Cerebral contusion Cord Blood

Cerebral contusion Cord Blood

*Characteristics of Cerebral contusion

● Commonest form of traumatic intra-axial injury.

● Contusions occur at the frontal and temporal lobes.

● Injury produced by damage to parenchymal blood vessels leading to petechial haemorrhage and oedema.

● Contusions develop in surface grey matter tapering into white matter.

● Cerebral contusions are also produced secondary to depressed skull fractures and are associated with other intracranial injuries.

 

Clinical features Cord Blood

•Usually associated with a brief loss of consciousness and Confusion .

•Focal neurological deficit can occur if contusions arise near the sensorimotor cortex.

•Beware of the elderly patients, alcoholics and patients taking anticoagulants as they are at increased risk of haemorrhage.

Radiological features

1. Non-contrast computed tomography (CT) useful in the early posttraumatic period.

2. Magnetic resonance imaging (MRI) is the best modality for demonstration of oedema and contusion distribution.

•Contusions are seen as multiple focal areas of low or mixed attenuation intermixed with tiny areas of increased density representing petechial haemorrhage.

•Cerebral contusions in both frontal lobes.

•The adjacent low density represents local oedema.
