Resumen de Meniscal ossicle: Cadaveric and imaging cases report
Germán Gutiérrez, Camila Rodríguez, María Ignatov
Meniscal ossicles are small fragments of cancel-lous bone containing bone marrow surrounded by meniscal cartilage. Two cases of meniscal ossicle are reported, one found during routine dissection of the knee joint and the other as an incidental finding on magnetic resonance imaging (MRI). It is a rare entity and is usually located in the posterior horn of the medial meniscus. Cases have been reported since the 1930s in imaging methods. Its association with meniscal tear is common, as it occurred in the reported case. Its origin is dis-cussed, proposing that they may represent vestigi-al remnants of development or that they have a post-traumatic origin. They are usually asympto-matic, being an exceptional cause of knee pain. MRI is the method of choice for its evaluation, al-lowing to distinguish a meniscal ossicle from other intra-articular entities, such as a free body or an intrameniscal calcification. A review of the litera-ture is also presented.
