83
Subdural Hematoma (SDH): Anatomical Location:
accumulation of venous blood located between the dura mater and the arachnoid membrane within the subdural space, conforming to the contour of the inner table of the cranium. These hematomas can extend into the interhemispheric or tentorial subdural spaces, spreading diffusely and crossing suture lines, but are limited by dural reflections such as the falx cerebri. This condition typically arises from the rupture of bridging veins, often due to head trauma caused by impact with a stationary object. However, injuries involving high-speed acceleration or deceleration can also lead to the tearing of veins between the cerebral cortex and the dural veins.
84
Subdural Hematoma (SDH):
This condition typically arises from the rupture of bridging veins, often due to head trauma caused by impact with a stationary object. However, injuries involving high-speed acceleration or deceleration can also lead to the tearing of veins between the cerebral cortex and the dural veins.
85
Subdural Hematoma (SDH):Shape/appearance on MRI:
crescent-shaped mass
86
Epidural Hematoma (EDH): Anatomical Location:
EDH occurs in the epidural space, filling with blood due to head trauma. It is situated between the dura mater and the cranium, typically in the temporoparietal region, often involving arterial injury (commonly the middle meningeal artery). Less common venous epidural hematomas usually occur in the posterior fossa or near the occipital lobes.
87
Epidural Hematoma (EDH): Shape/appearance on MRI:
Typically, biconvex and lens-shaped, confined by suture lines due to the dura's adherence
