Histological examination showed the cysts contained pink hyaline-like material, foreign body-type giant cells in the cyst's wall, with chronic inflammatory cell fluid. The gas-filled cysts are identified with CT imaging. The gas contained in the cysts has been analysed and consists of nitrogen, oxygen, argon, carbon dioxide, and sulphur dioxide.[1] Treatment may not be required and no complications follow the resolution of the cysts.[2] It may be associated with immunosuppression, trichomonas, or Haemophilus vaginalis infection.[5][10] Vaginitis emphysematous is characterized by gas-filled cysts in the vaginal wall.[5][4]
