Pulmonary dirofilariasis

Abstract

Pulmonary dirofilariasis is a benign condition, transmitted by mosquitos to humans that results in peripheral pulmonary nodules. Awareness of this entity is important in the differential diagnosis of pulmonary coin lesions.

Case report: Unusual location of Dirofilaria immitis in a 28-year-old man necessitates orchiectomy.

“…Numerous individual cases and several reviews with new cases have been reported from the United States, [1][2][3][16][17][18][19][20][21][22][23][24][25][26][27][28] Australia, 29,30 Japan, [31][32][33] and Spain. 34,35 In addition, the dirofilaria worm, though misidentified initially, has been reported in the heart 36 and the posterior vena cava.…”

A serological survey of Dirofilaria immitis infection in pet dogs of Busan, Korea, and effects of chemoprophylaxis

“…D. immitis has also been associated with human dirofilariasis, as a result of accidental infection. Cases of human pulmonary dirofilariasis have been increasingly reported worldwide (Darrow and Lack, 1981;Echeverri et al, 1999;Foroulis et al, 2005). The first Korean case of human pulmonary and hepatic dirofilariasis was recently reported (Lee et al 2000;Kim et al, 2002).…”

Spinal Lymphoma and Pulmonary Filariasis in a Pet Domestic Rabbit (Oryctolagus Cuniculus Domesticus)

“…2,5,[9][10][11][12][13][14][15][16] Features differentiating the filarid in the rabbit in the current case from other filarid nematodes include size, the prominent r coelomyarian striated muscle, and the 2 prominent lateral cords with cuticular lateral ridges. Based on an excellent review of the diagnostic features of filarids in tissue section, other filarid parasites, including Dirofilaria tenuis, Dirofilaria repens, Dirofilaria ursi, Oncocerca spp., and Brugia spp., could be eliminated from consideration based on clearly identifiable differences from the parasite described herein.…”

“…1 The identity of this filarid as D. immitis using PCR analysis was unable to be conclusively confirmed, but much of the human and veterinary literature has used less stringent histomorphologic characteristics to diagnose D. immitis. 2,4,5,[9][10][11][12][13][14][15][16] Given the geographic location of this rabbit and the endemic prevalence of heartworm disease, the most likely diagnosis of the filarid is D. immitis.…”
