Figure 1. Gorham-Stout Disease affecting skull base in a child and causing recurrent meningitis. (A) Axial view and (B) sagittal view of bone window showing the lymphatic malformation in central skull base (arrows). Notice the bone is heterogeneous with lysis especially at cortex. (C) Pre-contrast soft tissue window for baseline. Notice the hypodense area next to central skull base (arrows). (D) Post-contrast myelogram. Faint hyper-density in soft tissues next to the central skull base is the leaking contrast from the porous bone (arrows). (E) Spine involvement. Diffuse T1 shortening and T2 prolongation on vertebrae T10-T11, L2 and L4-S1. Majority of these vertebral bodies are nearly completely affected, some with both the anterior and posterior elements involvement.
