This is a case of a 30-year-old right-handed male patient who presented to the hospital in 2014 after hitting his head on the mat during a wrestling match followed by headache and temporary peripheral vision limitation. The patient’s past medical history was unremarkable. On physical examination, Glasgow Coma Scale was 15 with no focal neurological deficits. Unenhanced head computed tomography (CT) and enhanced brain magnetic resonance imaging (MRI) were performed (Figure 1). The patient was managed conservatively, and follow-up CT and MRI in 2015 (Figure 2) demonstrated significant decrease in size of the previously seen right frontoparietal lesion with also changes in its radiological features. The patient remained asymptomatic for about 3 years when in 2018 he presented to the Emergency Department with increasing headaches and peripheral vision loss. MRI demonstrated an increase in the right frontal lesion size (Figure 3). He underwent surgical resection of the lesion.
