Embolization for Hemorrhagic Multiple Intrarenal Microaneurysms Following Percutaneous Renal Biopsy in A Patient With Systemic Lupus Erythematosus

Although patients with systemic lupus erythematosus (SLE) have a high incidence of arterial and venous thrombotic manifestations, intrarenal microaneurysms have been quite rarely reported in these patients, and are probably unrecognized. We report a case of SLE which was complicated with huge retroperitoneal hemorrhage due to rupture of pseudoaneurysm following renal biopsy, associated with multiple microaneurysms. On angiography, multiple microaneu-rysms of the intralobular arteries and bleeding from the lower pole renal pseudoaneurysm were seen, which was embolized with gel foam. This case represents an unusual presentation of SLE.
