Aneurysmal Bone Cyst (ABC) is a rare benign tumor in childhood, requiring definitive radiotherapy in case of inoperable recurrence. Magnetic resonance tomography (MRT) is an imaging study that is used for the diagnosis and differential diagnosis, supporting the pathohistological examination of ABC. Against the background of a rare clinical case in a 13-year-old boy, we present the significance of MRI in assessing tumor response, namely late sclerosing bone processes in ABC after definitive intensity-modulated radiotherapy (IMRT). Morphological sclerosing changes in the recurrent aneurysmal bone cyst after definitive radiotherapy are an extremely slow process that gradually leads to stabilization of the bone structure.
