Low-grade pilocytic astrocytoma.

Abstract

Introduction: A neurovascular tumor of glial proliferation derived from neuroepithelial tissue, originating in astrocytes, support cells of the central nervous system. Slow-growing, circumscribed, with low cellularity and mitotic activity. They are classified by the World Health Organization in grades I to IV, depending on their aggressiveness. Objective: To recognize the importance of the clinical method as part of professional skills. Review: It occurs in children and adolescents and represents 15% of brain tumors in children. No sex predilection. It is located in the cerebellum 42% to 60% with greater predilection. It manifests focal neurological deficit, intracranial hypertension, headache, epilepsy, hemiparesis, nausea / vomiting, non-epileptic paroxysmal episodes, absence seizures, developmental milestones, learning disorder and attention deficit hyperactivity disorder. Diagnosis is made after magnetic resonance imaging (MRI), electroencephalogram (EEG), and biopsy. Treatment is based on the location of the lesion and is primarily surgical. Conclusions: The clinical method is a systematic process that considers biological, psychological, and social aspects, essential for understanding the health status of our patients. Therefore, ongoing training allows professionals to develop skills for clinical disease detection.
