The lateral meniscus is discoid, with no abnormal signal identified to suggest the presence of a tear within.
The medial meniscus is unremarkable, with no tear or parameniscal cyst seen.
Case Discussion
Discoid menisci are anatomical variants that have a body that is too wide, usually affecting the lateral meniscus with a higher risk of tearing compared to a normal meniscus. They are incidentally found in 3-5% of knee MRI examinations.
