Cavernous hemangioma can involve intravascular thrombosis and which type of calcification?

• A. Metastatic
• B. Fibrous
• C. Dystrophic
• D. Ossified

Answer: (C)

In cavernous hemangiomas, blood can pool and form intravascular thrombi. Over time, these thrombi can organize and calcify even when calcium metabolism in the body is normal. This local, tissue-degraded calcification is called dystrophic calcification, and in vascular malformations it often presents as phleboliths—calcified thrombi within veins that are characteristic of these lesions. So the calcification most associated with this setting is dystrophic calcification. Metastatic calcification would occur with high calcium levels affecting normal tissues, ossification would imply true bone formation, and fibrous calcification isn’t the typical descriptor for this scenario.
