Ovarian Dysgerminoma Demonstrated by FDG PET/CT
卵巢惡性胚胎瘤在氟-18去氧葡萄糖正子電腦斷層造影上的表現
摘要
Dysgerminomas are rare ovarian tumors that occur predominantly in young women. They arise from the undifferentiated primordial germ cells. Characteristic imaging findings include multilobulated solid masses with prominent fibrovascular septa in CT scan. However, the characteristic features are not always presented and the equivocal regional lymph nodes make the diagnosis more difficult. FDG PET/CT is useful in differentiating between malignant and benign ovarian tumors and has high specificity in detecting metastatic lymph nodes. It has considerable impact on patient diagnosis and management. We hereby present a case of ovarian dysgerminoma. The FDG PET/CT findings of the tumor and regional lymph nodes are discussed.
並列摘要
惡性胚胎瘤是好發於年輕女性的罕見卵巢腫瘤，這個腫瘤是來自於未分化的原始生殖細胞，影像上的特徵為多葉性的實體腫瘤有明顯的纖維血管間壁，但這樣的特徵有時並不容易見到，如果區域淋巴結又沒有明顯變大，要做出診斷會更為困難。氟-18去氧葡萄糖正子電腦斷層造影（F-18 FDG PET/CT）對於區分惡性和良性的卵巢腫瘤十分有用，對於淋巴結轉移的特異性也很高，因此對於病情的診斷和後續的治療方針都有相當的衝擊。在這，我們提出一個惡性胚胎瘤的病例，並討論這個腫瘤及區域淋巴結在氟-18去氧葡萄糖正子電腦斷層造影上的發現。
