A decreased intake of brightly colored vegetables results in increased levels of serum homocysteine, and homocysteinemia is associated with the progression of arteriosclerosis. Moreover, homocysteinemia is a known risk factor for cerebral infarction. Here, we report three cases wherein multiple simultaneous intracranial hemorrhages developed in the presence of homocysteinemia. The dietary habits of the patients involved indicated that decreased intake of brightly colored vegetables and the consequent progression of arteriosclerosis caused intracranial hemorrhage. Thus, in daily medical care, the measurement of serum homocysteine levels is useful for managing dietary habits and progression of arteriosclerosis.
