Luftsichel sign

Seen in some cases of left upper lobe collapse, it is due to hyperinflation of apical segment of left lower lobe, interposing itself between the mediastinum and the collapsed left upper lobe.

The right lung seemed to be hyperinflated as well. Left lung volume is smaller. Mediastinum shift is observed.

Kerley Lines

Source of information: Catscanman.net

Chest Radiography: AP view

Kerley B lines (red arrows) are thickened horizontal linear opacities in the subpleural region, which meet the pleura at right angles.

Kerley A lines (yellow arrows) are longer lines coursing diagonally toward the hila in the inner half of the lungs. 

Other findings:

1) Pulmonary venous congestions : visible at first intercostal space, vessels are more than 3mm in diameter.

2) Loss of clarity of major vessels: Perihilar haze. Undefined outline of vessels 

This is due to leakage of fluid  into the interstitium from pulmonary veins. Lymphatics converge to hilar and absorb fluid.

3) Pleural Effusion may be visible.

Medschool can never give enough lectures on radiology.
In this website you can find intepretations of chest x-rays, and some CT scans.
Watch all the videos and you will find yourself more confident the next time you encounter an x ray.

Awesome site with lectures, with immunology, bacteriology and so forth.
If you are already in your clinical years I suggest visiting geriatric medicine.
Certain schools did not give enough emphasis on echocardiography, hence it's great to watch the clinical cardiology videos too.
Great for USMLE preparation. :)

The chosen path.

In our journey in pursuing medicine, we realised that medicine was not like what we imagined at all. If anything, it is only worse. Some may even say that doctors are glorified slaves.

But are we?
Will all medical students eventually become a competent doctor at the end of the day if we graduate? Or is it just another license to kill?

Three years into my medical education, and I still haven't quite figure out the answer.
But what I do know is, the more we know, the safer we will be.

Here is a place to share the knowledge that I  have gained, points of views, and also awesome websites to learn more things.

Hopefully we can be closer to ideal.
