Abstract：
We present the case of a 40-year-old patient with β-Thalassemia major who underwent decompressive palliative radiotherapy on symptomatic intracanal extra medullary hematopoiesis on three occasions between 2016 and 2020. We delivered normo-fractionated radiotherapy at a dose of 10Gy in five fractions on vertebrae T4 to T10 and L3 to S2, 20Gy in ten fractions on vertebrae C7 to T11, and 12Gy in six fractions on vertebrae C7 to T9. The treatment was well tolerated with complete recovery of the symptomatology during the first two irradiations, and almost complete recovery after the 3rd irradiation.
