Polyneuropathy and cerebral infarction complicating scrub typhus

Area of Science:

• Neurology
• Infectious Diseases
• Medical Case Reports

Background:

• Scrub typhus is an infectious disease caused by Orientia tsutsugamushi.
• Neurological complications of scrub typhus are uncommon.
• Cerebral infarction and polyneuropathy are rarely reported manifestations.

Purpose of the Study:

• To describe a unique case of scrub typhus with concurrent polyneuropathy and cerebral infarction.
• To document the clinical and electrophysiological findings in this complex presentation.
• To contribute to the understanding of rare neurological sequelae of scrub typhus.

Main Methods:

• Case presentation of a 64-year-old male patient.
• Detailed neurological examination.
• Electrophysiologic studies (nerve conduction studies, EMG).
• Brain magnetic resonance imaging (MRI).

Main Results:

• The patient presented with confusion, stiff neck, hearing impairment, symmetric weakness, sensory loss, and ataxia.
• Electrophysiology revealed demyelinating sensorimotor polyneuropathy and sensorineural hearing loss.
• Brain MRI demonstrated multiple cerebral infarctions.

Conclusions:

• This case highlights the potential for severe and diverse neurological involvement in scrub typhus.
• The co-occurrence of polyneuropathy and cerebral infarction is exceptionally rare.
• Further research is needed to elucidate the pathogenic mechanisms behind these complex neurological complications.
