    Insights

    Pelvic fused kidneys, a rare congenital anomaly, are clearly visualized using magnetic resonance imaging (MRI). Coronal plane MRI is crucial for anatomical assessment, eliminating the need for complex reconstructions common in computerized tomography.

    Area of Science:

    • Radiology
    • Medical Imaging
    • Anatomy

    Background:

    • Congenital anomalies of the kidney and urinary tract (CAKUT) represent a significant portion of pediatric diseases.
    • Pelvic kidney, a form of ectopia, occurs when one or both kidneys fail to ascend to their normal retroperitoneal position.
    • Fused kidney anomalies, such as horseshoe kidney, are more common than solitary pelvic kidneys.

    Observation:

    • A case presentation detailing pelvic fused kidneys.
    • Diagnostic imaging modalities employed include intravenous pyelogram and magnetic resonance imaging (MRI).
    • Specific emphasis is placed on MRI's capability in the coronal plane for anatomical visualization.

    Findings:

    • Magnetic resonance imaging (MRI) effectively demonstrates pelvic fused kidneys.
    • The coronal plane of MRI provides direct anatomical insights without requiring image reconstruction.
    • This contrasts with computerized tomography (CT), which often necessitates multiplanar reconstructions for similar anatomical detail.

    Implications:

    • Highlights the diagnostic utility of MRI for complex renal anomalies.
    • Suggests MRI as a preferred imaging modality for pelvic fused kidneys due to its direct multiplanar capabilities.
    • Emphasizes the importance of coronal plane imaging in anatomical assessment of renal ectopia and fusion anomalies.
