“…Benign periarticular soft-tissue masses uncommonly presenting with internal fat–fluid levels include lymphangiomas and dermoid cysts. [ 12 34 35 36 ] Malignant liposarcoma with an internal fluid component can mimic a fat–fluid level, although an actual fat–fluid level is rare. [ 37 38 ] The presence of floating fat adjacent to an acute bony fracture and the subsequent resolution over time would distinguish extra-capsular floating fat from these masses.…”

Floating fat is a sign of acute bone injury at the knee following trauma. The goal of this article is to review the etiology, patterns, and mimickers of extra-capsular and intra-capsular floating fat, with the major emphasis on knee trauma in the acute setting. We will discuss the spectrum of multimodal imaging findings for rare presentations of extra-capsular floating fat, and contrast these with common and atypical forms of intra-capsular lipohemarthrosis, as an aid to the assessment of acute bone trauma at the knee.

Diagnosis and triage of a patient with an extra-osseous fat fluid level

Extra-osseous fat fluid level is rarely seen in osteomyelitis, with only three magnetic resonance imaging (MRI) cases previously reported in the literature. The rarity of this finding is probably secondary to the extensive necrosis of bone marrow that needs to occur at a rapid phase for the fat to accumulate. However, an extra-osseous fat fluid level is a specific diagnostic sign of osteomyelitis in cases with otherwise equivocal imaging findings and should be reported as such, especially when associated with medullary bone destruction and in the absence of trauma.
