Case ReportsBilateral breast enlargement: an unusual presentation of superior vena cava obstruction in a hemodialysis patient with fibrosing mediastinitis.
A 67-year-old woman with end-stage renal disease presented with profound edema of both breasts. The presence of a patent hemodialysis basilic transposition fistula and superior vena cava obstruction (SVC), due to fibrosing mediastinitis, was demonstrated by the use of fistulography. Endovascular treatment with a balloon and stent caused immediate resolution of the breast edema.

MR-guided freehand biopsy of liver lesions with fast continuous imaging using a 1.0-T open MRI scanner: experience in 50 patients.
The purpose of this study was to assess a new open system with a field-strength of 1.0 T for the feasibility of liver biopsy using the freehand technique with fast continuous imaging. Fifty patients with focal liver lesions measuring 5 to 30 mm in diameter were included in the study. Guidance and monitoring was performed using a 1.0-T open magnetic resonance (MR) scanner (Panorama HFO; Philips Healthcare, Best, The Netherlands). ⋯ No major complications were recorded. MR guidance with the new 1-T open system must be considered an attractive alternative for liver punction. An interface for dynamic imaging of needle guidance and T1W-GRE imaging with administration of Gd-EOB-DTPA for contrast enhancement allows the pinpoint puncture of liver lesions.

Case ReportsChylous ascites: a rare complication of thoracic duct embolization for chylothorax.
Thoracic duct embolization represents a safe and effective method to treat postsurgical chylothorax. Complications of this procedure are rare despite transabdominal puncture of lymphatic channels for thoracic duct access, and chylous ascites is unreported. Herein, we describe a case of chylous ascites formation after lymphatic puncture and attempted cannulation. Our management approach is also discussed.

Letter Case ReportsIntramural dissection of the renal collecting system during percutaneous nephrostomy: computed tomography findings of a rare complication.
Intramural dissection of the renal collecting system during percutaneous nephrostomy (PCN) is a rare complication that can be challenging to diagnose. In this report, we describe the computed tomography (CT) and fluoroscopic findings of urothelial dissection during CT-guided PCN in a 65-year old patient with an obstructed congenital solitary left kidney due to an urinary bladder carcinoma. To our knowledge, CT findings of urothelial dissection have not yet been described.
