Spontaneous regression is defined as the decrease in size or disappearance of a primary tumour or metastatic disease without therapeutic intervention. Computed tomography and magnetic resonance imaging (MRI) of the brain was performed in a 14-year-old girl experiencing sudden-onset headaches. First diagnostic exams revealed a mass in the pineal region that disappeared at three-month MRI control. Three-year follow-up MRI studies were performed. No therapy was administered, but the pineal lesion had disappeared at three-year follow-up.
