摘要：RETROPERTIONEAL HEMATOMAS ARE USUALLY A COMPLICATION OF A BLUNT ABDOMINAL TRAUMA, AORTIC ANEURYSMS, NEOPLASMS SITUATED IN THE RETROPERTIONEAL SPACE OR VASCULAR INJURIES. IDIOPATHIC HEMATOMAS ARE A VERY RARE FINDING IN PATIENTS WITH ACUTE SURGICAL ABDOMEN AND BECAUSE OF THE RARITY OF THIS PATHOLOGY, DIAGNOSIS AND TREATMENT IS OFTEN DELAYED AND MAY POTENTIALLY BE FATAL. MRI OR AN ENHANCED COMPUTER TOMOGRAPHY ARE THE ELECTIVE METHODS FOR DIAGNOSING RETROPERITONEAL HEMATOMAS, BUT IN SOME CASES RESULTS MAY BE INCONCLUSIVE, THE NEXT STEP BEING A DIAGNOSTIC LAPAROSCOPY. WE PRESENT THE CASE OF A 47 YEAR OLD MALE PATIENT WHO PRESENTED IN THE EMERGENCY ROOM WITH NO HISTORY OF RECENT TRAUMA OR ANTICOAGULATION TREATMENT FOR KNOWN PATHOLOGIES ACCUSING PAIN IN THE RIGHT ILIAC FOSSA AND RIGHT UPPER QUADRANT, LUMBAR PAIN AND SIGNIFICANT WEIGHT LOSS. AFTER A CT SCAN WAS PERFORMED THAT SHOWED A RETROPERTIONEAL MASS HE WAS ADMITTED IN OUR SURGICAL WARD FOR FURTHER INVESTIGATION AND TREATMENT.
