RESUMEN
Bladder duplication is an extremely rare congenital anomaly of the urinary system that is more frequent in boys; the literature is limited to case reports and case series. We describe two cases of bladder duplication in two infant girls with an uncommon variant of complete sagittal septum not included in the Abrahamson classification. The diagnosis was made using magnetic resonance urography, combining excellent anatomical information and static and dynamic evaluation of the urinary tract. The diagnostic information provided by MR-urography was confirmed on surgical exploration. These cases provide an opportunity for paediatric radiologists and urologists to learn more about bladder duplication and improve their diagnosis of this rare condition.

Acute lymphoblastic leukemia is the most frequent cancer in children: it represents 80% of leukemias and about 24% of all neoplasms diagnosed between 0 and 14 years. Acute lymphoblastic leukemia mainly affects children between 2 and 5 years old and in this age group the incidence is about 80-90 cases per million per year. In acute lymphoblastic leukemia, cancer cells multiply rapidly and accumulate in the bone marrow and subsequently invade the blood. However, at the time of diagnosis, leukemia rarely occurs outside the bone marrow or blood vessels and the extramedullary involvement happens mostly in patients with refractory or relapsing disease. In this article, we report an unusual clinical presentation of acute B cell lymphoblastic leukemia with intestinal and ovarian localizations in a 5-year-old girl.
