Keywords: Lipohemarthrosis, Intra-articular fracture, Knee trauma, Fat-fluid level, Tibial plateau fracture, Musculoskeletal Radiology, Orthopedic Surgery, MRI findings, CT diagnosis Introduction: The Pathognomonic Sign of Occult Trauma In the realm of musculoskeletal radiology and emergency medicine, few signs are as definitive and clinically significant as Lipohemarthrosis . Defined by the presence of marrow-derived fat and blood within a joint space, this phenomenon serves as a sentinel marker for intra-articular fractures. For the astute clinician, identifying lipohemarthrosis is not merely a diagnostic observation; it is a critical pivot point that often reveals fractures that are radiographically occult on initial screening. 1. Pathophysiology: The Mechanical Leakage of Marrow The pathophysiology of Lipohemarthrosis is rooted in the disruption of the bony cortex and the underlying medullary canal. When an intra-articular fracture occurs, the structura...
