[A case of sodium bromate intoxication with cerebral lesion].
We confirmed a cerebral lesion due to sodium bromate intoxication on MRI, SPECT, auditory brainstem response (ABR) and sensory evoked potential (SEP). The patient was 34 years old, and ingested sodium bromate (14 g) to commit suicide. Vomiting, epigastralgia, watery diarrhea and anuria appeared after 30 minutes and he became deaf within 12 hours. Renal function recovered after hemodialysis. Renal biopsy revealed acute renal tubular necrosis. After one month, burning pain appeared in bilateral lower extremities. Sporadic, clear and small high intensity spots were observed in the deep white matter of the right occipitotemporal border zone and bilateral centrum semiovale on T2 and proton weighted images of brain MRI. IMP-SPECT disclosed partial low perfusion in the left parietal gray matter. Central conduction time was delayed on ABR and SEP. The clinical symptoms and course together with laboratory studies suggest that the cerebral lesion was due to direct sodium bromate intoxication.
