Crossed fused renal ectopia diagnosed in an adult: Case report.

INTRODUCTION AND

IMPORTANCE

Crossed fused renal ectopia is one of the rare congenital anomalies in which a kidney is found on the side opposite to its normal anatomical location and is fused with the contralateral kidney. Most patients are asymptomatic and diagnosed incidentally.

CASE PRESENTATION: In this case report we present a 60 year old woman diagnosed with a left to right crossed fused renal ectopia with fusion of the left kidney to the inferior pole of the right kidney. The patient presented with vague abdominal pain and diagnosis was made with abdominal ultrasound and CT urography.

CLINICAL DISCUSSION: Though usually asymptomatic, a number of anomalies and complications can be associated with crossed fused renal ectopia including obstruction, stone disease, and tumors. Evaluation and diagnosis usually requires cross sectional imaging. Patients who are asymptomatic and without complications can be managed conservatively.

CONCLUSION

Crossed fused renal ectopia is one of the rare congenital anomalies which can be associated which needs cross-sectional imaging for adequate evaluation. Associated anomalies and complications should be carefully looked for since management depends on it.
