目的：探讨早产儿、足月儿、婴幼儿及成人透明隔腔(CSP)发育的特点。方法观察无颅脑畸形的早产儿(27~37周)141例；足月儿(38~41周)106例；婴幼儿(1~3岁)171例；成人35046例颅脑 MR 图像,研究 CSP 的检出率及其形态特点,测量其横径宽度。结果(1)CSP 检出率在早产儿为100.00%(141/141),足月儿为97.17%(103/106),婴幼儿为2.26%(4/177),成人为0.82%(287/35046)。(2)CSP 形态在早产儿为柱状44.00%、三角状56.00%,在足月儿为三角状76.40%、裂隙状23.60%,在婴幼儿和成人3种形态各占1/3左右。(3)CSP 平均宽度在早产儿为5.7 mm,足月儿4.1 mm,婴幼儿13.3 mm,成人14.3 mm。结论 CSP 是人类脑发育过程中一个阶段表现,出生后很快闭合,婴幼儿和成人仅有少数遗留 CSP。

Objective To study the development characteristics of cavum sepit pellucidun (CSP)in prematures,neonates,infants and adults with MRI.Methods Brain MR images of different subjects including 141 prematures,106 neonates,171 infants and 35 046 adults were observed to determine the incidence and shape of CSP,and to measure its transverse diameter.Results CSP incidences were 100% (141/141)in prematures,97.17% (103/106)in neonates,2.26%(4/177)in infants and 0.82% (287/35 046)in adults respectively,and the CSP was cylinder (44.00%)or triangle in shape (56.00%)in prematures,triangle (76.40%)or fissure in shape (23.60%)in neonates.For infants or adults,each shape accounted for about a third of three kinds of shape respectively.Its mean transverse diameters were 5.7 mm in prematures,4.1 mm in neonates,13.3 mm in infants and 14.3 mm in adults respectivity.Conclusion CSP has different performances at development periods in human being brain.Most close after birth,while fewer remain in the whole life.
