Hipertensión intracraneal idiopática y fístula espontánea de líquido cefalorraquídeo. Utilidad de la monitorización de la presión intracraneal

Spontaneous cerebrospinal fluid (CSF) fistulas are rather common in daily practice. The aim of the surgical treatment is closure of the leak, but recurrences are quite frequent. The association between spontaneous CSF fistulas and idiopathic intracranial hypertension (IIH) is not uncommon, and this is probably the cause of the low rate of success of the surgical treatment. Symptoms of IIH associated with spontaneous CSF fistula are atypical, and diagnosis is often missed. Continuous intracranial pressure monitoring is very useful in the diagnosis of chronic IIH and in patients with spontaneous CSF fistula, as it helps in making decisions on the treatment of these patients.
