A 17-year-old male was found to have a fourth cranial nerve palsy and chronic papilloedema following his presentation to our institution with a 6-week history of blurred vision in both eyes and vertical binocular diplopia. A diagnosis of pineal germinoma was made following imaging studies and endoscopic neurosurgical biopsy of the tumour. He was diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) 3 years earlier and treated with amphetamines. Since this diagnosis, he continued to suffer from hyperactive behaviour, poor concentration, worsening headaches and insomnia. Pineal pathology has a known association with sleep disturbance through the disturbance of melatonin synthesis and/or metabolism. This case report serves to highlight how the presence of organic brain disease presenting to an eye department can be masked by a diagnosis of ADHD.
