A 36-year-old white man presented with sudden-onset headache and rapid deterioration of consciousness. Computer tomography revealed a right capsular intra-parenchimal hemorrhage with an intraventricular component; therefore, emergency surgery was performed. Once the hematoma was evacuated, the cause of the hemorrhage was identified as a tumor mass and it was resected. Histopathological and immunohistochemical examinations of the surgical specimen disclosed a diagnosis of atypical central neurocytoma. By using a protocol recently set up in our laboratory, we succeeded in isolating and propagating, for the first time, human endothelial cells from central neurocytoma (CN-ECs). Different analyses revealed that isolated CN-ECs consist of a pure endothelial cell population, with the expression of endothelial markers (CD31, CD309/VEGFR2, CD105, eNOS) and with angiogenic properties, such as the uptake of LDL. Moreover, CN-ECs spontaneously organize in a vascular-like structure. The goal of this case report is to stress the need for further studies focused on understanding the causes of the onset of an intra-parenchimal hemorrhage in the presence of an atypical central neurocytoma in order to tailor treatments to each single patient and achieve the best clinical outcome.
