Sonographic Appearance of a Solitary Intramuscular Cysticercosis: A Case Report

The development of antiparasitic drugs and public health strategies has reduced the prevalence of cysticercosis in South Korea. In contrast, the disease is still endemic in Southeast Asia. The influx of immigrants from endemic areas has been on the increase. We report the sonographic and pathological findings of cysticercosis that presented as an intramuscular solitary mass in a 27-year-old Philippine woman.

Benign Lesions with Posterior Acoustic Shadowing on Ultrasound: The Pathologic Correlation

A breast lesion with posterior acoustic shadowing is often encountered on sonography and this finding is generally accepted as a sign of malignancy. Although its detection is important for differentiating a malignant breast mass from a benign breast mass, posterior acoustic shadowing is the result of attenuation of the sound beam by a desmoplastic host response to breast cancer rather than the posterior acoustic shadowing being due to the tumor itself. Therefore, many breast conditions that contain fibrous elements also can induce some degree of acoustic shadowing. In this article, we present various benign breast lesions that display posterior acoustic shadowing and we discuss the radiologic findings along with the pathologic correlation.
