纵隔生殖细胞肿瘤的CT表现—附40例病例报告

Zhongshan Daxue xuebao. Yixue kexue ban, 2011
【目的】分析40例纵隔生殖细胞肿瘤的CT征象，提高其CT诊断准确性。【方法】回顾性分析40例病理证实的纵隔原发生殖细胞肿瘤的CT资料，24例为畸胎瘤，16例为非畸胎类生殖细胞肿瘤，40例均行CT平扫和增强扫描，观察征象包括：发病部位，肿瘤大小，轮廓，边缘，平扫和增强扫描CT值，对于临近结构的侵犯，有无远处转移。【结果】40例肿瘤均位于前纵隔，肿瘤的最大径为5 cm~16 cm；24例畸胎瘤边界清楚，呈类圆形，CT平扫20例可见脂肪密度影和钙化，增强轻度强化，4例呈均匀水样密度,肿瘤壁薄均匀，见弧线状钙化，
