In a batch of 250 rabbits, whitish spots were observed in two livers, measuring from 0.2 to 0.3 cm in diameter, in the capsular surface, mostly on the diaphragmatic side. The lesions did not extend into the liver parenchyma.

Histopathological examination showed areas of granulomatous inflammation with abundant epithelioid macrophages surrounding a necrotic center with presence of multinucleated giants cells. These lesions involved the liver capsule and the superficial parenchyma and are strongly suggestive of parasitic migration tracts of Cysticercus pisiformis, the larval stage of Taenia pisiformis which is commonly found in rabbits. The final hosts are dogs and cats.
