Standing waves are a phenomenon of uncertain etiology seen on imaging. We present the first case demonstrating standing waves on computed tomography angiography in multiple vessels in a single patient with imaging evidence of resolution in some of the vessels. Our case further supports the literature that standing waves are a physiologic phenomenon, likely because of flow mechanics, rather than modality.

A significant proportion of patients with localized pancreatic cancer will have liver lesions identified at the time of diagnosis and most of these lesions will have indeterminate characteristics. A classification system which further stratifies indeterminate liver lesions by malignant potential can assist clinicians in determining optimal treatment plan and is associated with a high negative predictive value.

Bilateral multiple renal abscesses have been found in individuals with predisposing factors, but are rare in people who are otherwise healthy. This case report shows that ultrasound plays a key role in management of renal abscesses with a key advantage over CT when combined with ultrasound-guided aspiration of the abscess. Early diagnosis using ultrasound gives a higher probability that antibiotic treatment will be all that is required, thus reducing the risk of rupture and surgery.
