Q: Recently an x-ray of the chest shows prominent right hilum as compared to the left hilum. Radiologist has commented as follows: probably vascular in nature. Is this abnormal? If so, what problems can it cause? What should I do about it?

A:A prominent hilum refers to an apparent enlargement of the root of the lung. This may be a normal variation or consequent to a disease process. This can be sorted out in the perspective of the clinical picture (symptoms and signs), appropriate laboratory tests and if necessary a CT scan. It would be in order to consult the Family Physician or a Pulmonologist (chest/lung specialist).
