Kyste mucoïde du ligament croisé antérieur: à propos d’un cas

Abstract

Les kystes mucoïdes du ligament croisé antérieur (LCA) sont rares. Ils sont souvent asymptomatiques et méconnus. Leur expression clinique est polymorphe et c'est l'imagerie par résonnance magnétique qui permet de poser le diagnostic qui est confirmé par l'histologie. La résection arthroscopique constitue le traitement de référence. On rapporte un cas de kyste mucoïde du LCA traité par résection arthroscopique.

The Celery Stalk Sign: An Indicator of Mucoid Cyst of Anterior Cruciate Ligament

“…Mucoid cyst of the anterior cruciate ligament is a rare condition that is often overlooked [1,2]. It is a newly formed cystic formation consisting of one or more cavities containing very viscous mucoid fluid and surrounded by a fibro conjunctive wall [2], described by Bergin et al as an uncommon form of mucoid degeneration [1]. Its prevalence in magnetic resonance imaging (MRI) is 0.4 to 1.3% with a male predominance and an average age between 40 and 50 years old [1].…”

“…Its prevalence in magnetic resonance imaging (MRI) is 0.4 to 1.3% with a male predominance and an average age between 40 and 50 years old [1]. The clinical picture at the beginning is asymptomatic, the evolution is characterized by gonalgia of progressive intensity often posterior in the popliteal fossa [1,2], associated with a limitation of flexion and/or extension with sometimes episodes blocking [1,2]. The physical examination is poor and not very specific, a history of acute trauma or repetitive strain injuries are often involved [1,2].…”

“…The physical examination is poor and not very specific, a history of acute trauma or repetitive strain injuries are often involved [1,2]. Magnetic resonance imaging (MRI) is the gold standard for diagnosis [1,2]. It appears in the form of a cystic lesion, fusiform of liquid signal, filling the intercondylar notch and oriented in the long axis of the anterior cruciate ligament which appears widened in a fan "like a stalk of celery" [1,2].…”

It appears in the form of a cystic lesion, fusiform of liquid signal, filling the intercondylar notch and oriented in the long axis of the anterior cruciate ligament which appears widened in a fan "like a stalk of celery" [1,2]. The evolution can be marked by the rupture of the cyst [1] hence the importance of early diagnosis and adequate management.…”
