Renal allograft transplant recipient with ruptured hydatid native kidney.

Echinococcosis of the kidneys in a renal transplant recipient is extremely rare and its occurrence being related to immunosuppression is a possibility which needs further characterisation. Ruptured renal hydatid in a renal transplant recipient is not reported so far to our best knowledge. We present a 42-year-old renal allograft receipient who presented one year after transplant with left flank pain, palpable left lumbar mass and gross hydatiduria. Investigations revealed a ruptured native hydatid kidney. Patient was managed with a combination of chemotherapy and left native nephrectomy and discharged in a satisfactory condition.
