Sonography of Abdominal Wall Masses and Masslike Lesions

Sonography is usually regarded as a first‐line imaging modality for masses and masslike lesions in the abdominal wall. A dynamic study focusing on a painful area or palpable mass and the possibility of ultrasound‐guided aspiration or biopsy are the major advantages of sonography. On the other hand, cross‐sectional imaging clearly shows anatomy of the abdominal wall; thereby, it is valuable for diagnosing and evaluating the extent of diseases. Cross‐sectional imaging can help differentiate neoplastic lesions from non‐neoplastic lesions. This pictorial essay focuses on sonographic findings of abdominal wall lesions compared with computed tomographic and magnetic resonance imaging findings.
