Presentation may be subtle; people with mild contusion may have no symptoms at all.
"If you suffer a mild contusion, you would have pain and possibly bruising, and the treatment would be rest, elevation, and ice.
A computed tomography (CT) (Fig. 1a) performed on admission showed a mild contusion and laceration in the bilateral frontal cortex.
Physical examination and computed tomography (CT) on admission showed right isolated ptosis and mild contusion and laceration in the bilateral frontal cortex.
Sixteen hours after trauma, the median values (range) of sTREM-1 levels in BAL samples were 113 pg/ml (56 to 1,169 pg/ml) in the group with no contusion, 119 pg/ml (62 to 383 pg/ml) in the group with mild contusion, 258 pg/ml (62 to 1,332 pg/ml) in the group with moderate contusion and 299 pg/ml (68 to 1,929 pg/ml) in the group with severe contusion.
An unexpected observation in rats has previously been reported (Lee et al., 2005): rats with mild contusion injury, and thus fairly good functional recovery, display a decrease in the rate depression of the H-reflex, i.e. becomes more abnormal between the 1st and the 8th post-operative weeks.
Forty hours after trauma, the median values (range) of sTREM-1 levels in BAL samples were 217 pg/ml (62 to 1,384 pg/ml) in the group with no contusion, 339 pg/ml (82 to 819 pg/ml) in the group with mild contusion, 459 pg/ml (129 to 1,417 pg/ml) in the group with moderate contusion and 2,184 pg/ml (142 to 5,715 pg/ml) in the group with severe contusion.
While the long-term effects of subtle hypoxia on brain tissue are not fully understood, it is becoming increasingly clear that oxidative stress may trigger neuropathological processes both local and distal to the site of mild brain contusion, effects which may only manifest themselves months to years later [ 31].
The severity ranges from mild to deadly small contusions may have little or no impact on the patient's health yet pulmonary contusion is the most common type of potentially lethal chest trauma.
Laperriere had a brain contusion, a mild concussion and a cut that needed 70 stitches to close.
