Human pulmonary dirofilariasis: an unexpected differential diagnosis for a solitary lung lesion

Ocular Dirofilariasis in Migrant from Sri Lanka, Australia

“…In Australia, estimated prevalence of the D. immitis nematode in the canine population is 20% in some areas of the east coast, home to many species and genera of mosquitoes (e.g., Aedes , Anopheles , and Culex ) ( 4 , 5 , 6 ). Of the 21 human dirofilariasis cases reported from mainland Australia in the past 40 years, most are linked to D. immitis nematode infection, and others are linked to D. repens nematode infection in returned travelers ( 1 , 4 ). We describe an imported case of human dirofilariasis of the Hong Kong genotype in Australia.…”
