Toddler with a left-sided abdominal mass

US and CT of adrenal neuroblastoma
Sagittal US of the left kidney (above left) shows a large, solid, hyperechoic mass superior to the left kidney. Axial CT with contrast of the abdomen (above right) shows an ill-defined solid mass in the region of the left adrenal gland, which (below right) crosses the midline and encases the mesenteric vasculature. Axial CT without contrast of the brain (below left) shows a lytic lesion in the right mandible.

The diagnosis was neuroblastoma arising from the left adrenal gland with metastases to the skull.
