The nutcracker syndrome is caused by the obstruction of the left renal vein secondary to its compression between the superior mesenteric artery and the aorta. Clinically, this syndrome manifests with pain, hematuria, varicocele or lower urinary tract symptoms. The prevalence of this syndrome is currently unknown; however, the diagnosis of this condition has increased thanks to the availability of non-invasive studies that allow its recognition. On the other hand, IgA nephropathy is the most common type of glomerular disease worldwide. Almost 15% of the causes of hematuria in children are secondary to this condition. The combination of IgA nephropathy and the nutcracker syndrome is rare. In the current literature, few cases have been described. We described the case of a 9-year-old scholar with hematuria and persistent proteinuria in the course of a purpura of Henoch-Schonlein in whom renal biopsy documented IgA nephropathy. However, during follow-up, due to the persistence of hematuria and proteinuria, in addition to other symptoms, additional studies are carried out confirming a Nutcracker syndrome. It is key in patients with persistent symptoms to rule out the association of these two diseases to avoid unnecessary interventions.
