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.

Discoid meniscus is an abnormality in which the cartilaginous meniscus is differently shaped, thick, and contains less collagen. It is mostly seen in children; and in the adult, it is rarely symptomatic. We have certain knowledge of discoid meniscus shape, its ultrastructure, epidemiology, and pathology. The discoid shape of the meniscus, which is seen mostly on the lateral meniscus, is

Courtesy: Prof Nabil 3D MRI should further improve the diagnosis of meniscal tears. Finally, in the presence of a discoid meniscus, X-rays can identify the relative widening of the Is an MRI necessary? Yes, accurate identification of the discoid meniscus is essential to make sure your child needs to undergo general anesthesia and surgery. Clinical evaluation and MRI identified atypical bilateral discoid medial menisci bilaterally. The patient underwent bilateral meniscal saucerization, with no pain at We had an MRI done, and it was revealed that she had a discoid lateral meniscus but no evidence it was torn.

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. When present, it is bilateral in 20% of cases. Discoid meniscus is seen more frequently in children and adolescents; thus, some authors suggest it may regress in maturity. Etiology The MRI findings of the Wrisberg variant encompass those of a discoid lateral meniscus, which include a specific measurement of the left-to-right width of the meniscus at the center of the body greater than 15 mm on a coronal slice (reference average, 12.8 mm) [3, 4].

It is the least common variant of discoid lateral meniscus and its prevalence has been reported as approximately 0.2% .

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

They are incidentally found in 3-5% of knee MRI examinations.

unaffected knee was obtained in 3 cases, and 1 patient had bilateral discoid medial menisci as well as a unilateral discoid lateral meniscus proven by MRI.

Menisci are present in the knees and the acromioclavicular, sternoclavicular, and temporomandibular joints. A small meniscus is also seen in the wrist joint. 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. 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 lateral meniscus is one of the most common knee problems in clinical practice.

(2003) The clinical importance of meniscal tears demonstrated by magnetic resonance imaging in osteoarthritis of the knee. J Bone Joint Surg Am radiological diagnosis was realized by means of X-ray SPECT-bone scan. All Objectives: The authors report their experience in treating discoid menisci. Medie-/nyhetsföretag.
