Aseptic meningitis is a common condition, which is caused by many viruses but also from autoimmune etiologies. MRS occurs in 8% of aseptic meningitis cases. Average latencies from the onset of meningeal irritation to urinary symptoms were 0–8 days. However, in some cases, urinary retention precedes fever and headache.
Brudziński's sign or a Brudziński sign is any of three medical signs, all of which may occur in meningitis or meningism.All three are named after Józef Brudziński. [1] In English, the name is often written without the diacritic (like many borrowed words) (Brudzinski) and is pronounced / b r uː ˈ dʒ ɪ n s k i /.
The classic triad of diagnostic signs consists of neck stiffness, sudden high fever, and altered mental status; however, all three features are present in only 44–46% of bacterial meningitis cases. [ 16 ] [ 17 ] If none of the three signs are present, acute meningitis is extremely unlikely. [ 17 ]
Kernig's sign is a test used in physical examination to look for evidence of irritation of the meninges.The test involves flexing the thighs at the hip, and the knees, at 90 degree angles, and assessing whether subsequent extension of the knee is painful (leading to resistance), in which case it is deemed positive.

Chronic meningitis is defined by signs and symptoms being present longer than four weeks and includes pleocytosis, or the presence of inflammatory cells in the cerebrospinal fluid. [2] The initial test is usually a lumbar puncture to collect cerebrospinal fluid for analysis.
Diagnosis is based on a combination of clinical findings, patient examination, and imaging evaluation. [21] The most common affected area is the lumbar region of the back, and includes the classic symptomatic triad of back pain, neurological deficits, and MRI with notable adhesions. [ 22 ]
Meningism is a set of symptoms similar to those of meningitis but not caused by meningitis. [1] [3] [4] Whereas meningitis is inflammation of the meninges (membranes that cover the central nervous system), meningism is caused by nonmeningitic irritation of the meninges, usually associated with acute febrile illness, [1] [2] especially in children and adolescents. [2]
[6] [7] Suspicion of meningitis is a medical emergency and immediate medical assessment is recommended. Current guidance in the United Kingdom is that if a case of meningococcal meningitis or septicaemia (infection of the blood) is suspected, intravenous antibiotics should be given and the ill person admitted to the hospital.
