The differential diagnosis of umbilical polyp includes umbilical granuloma, which is darker red, more apt to bleed, and responsive to silver nitrate cauterization, and also vascular neoplasms, including sarcomas and congenital hemangiomas (Table 1). The umbilical polyp is a rare congenital lesion resulting from the persistence of omphalomesenteric duct (OMD) enteric mucosa at the umbilicus. We also present an overview of the diagnosis and treatment of vitelline duct remnants and their associated anomalies. Cutis. The most common test used to diagnosis urachal anomalies is an ultrasound of the abdomen, bladder and pelvis. The persistence of remnants of the omphalomesenteric duct, within the umbilical cord explains the occasional presence of intestinal tissue. Presentation is commoner in children and rare in adult. We describe the diagnosis and surgical treatment of an infant with an umbilical polyp. This is done in the office of your primary care provider.

A neonatal umbilical polyp may indi-cate the presence of an omphalomesenteric duct remnant. An umbilical-urachal sinus belongs to the spectrum of congenital urachal anomalies and represents a non-communicating dilatation of the urachus at the umbilical end.. Clinical presentation. Also, if the clinical presentation is suspicious, performing an umbilical fistulogram can confirm the diagnosis. Chemical Cauterization for Umbilical Granuloma. It also includes a patent urachus, whose presence is confirmed by the passage of urine through the umbilicus. Ultrasound imaging can be used to identify their relationship and their continuity with the umbilicus and has avoided unnecessary surgical exploration [3]. umbilical polyps, which may look similar to umbilical granulomas, do not respond to silver nitrate. Intestinal polyp . Most urachal problems can be found with a physical exam and ultrasound. The omphalomesenteric duct is the communication between the developing embryonic gut and the yolk sac. An umbilical-urachal sinus can manifest at ultrasound as a thickened tubular structure along the midline below the umbilicus. Treatment . It is a very rare abnormality and may be associated with an umbilical polyp. Ultrasound and / or Computed. Radiographic features. 2005;76:233-235.
