A right iliac fossa kidney is rarely encountered by the general clinician but multiple diagnoses should be considered.
1. QUESTION
What are the differential diagnoses of a right iliac fossa kidney?
2. ANSWERS
Renal transplant
Supernumerary pelvic kidney
Descended kidney secondary to large inguinal hernia
A renal transplant, accompanied by an overlying Rutherford‐Morrison incision, is preferentially anastomosed within the right iliac fossa (RIF) due to relative ease of access to the iliac vessels. Supernumerary pelvic kidney is rare and more commonly seen on the left. It results from abnormal division of the metanephric cord and can be differentiated from duplex kidney by an independent blood supply. 1 , 2 In this image (Figure 1), a large inguinal hernia has distorted conventional anatomy and the right kidney has descended into the RIF and hernia neck. In this case, the renal hilum is facing anteromedially with a degree of hydronephrosis.
FIGURE 1.
A 78‐y‐old gentleman was seen in the vascular surgery clinic due to peripheral arterial disease. Computed tomography discovered unconventional visceral arrangement. In this case, a large right inguinal hernia has distorted the usual retroperitoneal anatomy and migrated the right kidney to the right iliac fossa, approaching the hernia neck. The right kidney exhibits a degree of hydronephrosis
