Cerebral cavernous malformation (CCM) is a cavernous hemangioma that arises in the central nervous system.It can be considered to be a variant of hemangioma, and is characterized by grossly large dilated blood vessels and large vascular channels, less well circumscribed, and more involved with deep structures, with a single layer of endothelium and an absence of neuronal tissue within the lesions.

An angioma refers to any type of benign vascular tumor. [2] Some vascular tumors can be associated with serious blood-clotting disorders, making correct diagnosis critical. [3] A vascular tumor may be described in terms of being highly vascularized, or poorly vascularized, referring to the degree of blood supply to the tumor.
After filtering out respondents with symptoms like headache and fatigue prior to infection as a result of unrelated conditions like seasonal allergies, the team found that nearly one in four COVID ...
