ABSTRACT
We presented a patient with cerebral decompression sickness, who showed predominant vasogenic edema on a 3.0 Tesla (3T) magnetic resonance imaging (MRI) findings, including diffusion-weighted image (DWI) and apparent diffusion coefficient (ADC) mapping. Within minutes of surfacing, he developed paresis of the right lower limb. During transport, he began shivering, followed by severe spasm that eventually progressed to a tonic-clonic seizure. Emergent hyperbaric oxygen therapy (HBOT) was performed with U.S. Navy treatment table 6A after a treatment of seizure activity. Brain MRI was performed after hyperbaric oxygen therapy to detect any cerebral lesions, which showed subcortical hyperintensity signal changes in the left fronto-parietal region on the ADC map. Overlying cortical hyperintensity on DWI sequences and cortical hypointensity on the ADC map were simultaneously observed. Moreover, these findings disappeared in a followup MRI with complete resolution of symptoms. These findings indicate that vasogenic edema can cause cerebral decompression sickness (DCS) and that 3T MRI with DWI and ADC mapping may be useful for diagnosing cerebral DCS. In addition, these findings suggest that DW-MRI may also be useful in predicting the prognosis of cerebral DCS.
