Congenital primary cerebral angiosarcoma: CT, US, and MR findings

Congenital primary intracranial angiosarcoma (CAS) is an exceptionally rare tumor. To our knowledge the imaging features of intracranial angiosarcomas have only been briefly mentioned in the neuropathologic literature. To our knowledge, only one case of CAS has been reported. We present a case of a pathologically proven CAS found in a neonate.
