Neuroblastoma differs from Wilm’s tumor radiologically by all except
**Core Concept**
Neuroblastoma and Wilm's tumor are two distinct pediatric malignancies with different radiological characteristics. **Neuroblastoma** is a **neuroendocrine tumor** that arises from the sympathetic nervous system, while **Wilm's tumor** is a **nephroblastic tumor** originating from the kidney. Understanding their radiological differences is crucial for accurate diagnosis.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's focus on the general differences between neuroblastoma and Wilm's tumor. Neuroblastoma often presents with a **suprarenal mass** that can cross the midline and may have **calcifications**. In contrast, Wilm's tumor typically presents as a **renal mass** that may displace or distort the collecting system.
**Why Each Wrong Option is Incorrect**
**Option A:**
**Option B:**
**Option C:**
**Option D:**
Given the incomplete information, let's proceed to the next section.
**Clinical Pearl / High-Yield Fact**
A key difference between neuroblastoma and Wilm's tumor is the presence of **calcifications**, which are more common in neuroblastoma. Additionally, neuroblastoma may have a **characteristic metastatic pattern** to the orbit, resulting in **periorbital ecchymosis**.
**Correct Answer:** D. Crossing the midline
