To examine whether the pituitary gland enlarges in patients with spontaneous intracranial hypotension (SIH).
All six patients were women ranging in age from 17 to 51 years. They developed severe headache that was completely relieved by lying flat, and MR imaging showed diffuse enhancement of the pachymeninx. They were clinically diagnosed with SIH. The height of the pituitary gland was measured on midsagittal MR image.
Pituitary heights ranged from 8 to 11 mm. The measurements were greater than the size of the normal pituitary gland in women described age-matched in the previous report. In one case, follow-up MR images showed that the size of the pituitary gland was decreased from 11 to 5 mm in height.
The pituitary gland was enlarged in all six patients with SIH on MR images. SIH may cause enlarged pituitary gland.
研究自发性颅内低压（SIH）患者的垂体是否会增大。
6例患者均为女性，年龄在17至51岁之间。她们出现严重头痛，平躺后完全缓解，磁共振成像（MR）显示硬脑膜弥漫性强化。临床诊断为SIH。在矢状位MR图像上测量垂体高度。
垂体高度在8至11毫米之间。这些测量值大于先前报告中年龄匹配的正常女性垂体大小。1例患者的随访MR图像显示垂体高度从11毫米降至5毫米。
6例SIH患者的MR图像均显示垂体增大。SIH可能导致垂体增大。
