We report a fortuitously discovered case of renal ptosis in a 9-year-old girl. We take this opportunity to review literature on the embryological, clinical and therapeutic aspects of this malformation, which is the most common renal ectopia diagnosed in sub-Saharan Africa. KEY WORDS: Kidney, Ptosis, Nephroptosis.

The horseshoe kidney (HK) is a very rare renal malformation. It designates a transposition by fusion of the parenchymas of the two poles of the kidney. Its discovery is incidental to an autopsy. However, it is most often asymptomatic. Thus, we report a case of horseshoe kidney accidental discovery in a 58-  year-old man. We take this opportunity to review the literature on embryological, clinical and therapeutic aspects of this malformation, which is one of  the renal ectopies diagnosed in sub-Saharan Africa.
