Abstract
This aim of this article is to provide a comprehensive overview of meniscal tear types and typical
pitfalls encountered in magnetic resonance imaging (MRI) interpretation. Meniscal tears are
common knee injuries that can significantly impact patient outcomes if not accurately diagnosed and managed. MRI is the imaging modality of choice for evaluating meniscal tears due to its high
sensitivity and specificity. However, the interpretation of MRI findings can be challenging, as various
tear types and associated pitfalls can mimic or be overlooked, leading to diagnostic errors and
suboptimal patient care. This article discusses the different types of meniscal tears, including
horizontal, vertical, radial, and complex tears, and highlights the key imaging features and diagnostic criteria for each. Additionally, it addresses the common pitfalls encountered during MRI
interpretation, such as artifacts, partial volume effects, and normal anatomical variants that may
mimic or obscure meniscal tears. By familiarizing radiologists with these pitfalls, this review article
aims to enhance the accuracy and reliability of meniscal tear diagnosis on MRI, ultimately improving
patient outcomes and guiding appropriate treatment decisions.
