Processo supurativo focal do parênquima cerebral, do espaço epidural ou subdural intracraniano ou espinal e, menos comumente, do parênquima da medula espinal. O processo supurativo é mais comumente associado à infecção bacteriana e, ocasionalmente, à infecção fúngica, protozoária ou parasitária. Os abscessos cerebrais se desenvolvem mais comumente por disseminação a partir de um local infectado contíguo (ouvido, seios paranasais, células aéreas da mastoide, dentes), osteomielite craniofacial e após traumatismo cranioencefálico aberto ou procedimento neurocirúrgico prévio. A disseminação hematogênica de infecções pulmonares purulentas, endocardite bacteriana ou outros locais de infecção também pode causar abscesso cerebral. Pacientes com abscesso intracraniano apresentam combinações variáveis de cefaleia, estado mental alterado, déficits focais e convulsões. Febre pode estar presente. Pacientes com abscesso intraespinal apresentam graus variáveis de paraparesia ou quadriparesia, comprometimento sensorial abaixo do nível da lesão, função esfincteriana alterada e dor nas costas. O diagnóstico é feito por tomografia computadorizada ou ressonância nuclear magnética e pode ser confirmado por exame histológico e cultura do material do abscesso após drenagem neurocirúrgica. A punção lombar geralmente é contraindicada. | |||

A focal suppurative process of the brain parenchyma, the intracranial or spinal epidural or subdural space, and less commonly the spinal cord parenchyma. The suppurative process is most commonly associated with bacterial infection, and occasionally with fungal, protozoal, or parasitic infection. Brain abscesses develop most commonly by spread from a contiguous infected site (ear, paranasal sinuses, mastoid air cells, teeth), craniofacial osteomyelitis, and following open head trauma or previous neurosurgical procedure. Haematogenous spread from purulent pulmonary infections, bacterial endocarditis, or other sites of infection can also cause brain abscess. Patients with intracranial abscess present with variable combinations of headache, altered mental status, focal deficits, and seizures. Fever may be present. Patients with intraspinal abscess present with variable degrees of paraparesis or quadriparesis, sensory impairment below the level of the lesion, altered sphincter function, and back pain. The diagnosis is made by CT or MRI imaging, and may be confirmed by histological examination and culture of the abscess material following neurosurgical drainage. Lumbar puncture is usually contraindicated. | |||
