Patient's question:
My son suffers from congenital cerebral arteriovenous malformation. There is a subcutaneous mass on his left forearm, approximately 2~3 cm in size, soft in texture, well-defined, with no rupture, normal temperature, and localized tenderness. Every day at home, I see his condition worsening, and it is very painful to watch. I want to know the cause of this disease. How are vascular malformations produced?Doctor's answer:
Angioma is composed of numerous blood sinuses lined with endothelial cells. Among them, the size and shape of the sinuses vary, resembling a sponge-like structure. Blood clots can form within the sinuses and may fibrosify into venous stones. There are several common classifications of angiomas, primarily including microvenous malformations, venous malformations, arteriovenous malformations, lymphatic malformations, and mixed-type angiomas. Some vascular inflammatory conditions are not true tumors and are therefore referred to as angiomas. They are tumors or malformations originating from blood or lymphatic vessels. It is best to undergo an MRI examination, which can provide a basic diagnosis. Due to differences in arterial and venous blood supply, different treatment plans are chosen.
