CT
Axial non-contrast
Left scalp laceration noted.
No intracranial haemorrhage identified. Grey white matter differentiation is preserved. An irregular, heterogenous, 27 mm, intraventricular mass is seen within the right lateral ventricle, possibly arising from the septum pellucidum. It does not show calcification. Mild prominent of the right lateral ventricle is probably due to normal asymmetry. Foramen magnum appears full however I note that the fourth ventricle is not dilated
