A 14-year-old girl presented with a large abdominal mass, thought to be an ovarian tumor on the basis of clinical and sonographic findings. MRI correctly suggested a primary colonic neoplasm. At operation, ovarian involvement was found to be secondary to metastatic signet ring cell adenocarcinoma of the colon, an extremely rare malignancy in this age group. Low index of suspicion for this tumor in children and adolescents results in advanced disease at diagnosis and poor prognosis. Early imaging with MRI is recommended when the nature of pelvic disease in children remains obscure.
一名14岁女孩因腹部出现巨大肿块就诊，根据临床及超声检查结果，最初考虑为卵巢肿瘤。磁共振成像（MRI）检查正确提示为原发性结肠肿瘤。手术中发现卵巢受累是结肠转移性印戒细胞腺癌所致，这在该年龄组极为罕见。儿童及青少年对此类肿瘤的怀疑指数较低，导致诊断时病情已属晚期，预后较差。当儿童盆腔疾病性质不明时，建议早期行MRI检查。
