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 microaneurysms 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.
