“…Fluid-fluid levels are a relatively specific finding for an aneurysmal bone cyst and are due to blood sedimentation of various ages [ 8 ]. When fluid-fluid levels occupy greater than two-thirds of the lesion, this finding is highly specific for an aneurysmal bone cyst [ 9 ]. Fluid-fluid levels may also occur in telangiectatic osteosarcomas, unicameral bone cysts, giant cell tumors, and chondroblastomas [ 9 ].…”

Fluid-fluid levels may also occur in telangiectatic osteosarcomas, unicameral bone cysts, giant cell tumors, and chondroblastomas [ 9 ]. Additionally, the absence of fluid-fluid levels on MRI does not exclude a diagnosis of an aneurysmal bone cyst, as this finding may only be present in 30-44% of cases [ 10 ].…”

“…Estão presentes preferencialmente nos ossos longos (5,9). A principal característica dessas lesões é a presença dos níveis líquido-líquido os quais são resultado da diferença de densidade do componente celular hemorrágico e do plasma, o menos denso (10). São observados nos exames de ressonância magnética (9) e de tomografia computadorizada (11).…”

“…: crianças e adultos jovens com lesões contendo volume aneurismático > 2/3 eram provavelmente benignas; pacientes > 50 anos que apresentavam lesões aneurismáticas com volume < 2/3 eram provavelmente malignas e tumores malignos eram frequentes em indivíduos com mais de 50 anos sendo a maioria metástases(10).4. Tipo de destruição óssea:Os critérios de Lodwick(38) (1980) descrevem a maior ou menor agressividade dos tumores ósseos nos exames de imagens: Lesão IA, bem delimitada e com margem esclerótica; lesão IB, bem delimitada, margem pouco esclerótica e com afilamento da cortical; lesão IC, mal delimitada, pouco ou nenhum halo de esclerose, ruptura da cortical; lesão tipo II moteada ou roído de traça e lesão tipo III permeativa.…”
