幼年颗粒细胞瘤(GCT)是儿童罕见的卵巢肿瘤,影像学表现为多部位囊型和不规则壁增厚,浆液性囊腺瘤(SCA)也是儿童中另一种罕见的良性囊性卵巢肿瘤。儿童两侧出现两种罕见类型的卵巢肿瘤极为罕见。我们报告了一名4岁女性,表现出性早熟症状,并在手术切除后诊断为左侧卵巢患有青少年GCT。然而,在GCT切除后1年的随访中,她在右卵巢出现了另一个多部位囊性肿块,并在手术切除和组织病理学评估后诊断为SCA。主要GCT切除后的囊性卵巢肿瘤的出现需要区分主要GCT和其他囊性卵巢肿瘤的复发,尽管这种情况非常罕见。此外,影像学特征对良恶性卵巢肿瘤的鉴别诊断具有重要意义。
Juvenile granulosa cell tumor (GCT) is a rare ovarian tumor in children, presenting with a multiloculated cystic pattern and irregular wall-thickening on imaging and serous cystadenoma (SCA) is also another rare benign cystic ovarian tumor in children. The appearance of two uncommon types of ovarian tumors on both sides in children is extremely rare. We report the
case of a 4-year-old female presenting with symptoms of precocious puberty and diagnosed with juvenile GCT on the left ovary after surgical resection. However, during follow-up 1 year after GCT resection, she presented with another multiloculated cystic mass in the right ovary, and diagnosed as SCA after surgical resection and histopathologic evaluations. The appearance of cystic ovarian tumor after primarily GCT resection need to differentiate between the recurrence of the primarily GCT and other cystic ovarian tumors although it is very uncommon. Furthermore, the imaging features played a key role in the differential diagnosis between benign and malignant ovarian tumors.
