Prolonged confusion due to absence status following metrizamide myelography
M. E. Vollmer, H. Weiss, C. Beanland and A. Krumholz
A case of absence status epilepticus resulted from metrizamide myelography.
The acute confusional state following metrizamide myelography is briefly
reviewed and compared with the confusional state resulting from adult-onset
absence status. The similarities suggest that absence status may in fact be
a relatively common cause of prolonged confusion following the use of
metrizamide. Given the difficulty in clinical diagnosis and the excellent
response to anticonvulsants, the possibility of absence status should be
specifically excluded by EEG in any person suffering prolonged confusion
following metrizamide myelography.
