Sonographic diagnosis of a solitary intramuscular cysticercal cyst.

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.
