Tubulocystic carcinoma of kidney: A challenging diagnostic entity mimicking multicystic kidney
and presenting with bone metastasis.
The differential diagnosis of a cystic mass located between the kidney and the spine includes urinoma, lymphangioma, hemorrhagic neuroblastoma, mesenteric cyst, enteric duplication, multicystic kidney
disease, polycystic kidney disease and ureteric duplication.

It is worth noting that the often-quoted rate of vesicoureteral reflux up to 43% from the Multicystic Kidney
Registry is prone to selection bias as only 15% of patients in the registry had a voiding cystogram.
For example, multicystic kidneys
erroneously called MCDKs were proven to be examples of GCKD instead.
