Rat brain tissue that developed cisticerci. A: Masson's trichromic stain to identify the collagen layer surrounded the cyst; the arrow indicates the collagen layer stain blue. B–D: Brain tissue hematoxylin and eosin stain. B: Spongy change; the arrows indicate the rarefaction and vacuolation of the neurophil in the brain tissue surrounding the cyst. C: The arrow indicates the thickened walls of small blood vessel, and the arrowhead indicates the perivascular infiltrate. D: The arrows indicate angiogenesis with small blood vessels spreading into fibrotic tissue. Scale bar = 50 μm. Original magnification: ×4 (B); ×40 (C and D). L, lumen; P, parasite.
