A 10-month-old infants present with acute intestinal obstruction. Contrast enema X-ray shows the intussusceptions, likely cause is –
**Core Concept**
The question tests the understanding of **intussusception**, a condition where a part of the intestine folds into the section next to it, often causing intestinal obstruction. This condition is common in infants and is usually idiopathic but can be associated with **lead points** such as Meckel's diverticulum or intestinal polyps.
**Why the Correct Answer is Right**
Since the correct answer is not explicitly provided, we'll discuss the common causes. In infants, particularly around the age of 10 months, **viral infections** are a common trigger for intussusception, possibly due to the formation of a **lead point** like a hyperplastic Peyer's patch in the ileum, which can serve as a starting point for the intussusception.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option text, we can't directly address why it's incorrect, but common incorrect options might include conditions less commonly associated with intussusception in infants, such as certain types of food or other less common lead points.
**Option B:** Similarly, without the text, we can speculate that if it mentioned a condition not typically associated with intussusception, such as a specific type of congenital anomaly not typically linked to intussusception, it would be incorrect.
**Option C:** If this option mentioned an unlikely cause in the context of a 10-month-old, such as a condition more commonly seen in adults or older children, it would be incorrect.
**Option D:** Again, without the text, if it proposed a rare or unrelated condition as the likely cause, it would not be correct.
**Clinical Pearl / High-Yield Fact**
Intussusception is a medical emergency requiring prompt diagnosis and treatment, often with an air or contrast enema, to avoid complications like bowel ischemia. The classic triad of symptoms includes abdominal pain, vomiting, and bloody stools, though not all infants will exhibit all three.
**Correct Answer:** Unfortunately, without the specific options provided, a precise correct answer cannot be given, but typically, the most common cause in infants around this age would be related to viral infections or idiopathic reasons.
