Asymptomatic Liver Abscesses Mimicking Metastases in Patients after Whipple Surgery: Infectious Complications following Percutaneous Biopsy—A Report of Two Cases

We present two cases of hepatic abscesses that mimicked metastases in patients having undergone Whipple surgery. Both patients had similar imaging features on computed tomographic (CT) scan and ultrasound, and at the time of referral for biopsy neither patient was clinically suspected to have liver abscess. Both patients underwent biopsy of liver lesions and developed postprocedural infectious complications

Symptomatic Fluid Drainage: Peritoneovenous Shunt Placement

AbstractAscites causes significant discomfort and has negative impact on patient's quality of life. Medical therapies including dietary restriction and diuretics are successful in only 40 to 44% of patients with malignant ascites and repeated paracentesis only provides temporary symptomatic relief. Therefore, a more permanent solution is necessary. Indwelling catheters or peritoneovenous shunt placement can provide more permanent symptomatic relief and improve patients' quality of life. Unlike indwelling catheters, peritoneovenous shunts do not limit patients' life style and therefore should be offered as first option in patients who are good candidates. Denver shunt (CareFusion-BD Worldwide) is the current available peritoneovenous shunt. In this article, the indications, contraindications, technical aspects of shunt placement, and techniques to prevent postprocedure complications will be discussed.</jats:p

Hilar Biliary Obstruction: Malignant Masquerades

Biliary obstruction at the hepatic hilus is most often due to malignancy. Clinically, it can be very difficult to differentiate malignant from benign obstruction when a mass lesion is not evident on cross-sectional imaging. In this article, we describe three cases of benign biliary obstruction due to so-called malignant masquerades to familiarize the reader with the clinical, radiographic, and pathological features of these uncommon but important entities
