Axial T1 postcontrast volumetric imaging from a radiation-planning MR imaging for a metastatic melanoma lesion (A, arrow) demonstrates a 2-mm enhancing focus posterior to the left vertebral artery in the foramen magnum (B, arrow). This was unchanged from a study 18 months earlier (C, arrow) and was seen on a venous phase soft-tissue neck CT (D, arrow). Thin-section postcontrast imaging reveals its close proximity to a barely perceptible upper cervical nerve root (E, dashed arrow). A presumably coincidental developmental venous anomaly is seen in the left cerebellar hemisphere (F, black arrow).
