Neuroblastoma

FIGURE 118.20. A: Celiac axis neuroblastoma. Computed tomographic (CT) section of the abdomen shows a large lobulated mass with multiple flakes of calcification displacing stomach and the liver (white arrow). Note presence of retrocrural node (black arrows). A, aorta; L, liver; N, node; S, stomach. B: Celiac axis neuroblastoma. Enhanced CT section of the abdomen at level of the kidney shows a large lobulated mass with irregular margins and calcification displacin...

FIG. 10.33. Dumbbell neuroblastoma. A: Magnetic resonance T1-weighted coronal image. Note the small adrenal tumor (arrows) just medial to the ipsilateral kidney. B: A slightly more posterior cut demonstrates the tumor extending into the spinal canal (arrows).

FIGURE 21-41. Neuroblastoma. A. A large, lobulated, hemorrhagic, and cystic tumor, adherent to the upper pole of the kidney, was removed from a child who presented with an abdominal mass. B. A photomicrograph illustrates the characteristic rosettes, formed by small, regular, dark tumor cells arranged around a central, pale fibrillar core.
