What is a hindgut duplication cyst?
Tailgut duplication cysts, also known as retrorectal cystic hamartomas, are rare congenital lesions that are thought to arise from vestiges of the embryonic hindgut.
Do Tailgut cysts need to be removed?
Complete surgical resection is established as the traditional treatment of choice for tailgut cysts because complete resection eliminates the potential for recurrence, hemorrhage, infection, compression, and malignant transformation.
Are Tailgut cysts cancerous?
Although the majority of tailgut cysts are benign, 30% of the reported cases in the literature were malignant [16]. When symptomatic, these lesions tend to be associated with malignant transformation [17].
What is a cyst in the rectum?
A pilonidal cyst (also called pilonidal cyst disease, intergluteal pilonidal disease or pilonidal sinus) is a skin condition that happens in the crease of the buttocks — anywhere from the tailbone to the anus. A pilonidal cyst can be extremely painful especially when sitting.
How common are duplication cysts?
Duplication cysts are rare congenital anomalies of the alimentary tract. The majority of duplication cysts are symptomatic within the first 2 years of life.
What is duodenal cyst?
Duodenal duplication cysts constitute a rare congenital anomaly of the gastrointestinal tract. A recent meta-analysis of the literature between 1999 and 2009 reported a total of 47 cases of duodenal duplication cysts. 3. They form during the embryonic development of the human digestive organs.
Where is Tailgut cyst located?
Tailgut cyst is a rare congenital cystic lesion arising from the remnants of the embryonic postanal gut. It occurs exclusively within the retrorectal space and rarely in the perirenal area or in the subcutaneous tissue.
Where is a Tailgut cyst?
Tailgut cysts are a type of very rare congenital polycystic lesions that are always located posterior to the rectum and anterior to the sacrum.
Do perianal cysts go away?
Perianal abscess may return and require repeated warm water soaks or drainage. However, in most healthy babies, the problem will go away completely at one year of age. For those babies who have repeat infections, there may be a fistula that has formed and is causing bacteria contamination and abscess development.
How do you get rid of a cyst that is duplicated?
The definitive treatment for a duplication cyst is surgery. The surgical approach can be open (laparotomy or thoracotomy) or minimally-invasive (laparoscopic or thoracoscopic) and depends on the expertise of the surgeon. Symptomatic cases: Early surgery is recommended in all the symptomatic cases.
What causes peritoneal inclusion cyst?
As the normal ovary continues to produce fluid and the fluid becomes entrapped by surrounding adhesions, a complex cystic pelvic mass develops (3). Other causes of peritoneal inclusion cysts include trauma, pelvic inflammatory disease, and endometriosis.
What is a tailgut cyst?
Tailgut cyst arises from the embryonic hindgut, embryologically. The embryo possesses a true tail of 8 mm in size, during the human development phases. According to a hypothesis, when tailgut remnants fail to regress, this might lead to tailgut cysts.
How are rectal duplication cysts differentiated from tailgut cysts?
Rectal duplication cysts, the other differential that forms the enteric division, can be easily differentiated from the tailgut cyst by the presence of smooth muscle cells in the cyst wall. It is worth mentioning, that in the pediatric population the most common presacral lesion is a teratoma, which is a form of dermoid cyst.
What is the treatment of choice for tailgut cyst?
The treatment of choice in tailgut cyst is complete surgical removal. However, there are some new surgical approaches as well, which include Transanal minimally invasive surgery (TAMIS). It is minimal invasive excision of the benign cyst. For posterior rectal submucosal lesions, Transanal endoscopic microsurgery (TEM) is a safe option.
Which CT findings are characteristic of cysts on the rectum?
Calcifications may be seen in the cyst wall. When the mass is large, the rectum is displaced by the mass. If concurrent infection or malignant transformation occurs, CT may reveal loss of discrete margins and involvement of contiguous structures.
