title: Case report: parenchymal pseudoaneurysm of a renal allograft after core needle biopsy: a rare cause of allograft injury.
abstract: There are multiple causes of worsening graft function after initial good function in cadaveric kidney transplant. In this report, we discuss a rare one: a traumatic pseudoaneurysm caused by a 14-gauge core needle biopsy in a 55-year-old woman. She had immediate graft function followed by rapid decline in the first postoperative week. Imaging studies showed an intraparenchymal 2-cm pulsatile mass with turbulent blood flow in the upper pole at the corticomedullary junction. Angiography the following morning confirmed the diagnosis of pseudoaneurysm. It was coiled successfully, with restoration of graft function. Although development of a pseudoaneurysm is a rare event, transplant centers must be cognizant of allograft injuries like this one.
