The postmortem changes revealed prescience of peticial hemorrhage beneath capsule and parenchyma of the liver with large number of larval cysts attached at the liver, peritoneum and diaphragm and others found within the peritoneal cavity. Histopatholgical changes of the liver tissue were showed necrosis of hepatic cells with highly infiltration of inflammatory cells especially lymphocytes around the portal area in addition to deposit of haemosidrin pigment. Larval stage reached to adult stage after 45 days in the final host (dogs) and the morph metric study was indicated that the species of the parasite is Taenia pisiformis.
