Their charts and imaging films were retrospectively reviewed.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>Results\u2014<\/jats:italic>\n                    <\/jats:bold>\n                    We found a preponderance of CPA in young (mean age: 22) females (67%). Clinical symptoms were seizures, disabling headaches, and stroke-like symptoms; hemorrhagic presentations were exceptional. On cross-sectional imaging, CPA demonstrated as a diffuse network of densely enhancing vascular spaces with intermingled normal brain parenchyma. The discrepancy between the large size of the nidus and the small shunting volume, the absence of flow-related aneurysms, the presence of diffuse angiogenesis (eg, transdural supply, progressive arterial occlusion), and the small calibre of a multitude of feeding arteries and draining veins were the angiographic hallmarks of this disease.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>Conclusion\u2014<\/jats:italic>\n                    <\/jats:bold>\n                    The diffuse angiogenetic activity is presumably related to reduced perinidal perfusion and subsequent chronic cortical ischemia. Natural history demonstrates a low risk of hemorrhage. CPA may be regarded as a separate clinical entity different to \u201cclassical\u201d cerebral AVMs, because normal brain is interspersed with the abnormal vascular channels increasing the risk of neurological deficit in aggressive treatments, which in the light of the natural history does not seem to be indicated.\n                  <\/jats:p>","DOI":"10.1161\/strokeaha.107.493080","type":"journal-article","created":{"date-parts":[[2008,1,31]],"date-time":"2008-01-31T21:49:25Z","timestamp":1201816165000},"page":"878-885","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":133,"title":["Cerebral Proliferative Angiopathy"],"prefix":"10.1161","volume":"39","author":[{"given":"Pierre L.","family":"Lasjaunias","sequence":"first","affiliation":[{"name":"From the Service de Neuroradiologie Diagnostique et The\u0301rapeutique (P.L.L., G.R., H.A., A.O., S.H., W.Z., S.G., D.D., T.K.), Ho\u0302pital de Bicetre, Le Kremlin-Bicetre, Paris, France;
