title: Normal pressure form of the spontaneous intracranial hypotension: a case report with pituitary enlargement and asymptomatic pituitary haemorrhage.
abstract: Spontaneous intracranial hypotension is a rare condition caused by spontaneous cerebrospinal fluid leak and volume depletion. It is initially misdiagnosed as a cause of an orthostatic headache, which is the most important symptom of the syndrome. It can be presented as one of four types: classic form, normal pressure form, normal pachymeninges form and acephalgic form. The diagnosis is made based on the clinical presentation, physical examination, typical cerebrospinal fluid and magnetic resonance imaging findings. We present a case of a 29-year-old woman with uncommon normal pressure form of the spontaneous intracranial hypotension, characterized by normal cerebrospinal fluid opening pressure, and typical clinical and magnetic resonance imaging findings, including the finding of pituitary gland enlargement with asymptomatic pituitary haemorrhage as an unusual complication.
