Hydatid disease is endemic in many regions of Turkey. We observed 23 c
ases of simultaneous liver hydatid cyst in 344 patients having pulmona
ry hydatid cyst referred to our center. The simultaneous hydatid cysts
were diagnosed by ultrasonography. In all cases complete resection wa
s possible in a single operation. We performed thoracophrenotomy in 21
cases and thoracolaparotomy in two cases. Empyema was observed in thr
ee patients postoperatively. No mortality has occurred. Recurrence of
a pulmonary cyst was observed in one patient 20 months postoperatively
.
