Question
After undergoing a brain CT scan, the doctor diagnosed the presence of hemorrhage. What characteristic manifestations will appear after bleeding from a hemangioma?
Answer
Hemangiomas have a structure similar to foam, resembling grape clusters in shape, composed of tiny tumors. When these tumors hemorrhage, they appear as annular low-density areas on imaging, due to the deposition of hemosiderin. For brain hemangiomas, gamma knife treatment is an effective and minimally invasive option, without the need for general anesthesia or invasive surgery. However, the best treatment plan should be tailored to individual conditions.
