A 56-year-old Japanese woman underwent partial hepatectomy for intrahepatic cystic masses. Before operation, the patient had been diagnosed as liver abscess due to Ascaris infection serologically. The excised hepatic lesions consisted of encapsulated old abscesses, with a few calcified parasitic ova and numerous Charcot-Leiden's crystals microscopically seen in necrotic exudate. However, no parasitic worms were found in the cystic cavity. The eggs in the tissues were indistinguishable from other helminthic ova morphologically, but stained positively for Ascaris antigens by the indirect immunoperoxidase method. The results indicate that the serologic diagnosis of intrahepatic ascariasis may be feasible, practical, and reliable.
一名56岁的日本女性因肝内囊性肿物接受了部分肝切除术。术前，患者经血清学诊断为蛔虫感染所致肝脓肿。切除的肝脏病变由包膜包裹的陈旧性脓肿组成，在坏死渗出物中显微镜下可见少量钙化的寄生虫卵和大量夏科-莱登结晶。然而，在囊腔内未发现寄生虫。组织中的虫卵在形态上与其他蠕虫虫卵无法区分，但通过间接免疫过氧化物酶法对蛔虫抗原染色呈阳性。结果表明，肝内蛔虫病的血清学诊断可能是可行、实用且可靠的。
