a critical differentiating factor, with malignant tumors being larger.
Presence of papillary projections is more frequent in borderline/malignant BTs.
Venous-phase CT net enhancement serves as an independent risk factor for malignancy.
The combined model for risk assessment showed an AUC of 0.956, indicating high discriminative ability.
Clinical Implications
Clinicians should consider maximum tumor diameter, papillary projections, and venous-phase CT net enhancement when assessing ovarian Brenner tumors preoperatively. These imaging characteristics can significantly aid in differentiating between benign and malignant variants, thereby informing treatment strategies and improving patient management.
Conclusion
The study highlights the importance of specific imaging features in the differential diagnosis of ovarian Brenner tumors. Enhanced preoperative assessment can lead to better clinical outcomes through appropriate treatment planning.
