From: Coccidiomycosis infection of the patella mimicking a neoplasm – two case reports
A contrasted knee MRI had been performed at an outside facility (A: Sagittal T1 proton density (TE 34; TR 1967); B: Sagittal T2 with fat saturation (TE 54; TR 3067); C: Coronal T2 with fat saturation (TE 59; TR 2733); D: Gadolinium enhanced Sagittal T1 with fat saturation (TE 10; TR 533)). This demonstrates knee joint effusion with extensive synovitis involving Hoffa’s fat (arrow: A, B, D) and continuity with the osteolytic area within the inferior pole of the patella. There is abundant adjacent bone marrow edema within the patella (B, C) and proximal tibia (B).
