en Brain Tumors Case report <div style="text-align: justify;"><span style="font-size:12px;"><strong>Background and Aim:</strong> Low-grade gliomas (LGGs) in the infratentorial region are rare in adults.<br> <strong>Case Presentation: </strong>A 31-year-old man presented with a 2-year history of neck pain and progressive numbness in the face and left arm. Neurological examination upon admission revealed no cranial nerve involvement, motor or sensory deficits, or signs of cerebellar dysfunction. The patient&rsquo;s medical history was unremarkable. Cranial magnetic resonance imaging (MRI) revealed a 2-cm T2 hyperintense lesion with focal cystic components in the right cerebellar tonsil, suggestive of a LGG.<br> The lesion was surgically removed without any complications. Post-operative MRI showed total removal of the tumor. Histopathological analysis confirmed the lesion to be a pilocytic astrocytoma. No adjuvant therapy was given, and the patient is recurrence-free at 1-year follow-up.<br> <strong>Conclusion:</strong> This case underlines the possibility of such rare diagnoses in adult patients and the effectiveness of the surgical treatment.</span></div> Astrocytoma, Glioma, Infratentorial neoplasms, Case report 225 228 http://irjns.org/browse.php?a_code=A-10-661-2&slc_lang=en&sid=1 Bilal Bahadır Akbulut b.bahadirakbulut@gmail.com 100319475328460011991 100319475328460011991 Yes Department of Neurosurgery, Faculty of Medicine, Ege University, Izmir, Turkey.
