On the sagittal fat-suppressed T2-weighted image (7B), fluid extends into the tear. Sagittal proton density-weighted image (5A) through the medial meniscus at age 12 shows the initial horizontal tear in the posterior horn (arrow) subsequently treated with partial meniscectomy. Comparison of Postoperative Antibiotic Regimens for Complex Appendicitis: Is Two Days as Good as Five Days? Clinical History: An 18 year-old male with a history of a posterior horn medial meniscus peripheral longitudinal tear treated with meniscal repair at age 16 presents for MR imaging. bilaterally absent menisci reported by Tolo et al,3 the Medial meniscus posterior horn peripheral longitudinal tear (arrow) seen on the sagittal proton density-weighted image (15A) and managed by repair. Ideal for residents, practicing radiologists, and fellows alike, this updated reference offers easy-to-understand guidance on how to approach musculoskeletal MRI and recognize abnormalities. The example above illustrates marked degenerative changes caused by loss of meniscal function. Sagittal T2-weighted (18B) and fat-suppressed sagittal proton density-weighted sagittal (18C) images demonstrate fluid-like signal in the posterior horn suggestive of a recurrent tear. 2. (PDF) Sensitivity and Specificity of MRI in Diagnosing Concomitant Pullout fixation of posterior medial meniscus root tears: correlation between meniscus extrusion and midterm clinical results. O'Donoghue unhappy triad | Radiology Case | Radiopaedia.org that this rare condition is also clinically asymptomatic. Recent evidence suggests that decreased extrusion may correlate to better clinical outcomes.18. However, clinically significant tears that can mechanically impinge were unlikely to have been missed. Resnick D, Goergen TG, Kaye JJ, et al. published a case series of anterior horn tears of the lateral meniscus in 14 soccer players (mean age 20.2 years). It splits into two bands at the PCL, named Humphry(anterior to the PCL) and Wrisberg (posterior to the PCL). trauma; however, other symptoms include clicking, snapping, and locking The prevalence of a medial discoid meniscus in patients with AIMM menisci develop from this mesenchymal tissue in a site where this tissue After failing conservative management with NSAIDs, PT, and activity modification, he underwent an MRI. On the sagittal proton density-weighted image (11A), signal contacts the tibial surface. The lateral meniscus is more circular, and its anterior and posterior horns are nearly equivalent in size in cross section. Semin Musculoskelet Radiol 2005;9(2):11624, Chung KS, Ha JK, Ra HJ, Nam GW, Kim JG. Bilateral discoid medial menisci: Case report. Efficacy of Arthroscopic Treatment for Concurrent Medial Meniscus of the distal femur and proximal tibia, and in the case report of Examination showed lateral joint line tenderness and a positive McMurray sign. The fat-suppressed sagittal T1-weighted post arthrogram view (7C) demonstrates gadolinium extending into the meniscal substance.
