Dr. Nimesh Agrawal, Dr. Sarfaraz Shaikh, Dr. Madan Manmohan

Abstract: Pyogenic meningitis, also referred as bacterial meningitis, is a life-threatening CNS infectious disease affecting the meninges, with elevated mortality and disability rates. Three bacteria (Haemophilus influenzae, Streptococcus pneumoniae, Neisseria meningitidis) account for the majority of cases. Meningeal lesions pose diagnostic challenges, and knowledge of the clinical and imaging features of various conditions, including infection, autoimmune diseases, primary and secondary tumors, tumorlike diseases, and medication-induced diseases, is necessary for correct diagnosis.
