The role of mechanical forces influencing the growth of a pituitary adenoma is poorly understood. In this paper we report the case of a young man with hyperprolactinaemia and an empty sella secondary to hydrocephalia, who developed a macroprolactinoma following the relief of high intraventricular pressure.
The volume of a pituitary tumour may be influenced not only by molecular but also by local mechanical factors.Intratumoural pressure, resistance of the sellar diaphragm and intracranial liquid pressure may play a role in the final size of a pituitary adenoma.The presence of hydrocephalus may hide a pituitary macroadenoma.
机械力对垂体腺瘤生长的影响尚不清楚。本文报告了一名年轻男性病例,该患者因脑积水继发高泌乳素血症和空蝶鞍,在高颅内压缓解后发展为大泌乳素瘤。
垂体肿瘤的体积不仅可能受分子因素影响,还可能受局部机械因素影响。肿瘤内压力、鞍隔阻力和颅内液体压力可能对垂体腺瘤的最终大小起作用。脑积水的存在可能掩盖垂体大腺瘤。
