Transient bilateral Basal Ganglia lesions in rotavirus encephalopathy. A case report.

Rotavirus gastroenteritis may be associated with the onset of an acute reversible encephalitis. We describe a case of transient bilateral basal ganglia lesions after a prodromal gastroenteritis which completely resolved four months later. Diffusion weighted images were determinant to depict the basal ganglia abnormalities and were helpful to evaluate the prognosis. A review of the literature indicates that many diseases may be accompanied by signal abnormalities within the basal ganglia and that differential diagnosis is possible only through the simultaneous evaluation of imaging, clinical and laboratory findings.
