Renal malrotation along the sagittal plane, with the kidney’s long axis positioned horizontally, represents an exceptionally rare phenomenon, with only three documented cases worldwide.  \nCase presentation: A 45-year-old man with left-sided loin pain arrived at the urology clinic. Non-contrast computed tomography (CT) findings: few calculi in the lower calyx, a massive mid-zonal renal cyst that measured around 8 × 8 × 9 cm, and a sagittally malrotated kidney along its horizontal axis, which was a sign of an acquired ailment rather than a congenital defect.  \nClinical Discussion: Most cases of renal malrotation are identified incidentally during imaging studies, such as CT scans, which are often performed for unrelated reasons, including low back pain, urinary tract infections, or hematuria.  \nMalrotation is often associated with other renal abnormalities, such as ectopia, horseshoe kidney, or other renal anomalies. Conclusion: Malrotated kidneys are uncommon and frequently discovered by accident, particularly those with a horizontal axis in the retroperitoneal space.  \nKeywords: congenital kidney malformation, large renal cyst, malrotated kidney, rare case report, sagittally malrotated kidney  \nIntroduction  \nRenal malrotation is a rare congenital anomaly that can present with various clinical manifestations[1] . Renal malrotation is an uncommon anatomical variation, found in approximately 1 in 939 autopsies and 1 in 390 hospital admissions. During normal fetal development, the kidneys initially form in the pelvis with their hila directed ventrally. Between 6 and 9 weeks of gestation, they ascend to their final position in the renal fossa while undergoing a 90° ventromedial rotation, which ultimately causes the renal hilum to face medially[2] .  \nMalrotation occurs when this natural rotation process is disrupted, resulting in variations such as nonrotation, incomplete rotation, reverse rotation (where the hilum faces laterally), and hyperrotation (where the hilum faces ventrally, laterally, or dorsally). This disruption leads to a rare yet fascinating anatomical anomaly[3].
