One month after the patient’s admission, notable progress was observed in alleviating symptoms across the limbs, trunk, and abdomen. This improvement allowed for intermittent disconnection from the ventilator. Electromyography promptly conducted on all four limbs revealed multifocal peripheral nerve damage, characterized by electrophysiological indications of early axonal injury. Notably, repetitive electrical stimulation yielded no abnormalities (refer to Table 2). Furthermore, magnetic resonance imaging (MRI) of the head in conjunction with magnetic resonance angiography (MRA) exhibited a lack of discernible abnormalities (see Figure 1).
In response to the patient’s condition, an aggressive regimen of plasma exchange therapy was initiated. This encompassed a total of five exchanges performed on alternate days. Encouragingly, upon completion of the fifth plasma exchange session, noticeable finger movement was observed in the patient’s extremities.
