Answer :
Final answer:
Correct answer is a) .The diagnosis for painful pharyngeal muscle spasms with eosinophilic cytoplasmic inclusions in hippocampal neurons (Negri bodies) is Rabies. Negri bodies are specific to rabies, differentiating it from conditions like tetanus and meningitis.
Explanation:
The diagnosis for painful pharyngeal muscle spasms with eosinophilic cytoplasmic inclusions in hippocampal neurons (Negri bodies) is Rabies. Rabies is a deadly virus that affects the central nervous system, leading to severe neurological symptoms. Negri bodies are a hallmark of rabies infection, found in the neurons of infected individuals.
Generalized tetanus, another potential diagnosis, typically presents with symptoms like lockjaw and muscle spasms due to the toxin TeNT, but it does not involve Negri bodies. Meningitis, often considered when central nervous system infection is suspected, involves inflammation of the protective membranes covering the brain and spinal cord and does not feature Negri bodies, which are specific to rabies.
