Rickets is a disease characterized by a deficiency in bone ossification, affecting the metaphyses, and therefore children during their growth stages, with a common clinical expression even though there are several etiologies, among them the lack of vitamin D3, a rare cause in our subtropical country due to the action of UVB rays. We present the case of a 2-year-old 3-month-old child with bilateral congenital renal hypoplasia who underwent outpatient peritoneal dialysis for CKD starting at 3 months of age. She was admitted to the hospital to be treated for dysfunction of peritoneal dialysis caused by a distal catheter obstruction. On her admission examination, there was evidence of growth retardation and delayed motor development, as well as clinical, radiographic and laboratory signs of active rickets. Blood levels of vitamin D2 very low, which showed this to be a deficiency rickets, She was treated with Calcitriol at 3,000 IU / day, and had a good response to the medication, showing improvement in her bone lesions and motor development, beginning to stand up and taking steps with support.
