Pathological examinations of the resected tissue. a Hematoxylin and eosin staining reveals thickening of the vessels in the mesentery. Scale bar, 200 μm. b Elastica-Masson staining reveals collagenous fibrosis (green) of the vessel walls. Inflammatory cells such as lymphocytes, polymorphonuclear cells, and multinucleated giant cells are infiltrating around the vessels, suggesting focal inflammation associated with the coil embolization
