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.

Bowel perforation is an unusual complication of ventriculo peritoneal shunt. We are presenting a case of 15 month old male child with the shunt tubing protruding through the anus associated with bowel perforation. This complication occurred after the 13 months of insertion of ventriculo peritoneal shunt for congenital hydrocephalus. There were no signs of meningitis but mild signs of peritonitis were present. At laparotomy the tube was seen to enter the sigmoid colon and was encapsulated by the greater omentum. The tube was cut and the distal end removed via the anus. Proximal part of shunt also removed because there was contralateral shunt present. Perforation was repaired. We are here in presenting a rare complication of VP shunt.

Ventriculoperitoneal shunt (VPS) for hydrocephalus is associated with various complications. Torticollis due to shunt tract fibrosis is a rare complication of VPS that occurs years later after the initial operation. However, shunt track fibrosis that progressed to large neck mass, mimicking sternocleidomastoid tumour and causing torticollis is a previously unreported complication. This led to the restriction of neck movement and hemifacial hypoplasia. Complete excision of the mass restored neck movement.
