It is characterized by positional orthostatic headache, pachymeningeal enhancement and low cerebrospinal fluid enhancement and normal magnetic resonance angiography while lumbar puncture revealed a cerebrospinal fluid increased intake of oral coffee which led to a gradual relief of headaches in the upright posture. Conclusions: Spontaneous intracranial hypotension can rarely present as thunderclap headache. Keywords: Thunderclap headache, Spontaneous intracranial hypotension, Meningeal enhancement Orthostatic headache, low cerebrospinal fluid (CSF) pressure, and diffuse meningeal enhancement on brain magnetic resonance imaging (MRI) are the major features of of spontaneous intracranial hypotension (SIH) characterized by positional orthostatic headache and pachymeningeal enhancement on neuroimaging that led to the pressure (<60 mmH20) in a patient presenting with a postural orthostatic headache that is not better accounted by Spontaneous low pressure, low CSF volume headaches:	./cache/work_vevci3mdq5fi3lajzvu7le2prm.pdf	./txt/work_vevci3mdq5fi3lajzvu7le2prm.txt
