A pattern of symmetrical cerebellar involvement and presence of microbleeds/haemorrhage may serve as a useful imaging marker and may help in the diagnosis of dengue encephalitis.

DTI is a useful tool for identifying gross histological features of pachygyria-agyria complex. Superficial layer and thickened fourth layer demonstrate high anisotropy. Identification of anisotropy in the superficial layer has not been described in previous reports.

Maple syrup urine disease (MSUD) is a rare metabolic disease affecting the neural tissue. While the brain abnormalities present on MRI are well known, spinal imaging features have not been studied. We herewith report an unusual finding of enlarged Virchow Robin spaces in brain and novel spinal cord changes in two biochemically diagnosed cases of MSUD. To the best of our knowledge, spinal MRI findings in cases of MSUD have not been previously reported. Knowledge of spinal MRI findings may be useful in diagnosis of this rare disorder.

We report a case of double aortic arch in a 12-month-old male infant well delineated on 64 slice computed tomography scan. It formed a complete vascular ring around the trachea compressing it. The symptoms resolved after surgical division of the ring.
