Radiological features of the neuroectodermal tumours of childhood.

The radiological features of 10 cases of primitive neuroectodermal tumour (primary cerebral neuroblastoma) are presented. The angiographic and CT appearances were similar to those previously described in the literature. However, not previously documented was evidence on plain skull radiographs and CT scans of thinning and expansion of the overlying vault in 6 of the 10 cases.
