We present a case of a spontaneous retroperitoneal hematoma in a 62 year-old man who was using acethylsalicylic acid (ASA). Spontaneous retroperitoneal hematoma is a rare, but potentially serious complication of anticoagulation therapy. Through literature revision, we have discussed the etiological aspects of this disease and the importance of obtaining the preoperative diagnosis for an appropriate and conservative operative treatment.
