==== Primary brain angiosarcoma ====
Primary brain angiosarcoma are angiosarcoma that arise in the brain (i.e. not metastasised from elsewhere). They are exceedingly rare with only a few cases reported. Imaging is non specific and differential diagnosis includes most other brain tumors such as [[glioma]]s or [[Cavernous hemangioma|cavernomas]],<ref name="Angiosarcoma" /> requiring biopsy to confirm diagnosis, usually after surgery. Prognosis is generally poor with a median survival rate of eight months. However it varies greatly depending on whether or not the tumor has metastasised, some individuals may be rid of the disease following surgery, chemotherapy and radiation therapy.<ref>{{Cite journal|last1=La Corte|first1=Emanuele|last2=Acerbi|first2=Francesco|last3=Schiariti|first3=Marco|last4=Broggi|first4=Morgan|last5=Maderna|first5=Emanuela|last6=Pollo|first6=Bianca|last7=Nunziata|first7=Raffaele|last8=Maccagnano|first8=Elio|last9=Ferroli|first9=Paolo|date=April 2015|title=Primary central nervous system angiosarcoma: a case report and literature review|url=https://pubmed.ncbi.nlm.nih.gov/25388456/|journal=Neuropathology |volume=35|issue=2|pages=184–191|doi=10.1111/neup.12178|issn=1440-1789|pmid=25388456|s2cid=21199506}}</ref>
