Presentation
Work up for hematuria. A left renal hypertrophied column of Bertin reported in the recent ultrasound evaluation.
Patient Data
A 43×33 mm mass is seen in the mid portion of the left kidney that shows a similar density to normal renal parenchyma on a non-enhanced CT scan. After IV contrast media injection, the attenuation value increased from 30 to 68 HU. A nephrographic phase CT scan shows that the mass enhances less than normal renal parenchyma.
A low attenuation hepatic lesion, measuring 35× 20 mm in diameter, is depicted, located at the 7th hepatic segment, revealing early peripheral, nodular enhancement and centripetal filling most consistent with a hemangioma.
The prostate gland is enlarged.
Case Discussion
The patient underwent a left renal mass resection, and the histopathology evaluation confirmed renal cell carcinoma, clear cell subtype.
The patient had a recent ultrasound report with a left renal hypertrophied column of Bertin. It should notice that the appearance hypertrophied column of Bertin on ultrasound can be confusing and the diagnosis can be confirmed with CT or MRI.
