Learning objectives: The purpose of our educational exhibit is to: illustrate the normal anatomy and normal sonographic appearance of the abdominal wall; describe a differential diagnosis for evaluating the masses found in the abdominal wall; demonstrate the sonographic findings associated with different abdom[...]

Background: Abdominal wall masses are  often palpable and have a nonspecific sonographic appearance. However, if close attention is paid to the clinical history, location of the lesion and the sonographic appearance the differential can be narrowed down significantly. It is critial to understand the n[...]

Findings and procedure details:

Conclusion: •Abdomen wall masses have non-specific sonographic appearance.   •Differentiate hernia, cystic and solid masses.   •US-guidance for tissue sampling of indeterminate lesions.   •High frequency transducers can help to better characterize the echo pattern.   •Clues for etiology may [...]
