• Astrocytomas are the single largest group of all primary central nervous system (CNS) neoplasms. • They are currently classified according to histological features and the subtypes prevalence differs on peak age. • The pilocytic subtype occurs almost exclusively in children and frequently in the posterior fossa. • Despite the fact that diffuse subtypes are more common in adults and mostly located in the cerebral hemispheres, pilocytic astrocytoma should not be discarded from differential diagnosis, regardless of age or lesion topography.  

• Review of our prospective database of CNS neoplasms between January and December 2013. • A total of 255 CNS tumors were found, with 10 pilocytic astrocytomas. Of these, 3 were found in adults above 60 years-old. One was infratentorial and the other two were hemispheric. • Clinical data, imagiological findings and pathological features were analyzed.
