A computed tomography (CT) and magnetic resonance imaging (MRI) of the head revealed a large supracerebellar, infratentorial large mass measuring 3.5 x 2.5 x 2.6 cm (Figure 1(a)). He underwent a suboccipital craniotomy with resection of the mass and a ventriculoperitoneal shunt (VP) was placed due to hydrocephalus (Figure 1(b)). CT and MRI imaging of his abdomen were obtained which showed a large pelvic mass with osteoblastic involvement of the bilateral proximal femurs, pelvis, and cervical, thoracic, and lumbar vertebral bodies (Figure 1(c) and (d)).
