Cranial infections can be seen clinically as intracranial, cranial and extracranial infections. Cranial infections are mainly caused by viruses, bacteria, tuberculosis or fungi that cause infection of the dura mater, soft meninges and brain parenchyma, resulting in symptoms of central nervous system damage, which can be accompanied by fever, headache, nausea, vomiting, and in severe cases, impaired consciousness. Some patients may have seizures. Cranial infections are usually caused by trauma, including fungal, bacterial or tetanus infections, and scalp infections are mainly caused by bruises or trauma. If the infection is intracranial, a lumbar puncture should be performed to identify the causative organism and give treatment. If the infection is cranial or scalp, culture should be performed and give treatment to the causative organism.
