Bm-12 * cerebral infarction secondary to pulmonary vein compression and left atrial appendage tumor infiltration as the presenting sign of metastatic squamous cell carcinoma of the base of the tongue
CONCLUSION: Cardiac metastases are rare and non-myxomatous tumor embolization to the brain even rarer especially in the setting of cerebral infarction due to pulmonary vein thrombus. Here we describe a case of multiple acute cerebral infarctions appearing from a proximal source refractory to anticoagulation. Thromboembolism from the pulmonary vein and tumor embolization from cardiac metastases are the likely mechanisms for his clinical presentation and radiographic findings. This case demonstrates the complexity of multiple stroke etiologies in one patient and the importance of cardiac imaging in stroke evaluation, particu...

Portal venous air embolization.
Abstract To the Editor A 74-year-old lady was diagnosed with an inoperable gallbladder carcinoma with peritoneal deposits and acute cholangitis. As a palliative procedure, the patient was taken up for endoscopic retrograde cholangiopancreatography (ERCP) which was performed under conscious sedation with the patient placed in a semi-prone position. 7F-biliary stents were successfully placed in the bile duct, however, note was made of inadvertent air entry into the portal vein. Spot-radiograph taken with the patient in semi-prone position (Figure-1) reveals an iatrogenic pneumovenogram (arrows). The procedure was im...
