Spontaneous intracranial hypotension (SIH) is an unusual syndrome that is characterised by positional headache, neck rigidity, nausea and vomiting. The characteristic magnetic resonance imaging (MRI) findings are diffuse smooth pachymeningeal thickening and enhancement, downward displacement of posterior fossa structures and pituitary gland enlargement. An unusual case of SIH with pituitary macro-adenoma and subsequent subdural haemorrhage is presented, and its clinical picture, MRI findings and possible pathophysiological mechanism are discussed.
自发性颅内低压（SIH）是一种罕见的综合征，其特征为体位性头痛、颈部僵硬、恶心和呕吐。特征性的磁共振成像（MRI）表现为硬脑膜弥漫性光滑增厚和强化、后颅窝结构向下移位以及垂体增大。本文报告了一例伴有垂体大腺瘤及随后发生硬膜下出血的罕见SIH病例，并讨论了其临床表现、MRI表现及可能的病理生理机制。
