Which true about MDC
**Core Concept**
MDC stands for Mesenteric Duplication Cyst, a rare congenital anomaly of the gastrointestinal tract. It is a type of enteric duplication cyst that arises from the mesentery, which is the fold of tissue that attaches the intestines to the back of the abdominal wall. MDC can cause symptoms such as abdominal pain, intestinal obstruction, and gastrointestinal bleeding.
**Why the Correct Answer is Right**
MDC is a type of enteric duplication cyst that arises from the mesentery, which is a fold of tissue that attaches the intestines to the back of the abdominal wall. It is thought to arise from an abnormality in the development of the intestinal tract during embryogenesis. The cyst can cause symptoms such as abdominal pain, intestinal obstruction, and gastrointestinal bleeding due to its location and size.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not describe a characteristic of MDC. MDC is not a type of appendicitis, which is a separate condition.
**Option B:** This option is incorrect because it does not accurately describe the location of MDC. MDC arises from the mesentery, not the appendix.
**Option C:** This option is incorrect because it does not describe the typical presentation of MDC. While MDC can cause abdominal pain and gastrointestinal bleeding, it is not typically associated with the presentation of acute appendicitis.
**Option D:** This option is incorrect because it does not describe the typical treatment of MDC. While surgical resection may be necessary in some cases, it is not the only treatment option for MDC.
**Clinical Pearl / High-Yield Fact**
MDC is a rare but important condition to consider in the differential diagnosis of abdominal pain and gastrointestinal bleeding in children and young adults.
**Correct Answer:** A.
