Skull in Erdheim-Chester disease. Coloured computed tomography (CT) scan of an axial section through the head of a 28-old patient with Erdheim-Chester disease, showing osteosclerosis and bone erosion at the base of the skull, along with damage to the pituitary gland and pituitary stalk. Erdheim-Chester disease is the abnormal proliferation of histiocyte white blood cells, which causes osteosclerosis - increased bone density.
