A rare case of H3K27-altered diffuse midline glioma with multiple osseous and spinal metastases at the time of diagnosis.

BACKGROUND: H3K27-altered diffuse midline gliomas are uncommon central nervous system tumors with extremely poor prognoses. CASE PRESENTATION: We report the case of a 24-year-old man patient with multiple, inter alia osseous metastases who presented with back pain, hemi-hypoesthesia, and hemi-hyperhidrosis. The patient underwent combined radio-chemotherapy and demonstrated temporary improvement before deteriorating. CONCLUSIONS: H3K27-altered diffuse midline glioma presents an infrequent but crucial differential diagnosis and should be considered in cases with rapid neurological deterioration and multiple intracranial and intramedullary tumor lesions in children and young adults. Combined radio-chemotherapy delayed the neurological deterioration, but unfortunately, progression occurred three months after the diagnosis.      «
