Incrusted cystitis is an infrequent process characterized by precipitation an incrustation of salts on the vesical mucosa. An alkanine urine is required to this precipitation.

[Multilocular cysts. An entity of difficult classification. Apropos of two cases]. / Quiste multilocular. Una entidad de difícil clasificación. A propósito de dos casos.

In many occasions, particularly in children, it has been mistaken with a partially differentiated cystic nephroblastoma. Due to the absolute benignancy of the multilocular cyst and the likelihood of preserving the renal parenchyma, we consider of interest to contribute a brief review of the current pathoetiological theories and clinical development, as well as our experience in this disease.
