Spontaneous bilateral perirenal hematomas in two patients with eclampsia.

The purpose of this report is to provide two illustrative cases of spontaneous and bilateral perirenal hematomas that occurred during a pregnancy complicated by eclampsia. The sonographic and computed tomographic findings included bilateral perirenal hematoma with no evidence of an underlying malignancy. Since renal hematomas that occur in association with preeclampsia and eclampsia syndrome are extremely rare, but potentially life-threatening complications, prompt laboratory and radiologic evaluations are essential and can reduce the associated morbidity and mortality.
