We present the case of an asymptomatic 59-year-old male found to have a 13 mm left upper lobe nodule on CT scan.\u00a0 The patient was asymptomatic and the CT was performed to follow up mediastinal and hilar lymphadenopathy that had been stable on several previous CT scans.\u00a0 He had a history of emphysema and reported a 15 pack-year smoking history.\u00a0 PET-CT was performed which demonstrated mild 18-FDG uptake within the nodule. Given his age and smoking history, malignancy was a consideration and he underwent a wedge resection.\u00a0 Pathological examination revealed a necrobiotic granulomatous nodule with a central thrombosed artery containing a parasitic worm with internal longitudinal ridges and abundant somatic muscle, consistent with pulmonary dirofilariasis. Dirofilaria immitis, commonly known as the canine heartworm, rarely affects humans.\u00a0 On occasion it can be transmitted to a human host by a mosquito bite.\u00a0 There are two major clinical syndromes in humans: pulmonary dirofilariasis and subcutaneous dirofilariasis.\u00a0 In the pulmonary form, the injected larvae die before becoming fully mature and become lodged in the pulmonary arteries.<\/jats:p>","DOI":"10.3941\/jrcr.v9i4.1869","type":"journal-article","created":{"date-parts":[[2015,4,29]],"date-time":"2015-04-29T23:09:15Z","timestamp":1430348955000},"page":"28-33","source":"Crossref","is-referenced-by-count":11,"title":["18-FDG Uptake in Pulmonary Dirofilariasis"],"prefix":"10.3941","volume":"9","author":[{"given":"Michael","family":"Stone","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ishani","family":"Dalal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chad","family":"Stone","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bhavin","family":"Dalal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2326","published-online":{"date-parts":[[2015,4,19]]},"container-title":["Journal of Radiology Case Reports"],"original-title":[],"link":[{"URL":"http:\/\/radiologycases.radcoach.com\/index.php\/radiologycases\/article\/download\/1869\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/radiologycases.radcoach.com\/index.php\/radiologycases\/article\/download\/1869\/interactive","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/radiologycases.radcoach.com\/index.php\/radiologycases\/article\/download\/1869\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,25]],"date-time":"2023-09-25T06:49:15Z","timestamp":1695624555000},"score":1,"resource":{"primary":{"URL":"http:\/\/radiologycases.radcoach.com\/index.php\/radiologycases\/article\/view\/1869"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,4,19]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2015,4,29]]}},"URL":"https:\/\/doi.org\/10.3941\/jrcr.v9i4.1869","relation":{},"ISSN":["1943-0922"],"issn-type":[{"value":"1943-0922","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,4,19]]}}}
