A few cases with axial skeleton involvement have been reported. Extra-osseous lesions may affect the retroperitoneum, lungs, skin, heart, brain and orbits.

Tout d’abord, la séquence SE T1 doit éliminer d’autres situations (tumeur, infection, nécrose d’origine systémique…), dans lesquelles l’œdème médullaire est un épiphénomène ou n’est pas épiphysaire. Puis les images de haute résolution spatiale en pondération T2 ou densité protonique avec annulation du signal de la graisse permettent d’évaluer le cartilage articulaire, la lame osseuse sous-chondrale et la moelle sous-chondrale : si le cartilage articulaire est anormal, la lésion est irréversible (arthrose ou nécrose) ; si la lame osseuse sous-chondrale est focalement interrompue et/ou si l’épiphyse n’est plus ronde, la lésion est irréversible (nécrose) ; si une zone curviligne et sous-chondrale en hypersignal T2 de type liquidien (dissection sous-chondrale) est visible sous la lame osseuse sous-chondrale de la tête fémorale, la lésion est encore irréversible (nécrose avérée). Enfin, les modifications sous-chondrales peuvent apporter des informations pronostiques utiles : l’absence de toute modification médullaire sous-chondrale autre que l’œdème interstitiel préfigure généralement une résolution spontanée de la lésion et des symptômes ; la présence d’une zone en hyposignal T2 immédiatement accolée à la lame osseuse sous-chondrale suggère une lésion irréversible, surtout si son épaisseur est supérieure ou égale à 4<!--> <!-->mm ou à l’épaisseur de l’interligne articulaire.

Spin echo T1-weighted images are helpful to exclude other underlying diseases (tumor, infection, necrosis from systemic origin…), for which marrow edema is secondary or no epiphyseal in location. High-resolution fat-suppressed T2-weighted or proton density images allow evaluation of the articular cartilage, subchondral bone and subchondal marrow: if the articular cartilage is abnormal, the lesion is irreversible (arthrosis or necrosis); if the subchondral bone is focally interrupted and/or if the femoral is no longer spherical, the lesion is irreversible (necrosis); if a focal linear fluid collection is present under the subchondral bone, the lesion is irreversible (necrosis). Finally, subchondral changes may provide useful prognostic information: the absence of any abnormality other than marrow edema typically indicates that complete resolution is likely; the presence of a focal T2-weighted hypointense lesion immediately next to the subchondral bone suggests an irreversible lesion, especially if it is equal to or thicker than 4<!--> <!-->mm or the joint space.
