Ultrasonographic Findings of Subcutaneous and Muscular Sparganosis

caused by the larval form of an animal tapeworm of the genus Spirometra (1). The definite host is a carnivorous mammal, such as a dog or cat and intermediate hosts are a wide spectrum of vertebrates that include amphibians, reptiles, birds and mammals (2). Humans are usually a paratenic host (3). The route of infection is ingestion of raw meat of snakes or frogs, or drinking contaminated water (3).
