Intracranial infection

Introduction Intracranial infection is one of the complications of traumatic brain injury. There are foreign objects in the skull, including caps, hair, skin, skull fragments, bullets or shrapnel, and other weapons that cause injury. Such trauma is easy to be complicated by intracranial infection, intracranial hematoma, acute brain swelling, increased intracranial pressure, acute cerebral edema and late epilepsy, etc., which can easily lead to the death of the wounded. It is necessary to perform early debridement surgery and close. The cranial cavity transforms the open injury into a closed injury. Intracranial infections in the field of neurosurgery are often caused by trauma and surgery. Blood-borne abscesses, parasitic diseases, granulomas, and tuberculosis are also common. It often leads to mental disorders and requires timely treatment.

Cause

Caused by an intracranial injury. Intracranial infections mainly include meningitis, encephalitis, and brain abscess. The pathogen may be bacteria, viruses, parasites, mycoplasma, chlamydia, mold, rickettsia, and the like.

1. Interview: Ask about the time of injury, the type of injury, whether the wound has cerebrospinal fluid or brain tissue, and what kind of treatment.

2, head wound examination: should be carefully examined the size and shape of the wound, with or without active bleeding, with or without broken bone fragments, brain tissue or cerebrospinal fluid outflow. If the wound has cerebrospinal fluid or brain tissue outflow, it is diagnosed as an open brain injury.

3, disturbance of consciousness: depending on the location and extent of brain injury, localized open injury and important structure of the brain or patients without intracranial hypertension, usually unconscious disorder, and extensive brain injury, brain stem or hypothalamic injury, combined with intracranial hematoma or Brain edema caused by intracranial hypertension, there may be varying degrees of disturbance of consciousness.

4, CT scan of the skull for the diagnosis of intracranial hematoma, brain contusion, subarachnoid hemorrhage, midline shift, ventricular size, intracranial foreign body and skull fracture can also be displayed, but not as good as X-ray film. Have important reference value.

Differential diagnosis

Mainly have dural sinus recessive embolism, diffuse glioma, cancerous meningitis, granulomatous meningitis and microcephalic malformations. The main features of the above lesions can cause headache, optic disc edema, and severe intracranial pressure, but no imaging lesions can be seen in imaging examination, and there are no other localized signs in neurological examination.
