目的分析特发性性早熟(idiopathic central precocious puberty,ICPP)和单纯乳房早发育(premature thelarche,PT)女童的磁共振(magnetic resonance imaging,MRI)影像学特点,探讨MRI在两者鉴别诊断中的价值。方法以在河南某省级医院确诊的ICPP女童和PT女童各35例作为研究对象,均行头颅鞍区磁共振扫描,测量MRI脑垂体高度,Elster法划分脑垂体发育等级。结果垂体高度:ICPP组的均值为(5.18±1.01)mm,PT组(4.30±0.38)mm,差异有统计学意义(P<0.05);垂体形态:ICPP组Ⅳ级及以上的占82.86%,PT组Ⅳ级及以上占11.43%(P<0.05)。结论 ICPP组患儿的垂体偏高,上缘饱满;PT组患儿垂体偏低,以上缘扁平或低凹为主。磁共振脑垂体检查对ICPP与PT鉴别诊断有重要参考价值,无创无痛,可作为性早熟初诊的辅助检查。
Objective To analyze the magnetic resonance imaging (MRI) features of idiopathic central precocious puberty (ICPP) and simple premature the lamella (PT) value. Methods A total of 35 ICPP girls and PT girls diagnosed in a provincial hospital in Henan Province were enrolled in this study. All patients underwent MRI scan of the cranial sella to measure the height of the pituitary gland. The Elster method was used to classify the pituitary gland. Results Pituitary height: The average ICPP group was (5.18 ± 1.01) mm, PT group (4.30 ± 0.38) mm, the difference was statistically significant (P <0.05); pituitary morphology: ICPP group of grade Ⅳ and above accounted for 82.86% Grade IV and above PT accounted for 11.43% (P <0.05). Conclusions The pituitary in ICPP group is high and the upper margin is full. The pituitary of PT group is low, with the upper margin flat or depressed mainly. Magnetic resonance pituitary examination of ICPP and PT differential diagnosis of important reference value, non-invasive painless, can be used as a new diagnosis of precocious puberty.
