Mucoid degeneration of anterior cruciate ligament:MRI features and associated signs
摘要
Abstract
Objective:The purpose of our study was to describe MR appearance and associated sings of anterior cruciate ligament mucoid degeneration. Materials and Methods:We reviewed 4540 knee MRI examinations in 3 years in our practice, all the knee MRI examinations were performed by two 1.5 T magnetic resonance machines. All the MR images were evaluated by two senior musculoskeletal radiologists by consensus. The diagnostic criteria for ligament mucoid degeneration and ganglia and intraosseous cysts based on the prior MRI features and arthroscopy. The incidence of ligament mucoid degeneration, MRI features of ganglion cyst (the size, complexity, location) and associated signs were recorded. Results: Of the 4540 knee MRI examinations, 34 (34/4540, 0.7%) had ACL mucoid degeneration, 13 (13/34, 38%) had discrete mucoid degeneration, and 21 (21/34, 62%) had features of both mucoid degeneration and ganglion cysts. Ganglia were located in the proximal ligament in 18 (86%) examinations and the distal ligament in 2 (9%) and involved the both proximal and distal ligament in 1 (5%). Ganglia ranged in maximum diameter from 6 to 30 mm (mean, 16 mm). 24 (24/34, 71%) cases had intraosseous cysts. 11 (11/34, 32%) cases present with severe osteoarthritis. Conclusions:Anterior cruciate ligament mucoid degeneration demonstrated characteristic“celery stalk sign”on MR imaging and commonly associated with ganglia and intraosseous cysts.关键词
