Abstract

Ovarian thecoma is a benign and rare neoplasm that accounts for 0.5% to 1% of all ovarian tumors. A 55-year-old woman with known breast cancer underwent a metastatic workup before surgery. The Tc-MDP whole-body bone scan revealed intense uptake in the left pelvic region. Hybrid SPECT/CT imaging showed that the elevated Tc-MDP activity was in a tumor with calcification in the left adnexa. Dynamic enhanced MRI revealed marked enhancement of the tumor. Resection of the tumor was subsequently performed, and pathologic analysis confirmed the diagnosis of an ovarian thecoma.

摘要

卵巢卵泡膜细胞瘤是一种良性且罕见的肿瘤，占所有卵巢肿瘤的 0.5%至 1%。一位 55 岁的已知患有乳腺癌的女性在手术前进行了转移性检查。Tc-MDP 全身骨扫描显示左骨盆区域有强烈摄取。混合 SPECT/CT 成像显示，Tc-MDP 活性升高的部位是左侧附件有钙化的肿瘤。动态增强 MRI 显示肿瘤明显增强。随后进行了肿瘤切除术，病理分析证实了卵巢卵泡膜细胞瘤的诊断。
