Traumatic injury to the adrenal gland can be graded using the Adrenal Organ Injury Scale,
Type of Injury
Involvement
Grade
contusion
I
laceration
involving only cortex (< 2 cm)
II
extending into medulla (>= 2 cm)
III
parenchymal destruction
> 50% but subtotal
IV
total, including massive intraparenchymal hemorrhage
V
avulsion from blood supply
V
where:
• I am unsure what the meaning of the laceration measurement in centimeters is. The cortex is usually only a few millimeters thick, while the entire adrenal gland is only a couple centimeters in any one dimension.
• Parenchymal destruction < 50% is not listed as an option.
The final grade for bilateral injuries is increased by 1 up to grade V.
• I am assuming that grade IV can be increased to grade V but grade V is not increased to grade VI.
