His mobility had worsened, with several falls over 3 months. Two and half years before, he had been thrown from his quad bike while 3 000 feet up a mountain, hitting his head without a helmet. He had also sustained multiple mild traumatic brain injuries in childhood and adolescence due to fights, horseback riding and skiing. On neurological examination, there was bilateral deafness, left pronator drift and mild weakness throughout all four limbs (4/5 MRC). Deep tendon reflexes were symmetric and brisk throughout (3+) and cerebellar testing showed left upper arm dysmetria.MR scan of brain with susceptibility-weighted imaging (figure 1A) and T2-weighted imaging (figure 1B) showed superficial siderosis involving the Sylvian fissures, brainstem structures, cerebellar sulci and surrounding the third and lateral ventricles.
