3D Printed Cerebral Arterio-Venous Malformation

3D Printed Cerebral Arterio-Venous Malformation Clinical HistoryThis patient died at the age of 58 years from post-operative complications following transurethral resection of the prostate. At the ages of 28 and 35, he had suffered two episodes of transient neurological deficit. However, at 50 years, he developed permanent hemiparesis of the left leg chiefly affecting his ankle. Pathology The specimen is a coronal slice of the brain that passes through the parietal lobes. Cortex and white matter on the medial aspect of the right cerebral hemisphere have been replaced by a mass of abnormal tissue 4 cm in greatest diameter. This lesion extends from the superior surface down to the roof of the lateral ventricle. A closer inspection reveals the tissue to be a network of tortuous vascular channels and intervening tissue.Histological examination of this arterio-venous malformation showed glial tissue surrounding dilated vessels. All vessels had a typical endot
