We report the case of a 13-year-old girl with an increased hypophysis that mimicked an adenoma, who developed a partial empty sella on MRI after an acute episode of hydrocephalus. After replacement of a CSF shunt, the intracranial pressure returned to normal and the hypophysis filled up again all the sellar fossa. We discuss the possibility of the involvement by an ischemic atrophy of the adenohypophysis in the development of a primary empty sella with idiopathic chronic raised intracranial pressure that prevents the recovery of the gland volume after restoring the intracranial pressure to normal values. Restitution of empty sella may be an indicator of normal intracranial pressure in these cases.
我们报告了一名13岁女孩的病例，其垂体增大，类似腺瘤，在急性脑积水发作后MRI显示为部分空蝶鞍。更换脑脊液分流管后，颅内压恢复正常，垂体再次填满整个蝶鞍。我们讨论了腺垂体缺血性萎缩在原发性空蝶鞍伴特发性慢性颅内压升高发展过程中的可能作用，这种情况会阻止颅内压恢复正常后腺体体积的恢复。空蝶鞍的恢复可能是这些病例中颅内压正常的一个指标。
