We report herein on a case strongly suspected of being pulmonary toxocariasis. A 22-year-old Indonesian man referred to our hospital presented with abnormal chest shadows upon medical examination. He had no symptoms. He did not have any pets nor did he eat raw beef or chicken. Hematological examination revealed eosinophilia and elevation of IgE. Chest computed tomography revealed 3 pulmonary nodules with the halo sign. We suspected a parasite infection and performed antiparasite antibody testing. Ascaris suum was slightly positive on the screening test. As specificantibody against the larval excretory-secretory products of Toxocara canis, measured at the National Institute of Infectious Diseases, was positive (level 3 up to 8). Subsequently, the abnormal chest shadows disappeared. However, two months later, 2 pulmonary nodules with the halo sign reappeared in other places. Diagnostic therapy with albendazole was performed for 8 weeks. Mild hepatic impairment emerged during therapy, but it was within the allowed range. Thereafter,the results improved for the imaging findings, eosinophilia, serum IgE level, and specific antibody.The antibody level became negative two months after the treatment had ended. We should consider toxocariasis in the differential diagnosis of migratory nodular shadows with the halo sign on chest computed tomography,and immunoserological testing is useful for the diagnosis.

Human T-lymphotropic virus type I (HTLV-I) 抗体価が高値を示し, 多発結節性陰影を呈したT細胞性リンパ腫の1例を経験した. 症例は42歳, 男性. 千葉県出身. 昭和63年6月に胆嚢摘出術後, 発熱が持続したため当院受診, HTLV-I抗体価の高値を指摘された. 約8ヵ月後, 胸部X線上多発結節性陰影が出現, 開胸肺生検にてT細胞性リンパ腫と診断された. 文献を検索し得た限りでは肺原発のT細胞性リンパ腫において, 多発結節性陰影を呈した報告例は1例のみであった. また本症例の肺病変はHTLV-I感染との間に関連性があり, Adult T-cell lymphoma の初発の病変と考えられたので報告する.
