Pulmonary Dirofilariasis and Transitional Cell Carcinoma

Abstract

• Pulmonary dirofilariasis occurred in a 79-year-old man with known transitional cell carcinoma. Bilateral lung nodules suggesting metastatic carcinoma were resected and subsequently identified as being caused by<i>Dirofilaria immitis</i>. The typical features of human dirofilarial infection are reviewed and contrasted with the unusual clinical findings in this patient. (<i>Arch Intern Med</i>1983;143:1259-1260)
