Spontaneous Intracranial Hypotension (SIH) is formed as a result of the leakage of cerebrospinal fluid (CSF) into the extradural space. The most common symptom caused by SIH is headache associated with changes in body position. Imaging, especially magnetic resonance imaging (MRI) of the head and spine with contrast, is the most important examination method in the diagnosis of SIH. In the case of no improvement after symptomatic treatment, surgery is very effective, especially in the case of finding the site of CSF leakage within the spinal canal.
A case report: We present a case of a 28-year-old patient with 2- month history of severe increasing headaches. The patient denied any head injuries, nasal CSF leakage or lumbar puncture in the past. The neurological examination showed no abnormalities. MRI of the head showed typical features of the intracranial hypotension syndrome. MRI of the cervical spine revealed potential sites for leakage of the cerebrospinal fluid at the C1-C2 level. The patient was qualified for surgical treatment - dural plastic surgery in the cervical section. After treatment the symptoms of intracranial hypotension resolved, and subsequent control MRI examinations showed regression of typical changes of the spontaneous intracranial hypotension.
Conclusions: The authors would like to take notice that imaging diagnostics due to headaches should include MRI of the head and spine, as it is the most important test in diagnosing SIH. Moreover, surgical treatment is a quick and very effective method of treatment.
