Abstract
We present a case involving a 70-year-old Latina woman who experienced a sud-den onset of lightheadedness, diplopia, vertigo, and loss of balance. Imaging studies revealed a right thalamic intracerebral haemorrhage that obstructed the velum interpositum. Following unsuccessful embolisation, the thalamic region was surgically resected. Histopathological and immunohistochemical analyses of the resected brain tissue demonstrated abnormal blood vessels permeating through excessively cellular brain parenchyma, raising significant concern for a glial neoplasm. This case also illustrates a rare occurrence of an arteriovenous malformation within the velum interpositum, which, when acutely filled with blood, can expand the cavum and clinically present as a sudden onset of headache and vertigo.
期刊介绍：
Polish Journal of Pathology is an official magazine of the Polish Association of Pathologists and the Polish Branch of the International Academy of Pathology. For the last 18 years of its presence on the market it has published more than 360 original papers and scientific reports, often quoted in reviewed foreign magazines. A new extended Scientific Board of the quarterly magazine comprises people with recognised achievements in pathomorphology and biology, including molecular biology and cytogenetics, as well as clinical oncology. Polish scientists who are working abroad and are international authorities have also been invited. Apart from presenting scientific reports, the magazine will also play a didactic and training role.
