RESUMO
In children with anorectal malformations (ARMs), it is essential to have a diagnostic imaging method that helps with the evaluation of the internal anatomy. In patients with a persistent cloaca, an ARM variant, in which the measurement of the urethral channel and common channel determines surgical management, there are multiple options for imaging. Magnetic resonance imaging (MRI) is an excellent method for this purpose, from which accurate measurements of channel length can be obtained. Additionally, the use of volumetric/isotropic sequences allows multiplanar reformatting. We present our experience with pelvic MRI and intracavitary non-paramagnetic contrast (MR genitography). This method uses volumetric T2-weighted images and the instillation of saline solution as a contrast agent to distinguish the common channel, length of the urethra, anatomy of the vagina, and presence and location of the rectal fistula. We believe this technique to be particularly useful for those working in settings with limited MRI resources.

Acute pancreatitis is a known complication of choledochal cysts. It is associated with changes in the biliopancreatic junction and with intra-cystic gallstones. We describe a case of pancreatitis and biliary obstruction caused by choledochal cyst type IVa complicated with obstruction by biliary stones in a 2 year old infant.

La pancreatitis aguda es una complicación evolutiva de los quistes de colédoco, se asocia a alteraciones de la unión biliopancreática y litiasis intra-quística. Se describe un caso de pancreatitis y obstrucción de vía biliar por quiste de colédoco tipo IVa complicado por cálculos enclavados, en infante de 2 años...
