question: Hi I m 46 years old, female, with 58kg weight. 3 weeks ago I noticed a something protruding just below the bottom left rib. It is very obvious and clearly visible to the eye. The doctor did an exam and though she could clearly see it , she could not feel anything. I was sent to get a chest x-ray and an abdomen ultrasound. I have just received the report from these tests: Lungs, heart, and ribs are all clear. No focal lesions. However the ultrasound report states: The region of interest on the lower chest wall correlates with a lower rib chostochondral junction. No leasion is seen in this region. This is mildly asymmetrically more prominent compared with the right side of the same level. What does this mean? Do I need to be concerned? I m lost... Thank YOu
