What condition can result from a ruptured emissary vein?

A ruptured emissary vein can lead to intracranial hemorrhage due to its role in draining blood from the skull to the veins of the neck and other areas. When an emissary vein is ruptured, it can allow blood to leak into the cranial cavity, leading to accumulation of blood and subsequent pressure on the brain tissue. This condition is a particular risk in situations like trauma, where the integrity of these vessels can be compromised.

Cephalhematoma, which typically occurs due to bleeding between the skull and the periosteum from the rupture of blood vessels during delivery, is a localized collection of blood that does not directly involve emissary veins. Hydrocephalus, characterized by an abnormal accumulation of cerebrospinal fluid in the ventricles of the brain, and neonatal jaundice, which involves elevated bilirubin levels in newborns, do not arise from problems related to emissary veins. Therefore, the most accurate consequence of a ruptured emissary vein is indeed intracranial hemorrhage.
