A 49-year-old male who had unconsciousness and of limb tics after H2S inhalation in a fish hold was admitted to our hospital after 51 days of treatment in another hospital and was still in a coma and had hypermyotonia in the four limbs on admission. CT of the brain was performed 53 days after the poisoning and revealed symmetrical stripes and patchy hypodensities in the bilateral basal ganglia (a); MRI on the same day revealed symmetrical hypointensities on T1WI and hyperintensities on T2WI around the lateral ventricles and in the bilateral basal ganglia (putamen and head of the caudate nucleus) (b), and the lesions were slightly hyperintense on T2WI-FLAIR (c) and DWI (d); CT of the brain 93 days after the poisoning was comparable to the previous CT (e), and MRI on the same day revealed that the ranges of lesions on T2WI (f) and T2WI-FLAIR (g) were also comparable to those on the previous MRI, but reduced hyperintensities were revealed on DWI (h); MRI of the brain performed 6 months after poisoning revealed that there were still no significant changes in the lesions. The patient had a poor prognosis and was in a persistent coma
