Hypertrophic columns of bertin: imaging findings.

Hypertrophic column of Bertin (HCB) may mimic renal mass and may lead to unnecessary nephrectomy in some conditions. In this case report we present a patient with HCB, which mimics renal mass in ultrasonography (US) examination with its US, Doppler US and magnetic resonance imaging (MRI) findings. In contrast to the US, excretory urography (EU) and computed tomography (CT) findings of HCB, MRI findings of this entity could not take part in the literature sufficiently. We suggest that this case report could be useful in preventing the unnecessary biopsy and surgical procedures. In conclusion, however, US is often sufficient in the diagnosis of HCB, unusual lesions could be seen. In the final diagnosis of these lesions, MRI is very useful and more responsive technique. Understanding the imaging characteristics of HCB could prevent unnecessary interventional or surgical procedures.
