Proteus Syndrome (PS) is a rare congenital disease marked by a broad spectrum of congenital malformation. We present a case of an eight-year-old boy who was previously diagnosed with PS and started with 1 week of gross hematuria with no other symptoms. During the investigation, CT scan and MRI were performed showing some nodular (polypoid) lesions up to 1 cm in the bladder wall with diffusion restriction, contrast gain and no signs of invasion. Cystoscopy was done and the vascular malformations were fulgurated with Ho:Yag laser. After an eighteen-month follow-up, he had no new episodes of hematuria.
变形综合征（PS）是一种罕见的先天性疾病，其特征为广泛的先天性畸形。我们报告一例8岁男孩，此前被诊断为PS，开始出现1周的肉眼血尿，无其他症状。在检查过程中，进行了CT扫描和MRI检查，结果显示膀胱壁有一些最大直径达1厘米的结节状（息肉样）病变，有弥散受限、造影剂增强且无浸润迹象。进行了膀胱镜检查，并用钬激光对血管畸形进行了电凝治疗。经过18个月的随访，他没有出现新的血尿发作。
