Spontaneous esophageal hematoma is rare, occurring in a context of high esophageal pressure with abnormalities of hemostasis in some cases. We report a case involving the whole length of the esophagus with no evidence of any etiologic factor. The value of CT Scan is reviewed comparatively with esophageal barium examination and endoscopy. CT Scan confirms the diagnosis and the absence of true esophageal perforation. The general course monitored by CT scanning is uneventful, even in the case of extensive mucosal lesions. This justifies the nonaggressive attitude advocated by the majority of authors.
