title: Cerebral achromatopsia as a presentation of Trousseau's syndrome.
abstract: A 67-year-old man developed a sudden onset of achromatopsia. Magnetic resonance imaging showed occipital lobe infarction. Repeated episodes of neurological deficit referable to the posterior circulation initially suggested an embolic source, but subsequently proved to be due to a coagulopathy related to a carcinoma of the bladder. This has implications for the management of patients presenting with achromatopsia, and progressive or recurrent neurological episodes, and in particular the use of anticoagulation in this situation.
