Presentation
An asymptomatic patient with a pulmonary coin lesion surgically diagnosed with pulmonary dirofilariasis caused by infection with Dirofilaria immitis (D. immitis) is presented. [ncbi.nlm.nih.gov]
Entire Body System
- Chills
[…] may infect humans as secondary end stage host, particularly in southern coastal states in US Adult worms die in right ventricle, embolize in pulmonary arterial circulation Embolization of dead worms may be clinically silent or cause chest pain, fever, chills [pathologyoutlines.com]
- Inguinal Hernia
This case was unique in that it involved the spermatic cord, produced significant symptoms, and upon physical examination was suspected of being an incarcerated inguinal hernia. [ncbi.nlm.nih.gov]
Cardiovascular
- Vascular Disease
The parasite can survive for long periods of time (7 years or more) in the circulatory system of immunocompetent reservoirs, producing usually a chronic inflammatory vascular disease. [ncbi.nlm.nih.gov]

Eyes
- Foreign Body Sensation
A 51-year-old man from the Emilia-Romagna region of northeastern Italy referred for ocular foreign body sensation in his right eye. A slight swelling of the bulbar conjunctiva was observed. [ncbi.nlm.nih.gov]
Psychiatrical
- Suggestibility
These findings suggest that the ES antigen of D. immitis provides a more sensitive antigen than does the adult somatic antigen; but the ES antigen and the adult somatic antigen have a common antigenic band at 18 kDa. [ncbi.nlm.nih.gov]
Neurologic
- Confusion
These species are responsible for the development of benign pulmonary and subcutaneous nodules, respectively, that can be confused with lung or cutaneous cancer. [ncbi.nlm.nih.gov]

- Pulmonary Coin Lesion
Konstantinos Grapatsas, Gian Kayser, Bernward Passlick, Sebastian Wiesemann Abstract A solitary pulmonary coin lesion can be attributed to a great variety of diseases. [jtd.amegroups.com]

Microbiology
- Wuchereria Bancrofti
Abstract In French Polynesia, Aedes polynesiensis (Marks) is the vector of the human filarial parasite Wuchereria bancrofti (Cobbold) and dog heartworm, Dirofilaria immitis (Leidy). [ncbi.nlm.nih.gov]

Treatment
None required systemic treatment. D. immitis is found in dog, cat, wolf, coyote, and fox populations throughout the United States, but the highest concentrations have been noted in the eastern, southeastern, and southern coastal states. [ncbi.nlm.nih.gov]

The presence of Dirofilaria will impact the course and/or choice of treatment. The Knott’s test can be done without doing a direct smear, but never do a direct smear without doing a Knott’s test. [sonopath.com]
Etiology
One of the extremely rare etiologies of the solitary pulmonary coin lesion is the human pulmonary dirofilariasis (HPD). HPD is attributed to an infection of the parasite Dirofilaria (D.) and especially to the type Dirofilaria immitis (DI). [jtd.amegroups.com]
Epidemiology
The epidemiologic, morphologic, and clinical features of D immitis infestation are discussed. [ncbi.nlm.nih.gov]

Pathophysiology
This results has important bearing on the dynamics of heartworm-induced pathophysiological changes during infection and could influence the nature and chronology of responses to therapy. [ncbi.nlm.nih.gov]
Prevention
INTERPRETATION & CONCLUSION: D. immitis is circulating in wildlife of the study area, suggesting the relevance of developing control programmes to prevent transmission of the disease to humans and domestic animals. [ncbi.nlm.nih.gov]
He has not been on any heartworm preventative since that time. Fisher has not had any vomiting or diarrhea recently but has been having slightly looser stools. [web.archive.org]
