On examination of the patient, the swelling of 12 cm x 4 cm was observed on the right lateral neck (Figures 1(a) and 1(b)).

On the CT brain, there was no evidence of shunt intracranially, its proximal end lying just external to the cranium was present (Figure 3), and hydrocephalus was present (Figure 4).
