A 10-year-old patient with fever and altered sensorium: a–c Axial T2-weighted images show near symmetrical increased signal intensity in the medial thalami (white arrow), middle cerebral peduncles (black arrow) and pons (asterisk). The possibility of viral encephalitis, likely Japanese encephalitis, was considered. d–e Follow-up MRI: Axial T2-weighted images show hypointense foci (possibly remote haemorrhage) in the thalami with volume loss and an area of gliosis in the pons
