We described an intracranial immature teratoma in a 13 year old Malay boy who presented with history of chronic headache and blurring of vision. Physical findings revealed bilateral papilloedema but no other localizing sign. A Magnetic Resonance Imaging of the brain revealed a suprasellar well defined lobulated midline heterogenous mass which was intraoperatively described as mainly solid tumour with multiple small cystic component filled with yellowish jelly like material. Histopathological finding confirmed the case as immature teratoma. Molecular genetic analysis of p53 and p27 genes revealed substitution of nucleotide G to C at location nucleotide 12139, exon 4 of gene p53. No alteration was detected at exon 5-6 and 8 of p53 gene and exon 1 and 2 of p27 gene. This is the first case report of an intracranial immature teratoma with genetic mutation occuring in a Malay boy.

patients, families as well as the surrounding communities,especially the healthcare services. It can be classified intoeither a benign slow growing tumour (non-cancerous) andmalignant tumour (cancerous). The purpose of this studywas to determine the incidence and pattern of brain tumouradmitted to the Neurosurgery Department in HospitalSultanah Nurzahirah (HSNZ), Terengganu, Malaysia.Methods: This is a retrospective study of incidence andpattern of BT admitted to the Neurosurgery Department inHSNZ. Data was collected from the yearly census of BTregistered from 2013 to 2018.Results: A total number of 386 new cases of primary BT wereregistered. The number of cases of BT was found to belowest among children (0 to 10 years old) with only 4.4% butat peak among elderly aged between 51 to 60 years old(26.2%). As for gender, males constituted about 44.5%(n=172) whereas females accounted for 55.5% (n= 214) of thecases. In total, meningioma was found to have the highestincidence (27.2%) followed by metastases brain tumour(18.1%) and glioma (17.4%). Conclusions: This study has shown that the incidence of BTwas led by meningioma which had a high prevalence amongthe elderly population, followed by metastasis BT andgliomas.
