Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries.

Epidural hematoma as seen on a CT scan with overlying skull fracture. Note the biconvex shaped collection of blood. There is also bruising with bleeding on the opposite side of the brain. Specialty: Neurosurgery, Neurology: Symptoms: Headache, confusion, paralysis [1] Usual onset: Rapid [2] Causes: Head injury, bleeding disorder, blood vessel ...
This is the primary cause of death among people who initially survive an explosion. [22] Unlike other mechanisms of injury in which pulmonary contusion is often found alongside other injuries, explosions can cause pulmonary contusion without damage to the chest wall. [15] In addition to blunt trauma, penetrating trauma can cause pulmonary ...
Any virus that can cause an upper respiratory illness can move into the lungs, causing pneumonia. ... elderly people who take a big fall can bruise their lungs, creating a pulmonary contusion (or ...
A fracture through the sella can lead to profuse blood aspiration. A common mechanism for transverse fractures is a sharp blow to the chin, such as a fall onto a hard surface. The impact energy transfers to the skull base via the mandibular rami and temporomandibular joints. The chin injury may appear minor, often just a small abrasion or ...
The contrast dye may not all go inside the vein at the cannula site, and if it extravasates, it may cause pain or bruising to the local area. [3] The scan involves radiation, which may increase the risk of future cancers by a very small amount, [3] or prove damaging to a pregnancy. [3] Additionally, the dye used can damage kidney function.

A bruise, also known as a contusion, is a type of hematoma of tissue, [3] the most common cause being capillaries damaged by trauma, causing localized bleeding that extravasates into the surrounding interstitial tissues. Most bruises occur close enough to the epidermis such that the bleeding causes a visible discoloration.
The diagnosis is generally clinical, with a fluctuant boggy mass developing over the scalp (especially over the occiput) with superficial skin bruising. The swelling develops gradually 12–72 hours after delivery, although it may be noted immediately after delivery in severe cases. Subgaleal hematoma growth is insidious, as it spreads across ...
