3D Printed Berry Aneurism of Basilar Artery

3D Printed Berry Aneurism of Basilar Artery Clinical HistoryA 37-year-old patient presented to hospital after falling and striking his head, with subsequent symptoms of headache, vomiting and disorientation. CT scan showed dilatation of the lateral ventricles associated with a large mass projecting into the third ventricle posteriorly. One week later a shunt was performed for hydrocephalus. An angiogram revealed a partially thrombosed aneurysm, measuring 1 x 1 cm, arising from the basilar artery. At 3-months post-op the shunt was revised due to obstruction, with repeat cerebral angiogram revealing interval enlargement of the aneurysm. Attempted ligation of the aneurysm was unsuccessful. The patient remained unconscious despite several attempts to revise the shunt and he died. PathologyThis brain has been sliced in the mid-sagittal plane. It comprises a whole hemi-section of the brain about 1cm thick. On the medial surface a large darkly-coloured ovoid berr
