Subdiaphragmatic abscess due to penetration of a duodenal ulcer successfully treated with endoscopic transgastric drainage: a case report.

Background: Subdiaphragmatic abscesses are sometimes caused by intraabdominal infections. We report a case of endoscopic ultrasound-guided transgastric drainage.

Case Presentation: A 75-year-old Asian man was referred to our hospital for treatment for upper gastrointestinal bleeding.

Calcification and abscess formation around the catheter tip of a central venous access port: a case report.

Background: Thrombosis of the internal jugular vein occasionally occurs in association with long-term placement of a central venous catheter; however, such complications rarely involve calcification within the blood vessels. We report a case of calcification and abscess formation around a central venous catheter tip.

Case Presentation: Our patient was an 84-year-old Asian woman who developed a fever that had started approximately 5 months after the placement of a central venous catheter.
