Lytic metastasis Neuroblastoma LSBU

Description: Radiology case 448-3318 Two and a half year old boy with an abdominal tumour.
There is a general lytic process, which is most marked in the metaphyses of the femora, but also affects the diaphyses to a lesser degree. Patchy bone loss is also present in the pelvis, particularly pubis and ischium on both sides. The lysis is predominantly a medullary process and undermines the cortex, (scalloping) and has produced a cortical reaction in both femoral diaphyses and above the left acetabulum.
