A 48-year-old woman with a large red vascular nevus on her face that she didn’t take seriously because it didn’t hurt, was rushed to the hospital 10 days ago with a sudden cerebral hemorrhage. On March 9, Ms. Li, who has been suffering from hypertension for many years, was cleaning her home when she suddenly fell to the ground with a muffled grunt and was rushed by her family to the provincial Xinhua Hospital, where a CT showed that Ms. Li had a brain hemorrhage, a large hematoma, and a brain hernia. The patient’s pupils were dilated and her body was rigid, and the situation was urgent. Dr. Yu Junwu, deputy chief of neurosurgery, quickly performed craniotomy on the patient, which revealed a 4 cm diameter hemangioma in Ms. Li’s brain. The operation lasted from 12:00 p.m. on March 9 to 6:00 a.m. the next morning, and the patient’s brain hematoma and hemangioma were cleared one by one. Three days after the operation, Ms. Li regained consciousness and was able to walk on the ground yesterday. Yu Junwu introduced that people with large vascular nevi have a much higher chance of developing hemangiomas than ordinary people, and such people are more likely to have more hemangiomas in the brain, liver and kidneys, and hemangiomas on important organs can be life-threatening once they rupture.
