Have birthmark on head mri last week shown diffuse haemangioma in skull bone ?! should i be worried cant stop panicking risk of death?

These: lesions are almost always BENIGN!! They are NOT associated with a risk of death. Follow your Primary Health Care Provider's lead and consult with the proper surgeon if removal is being considered. Hope this helps! Dr Z

Hemangioma: This type problem is typically not life threatening. Talk to your provider lazer surgery is effective for hemangiomas.

Relax: These grow their fastest before you reach a year of age and then settle down and just sit or shrink. If you made it to your age you are fine. It is more of a curiosity than a risk. Follow your docs lead on this and settle back into your life.I would't be surprised if they sent you around to a few docs to share the curious finding.
