Akhunzada","Gohar Javed","Zeeshan Uddin","Yasir A. Khan"],"abstract":"Background: Pilocytic astrocytoma (PA) is the most prevalent central nervous system (CNS) tumor in pediatric population and accounts for an approximate of 5–6% of all gliomas. This neoplasm can occur at all levels of the neuraxis, with majority (67%) arising in the cerebellum and optic pathway. PAs are World Health Organization Grade I tumors and are the most benign of all astrocytomas characterized by an excellent prognosis. Other differentials include subependymal giant cell astrocytoma (SEGA), ependymoma, meningioma, and low-grade gliomas such as pilocytic or diffuse astrocytoma; calcification is more commonly regarded as a feature of benign or slow-growing tumors. Case Description: We present a case of a 17-year-old female presenting with an unusual cause of hydrocephalus, a rare case of a calcified pilocytic astrocytoma as an intraventricular tumor. Conclusion: PA rarely presents as an intraventricular tumor and should be included in the differential diagnosis of a large mass with massive intratumoral calcification.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/d66f9b1c-326d-4f23-916d-765c12e8b74f/featured/hero-1782420919660.png","publishDate":"2017-06-13T00:00:00.000Z","doi":"10.4103/sni.sni_468_16","categories":["Pediatric Neurosurgery","Case Report"],"fullTextUrl":"http://surgicalneurologyint.com/wp-content/uploads/2017/06/8439/SNI-8-116.pdf"}
