Asthmatic amyotrophy. Three cases.

Asthmatic amyotrophy is becoming a well established clinical phenomenon. A polio-like syndrome, it is characterized by an asymmetrical lower motor neuron paralysis after an acute asthmatic episode. We are presenting three additional cases of this syndrome to add to the literature describing this phenomenon. Our cases are similar to the 18 previously reported cases showing an asymmetrical flaccid paralysis accompanied by normal sensation. The prognosis for full recovery of function is poor. Anterior horn cell damage is postulated because no sensory loss has been found in any patients.
