An unusual case of horseshoe kidney: CT appearance

Area of Science:

• Urology
• Vascular Surgery
• Medical Imaging

Background:

• Horseshoe kidney is a common congenital renal anomaly, characterized by the fusion of the two kidneys at their lower poles.
• This anomaly can be associated with various complications, including urinary tract infections, kidney stones, and an increased risk of certain cancers.
• Understanding its anatomical variations is crucial for surgical planning, especially in procedures involving the abdominal aorta.

Observation:

• A horseshoe kidney presented with an atypical anatomical relationship to the aortic bifurcation during aortic surgery.
• The anomaly was preoperatively diagnosed using advanced imaging modalities.
• The surgical team encountered this rare finding intraoperatively, highlighting the importance of detailed preoperative assessment.

Findings:

• The horseshoe kidney exhibited an unusual spatial relationship with the aortic bifurcation, a finding not commonly reported.
• Ultrasonography and computed tomography (CT) scans successfully identified the horseshoe kidney and its aberrant course prior to surgery.
• The intraoperative confirmation validated the diagnostic accuracy of the preoperative imaging.

Implications:

• This case underscores the variability of horseshoe kidney anatomy and its potential impact on vascular surgery.
• Accurate preoperative imaging is essential for identifying and managing complex renal anomalies during aortic procedures.
• Awareness of such anatomical variations can prevent surgical complications and improve patient outcomes in vascular and urological interventions.
