[Two surgical cases of pulmonary dirofilariasis]

Two surgical cases of pulmonary dilofilariasis (women aged 80 and 54 years old) were reported. They, who had no history of keeping dogs, were admitted to our hospital with complaining of cough and coin lesion on chest X-ray. On investigation, it was difficult to distinguish between pulmonary dilofilariasis and lung cancer. Wedge resection was performed by video-assisted thoracic surgery (VATS), and a definite diagnosis of pulmonary dilofilariasis was made. Nodes 2-3 cm in diameter are formed beneath the pleura in many cases of pulmonary dilofilariasis. Therefore, VATS is useful owing to its minimal invasiveness.
