title: Can a warning leak in a patient with unruptured aneurysm mask an underlying gastrointestinal pathology? A case report.
abstract: Aggravating headache accompanied by nausea and epigastric discomfort suggesting a warning leak in a 39-year-old woman with a giant thrombosed intracranial aneurysm prompted us to undertake coiling of the aneurysm. After uneventful coil embolization of the aneurysm, collapse of the lung related to bronchospam developed, and was found to have a gastrointestinal pathology which had gone undetected before the procedure. Despite its rarity, gastrointestinal pathology mimicking warning leak should have been considered in a patient with a warning leak sign.
