What is the Difference Between Cavernous and Capillary Hemangioma?
🆚 Go to Comparative Table 🆚Cavernous and capillary hemangiomas are two types of vascular tumors that can occur in different locations of the body. They have distinct characteristics and appearances:
Cavernous Hemangioma:
- Composed of clumps of dark intraretinal aneurysms.
- Has a "cluster-of-grapes" aspect.
- Thin-walled capillaries are tightly packed.
- Prone to bleeding.
- Can occur in the brain, brainstem, spine, or other areas of the body.
- May cause seizures, intracranial hemorrhages, or death if located in the brain.
Capillary Hemangioma:
- Composed of tortuous, large-diameter capillaries lined by normal endothelium.
- Separated by polygonal interstitial stromal cells.
- Rapid hyperfluorescence is observed in fluorescein angiography.
In the context of orbital hemangiomas, cavernous hemangiomas have much larger lumens, wider and more heavily collagenized trabeculae, and vascular walls created by multilaminar smooth muscle cells. In contrast, capillary hemangiomas consist of two variably admixed zones: solid cellular zones and zones with open vascular lumens, with each vascular unit composed of endothelial cells and pericytes.
Comparative Table: Cavernous vs Capillary Hemangioma
The main difference between cavernous and capillary hemangioma lies in the size and organization of the blood vessels within the tumors. Here is a table summarizing the differences between the two:
Feature | Cavernous Hemangioma | Capillary Hemangioma |
---|---|---|
Size of blood vessels | Large, thin-walled vessels or sinusoids | Many small capillaries |
Organization | Clusters of blood vessels that are widely packed | Clusters of blood vessels that are tightly packed |
Common location | Oral cavity, facial skeleton, liver | Skin, facial skeleton |
Presentation at birth | Usually occurs in adulthood | Often present at birth |
Symptoms | Seizures, blurred or loss of vision, facial drooping, unsteady muscle movements | Red birthmark on the skin, common in premature infants and girls |
Treatment | Surgical removal, depending on size and location | Observation, as they often regress on their own |
Both cavernous and capillary hemangiomas are non-cancerous tumors that develop within the early stages of life and are treatable.
