目的：探讨卵巢卵黄囊瘤（YST）CT及MRI影像学特征，以提高对该病影像学诊断的准确率。方法回顾性分析7例经手术后病理证实的卵巢卵黄囊瘤的CT、MRI资料，其中3例术前行CT平扫及增强扫描，3例行MRI平扫与增强扫描，1例行MRI平扫。7例术前均检测血清AFP浓度。结果??所有病例均为单侧发病，左侧5例，右侧2例，肿瘤最大径6.0?~?20.1?cm，平均最大径13.5?cm。CT表现：3例为巨大类圆形囊实性包块，以囊性成分居多，边界清楚，密度不均匀，实性部分均呈轻中度强化，2例见纡曲肿瘤血管影，肿瘤内部均未见明显钙化灶。MR表现：4例为类圆形巨大占位，边界清楚，3例为囊实性改变，信号混杂，其内可见囊变坏死；1例以囊性成分为主，囊壁及囊腔内有数个实性结节，3例实性部分均明显强化。病理表现：镜下观察肿瘤组织结构复杂，瘤细胞排列多样，背景基质疏松，可见特征性Schiller-Dural小体，瘤组织内可见散在分布的透明小体。7例术前血清AFP均明显升高602?~?48,214μg/L，平均28,823μg/L。结论??卵巢卵黄囊瘤具有一定的CT、MR特征，结合临床资料及血清AFP，术前可做出正确诊断。
目的：探討卵巢卵黃囊瘤（YST）CT及MRI影像學特徵，以提高對該病影像學診斷的準確率。方法迴顧性分析7例經手術後病理證實的卵巢卵黃囊瘤的CT、MRI資料，其中3例術前行CT平掃及增彊掃描，3例行MRI平掃與增彊掃描，1例行MRI平掃。7例術前均檢測血清AFP濃度。結果??所有病例均為單側髮病，左側5例，右側2例，腫瘤最大徑6.0?~?20.1?cm，平均最大徑13.5?cm。CT錶現：3例為巨大類圓形囊實性包塊，以囊性成分居多，邊界清楚，密度不均勻，實性部分均呈輕中度彊化，2例見紆麯腫瘤血管影，腫瘤內部均未見明顯鈣化竈。MR錶現：4例為類圓形巨大佔位，邊界清楚，3例為囊實性改變，信號混雜，其內可見囊變壞死；1例以囊性成分為主，囊壁及囊腔內有數箇實性結節，3例實性部分均明顯彊化。病理錶現：鏡下觀察腫瘤組織結構複雜，瘤細胞排列多樣，揹景基質疏鬆，可見特徵性Schiller-Dural小體，瘤組織內可見散在分佈的透明小體。7例術前血清AFP均明顯升高602?~?48,214μg/L，平均28,823μg/L。結論??卵巢卵黃囊瘤具有一定的CT、MR特徵，結閤臨床資料及血清AFP，術前可做齣正確診斷。

MethodsCT?and?MRI?findings?of?7?cases?of?pathologically?confirmed?yolk?sac?tumor?were?analyzed?retrospectively.?Plain?and?enhanced?CT?scan?were?performed?in?3/7?cases.?MRI?plain?and?enhanced?scan?in?3/7?cases,?and?only?MRI?plain?scan?in?1/7?cases.?Alpha?fetal?protein(AFP)concentration?in?serum?was?measured?for?all?cases?prior?to?the?surgery. ResultsIn?all?cases?there?were?unilateral?ovarian?masses.?5?cases?in?the left side, and 2 in the right side. The maximum diameter of masses were 6.0 ~ 20.1 cm. The average maximum diameter was 13.5 cm. CT images showed: all the tumors were mixed solid and cystic, and predominantly cystic, with?clear?boundary?and?uneven?density.?The?solid?part?of?mass?was?moderate?enhanced.?2?cases?showed?tortuous?tumor?vessels?inside?the?tumor,?there?was?no?obvious?calcification.?MR?images?showed:?the?tumors?in?all?4?cases?were huge space occupying masses with clear boundary. Among them, 3 cases were mixed solid and cystic with heterogeneous?signal,?cystic?necrosis?area?inside.?The?solid?part?of?the?3?cases?was?obviously?enhanced.?The?other?1?case?showed?cystic,?with?several?solid?nodules?in?the?cystic?wall?and?cavity.?The?average?serum?AFP?concentration of all cases was 28, 823 μg/L with a range of 602 ~ 48, 214 μg/L.
