Most common manifestations are seizures and acute focal neurological\u00a0deficits. We present a case report of a seventy-one year-old man with a two-month history of behavior changes, attention deficit\u00a0and indifference followed by gait unsteadiness. Neuropsychological evaluation showed severe cognitive impairment and executive\u00a0dysfunction. Head computed tomography depicted a supraventricular hydrocephaly. Magnetic resonance imaging revealed a small\u00a0hemorrhage, contiguous to a mesencephalic cavernous angioma, obstructing the Sylvius aqueduct, causing secondary hydrocephalus.\u00a0Four months after endoscopic ventriculocisternostomy, neuropsychological evaluation showed improvement and the patient regained\u00a0autonomy. Parenchyma cavernous angiomas causing direct hemorrhage and subsequent obstruction of the Sylvian aqueduct are\u00a0uncommon. Sub-acute behavior and mental state abnormalities are rare first manifestations of cavernous angioma and requires high\u00a0clinical suspicion for its correct diagnosis. Magnetic resonance imaging evaluation is crucial in the detection of such patients as prompt\u00a0neurosurgical intervention may substantially improve cognitive function.<\/jats:p>","DOI":"10.20344\/amp.7523","type":"journal-article","created":{"date-parts":[[2017,2,27]],"date-time":"2017-02-27T16:37:27Z","timestamp":1488213447000},"page":"77-79","source":"Crossref","is-referenced-by-count":1,"title":["Behavior Changes and Gait Unsteadiness: The Value of Imaging and Prompt Neurosurgical Intervention"],"prefix":"10.20344","volume":"30","author":[{"given":"Andreia","family":"Costa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cl\u00e1udia","family":"Marques-Matos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carina","family":"Reis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta","family":"Carvalho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Madalena","family":"Pinto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8464","published-online":{"date-parts":[[2017,1,31]]},"container-title":["Acta M\u00e9dica Portuguesa"],"original-title":[],"link":[{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/download\/7523\/4897","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/download\/7523\/4897","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,10,25]],"date-time":"2022-10-25T21:05:31Z","timestamp":1666731931000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/view\/7523"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,1,31]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2017,1,31]]}},"URL":"https:\/\/doi.org\/10.20344\/amp.7523","relation":{},"ISSN":["1646-0758","0870-399X"],"issn-type":[{"value":"1646-0758","type":"electronic"},{"value":"0870-399X","type":"print"}],"subject":[],"published":{"date-parts":[[2017,1,31]]}}}
