A Case of Intraparenchymal Pseudoaneurysms in Kidney Allograft

Patient: Male, 31 Final Diagnosis: Intraparenchymal pseudo-aneurysms in kidney transplant Symptoms: Asymptomatic Medication: — Clinical Procedure: Percutaneous renal biopsy Specialty: Transplantology OBJECTIVE: Diagnostic/therapeutic accidents BACKGROUND: Percutaneous needle biopsy is routinely performed for renal allograft management. Vascular complications of the procedure include pseudoaneurysm and arterio-venous fistulae formation. Delayed diagnosis of these complications is due to their mostly asymptomatic and indolent nature. CASE REPORT: We present a case of extensive intraparenchymal pseudoaneurysm formation within the inferior pole of the allograft, diagnosed two years following the most recent biopsy procedure. CONCLUSIONS: Renal pseudoaneurysms may only be diagnosed years after their formation as they are typically asymptomatic.
