Background: Crossed renal ectopia is a rare pathology that is often asymptomatic. Intraoperative detection with a sigma complicated neoplasia is more infrequent and requires correct management to avoid a renal ureteral injury.
Aim: To present a case report of a patient with a sigma complicated neoplasia and a crossed renal ectopia detected incidentally.
Case Report: We present the case of a 62-year-old man that was submitted for emergency surgery for a sigma perforated neoplasm, and who presented with a previously undiagnosed left-side CRE. During surgery there was a need to insert 2-double-J stents as a guide to both ureters and to avoid any injury to them.
Discussion: Crossed renal ectopia is a rare, often asymptomatic entity, the diagnosis of which is usually incidental. In our case, the detection of a concomitant complicated neoplasm, required identification of both ureters due the anatomic doubt of its localization and to avoid them being injured. In conclusion, upon finding a casual crossed renal ectopia during an emergency surgery of sigma, we recommend the identification of the ureters to facilitate its location and to avoid any injury to the ureters.

Introduction: The rarest form of renal ectopia, the thoracic kidney, has been documented in only about 200 cases worldwide. There are four recognized causes of congenital thoracic renal ectopia: renal ectopia with an intact diaphragm, diaphragmatic eventration, diaphragmatic hernia, and traumatic diaphragmatic rupture. This condition often presents as an incidental finding in asymptomatic patients.

Background: In recent years, ectopic lymphoid tissue (ELT) has been increasingly confirmed as a new biomarker for kidney injury or inflammation. However, there is insufficient research on the relationship between ELT grading and the progression of idiopathic membranous nephropathy (IMN).
Methods: A total of 147 patients with biopsy-proven IMN in our institution from March 2020 to June 2022 were classified into five grades based on the different distribution of lymphocyte subsets in renal tissue (G0: no B cells or T cells, G1: scattered B and T cells, G2: clustered B and T cells, G3: an aggregation region of B and T cells without a central network, G4: highly organized and formed zones of B and T cells with a central network of follicular dendritic cells and scattered macrophages), and were further divided into low-grade group (G0+G1), intermediate-grade group (G2) and high-grade group (G3+G4).

Renal fusion anomalies are rare congenital malformations that comprise horseshoe kidney and crossed fused ectopia. Renal tumors arising from these fusion anomalies are anatomically complex, and surgical management can be technically challenging because of altered renal anatomy. Percutaneous CT-guided ablation can overcome some of these anatomical constraints, and microwave ablation has the additional benefit of shorter treatment time and reduced sensitivity to heat sink effects compared to other ablative modalities.

Congenital anomalies are not regularly seen in day-to-day practice. Crossed fused renal anomalies are even rarer. A 50-year-old female patient presented with right-sided pain in the abdomen with intermittent episodes of burning micturition.
