Primary malignant melanoma of the esophagus is a rare but aggressive tumor that accounts for less than 0.1-0.2% of all esophageal malignancies. The aim of this study was to report a case of primary malignant melanoma of the esophagus in a 72-year-old woman. The diagnosis was histologically proven, but the patient died despite extensive surgical resection.

Cerebral dural sinus thrombosis remains an uneasy clinical diagnosis because it may present with a spectrum of nonspecific manifestations. CT and MR findings have been described to help recognize this entity. We report here a case with different stages of thrombosed superior sagittal and right transverse dural sinuses demonstrated by CT and MR imaging.

In a phantom and in 37 patients, a simple laser guidance system for computed tomography (CT)-guided procedures used the software program of the CT scanner and a laser beam mounted on the CT gantry without need for additional software or components. The skin entry point and angulation of the target path were determined. Then the system projected the desired needle path (including compound angulation), allowing accurate needle placement in all cases, even in small lesions.
