Hématome spontané du rein

We here report the case of a 54-year old patient with a history of appendectomy performed 6 years before and suffering from left lower back pain evolving for 3 months aggravated 3 days before admission to the Emergency Department. Moreover, there was no sign of hematuria or stones emission nor of lumbar or abdominal trauma. On admission physical examination showed fairly good general condition, slight discoloration of the conjunctivas, hemodynamic stability. Laboratory tests showed hemoglobin at 7.7g/dl, the remainder of the laboratory tests was normal. Uroscan revealed a predominantly posterior heterogeneous,voluminous left peri-renal collection with spontaneous hyperdense areas (A). The patient underwent two packed red blood cell transfusion. Simple monitoring associated with analgesic and antibiotic treatment to avoid superinfection of the hematoma was performed based on hemodynamic stability. Control uroscan was performed one month later showing marked regression of the hematoma (B).
