Key result
Rotavirus gastroenteritis linked to transient basal ganglia lesions that resolve completely after four months.
Why the study?
Rotavirus gastroenteritis may be associated with acute reversible encephalitis with transient bilateral basal ganglia lesions, requiring imaging for diagnosis and prognosis evaluation.
Case Report (n=1)
Diffusion weighted imaging is useful for depicting basal ganglia abnormalities and evaluating prognosis in rotavirus encephalopathy.
Should not yet change practice; hypothesis-generating for DWI in rotavirus encephalopathy prognosis.
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.

Messina et al. (2010) conducted a case report in Rotavirus encephalopathy (n=1). Rotavirus gastroenteritis was evaluated on Transient bilateral basal ganglia lesions. Rotavirus gastroenteritis was associated with transient bilateral basal ganglia lesions that completely resolved after four months, with diffusion-weighted imaging aiding in prognosis.
