title: Parietal pilomyxoid astrocytoma with recurrence in 10 months: A case report and review of literature.
abstract: Pilomyxoid astrocytoma (PMA) is a new entity described in WHO 2007 classification of brain tumors. Pilocytic astrocytoma (PA) and PMA share many histopathological features with a few differences in histopathology and behavior of the tumor. This tumor is commonly located in the hypothalamic chiasmatic region. PMA behaves more aggressively than PA, with shorter progression-free survival as well as a higher rate of recurrence and CNS dissemination. We describe a case of PMA in a 10-year-old male involving left parietal lobe presenting with raised ICP features along with the follow-up. Patient was symptom free after 7 months of postoperative and 5½ months of post-radiation. The unusual site and atypical Magnetic resonance imaging features are distinctive in this case report.
