Star Subdural hematoma

Rupture of bridging veins. Slow venous bleeding less pressure = hematoma develops over time.
Seen in elderly individuals, alcoholics, blunt trauma, shaken baby syndrome
predisposing factors- brain atrophy shaking, whiplash
Crescent shaped hemorrhage that crosses suture lines.
Midline shift.
Gyri are preserved, since pressure is distributed equally.
Cannot cross falx, tentorium

Oohh, Quetions on usmle is with a key word you know,
Try to look at symtoms which can differentiate, for example : if is a worst headache ever had, you know this is subarachnoid..

If tell you thing that lead to see shaken baby syndrome, abused child, this will be subdural hemorrhage of course

Head trauma, like in alcoholics will lead to most commonly damage temporal area, which will lead to rupture of the MCA...

In this style you can make some associations...

And of course images from CT,:
Crescent shaped, along th skull subdural

Biconcave, like just near the trauma>>>>> epidural

And if you see lacunar, small, in different zones of brain, or in that where most commonly ruture aneurysms of ACA and PCM... Subarachoid will be....

Anytime you can do a lot of quetions for one topic, looks a tens to hudred pictures but you will see that moment when you catch this, you cag run around one image a couple times, read some explanation about this, and when you will return again to same topics you will recognise rapidly, and will fix information...

You must understand what happening in picture, when you know mechanism, patho, you recongnise very fast what happening
You can skip sometime any hard for you topics, and just familiarise with them, after you will come back and will work hardly ...
