The toxic reactions are insignificant exceptafter rupture of the cyst, when they may include {a) such symptomsas syncope or urticaria ; (6) local inflammatory processes from directcontact with hydatid-fluid (peritonitis) ; (c) chronic toxic effects, wasting and ansemia. Hydatid cysts are therefore not inertforeign bodies, but must be regarded as living structures which are 328 GYNECOLOGY. Fig. 156.
