Spontaneous nerve root cerebrospinal fluid leaks and intracranial hypotension: case report

Spontaneous intracranial hypotension is a rare syndrome, characterized by pressure in the cerebrospinal fluid ranging between 50 and 70 mmH2O and postural headache. Its diagnosis is made through the clinical presentation, measurement of the cerebrospinal fluid pressure and neurorimage features. The clinical recognition of this pathology has been increasing and the differential diagnosis must be made with inflammatory meningeal processes and tumor. We report a case of spontaneous nerve root cerebrospinal fluid leaks in a 34 year-old man and intracranial hypotension. A literature review was performed evaluating the clinical, diagnostic and therapeutic aspects of this unusual pathology.
