The MRI showed a lesion with a size of 180x100x75 mm consisting of cystic components within the right vastus lateralis muscle (Fig. 1). According to the WHO-IWGE classification, the grade of CE appearance changed from CE2 to CE3b after albendazole treatment (Fig. 1).

In the macroscopic examination of the removed cyst, daughter cysts were seen and it was found that the hydatid sand structure was denser and more caseified than normal (Fig. 2).

The scolex structures were observed in the material sent from the liver, but not in the specimen sent from muscular tissue after the use of albendazole (Fig. 3).
