Meniscal and ganglion cysts frequently present as palpable masses of the knee but occur at different locations than do popliteal cysts. Meniscal cysts also may be discovered incidentally on studies performed for suspected internal derangement. Sixteen cystic lesions of the knee were evaluated with MR, including 11 meniscal cysts and five ganglion c...

... 9 The investigation of choice for any cystic lesion in the knee is MRI. 10 MRI not only provided the correct diagnosis but, in revealing the location of the extension, also provided the correct surgical approach for excision According to Recht et al. 11 Ganglion cysts may have following differential diagnoses of ganglion cysts may include synovial chondromatosis, pigmented villonodular synovitis, meniscal or parameniscal cysts, and synovial hemangioma. 4 Before the use of arthroscopy, intra-articular ganglia were excised by means of an arthrotomy. ...
A 23 year old female presented with knee swelling which was found to be ganglion cyst of the knee with extra synovial and intracapsular origin form the lateral meniscus which was causing pain in extreme extension. The cyst was excised and confirmation was done on histopathology. Ganglion cysts may have following differential diagnoses of ganglion cysts may include synovial chondromatosis, pigmented villonodular synovitis, meniscal or parameniscal cysts, and synovial hemangioma. Which needs good histopathological and radiological correlation. Most common sites of Intra-articular ganglion cysts are in the dorsal wrist, palm, and shoulder but rarely found in the knee joint.
... 2,3 The incidence of ACL ganglion cysts is between 0.6% and 2% in arthoscopic studies and between 1 and 1.3% on magnetic resonance imaging (MRI) studies. [4][5][6][7][8][9] One of the reasons for this low prevalence is assumed to be the asymptomatic nature of these cysts. Indeed, only 10% of cases are symptomatic, and these patients present with vague pain in the knee, unexplained knee effusions, or limitations to activity without any history of real trauma. ...
... The prevalence of intra-articular ganglion cysts in the ACL is considered to be rare. 3,4,[6][7][8] Moreover, the large majority of these cysts remain asymptomatic, and only 10% of cases manifest symptoms, such as vague knee pain, limitation of range of motion or even recurrent effusions. 2,3,5,[8][9][10][11] The exact cause and pathogenesis of ACL ganglion cysts still remain unclear. ...
The incidence of intra-articular ganglion cysts of the anterior cruciate ligament (ACL) is low and symptomatic presentation of this pathology is even lower. Nevertheless, symptomatic cases pose a real challenge for the orthopaedic community, as no general consensus exists regarding the most appropriate treatment. The purpose of this Technical Note is to describe the surgical treatment of an ACL ganglion cyst by arthroscopic resection of the entire posterolateral bundle of the ACL in a figure-of-four position after conservative treatment has failed.
... It was previously reported that meniscal and ganglion cysts can present as palpable knee swelling (26) . In the present study, the meniscal cyst was the second most frequently encountered cystic lesion followed by ganglion cyst and in concordance, with former studies (1,4,(27)(28)(29) both were more prevalent in young males with a male: female ratio of 4:1 and 3:1, respectively and slight predominance of right knee involvement. ...
... Subacute (1-3 months old) hematomas are usually T1 and T2 hyperintense. The high T1 signal intensity, caused by methemoglobin, may initially be seen in the periphery [83]. Chronic hematomas are T1 and T2 hyperintense but can have a prominent hypointense rim representing a wall of fibrous tissue and/or hemosiderin. ...
Soft-tissue tumors account for less than 4% of all tumors in adult patients and 7-10% of all tumors in pediatric age group. The majority of these tumors are benign in nature (more than 99%). Different imaging modalities play a significant role in the diagnosis, treatment, and follow-up of these tumors. In this chapter, we will try to cover the imaging appearances of different benign soft-tissue tumors and to demonstrate the differentiation features. In addition, we will demonstrate a systematic approach for the characterization of soft-tissue masses based on different imaging appearances.

... A study, assessing extra-articular ganglion cysts around the knee joint found that also these lesions have a high incidence of intra-articular pathologies (69.6%) and that only 43% of the extra-articular ganglion cysts showed connections to intra-articular, which shows the rare character of this pathology [1]. MRI of the knee is of utmost importance in order to detect the extent of the lesions as well as communication to intra-articular as failure to remove the intraarticular connection surgically can lead to reoccurrence [10][11][12]. The presented case showed a multilocular ganglion cyst system around the right knee-joint and MRI revealed connection to intra-articular. ...
Introduction: Extra-articular soft tissue ganglion cysts of the knee occur very rarely. We present a case of a lateral anteroinfe-rior cystic ganglion system with communication to intra-articular in a 61-year-old female. Presentation of Case: 61-year-old female with extra-articular cyst formation on the anterior inferolateral right knee. Open exci-sion of the ganglion system as well as closure of the intra-articular portal has been performed in combination with diagnostic arthroscopy and resection of concomitant intra-articular pathologies. The patient recovered well, and no re-occurrence has been detected. Discussion: MR-imaging remains the gold standard for diagnosing extra-articular ganglion cyst formations to detect intra-articular connection. Open surgical exploration, excision and closure of the intra-articular portal has been suggested in order to prevent reoccurrence. Concomitant intra-articular lesions should be addressed arthroscopically. Conclusion: Adequate pre-operative imaging is of utmost importance. Extra-articular ganglion systems should be explored surgically and portal to intra-articular should be closed. To assess intra-articular pathologies, arthroscopy is suitable.
... In the differential diagnosis of intraarticular ganglion cyst ; pigmentary villonoduler synovitis, hemangioma, fibroma, myxoma, aneurysm and intra-articular lipomas should be kept in mind (5). Contrast-enhanced computed tomography or ultrasound can be applied for differential diagnosis, but CT and USG can be limited to evaluation for knee, so MRI is the primary method of diagnosis (4). ...
Anterior and posterior cruciate ligaments associated ganglion cysts of knee are rare conditions. These cysts are generally symptomatic ; painfull and activity limiting. MRI is commonly used for diagnosis of cruciate ligaments associated ganglion cyst, relation to anatomical structures and preoperative assesment. In this study, we present 8 cases with ganglion cysts in the cruciat ligaments detected with MRI and treated conservatively or arthroscopically. Three of these cases were treated conservatively and five of cases were treated arthroscopically. One of the patients treated conservatively had moderate pain and seven patients had no pain or any other symptoms.
... A ganglion is a benign cystic mass containing clear high-viscosity mucinous fluid with a dense fibrous connective tissue capsule lined by flat spindle-shaped cells that is rich in hyaluronic acid and other mucopolysaccharides [1,2]. Ganglia usually arises from periarticular locations with a variable for predilection intra-articular, extra-articular soft tissue, intraosseous and rarely from periosteal locations [1,3,4]. ...
Cystic lesion around knee usually presents as painless swelling and diagnosed incidentally by imaging for any internal derangement of the knee. Few cases presented with pain. Intra-tendinous patellar ganglion is very rare in location for the disease. Ganglionic cyst usually treated by aspiration followed by steroid and surgical excision in some cases. We reported a case with anterior knee pain due to patellar intra-tendinous ganglion cyst which treated conservatively with no recurrence even after one year.
... [6] Classically, Baker's cysts are described as fluid-filled cystic lesions that do not contain a true synovial lining. [7] The cyst contains synovial fluid, which is typically gelatinous in consistency. They are located posteriorly the knee as a fluid filled sac with a neck arising from the interspace between the medial head of gastrocnemius muscle and the semimembranosus tendon. ...
The presentation of unilateral leg swelling is commonly encountered clinical practice, with deep vein thrombosis (DVT) often raised as the main diagnosis. Not infrequently, and at times unexpectedly, a different pathology can be encountered. It is important to be aware of other causes of the unilateral swollen leg to avoid unnecessary anticoagulation and potential missed diagnosis. This article provides a systematic approach, with a review of the imaging characteristics, of the most common etiologies that can cause unilateral leg swelling mimicking a DVT.
... Meniscal cysts are a relatively uncommon occurrence that may result in pain and disability in the knee. ere are many possible etiologies for meniscal cysts, but it is widely believed that these cysts arise secondary to uid extrusion through a meniscal tear [1]. Meniscal cysts may be found in either of the meniscus. ...
