[A child with inexplicable alteration of consciousness]

Area of Science:

• Neurology
• Pediatrics
• Infectious Diseases

Background:

• Rotavirus is a common cause of gastroenteritis in children.
• Encephalopathy is a rare but serious complication of viral infections.
• Splenial lesions of the corpus callosum can occur in various encephalopathic conditions.

Observation:

• A 4-year-old girl experienced altered consciousness and speech arrest following vomiting, diarrhea, and fever.
• Brain MRI revealed a focal lesion in the splenium of the corpus callosum.
• Rotavirus was identified in fecal samples.

Findings:

• The clinical presentation and MRI findings were consistent with mild encephalopathy.
• A reversible splenial lesion was observed.
• The neurological symptoms resolved, indicating the lesion's transient nature.

Implications:

• This case suggests a direct link between rotavirus infection and mild encephalopathy with splenial lesions.
• Early recognition and diagnosis are crucial for managing such cases.
• Further research may elucidate the precise mechanisms of rotavirus-induced encephalopathy.
