Pulmonary dirofilariasis in man is becoming a well-recongnized entity. Its pathogenesis and histopathologenical picture have been well characterized but the preoperative diagnosis still remains a challenge. The roentgenographic picture, usually described as a "coin lesion," is nonspecific and easily mistaken for other inflammatory and neoplastic nodules. Forty-seven clinical instances of pulmonary dirofilariais have been reported in the literature, with most of them in the last two decades. Considering the entire clinical picture, a strong suspicion can be based on serological studies, thus improving the possibilities of a correct preoperative diagnosis.
