How Should A Discolored Bruise Under The Eye Be Diagnosed And Treated?
Very unlikely.
Detailed Answer:
Hi,
The period in which hemorrhage is likely to occur is during the first 24 hours, 8 hours at most. During that time even if there was an initial minor bleed the blood will clot and the bleed will stop. It is very unlikely for bleeding to occur afterwards, those cases you might have read about are usually patients with prior clotting issues favored by taking anticoagulant medication, blood or liver conditions etc. CT is very sensitive in detecting blood, I don't think MRI is needed for that purpose.
The bump and bruise you see, while not pretty and I imagine worrying to you are not related to the possibility of having a brain bleed. No matter how soon or late they heal they are outside the skull, doesn't indicate anything regarding brain bleeds. Symptoms to watch for would be seizures, speech issues, double vision or vision loss, weakness or numbness of the limbs on one side, confusion or changes in behavior, increasing headache. Only those would prompt for another evaluation and possibly brain imaging. Otherwise given the fact that 2 days have almost gone by and normal findings on doctor's exam an CT I do not think there is any cause for alarm.
I remain at your disposal for other questions.
