We report a case study of a 22-year-old man with a developmental learning disorder consisting of arithmetic difficulties, visuo-spatial deficits and emotional difficulties. Language abilities and verbal learning were remarkably spared. The clinical picture was consistent with the diagnosis of ‘Right Hemisphere Developmental Learning Disability’ (RHDLD) as described by Weintraub and Mesulam (Archives of Neurology 1983; 40: 463–8). Computed tomography and magnetic resonance imaging scans were normal, but a positron emission tomography scan revealed a marked hypometabolism of the right hemisphere, supporting the claim that RHDLD is indeed associated with functional abnormalities of the right hemisphere.
