Haycocknema perplexum: an emerging cause of parasitic myositis in Australia.

Haycocknema perplexum is a rare cause of parasitic myositis, with all cases of human infection reported from Australia. This case involved an 80-year-old Queensland wildlife carer, who presented with muscle weakness, mild eosinophilia and creatine kinase elevation. This case supports an association with native animal contact and highlights the debilitating nature of this infection.
