Case ReportsNeonatal dural venous sinus thrombosis associated with central venous catheterization: CT and MR studies.
We report a case of extensive thrombosis of dural venous sinuses associated with placement of a central venous catheter in the jugular vein. Cases such as this one, though uncommon, underscore a potentially devastating complication associated with central venous catheterization and emphasize caution in catheter placement particularly in neonates.

Acute temporal lobe herniation is a serious complication that may occur with an expanding temporal or parietal lobe mass. Temporal lobe herniation may produce further damage to intracranial structures due to compression or vascular compromise. Differentiation of clinical and imaging abnormalities due to the primary lesion from those related to temporal lobe herniation is essential for proper diagnosis and management. The CT and magnetic resonance findings in a 2 1/2-year-old child who survived severe temporal lobe herniation are reported.

A 32-year-old man with Behçet syndrome presented with hemoptysis and abnormal chest radiography. A 3 cm opacity was present in the apical posterior segment of the left upper lobe and the hila were enlarged with lobulated contours. Computed tomography revealed bilateral pulmonary artery aneurysms, a complication of Behçet syndrome. Computed tomography is recommended for the evaluation of patients with Behçet syndrome who have abnormal chest radiography.

Case ReportsCT demonstration of massive cerebral air embolism from pulmonary barotrauma due to cardiopulmonary resuscitation.
A 77-year-old man with loss of consciousness, circulatory collapse, and apnea caused by myocardial infarction underwent cardiopulmonary resuscitation with intratracheal intubation and manual bag ventilation. Computed tomography of the head demonstrated massive air embolism in the entire cerebral circulation. The patient was diagnosed as brain dead the next day. Demonstration of massive cerebral air embolism on head CT is presented.

Case ReportsComputed tomography of mediastinal hematoma secondary to unusual esophageal laceration: a Boerhaave variant.
The Boerhaave syndrome is classically considered a panmural perforation of the distal esophagus secondary to forced vomiting or retching. A variant of the syndrome is described in which only the outer longitudinal muscle layer of the esophagus was torn, and in this case most of the usual radiological findings were absent. The clinical, radiological, and surgical findings are discussed.
