Dirofilariasis is a rare disease in humans. We report here a case of a 48-year-old male who was diagnosed with pulmonary dirofilariasis in Korea. On chest radiographs, a coin lesion of 1 cm in diameter was shown. Although it looked like a benign inflammatory nodule, malignancy could not be excluded. So, the nodule was resected by video-assisted thoracic surgery. Pathologically, chronic granulomatous inflammation composed of coagulation necrosis with rim of fibrous tissues and granulations was seen. In the center of the necrotic nodules, a degenerating parasitic organism was found. The parasite had prominent internal cuticular ridges and thick cuticle, a well-developed muscle layer, an intestinal tube, and uterine tubules. The parasite was diagnosed as an immature female worm of Dirofilaria immitis. This is the second reported case of human pulmonary dirofilariasis in Korea.

대상 데이터
A 48-year-old male was referred to Seoul National University Hospital after a routine check-up at a local hospital due to abnormal findings seen in chest CT. The patient had no significant past medical history.
2). The parasite was a nematode larva and had prominent internal cuticular ridges and thick cuticle, a well-developed muscle layer, an intestinal tube, and uterine tubules. The diameter of the worm was approximately 240 µm.
성능/효과
The diameter of the worm was approximately 240 µm. Based on these morphologic features, the worm was identified as D. immitis, an immature female worm.
