A 39-year-old man presented for evaluation with several months of progressive upper extremity pain and weakness. MRI of the cervical spine revealed an intramedullary ring-enhancing lesion centred at C3-C4. Following subtotal surgical resection, a diagnosis of glioblastoma (GBM) was confirmed. Subsequent testing at a later date revealed an H3K27M mutation. He was initially treated with radiation and concomitant and adjuvant temozolomide. He had multiply recurrent disease and was treated with various regimens, including the histone deacetylase inhibitor valproic acid. The patient passed away 31 months (~2.5 years) after diagnosis. Our case is one of few reported adult spinal cord GBMs possessing the H3K27M mutation, and one with the longest reported overall survival in the literature to date. ER -
