Ectopic Kidney Mimicking Appendicular Abscess.

Area of Science:

• Urology
• Radiology
• Congenital Anomalies

Background:

• Ectopic kidney is a congenital renal malformation characterized by abnormal kidney positioning.
• This condition is often asymptomatic, but pelvic kidneys can present with symptoms mimicking other abdominal pathologies.
• Differentiating ectopic kidney symptoms from adjacent organ conditions is clinically significant.

Observation:

• An 18-year-old female presented with acute right iliac fossa pain and a palpable mass.
• Clinical presentation suggested an appendicular abscess, a common differential diagnosis in such cases.
• Initial assessment highlighted the potential for misdiagnosis due to overlapping symptoms.

Findings:

• Cross-sectional imaging, specifically CT or MRI, was instrumental in accurate diagnosis.
• The patient was diagnosed with pyonephrosis of a right-sided lumbar ectopic kidney.
• Surgical intervention, including nephrectomy, was performed for the infected ectopic kidney.

Implications:

• This case underscores the importance of considering renal anomalies in abdominal pain evaluations.
• Judicious use of advanced imaging techniques is vital for diagnosing ectopic kidney complications.
• Highlighting the diagnostic challenge emphasizes the need for comprehensive differential diagnosis in acute abdominal pain.
