Myasthenic crisis-like syndrome due to Cleistanthus collinus poisoning.

Poisoning with Cleistanthus collinus frequently causes cardiac manifestations such as rhythm disturbances and also results in other manifestations such as metabolic acidosis and hypokalemia. We present the case of a patient who presented with a rare myasthenic crisis-like syndrome requiring assisted ventilation due to Cleistanthus collinus poisoning, which responded to treatment with neostigmine.
