Abstract

Abstract: A 34-year-old woman underwent 18 F-FDG PET/CT scan following a diagnosis of an invasive mole. Although CT indicated multiple lung metastases, FDG uptakes were not evident. In contrast, FDG uptakes were observed in the pelvic lesion including the left ovary, suggestive of ovarian metastasis. MRI disclosed a ring-shaped enhancement typical of a corpus luteum. This corpus luteum was supposed to be maintained by the elevated human chorionic gonadotropin excreted from the invasive mole. This case underlines the importance of careful interpretation of 18 F-FDG PET/CT in the evaluation of invasive moles, highlighting potential false positive in corpus luteum.

利用 18F-FDG PET/CT 诊断侵袭性痣的挑战。

摘要：一名 34 岁的女性在确诊为侵袭性痣后接受了 18F-FDG PET/CT 扫描。虽然 CT 显示有多个肺转移灶，但 FDG 摄取并不明显。与此相反，盆腔病灶（包括左侧卵巢）出现了 FDG 摄取，提示卵巢转移。核磁共振成像显示黄体有典型的环形强化。该黄体应该是由浸润性痣排出的升高的人类绒毛膜促性腺激素维持的。该病例强调了在评估浸润性痣时仔细解读18F-FDG PET/CT的重要性，并强调了黄体潜在的假阳性。
