Without regular follow-up, the complete radiological remission lasted almost 5 years; in July 2011, the patient experienced the first intracranial relapse of multiple lesions, located in the right temporal lobe, parietal lobe, occipital lobe, and the left frontal lobe regions ( Figures 1A, B ), which had already received a boost of radiotherapy in 2006. A follow-up MRI scan in September 2011 revealed that metastatic brain lesions regressed significantly ( Figures 1C, D ).

There were no signs of progression until January 2016, when a relapse was located on the left parieto-temporal lobe ( Figures 2A - C ).
