Two cases of broncholith
removal under the guidance of flexible bronchoscopy.
DISCUSSION: Lithoptysis is a condition in which erosion and extrusion of calcified peribronchial lymph nodes into the lumen (Broncholith
), which is associated with necrotizing granulomatous lymphadenitis.
A calcified or ossified endobronchial lesion without an associated soft-tissue component constitutes a broncholith
, having likely reached its location by erosion of a calcified lymph node through an airway wall.
are more common on the right side because of airway anatomy and lymph node distribution.
