Abstract:Retroperitoneal teratoma in infancy is exceedingly rare. Progressive enlargement of the abdomen and the presence of an intra-abdominal mass is the most common clinical feature. They constitute third most frequent type of retroperitoneal neoplasm seen in infant and children after Wilm's tumor and neuroblastoma. We report here a case of giant retroperitoneal teratoma in an infant. A 5 month old female child was admitted with complain of abdominal distension. Abdominal CT scan revealed a tumor suggestive of retroperitoneal teratoma. Intraoperative finding revealed that tumor was compressing the atrophic right kidney. Resection of tumor with right nephrectomy was done successfully.

One of the causes of congenital incomplete duodenal obstruction is the presence of congenital duodenal web with fenestration. This condition requires a high index of suspicion for an early and accurate diagnosis. We present an unusual presentation of duodenal web in a 6-year-old girl who presented with a 3-year history of cyclical and seasonal vomiting and abdominal pain. The diagnosis of congenital duodenal web with fenestration was made on contrast study and endoscopy and was treated surgically by incision of the web.

Abstract:The cause of intussusception in most infant is unclear. Intestinal malrotation has been postulated as a possible cause in some infants. The reported case is unusual not only in respect of malrotation associated with intussusception but also because of the presence of mesenteric adenitis and Meckel's diverticulum.
