Teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. Teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. We report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. A left-sided abdominal mass was detected on physical examination and B-Mod Ultrasound (US) examination revealed a heterogeneous mass with central cystic component. Computed tomography (CT) demonstrated a lobulated, heterogeneous, hypodense mass extending craniocaudally from the splenic hilum to the level of the left iliac fossa. Nephrectomy was performed and a large, fatty mass arising from the left kidney was excised. The final pathologic diagnosis was confirmed as cystic renal teratoma.
畸胎瘤是一种罕见的生殖细胞肿瘤，起源于一个或多个胚胎生殖细胞层。肾畸胎瘤极为罕见，迄今为止，原发性肾内畸胎瘤的病例报道不足30例。我们报告了一名两岁男孩左肾发生的一例不寻常的成熟囊性畸胎瘤的主要影像学特征。体格检查发现左侧腹部肿块，B超检查显示为一个具有中央囊性成分的不均匀肿块。计算机断层扫描（CT）显示一个分叶状、不均匀、低密度肿块，从脾门向头尾方向延伸至左髂窝水平。进行了肾切除术，切除了一个起源于左肾的巨大脂肪性肿块。最终病理诊断确认为囊性肾畸胎瘤。
