Bilateral adrenal gland hyperenhancement or intense adrenal enhancement may be a feature of hypotension and forms part of the CT hypoperfusion complex.
Adrenal gland hyperenhancement has been described in paediatric and small adult series or individual cases of haemorrhagic shock, pancreatitis, sepsis and trauma 1-3 but has not been demonstrated in larger series of adults patients with traumatic hypoperfusion 4.
- acute adrenal haemorrhage: more commonly right-sided and unilateral with an enlarged adrenal gland and associated changes in the periadrenal fat 2
