INTRODUCTION: Multicystic dysplastic kidney, an uncommon congenital cystic renal disease, is often diagnosed by prenatal ultrasound in the third trimester of pregnancy or in infancy when it commonly presents as an abdominal mass. The typical presentation in childhood is hypertension and/or abdominal mass. However, to the best of our knowledge, the presentation as an abdominal mass in adulthood has not been previously reported, since the renal mass characteristically regresses and is not detectable by age five. Also, the only two cases of this rare condition which were seen in our centre in the past five years, were not found in foetuses or infants, but were rather found in adults and they presented with abdominal masses rather than the common adulthood presentation of abdominal pain and/or hypertension. The imaging features were also not characteristic of multicystic dysplastic kidney.
CASE PRESENTATION: Both patients were Nigerian females of the Yoruba tribe, from the Southwestern part of Nigeria, with ages fifty-five and twenty-four and they presented with abdominal masses. Also, the imaging features were not characteristic of multicystic dysplastic kidney; though they had cystic renal masses, the cysts were communicating.The diagnosis was eventually made on the basis of histology after nephrectomy.
CONCLUSION: Multicystic dysplastic kidney should be considered as one of the differential diagnoses of renal /abdominal masses in adults. Also, all communicating centrally located renal cysts are not dilated calyces.These facts should be noted by urologists and radiologists.
