A 4.5-cm male Dirofilaria indistinguishable from D. immitis was removed from the tip of the index finger of an 18-year-old farmer in Costa Rica. The case is reminiscent of a report of a larger (9-cm) but otherwise similar Dirofilaria, identified as D. spectans, a heartworm of otters, causing Raynaud's syndrome by occluding an artery of the fifth finger of a farm woman in Brazil. As in the present case, the worm was removed from a painful papule on the volar surface at the extreme tip of the affected finger.
在哥斯达黎加，从一名18岁农民的食指指尖取出了一条4.5厘米长的雄虫，该虫与犬恶丝虫无法区分。这一病例让人想起一份报告，报告中提到一条更大（9厘米）但在其他方面相似的恶丝虫，被鉴定为水獭心丝虫的斯氏恶丝虫，它通过阻塞巴西一名农场女性第五指的动脉而导致雷诺氏综合征。与本病例一样，该虫是从患指最末端掌面的一个疼痛丘疹中取出的。
