Macroscopic and microscopic findings of the resected specimen. The resected liver sample included a white nodule of 12 mm in diameter with a regular border macroscopically. A tiny pinhole was seen within the nodule (upper left, black arrow). Roupe finding showed epithelioid granuloma with central necrosis in the normal liver tissue (upper right, original magnification × 0.4). Within the central necrosis, a small hole which bears an exogeneous material was recognizable (lower left, brack arrow, original magnification × 2). Axial slice of the larva surrounded by epithelioid granuloma with infiltration of inflammatory cells such as monocytes and eosinophils. The larva body had collapsed, but the specific Y-shaped lateral cord was recognizable (lower right, black arrows, original magnification × 20)
