      We report a 30-year-old patient who was involved in a high-velocity road traffic accident and developed a left-sided hemiparesis, which was noted in the post-operative period following bilateral femoral intramedullary nailing. CT scanning of the brain revealed infarcts in the right frontal and parietal lobes in the distribution of the right middle cerebral artery. CT angiography showed occlusion of the right internal carotid artery consistent with internal carotid artery dissection. He was anticoagulated and nine months later was able to walk independently. An awareness of this injury is needed to diagnose blunt trauma to the internal carotid artery. Even in the absence of obvious neck trauma, carotid artery dissection should be suspected in patients with a neurological deficit in the peri-operative period.
    • Isolated pancreatic metastases from a bronchogenic small cell carcinoma.

      We describe the case of a 60 year old female smoker who presented with a three month history of weight loss (14 Kg), generalized abdominal discomfort and malaise. Chest radiography demonstrated a mass projected inferior to the hilum of the right lung. Computed Tomography of thorax confirmed a lobulated lesion in the right infrahilar region and subsequent staging abdominal CT demonstrated a low density lesion in the neck of the pancreas. Percutaneous Ultrasound guided pancreatic biopsy was performed, histology of which demonstrated pancreatic tissue containing a highly necrotic small cell undifferentiated carcinoma consistent with metastatic small cell carcinoma of the bronchus.
