Upon asking about other symptoms, he mentions that he had a cough for the last 4 months which he attributes to his smoking. He says he had frequent nasal stuffiness and headaches over the last 3 months, for which he takes over-the-counter cold medications and analgesics. Over the last 2 months, he often felt that his face was mildly swollen, especially in the morning hours, but he did not consider it to be anything serious. No significant past medical history. He reports a 20-pack-year smoking history. His temperature is 36.8°C (98.4°F), pulse is 96/min, blood pressure is 108/78 mm Hg, and the respiratory rate is 24/min. On physical examination, auscultation of the chest reveals rhonchi and crepitus over the right lung. The remainder of the exam is unremarkable. A chest radiograph reveals a mass in the middle lobe of the right lung. Which of the following clinical signs would most likely be present in this patient?   (A) Bilateral pedal edema   (B) Distended veins over lower abdomen   (C) Papilledema   (D) Sensory loss over the ulnar aspect of right forearm and right hand
