Discoid meniscus is a rare human anatomic variant that usually affects the lateral meniscus of the knee. Usually a person with this anomaly has no complaints;

findings. diagnosis can be made with 3 or more 5mm sagittal images with meniscal continuity ("bow-tie sign") sagittal MRI will show abnormally thick and flat meniscus. coronal MRI will show thick and flat meniscal tissue extending across entire lateral compartment. Symptomatic cases may reveal underlying meniscus tear. Generally, congenital anomalies affect the lateral meniscus, most commonly a discoid meniscus, although discoid medial menisci can occur much less frequently. We will review the common meniscal variants, which include hypoplastic menisci, absent menisci, anomalous insertion of the medial meniscus, discoid lateral meniscus, including the Wrisberg variant, and discoid medial meniscus. Discoid menisci are seen far more frequently affecting the lateral meniscus than the medial meniscus, the reported ratio of lateral to medial ranging from 15:1 to 4:1.

The thick, abnormal shape of a discoid meniscus makes it more likely to get stuck in the knee or tear. If the meniscofemoral ligament attachment to the femur is also missing, the risk for injury is even greater. Discoid meniscus 䡧On sagittal images, a continuous bow-tie appearance on 3 or more 4 mm slices (12 mm) 䡧Up to 2 mm higher than the opposite meniscus The discoid meniscus is an anatomical variant of the normal meniscus where it is broader and saucer-shaped. There are variations in incidence in various population groups ranging from 0.4-17% for lateral discoid meniscus and 0.1-3 % for medial discoid meniscus. Try to figure out what is going on with this meniscus. Then continue reading. At first impression this looks like a tear within a discoid meniscus.

Discoid menisci of the knee are not uncommon, and the criteria for arthrographic diagnosis and the clinical symptoms are well known. Although enlarged menisci have been recognized at magnetic resonance (MR) imaging, there are no criteria for the MR imaging diagnosis. The authors describe 29 discoid menisci imaged by means of MR. A discoid meniscus was said to be present if three or more 5-mm

Meniscal root tears are often associated with extrusion of the meniscus beyond the margin of the tibial plateau. A meniscus is a crescent-shaped fibrocartilaginous structure that partly divides a joint cavity, unlike articular discs, which completely separate the cavity. Menisci are present in the knees and the acromioclavicular, sternoclavicular, and temporomandibular joints. A … The Wrisberg variant of the discoid lateral meniscus is a rare condition with a highly suggestive clinical history. The musculoskeletal radiologist should consider this diagnosis whenever a discoid lateral meniscus is identified because making this elusive diag-nosis may prove immensely useful for the orthopedic surgeon.

Additionally, the new ratio using the width of the medial meniscus is also useful to to distinguish between incomplete and complete discoid lateral meniscus on MRI 1 Department of Radiology, Samsung Medical Center, Sungkyunkwan&nb

2018-09-24 · A discoid meniscus is a dyslastic meniscus with a disc-like shape usually occuring in the lateral side of the knee. The presence of medial discoid meniscus is extremely rare with an incidence of 0.06%-0.3%, compared to the reported rate of lateral discoid meniscus, which ranges from 1.4% to 15.5% [1, 2, 3]. A discoid lateral meniscus is a not uncommon anatomical variant, found in up to 3% of the population 15.
