We present a rare case of a solitary cysticercal cyst that involved the anterior abdominal wall musculature and was diagnosed with sonography. Sonograms revealed a small, well-defined, elliptical cystic lesion with an eccentric hyperechoic area within it. An eccentric, echogenic, pedunculated structure was seen within the cystic area of the lesion. No calcification was apparent. The lesion was surrounded by inflammation in the muscle. Hypervascularity in the surrounding muscle was noted on color Doppler imaging. If lesions with similar morphologic characteristics are encountered in the musculature or subcutaneous tissues during sonographic examination for another condition, one should suspect cysticercosis., (Copyright 2001 John Wiley & Sons, Inc.)

Eleven Small-Ear-Miniature pigs, 1 Landrace Small-Ear-Miniature pig, and 1 monkey (Macaca cyclopis) were infected experimentally with eggs of Taenia saginata asiatica. They were found to harbor cysticerci on the liver surface, each with a thin, whitish fiber connecting to another location in the same lobe, or to other lobes of the liver; some were also connected individually to the diaphragm, abdominal muscles, and gall bladder with a short, thin fiber. Moreover, they also harbored extrahepatic cysticerci. Most of these were observed on the omentum and in the peritoneal cavity, except for some suspended individually in the abdominal cavity by a long, thin, whitish fiber. The origin of the extrahepatic cysticerci and whitish fibers is probably from the surface of the liver of the host.
