Germanic, one of the language groups descended from this ancestral speech, is usually divided by scholars into three regional groups: East (Burgundian, Vandal, and Gothic, all extinct), North (Icelandic, Faroese, Norwegian, Swedish, and Danish), and West (German, Dutch [and Flemish], Frisian, and English).
Cavernous hemangioma, also called cavernous angioma, or cavernoma (often when referring to presence in the brain), is a type of blood vessel malformation or hemangioma, where a collection of dilated blood vessels form a tumor. Because of this malformation, blood flow through the cavities, or caverns, is slow.
A cavernous sinus thrombosis is a blood clot within the cavernous sinus. This clot causes the cavernous sinus syndrome. The cavernous sinus syndrome is characterized by edema (swelling) of the eyelids and the conjunctivae of the eyes and paralysis of the cranial nerves which course through the cavernous sinus. The orbital cavity is drained by paired veins called the superior and inferior ophthalmic veins. The superior ophthalmic vein arises at the inner angle of orbit and follows the course of ophthalmic artery into the cavernous sinus, a greatly dilated (widened) channel of venous blood.
