Electromyographic and histological features of postpartum hypernatremic rhabdomyolysis
A 20-year-old primiparous lady was admitted with status epilepticus, which occurred 2 weeks after uneventful delivery. Blood pressure was 110/80 and the Glasgow coma scale was 4/15. She was found to have proximally dominant flaccid quadriparesis when she became conscious following seizure control. Serum CK was 15,122 units/l on the 2nd day of admission. EMG performed 7 days later revealed moderate amount of fibrillations and positive sharp waves in biceps brachii, quadriceps and tibialis anterior. Limb muscle weakness had become nearly normal at the time of EMG and serum CK level had reduced to 7,559 units. She had mild limb weakness with bilateral cerebellar ataxia at discharge and was lost from follow-up.
