FIG. 49.27 Neuroblastoma With Intraspinal Extension. This 4-week-old girl had rectal prolapse. Initial imaging included spinal sonography.

(A) and (B) On sagittal views (oriented to match magnetic resonance image), a homogeneously echogenic mass was discovered within the lumbar

vertebral canal (straight arrows) and protrudes through the neural foramen (curved arrow). (C) Corresponding T2-weighted magnetic resonance

image shows hypointense intraspinal lumbar mass (black arrows). Corresponding transverse sonogram (D) and magnetic resonance image (E)

show the dumbbell-shaped mass with an intraspinal component and paraspinal/retroperitoneal extension (arrows). (F) Axial ultrasound shows

intraspinal component (calipers). (G) Coronal T2-weighted magnetic resonance image reveals the intraspinal mass compressing the conus medullaris

and extension into retroperitoneum.
