Resumen

SOSA, Fidel; RODRIGUEZ, Facundo; PALMA, Fernando  y  ZUCCARO, Graciela. Presentación inusual de los quistes aracnoideos. Rev. argent. neurocir. [online]. 2006, vol.20, n.3, pp. 121-125. ISSN 1850-1532.

Objetive: To analyze and describe the association between arachnoid cysts and subdural hygroma. This association is an unusual complication of which only 24 cases have been reported in the literature. Methods: The clinical records of 5 patients with arachnoid cysts presenting as a subdural hygroma with increased intracranial pressure were analyzed retrospectively. Results: The ages of the patients ranged between 3 and 15 years (mean: 7 years). M/F ratio was 3/2. Onset of symptoms was postraumatic in 3 and spontaneous in 2. All patients presented symptoms of increased intracranial pressure and bilateral papilledema, and in 2 out of 5 paresis of the VI cranial nerve was found. All children underwent CAT scan and MRI was performedin 2. In all patients, subdural hygroma with mass effect and arachnoid cyst of the middle fossa was found. Emergency surgery was carried out in all cases. All patients evolved favorably with complete disappearance of the subdural hygroma. They are currently asymptomatic with normal neurological examination and fundoscopy. Conclusion: Even though subdural hygroma with increased intracranial pressure is an unusual complication, it should be known as one of the clinical presentations of arachnoid cysts, which required immediate surgical intervention.
