Collecting duct carcinoma of the renal medulla presenting with paraplegia.

We report an interesting case of a patient with collecting duct carcinoma arising from the left kidney who presented with paraplegia secondary to metastases. The diagnosis was based on CT and histology. To our knowledge this is the first case of collecting duct carcinoma to present with paraplegia. The literature review also highlights the rarity of this disease with less than a hundred cases reported to date and the aggressive nature and poor prognosis despite prompt interventions.
