We report six unusual cases of hydatid cyst and discuss manage¬ment problems in hydatid disease. Our first patient had a neuro¬logical deficit due to a paravertebrally located cyst. In the second case, a cyst was found in the soft tissue of the chest wall. In anot¬her patient the cyst was bulging through the old thoracotomy scar. Iatrogenic cyst rupture was present in the fourth case. The fifth case had biloptysis due to a liver cyst. In the last case a cyst was found in the thorax accidentally.
