Abstract

Hypophyseal triplication is malformation that has not been described previously. We present a child with midline abnormalities who underwent epignathus excision at birth. Brain MR imaging revealed 2 paired lateral pituitary glands and an oval midline gland, each with an independent stalk, connected to a thickened third ventricle floor. Because malformations represent a failure in embryogenesis, this case may provide interesting clues on the normal development of the hypophysis.

摘要

垂体三联征是一种此前未被描述过的畸形。我们报告一名患有中线异常的儿童,其出生时接受了咽上腭裂切除术。脑部磁共振成像显示有两对侧位垂体腺以及一个椭圆形的中线腺体,每个腺体都有独立的垂体柄,与增厚的第三脑室底部相连。由于畸形代表胚胎发育过程中的失败,该病例可能为垂体的正常发育提供有趣的线索。
