Tow views of the skull


There are multiple round lucencies scattered through the calvarial bones, being more pronounced posteriorly.

Case Discussion

This case illustrates the typical appearance of convolutional markings of the skull. These images were taken as a part of skeletal survey for suspicious non-accidental trauma. It is important to differentiate this appearance from copper-beaten skull and lacunar skull. However, in our case, both the imaging findings and the clinical history, mostly compatible with normal convolutional markings.
