The aim of the study was to characterize magnetic resonance imaging findings in patients with recurrent ovarian adult granulosa cell tumors (AGCTs).
Clinical and magnetic resonance imaging manifestations of recurrent AGCTs were evaluated in 11 patients.
Initial recurrences of AGCT were diagnosed between 13 months and 30 years (mean, 11.3 years). Recurrent tumors were located in the pelvic peritoneum, the abdominal peritoneum, the retroperitoneum, and bone. The number of recurrent tumors varied from 1 to 5. Tumors varied in morphology and all margins were well circumscribed. The internal structures noted were as follows: multilocular cystic and solid and cystic. Furthermore, internal hemorrhage and sponge-like multicystic components were identified.
Ovarian AGCTs recurred in the pelvic peritoneum, abdominal peritoneum, and the retroperitoneal lymph nodes. Large recurrent AGCTs were commonly well circumscribed, round or lobulated, and multilocular cystic or solid and cystic. Moreover, they frequently included internal hemorrhage and sponge-like multicystic components.
本研究旨在描述复发性卵巢成人颗粒细胞瘤（AGCT）患者的磁共振成像表现。
对11例复发性AGCT患者的临床和磁共振成像表现进行评估。
AGCT的初次复发诊断时间为13个月至30年（平均11.3年）。复发性肿瘤位于盆腔腹膜、腹部腹膜、腹膜后和骨骼。复发性肿瘤的数量为1至5个。肿瘤形态各异，所有边缘均清晰。观察到的内部结构如下：多房囊性、实性和囊性。此外，还发现了内部出血和海绵状多囊成分。
卵巢AGCT复发于盆腔腹膜、腹部腹膜和腹膜后淋巴结。大型复发性AGCT通常边界清晰，呈圆形或分叶状，多房囊性或实性和囊性。此外，它们常包含内部出血和海绵状多囊成分。
