    Radiolucent multiloculated lytic lesion in the proximal tibia.

    answer - it's a pigmented villonodular synovitis that decided to invade the tibia rather than grow into the joint space

    Differentials

    Giant cell tumor ( although in classical giant cell the margin is more distinct )
    Aneurysmal bone cyst
    Simple bone cyst
    chondrosarcoma
    chondroblastoma
    chondromyxoid fibroma
    giant cell reperative granuloma
    brown tumor of hyperparathyroidism
    enchondroma ( why not ? )
    and the list goes on
