Imaging findings of hepatic lesions of visceral larva migrans are reported. A 44-year-old man presented with chills, eruptions, marked leukocytosis (31,400/microlitter), and eosinophilia (eosinophil, 72%). Multiple liver nodules were detected as low-density lesions on computed tomography (CT). They were visualized as high signal intensity lesions on T2-weighted, and as low signal intensity lesions on T1-weighted magnetic resonance imaging (MRI). The patient was diagnosed as having visceral larva migrans due to Toxocara canis, by Toxocara immnoserological test. After antihelmintic therapy, multiple liver nodules disappeared on CT. We consider that the differential diagnosis of multiple liver nodules should include visceral larva migrans.
报告了内脏幼虫移行症肝脏病变的影像学表现。一名44岁男性出现寒战、皮疹、明显的白细胞增多（31400/微升）和嗜酸性粒细胞增多（嗜酸性粒细胞，72%）。计算机断层扫描（CT）显示肝脏有多个低密度结节性病变。在T2加权磁共振成像（MRI）上，这些病变表现为高信号强度，而在T1加权MRI上则表现为低信号强度。通过犬弓首蛔虫免疫血清学检测，该患者被诊断为犬弓首蛔虫引起的内脏幼虫移行症。抗蠕虫治疗后，CT上肝脏的多个结节消失。我们认为，肝脏多发结节的鉴别诊断应包括内脏幼虫移行症。
