The hypertrophied column of Bertin (HCB) is a benign anatomical variant of the renal cortex that may mimic a neoplastic mass, particularly on ultrasound, potentially leading to unnecessary diagnostic or surgical interventions. We report the case of a nine-year-old girl in whom a renal lesion was incidentally discovered during follow-up imaging for a post-traumatic subcapsular hematoma. Renal ultrasound revealed an isoechoic mass in the mid-portion of the left kidney, extending into the renal sinus. Color Doppler demonstrated a vascular pattern similar to the adjacent parenchyma. Contrast-enhanced computed tomography (CT) confirmed the diagnosis of HCB based on key imaging features, including homogeneity, isoattenuation relative to the renal cortex, and preservation of normal renal architecture. No signs of necrosis, distortion, or abnormal enhancement were observed. This case highlights the importance of recognizing the characteristic imaging features of HCB to prevent misdiagnosis and avoid unnecessary intervention. In asymptomatic patients, conservative management with imaging follow-up is an appropriate and safe approach.
贝尔廷柱状肥大（HCB）是肾皮质的一种良性解剖变异，可能会被误诊为肿瘤性肿块，尤其是在超声检查时，这可能会导致不必要的诊断或手术干预。我们报告了一例9岁女孩的病例，该女孩在因创伤后肾包膜下血肿进行随访成像时偶然发现了肾脏病变。肾脏超声显示左肾中部有一个等回声肿块，延伸至肾窦。彩色多普勒显示其血管形态与相邻肾实质相似。对比增强计算机断层扫描（CT）根据关键成像特征确诊为HCB，这些特征包括均匀性、相对于肾皮质的等密度以及正常肾结构的保留。未观察到坏死、变形或异常强化的迹象。该病例强调了识别HCB特征性成像特征以防止误诊和避免不必要干预的重要性。对于无症状患者，采用影像学随访的保守治疗是一种合适且安全的方法。
