[QxMD MEDLINE Link]. Magnetic Resonance Imaging is the most useful tool for differentiating mucoid degeneration of the ACL from an intraligamentous ganglion or other lesions in the knee joint and if this disease is considered preoperatively, it can be diagnosed easily based on characteristic findings. It is postulated that mucoid degeneration may be a predisposing factor to the formation of ACL ganglion cysts. Mucoid degeneration and ganglia of the ACL demonstrate comparable MRI signal characteristics as well as similar histologic features. in 1999 [3] . Introduction. An ill-defined Its prevalence in magnetic resonance imaging (MRI) is 1.8 to 5.3% , but not all lesions are symptomatic. Magnetic resonance imaging (MRI0 showed a diffuse, thickened ACL with a high inhomogeneous intensity in the T2-weighted and proton density weighted images and which looked similar to a celery stalk. This is a characteristic appearance of ACL mucoid degeneration where the ACL is expanded and hyperintense but is still continuous with normal alignment. Preoperative magnetic resonance imaging (MRI) scan. on magnetic resonance imaging (MRI) ranges from 1.8 to 5.3% [4, 5].
