ABSTRACT

            Pleomorphic xanthoastrocytoma (PXA) represents less than 1% of the primary neoplasms of the central nervous system (CNS). A 10-year-old female patient with 2 years presenting motor and gelastic focal seizures, presenting 2 to 3 daily convulsive episodes without improvement with anticonvulsants, magnetic resonance imaging (MRI) of the brain shows evidence of space-occupying lesion (LOE) parieto -occipital left. A left parieto-occipital craniotomy was performed, an ultrasound transducer was placed on the dura and the tumor was excised completely, the biopsy reported PXA, excellent postoperative evolution, without neurological deficit or seizures. PXA is a rare tumor of astrocytic origin. The prognosis is good when young patients, ultrasound was an effective and safe tool in tumor excision in this case, so it is recommended to perform studies in a greater number of patients.

Key Words: Pleomorphic xanthoastrocytoma, central nervous system, ultrasound. convulsions gelsthetic crisis
