Abstract:
A 59-year-old man with a history of major depression was found by his wife to be unconscious and foaming at the mouth. On arrival at the emergency department, the patient was noted to be unresponsive. Computed tomography of the brain showed symmetrical ill-defined areas of hypoattenuation involving the medial aspects of both lentiform nuclei, while magnetic resonance images of the brain showed symmetrical increased signal in the bilateral globi pallidi on diffusion weighted, T2-weighted and fluid attenuated inversion recovery sequences. These findings were those of acute carbon monoxide poisoning. Despite aggressive treatment, the patient's condition continued to deteriorate and he eventually passed away. The various imaging findings of carbon monoxide poisoning in the brain and the differential diagnoses are discussed.
