Osteochondral fragment perfectly mimicking a meniscal ossicle: imaging and pathology consideration
Meniscal ossicles are small trabecular bone’s structures, often less than 3 cm thick, covered with cartilage, located next to the meniscal cartilages. In the literature there are about 40 publications with 134 reported cases. Since their origin is uncertain and their aspect is aspecific, meniscal ossicles are frequently characterized at imaging mainly by a combination of factors such as their location and their aspect. We present a case of an osteochondral fragment perfectly mimicking a meniscal ossicle to stress out the need of a thorough evaluation of the knee articular space during imaging and the importance of a proper pathology evaluation.
