To describe clinical and computed tomography (CT) findings of isolated dissection of the visceral arteries (IDVA). ⋯ Based on our observation, patients with IDVA can be managed conservatively when there are no signs indicating organ ischemia.

A 77-year-old woman who had been in the hospital suffering from a subarachnoid hemorrhage suddenly died after undergoing a cerebral aneurysmal operation. Postmortem whole-body computed tomography (CT) demonstrated multiple lung tumors with abnormal masses in the bronchus with no evidence of complications in the cranium. ⋯ Although a traditional autopsy was not performed, postmortem CT provided strong evidence for detecting the cause of death. In this case, postmortem CT played an important role in hospital risk management.

The aim of this study was to evaluate the efficacy of double arterial phase dynamic magnetic resonance imaging (MRI) with the sensitivity encoding technique (SENSE dynamic MRI) for detection of hypervascular hepatocellular carcinoma (HCC) in comparison with double arterial phase dynamic multidetector-row helical computed tomography (dynamic MDCT). ⋯ Double arterial phase SENSE dynamic MRI is as valuable as double arterial phase dynamic MDCT for detecting hypervascular HCCs.

Primary cardiac lymphoma is a rare, extremely aggressive malignancy. Early diagnosis and treatment is important for patient survival. We present a case of a 76-year-old woman admitted for worsening dyspnea caused by a large tumor in the right atrium. Magnetic resonance imaging and computed tomography clearly depicted the primary cardiac tumor, and histopathological study of the surgical specimen confirmed the diagnosis of diffuse large B-cell lymphoma.

Case Reports
Percutaneous translumbar inferior vena cava cannulation under computed tomography guidance.
Percutaneous translumbar inferior vena cava (IVC) cannulation is an alternative approach for central venous catheterization, but there have been sporadic reports of puncture-related complications. To avoid complications during IVC puncture, percutaneous translumbar IVC cannulation was performed under computed tomography (CT) guidance in addition to fluoroscopy in two patients. ⋯ A guidewire was inserted through the long elastor needle, and a catheter was placed over the guidewire. It was possible to perform central venous catheterization by percutaneous translumbar inferior vena cava cannulation under CT guidance.
