Cysts and cystic-appearing lesions of the knee: A pictorial essay

“…[1517] These neoplasms include benign intramuscular and juxtaarticular myxomas, as well such malignant sarcomas with myxoid components such as myxoid liposarcomas and myxoid fibrosarcomas. Due to the abundant myxoid matrix, these tumors mimic cysts and appear hypointense on T1W images and extremely hyperintense on T2W images [Figure 25].…”
