"The condition is characterised by thickening of the fatty subcutaneous layer of the scalp, over 9 mm but up to several centimetres; the normal thickness of the scalp in adults is ~6 mm measured at the bregma 2. This is visible on CT, ultrasound and MRI, but care should be taken not to mistake rolled up folds of loose scalp or an oblique section through the scalp as actual thickening."
