Abstract

Abstract Diffuse Intrinsic Pontine Gliomas (DIPG) is a rare and highly aggressive central nervous system tumour arising from glial cells which occur mostly in children. It remains a potentially deadly cancer despite treatment, with the highest mortality rate, in which most children die within 1-year of diagnosis. Radiation therapy might improve the clinical symptoms, but the results are temporary, with tumor progression typically occurring months post radiation, whereas chemotherapy remains controversial. Here we present a case report of a patient with DIPG Indonesia and how we diagnose and currently treat it. An eight years-old boy presented with decrease level of consciousness with headache, limb weakness, slurred speech, double vision, hemifacial weakness, paraplegia, and disequilibrium which worsened two weeks prior to admission. He was initially noted to have a medially inverted left eye two months prior to admission. On physical examination, there was a N.VI and N.VII palsy, hyperreflexia, paraplegia, and nystagmus. Head MRI demonstrated a solid with minimal enhancement after contrast administration in the left pons region extending into mesencephalon with cystic component and flat floor of fourth ventricle sign, causing hydrocephalus, suggestive diffuse intrinsic pontine glioma. He was given fractionated focal intensity modulated radiation therapy (IMRT) to the tumor along with 5 mm margins with a total dose of 54 Gy. 1.8 Gy fractions, given once daily for 5 days per week over a period of 6 weeks. Supportive care in the form of corticosteroids is used to treat the peri-tumoral edema. There was a short period of motoric improvement. But then the disease progressed with the latest head CT showed hydrocephalus formation with increased size of mass. He is treated with chemotherapy using Temozolomide, and currently alive after 3 months post diagnosis. Keywords: childhood brain tumour, Diffuse Intrinsic Pontine Glioma, radiation therapy
