A – macroscopic appearance of cysts in the brain and cerebellum. Coenurus cysts in the right frontal lobe (black arrow) and in the left cerebellum (white arrow). B – microscopical appearance of the inflamed area around the cyst in the brain. Calcification (thin arrow), mononuclear cell infiltration (white arrow), hyperaemia (arrowhead), H&E, 100×. C – giant cell (thin arrow), mononuclear cell infiltration (asterisk), necrosis (white arrow), hyperaemia (arrowhead), H&E, 100×
