THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Infectious diseases of the brain and spinal cord, including meningitis and encephalitis. CSF tests for infections look at white blood cells, bacteria, and other substances in the cerebrospinal fluid.

Detailed explanation-2: -CSF pleocytosis is important in establishing the diagnosis of central nervous system (CNS) infections such as meningitis, encephalitis, and meningoencephalitis. However, the absence of pleocytosis represents a diagnostic challenge to clinicians when suspecting a CNS infection.

Detailed explanation-3: -A definitive diagnosis of meningitis requires a spinal tap to collect cerebrospinal fluid. In people with meningitis, the fluid often shows a low sugar level along with an increased white blood cell count and increased protein. Analyzing the fluid also may help identify which bacterium caused the meningitis.

Detailed explanation-4: -Blood tests. A blood test examines a sample of blood for evidence of infection. Computed tomograpgy (CT) or magnetic resonance imaging (MRI). These special imaging tests produce cross-sectional images of the body. Spinal tap.
