A Rare Case of Japanese Encephalitis Presenting like Tetanus

Results a n d discussionIn this patient, MRI findings were suggestive of encephalitis, and CSF viral panel was positive for JE.Movement disorders are intRoduction Japanese encephalitis (JE) is an important cause of viral encephalitis in endemic regions and commonly presents with fever, altered sensorium, seizures, and focal neurological deficits.Movement disorders, including dystonia and abnormal posturing, are recognized but less common manifestations, often associated with basal ganglia involvement.Acute dystonic presentations may clinically resemble tetanus, creating diagnostic challenges.We report a rare case of Japanese encephalitis presenting with trismus, drooling, and muscle spasms mimicking generalized tetanus, highlighting the importance of considering central nervous system infections in patients with acute-onset movement disorders.
