Isolated Oculomotor Neuritis After Dengue Fever

Area of Science:

• Neurology
• Infectious Diseases
• Ophthalmology

Background:

• Dengue fever can present with diverse neurological complications.
• Oculomotor nerve palsy is an uncommon sequela of dengue infection.

Observation:

• A rare case of isolated partial left third cranial nerve palsy was observed.
• The palsy was attributed to inflammatory oculomotor neuritis.
• The condition occurred subsequent to a dengue fever infection.

Findings:

• Unique neuro-imaging findings were documented.
• Enhancement was observed along the entire course of the left oculomotor nerve on imaging.
• This pattern suggests extensive inflammatory involvement of the nerve.

Implications:

• This case expands the spectrum of neurological manifestations of dengue fever.
• It highlights the importance of considering oculomotor neuritis in patients with cranial nerve palsies post-dengue.
• The imaging findings provide insights into the pathophysiology of dengue-associated oculomotor nerve dysfunction.
