Patients with a history of RYGB present a technical challenge for excluded gastric remnant gastrostomy placement. As the RYGB population increases and ages, obtaining and maintaining access to the gastric remnant is likely to become an important part of interventional radiology's role in the management of the bariatric patient.

Retroperitoneal malignant peripheral nerve sheath tumor (MPNST), a rare type of neurogenic tumor, was diagnosed in a 14-year-old girl with a history of neurofibromatosis type 1 (NF1). Immunochemistry demonstrated spindle cells positive for S-100 protein. The patient had multiple tumor recurrences and she was evaluated with serial F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET). A tumor in the right iliac wing showed increased FDG uptake on PET. FDG-PET played an important role in therapy planning and subsequent follow up. This case emphasizes the important role FDG-PET could play in the staging, restaging, and posttherapy follow up of MPNST.

Deep venous thrombosis and thromboembolism are significant health risks, with high rates of morbidity and mortality. Chronically ill and hospitalized patients, particularly those with cancer, have a high risk for developing these conditions. Mechanical inferior vena cava (IVC) filtration has been standard care for patients with these conditions in whom anticoagulation therapy is contraindicated or has failed. This article reviews caval filters and the current indications for using mechanical IVC filters, including retrievable versus permanent filters, focusing on their use in treating venous thromboembolism in cancer patients.

The authors describe various patterns of F-18 fluorodeoxyglucose (FDG) accumulation in the diaphragm and crura. They present 6 patients in whom incidental diaphragmatic and crural uptake of FDG was observed during positron emission tomography (PET). Hyperventilation is thought to be the potential underlying mechanism of this condition.
