Ruptured intrathoracic cyst during induction of anaesthesia: Anaesthetic challenges.

Congenital benign cysts are among the rare types of mediastinal masses. When symptomatic, complete surgical excision through thoracotomy is the definitive treatment. Rarely they may present with symptoms due to complications like rupture. However, rupture following the induction of general anaesthesia poses unique challenges for anaesthesiologist. We report our experience of a rare variant of intraparenchymal cyst (lung), which was subsequently found to be a bronchogenic cyst.
