Teenager who

tripped and fell and has hip pain. AP radiograph of the hip (upper left) shows a metaphyseal lesion that is expansile and lytic in appearance with a narrow zone of transition and no periosteal reaction. There is a transversely oriented linear density within it representing a fallen fragment sign. Coronal CT without contrast of the hip (upper right) better shows the cystic nature of the lesion and the fallen fragment. Coronal (left lower) T2 MRI without contrast of the hip shows the cystic nature of the lesion and axial T2 MRI (right lower) shows fluid / fluid levels within the lesion due to hemorrhage.The diagnosis was a pathologic fracture through a unicameral bone cyst.

Pitfalls in

the diagnosis of common benign bone tumours in children. Simple bone cyst of the right femoral neck: Frontal (a) and lateral (b) X-rays of the right femur: well-defined central lytic lesion, with internal septa. Transverse T2-weighted MRI (c): a unique, large fluid-fluid level is identified (arrow)
