The lesion is located in the right thorax just lateral to the mid-saggital plane

Oh, my!

To understand the location of a lesion in the right thorax that is lateral to the mid-sagittal plane, let's break it down step by step:

1. Locate the mid-sagittal plane:
- The mid-sagittal plane is an imaginary vertical line that divides the body into equal right and left halves. It runs from the top of the head down to the bottom of the torso.
- Imagine yourself looking at the body from the front. The mid-sagittal plane would be the line directly in the middle, dividing the body into two equal halves.

2. Identify the right thorax:
- The thorax refers to the upper part of the trunk, also known as the chest.
- To find the right thorax, imagine yourself facing the person or body you are examining. The right side of their chest will be on your left side.

3. Determine the location of the lesion:
- "Lateral to the mid-sagittal plane" means the lesion is situated to the side of the mid-sagittal plane.
- In this case, the lesion is specifically on the right side of the thorax.

Putting it all together, the lesion is located on the right side of the chest, to the side of the imaginary vertical line that divides the body into equal right and left halves.
