| Abstract: | We describe a 4-month-old girl presenting with a melanotic neuroectodermal tumour of infancy at the anterior fontanelle.
According to the neuroimaging findings, this tumour was found to lie epidurally, adherent to the dura mater, with thickening
of the adjacent frontal bone. The tumour was dense on CT, while MRI showed a major part of the tumour to be isointense with
cerebral cortex on both T1- and T2-weighted images. The neuroimaging and clinical features are briefly discussed.
