What is the pathophysiology of brain abscess?

Pathogenesis of brain abscess. Brain abscesses develop in response to a parenchymal infection with pyogenic bacteria, beginning as a localized area of cerebritis and evolving into a suppurative lesion surrounded by a well-vascularized fibrotic capsule.

Can tuberculosis cause brain abscess?

tuberculosis is a rare cause of brain abscess; however, this organism should be considered in patients with disseminated tuberculosis or in individuals from areas where tuberculosis is endemic. [2] The present study noticed four (5.4%) TBA cases in five-year study on brain abscesses.

How does tuberculosis affect the brain?

Untreated, this disorder can lead to seizures, hydrocephalus (accumulation of fluid in the brain cavity), deafness, mental retardation, paralysis of one side of the body (hemiparesis) and other neurological abnormalities.

What is the pathophysiology of tuberculosis?

Arthur Dannenberg described the pathology of tuberculosis in detail [2, 3]. There are five stages: onset, symbiosis, early stages of caseous necrosis, interplay of cell-mediated immunity and tissue damaging delayed-type hypersensitivity, and liquefaction and cavity formation.

What causes abscess?

Most abscesses are caused by a bacterial infection. When bacteria enter your body, your immune system sends infection-fighting white blood cells to the affected area. As the white blood cells attack the bacteria, some nearby tissue dies, creating a hole which then fills with pus to form an abscess.

Which nerve is affected in TB meningitis?

Because TB meningitis is a chronic disease, cranial nerve palsies are common manifestations. This report suggests that TB meningitis should be a disease of differential diagnosis for isolated oculomotor nerve palsy.

Can tuberculosis cause brain tumors?

Cerebral tuberculoma is a rare cause of intracranial mass. In Latin America and Colombia where tuberculosis is endemic, it represents between 5 and 30% of brain tumours.

What is the cause of tuberculous meningitis?

TB meningitis (Tuberculous meningitis) is caused by the Mycobacterium tuberculosis bacteria. Infection begins elsewhere in the body, usually the lungs, but in about 1 – 2% of cases the bacterium causes TB meningitis.
