Fig. 8From: Novel method using DW-MRI and ADC images to guide stereotactic biopsy for the diagnosis small primary angiitis of the central nervous system: a case reportThe postoperative pathological diagnosis was vasculitis. Hematoxylin–Eosin staining (HE) shows the histology of isolated vasculitis; immunohistochemistry (IHC) shows the expression of leucocyte common antigen (LCA) and smooth muscle actin (SMA) in isolated vasculitis. A HE (40×). B HE (100×). C IHC of LCA expression (100×). D IHC of SMA expression (100×)Back to article page
