Three patients with Australian parasitic myositis caused by the muspiceoid nematode Haycocknema perplexum are described. Treatment with albendazole led to a slow and incomplete recovery, but treatment with steroids caused life-threatening deterioration.

A 23-year-old woman presented to Cairns Base Hospital with a history of 2 years of insidiously progressive weakness, including 1 year of difficulty swallowing. She weighed 42 kg, having lost 18 kg in recent years. There had been no myalgia.
