Dec 19, 2013 Deutsch A.L.. Discoid meniscus of the knee: MRI imaging appearance. Radiology . 1989; 173: 351-354.

Discoid lateral meniscus is one of the most common knee problems in clinical practice. Several radiographic findings have been reported to screen discoid lateral meniscus, but the diagnostic value of those signs varies.We introduce a new method of measurement on plain radiograph for initial screenin … Discoid meniscus is a spectrum of disorders of meniscal shape and stability that have been classified as complete or incomplete, stable or unstable. In addition to the existing MR imaging criteria of diagnosing tears in nondiscoid meniscus, the presence of increased intrameniscal signal in discoid meniscus along with shape deformation may represent a tear. Discoid meniscus is fairley common in children on clinical examination to come with snapping sounds of the knees.Clinical examination shows a senstivity of 88 % v/s an MRI sensitivity of only 38 % in various series.

This study can create detailed images of the soft tissues of the knee joint and is the best imaging test for discoid The aims of this study are two-fold: (1) To analyse morphological characteristics by magnetic resonance (MRI), and (2) To correlate the size of the meniscus with 23 Feb 2017 Discoid lateral meniscus is a common abnormal meniscal variant in children. Detailed history and physical examination combined with an MRI 15 Mar 2008 MRI is the modality of choice to evaluate a discoid meniscus before surgery.

A discoid meniscus was said to be present if three or more 5-mm-thick contiguous sagittal images demonstrated continuity of the meniscus between the anterior and posterior horns. High-resolution coronal images allowed more graphic depiction of the abnormally wide meniscus.

The ultrastructure of discoid menisci differs from that of normal menisci ; this difference in collagen fiber organization and the stress redistribution Discoid meniscus (DM) is currently considered as a spectrum of disorders in meniscal shape and stability. Diagnosing DM on MR imaging has clinical and surgical implications.

The most prominent distinguishing features of discoid lateral meniscus on plain radiographs include widening of the lateral joint space and a high fibular head. 12,14,15 Additionally, marginal osteophytes and cupping or flattening of the lateral tibial plateau may be revealed. 15 MRI has been shown to be effective in the diagnosis of discoid lateral meniscus. Any of the following factors have been shown to be specific for diagnosis: 1) 14- to 15-mm minimum transverse width of the lateral

At first impression this looks like a tear within a discoid meniscus. At closer look you will notice that the horizontal structure has a lower signal intensity than the meniscus and looks funny. This is a normal variant caused by a vacuum phenomenon. Dr. Ebraheim’s educational animated video describes Discoid meniscus. The meniscus is a cushion structure made of cartilage which fits within the knee joint Ari Youderian, MD, Margaret A. Stull, MD.Discoid lateral meniscus.Applied Radiology.

A discoid lateral meniscus is a common normal variant, occurring in approximately 3-5% of the population. A subgroup of the discoid lateral meniscus known as the Wrisberg variant occurs when there is no posterior attachment of the lateral meniscus. Discoid meniscus (DM) is currently considered as a spectrum of disorders in meniscal shape and stability. Diagnosing DM on MR imaging has clinical and surgical implications. When diagnosing a DM on MR imaging, identification of tears and signs of instability is of utmost importance.

There are 3 varieties – complete, incomplete and wrisberg variant. Discoid Lateral Meniscus; Freiberg's Disease; Evolution; Synovial Osteochondromatosis; MS presenting with severe headache; Rotator Interval Tear; CT IVP; Subdural Haemorrhage Acute on Chronic June (3) May (4) April (14) March (9) February (2) January (9) 2008 (41) RESULTS: For the prospective MR interpretations, the PPV for discoid meniscus was 92%. PPV for discoid meniscal tear was 57%. PPVs for individual types of discoid meniscal tears were 46% (peripheral tear, 19/41), 76% (peripheral tear with horizontal tears, 16/21), 56% (horizontal tear, 5/9), 50% (transverse tear, 1/2), 67% (horizontal tear combined with transverse tear, 2/3), and 100% (longitudinal tear, 1/1).
