Dirofilaria immitis (Dog heartworm - Pulmonary nodule) - Clinical guidelines.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with an incidental finding of a solitary pulmonary nodule (SPN) on chest imaging. History is significant for exposure to mosquito-endemic areas and contact with domestic canines. Patient denies constitutional symptoms, hemoptysis, or chronic cough. No prior history of malignancy or tobacco use.

Clinical Examination Findings

Pulmonary exam: Lungs are clear to auscultation bilaterally; no wheezing, rhonchi, or rales. Cardiac exam: Regular rate and rhythm, no murmurs, rubs, or gallops. Skin: No subcutaneous nodules or migratory swellings noted. General: Patient appears well-nourished, non-toxic, and in no acute distress.

Treatment Protocol

Management plan: Surgical excision via video-assisted thoracoscopic surgery (VATS) for definitive diagnosis and removal of the pulmonary nodule. Post-operative pathology to confirm Dirofilaria immitis. No systemic anthelmintic therapy is indicated for human pulmonary dirofilariasis as the parasite is typically non-viable in the human host.
