[Pregnancy and hydatid cyst].

Cyst hydatid disease (CHD) can be localized in every organ and frequently seen in Turkey. Twenty weeks pregnant woman was admitted with hemoptysis and dyspnea. Chest X-ray revealed bilateral homogeneous dansities. We planned to end pregnancy or follow until term, as diagnosis of CHD. The patient refused delivery. Eleven months later she was admitted with haemoptysis and syncope. Chest X-ray showed cavitary lesion, pleural effusion, pneumothorax in right lung and another cavitary lesion in left. Tube thoracostomy performed with the diagnosis of perforated cyst hydatid (CH) and the patient operated. CH may enlarge in pregnancy. Cyst rupture can cause anaphylactic shock and hemoptysis. Pregnancy and CHD occur occasionally together and there is no consensus about treatment.
