Diverticulosis appearance on barium enema as shown is called:
**Diverticulosis on Barium Enema**
=====================================
**Core Concept**
---------------
Diverticulosis refers to the formation of diverticula, which are small, bulging pouches in the wall of the large intestine (colon). On a barium enema, these diverticula can be visualized as outpouchings of the colonic lumen.
**Why the Correct Answer is Right**
---------------------------------
The appearance of diverticulosis on a barium enema is characterized by the presence of multiple small, rounded or oval outpouchings along the colonic wall. These outpouchings are typically 1-3 cm in size and are most commonly seen in the sigmoid colon. The barium fills these outpouchings, creating a characteristic "thumbprinting" or "sacculated" appearance.
**Why Each Wrong Option is Incorrect**
--------------------------------------
* **Option A:** This option is incorrect because it does not describe the typical appearance of diverticulosis on a barium enema. While diverticulosis can cause narrowing of the colonic lumen, this is not the characteristic feature seen on imaging.
* **Option B:** This option is incorrect because it describes the appearance of a colonic polyp, which is a different entity from diverticulosis.
* **Option C:** This option is incorrect because it describes the appearance of a colonic tumor, which would be a more irregular and asymmetric mass.
**Clinical Pearl / High-Yield Fact**
----------------------------------
Diverticulosis is a common condition, affecting up to 50% of individuals over the age of 60. It is often asymptomatic but can cause symptoms such as abdominal pain, constipation, and changes in bowel habits.
**Correct Answer:**
Diverticulosis appearance on barium enema as shown is called **Diverticulosis**.
