Spontaneous intracranial hypotension (SIH) is a secondary headache disorder due to leakage of cerebrospinal fluid without a history of dural trauma. If not diagnosed in time, patients may develop invalidating headaches or even life-threatening complications. SIH diagnosis can be challenging as the presentation of the disease may vary significantly. In this case report of a classic course of disease in a 62-year-old woman, we illustrate challenges according to the diagnosis emphasising the importance to consider SIH as a differential diagnosis in cases of orthostatic but also atypical chronic headache.
