Intracranial Hemorrhage

. . When faced with analyzing an unknown CT head, I advise you to do the following :

1…..Remember that the normal CT head is symmetrical ( except for the sagittal view ).
2…..If you see an abnormality, note its density and suggest the differential diagnosis of tissue such as : normal variant, malrotation, tumor benign calcifications, fresh blood, old blood, old infarcted tissue, recent infarcted tissue CSF& others Narrowing down of the differential diagnosis will be possible with clinical correlation, e.g. trauma, sudden development of hemiparesis, sudden onset headache, gradual development of symptoms, etc.
Don’t forget to check and see if the patient has a previous CT head—– comparison with the old CT will obviously aid you in your conclusion and treatment mode .
3…..If you believe the lesion is an acute hemorrhage, they will usually fall into four distinct categories : as follows ( Don’t forget to measure the Hounsfield Unit of the lesion—————— fresh blood is approximately + 40 )
    A…..Intracerebral Hemorrhage.
    B…..Acute Subarachnoid Hemorrhage.
    C…..Acute Subdural Hemorrhage.
    D…..Acute Epidural Hemorrhage.

Over the next series of windows I will focus on the intracranial bleeds as listed above with the goal of —
a… a bleed present?
b… the bleed A, B, C or D as listed above?
I will outline the salient feature of each one for recognition purposes. Please click on
