Magnetic Resonance Imaging of Cysts, Cystlike Lesions, and Their Mimickers Around the Knee Joint.

Can Assoc Radiol J 2018 May;69(2):197-214

Department of Diagnostic Radiology, Khoo Teck Puat Hospital, Republic of Singapore.

While interpreting routine magnetic resonance imaging (MRI) of the knee joint, a radiologist may encounter various cystic lesions such as ganglion, synovial, and meniscal cysts, among others. In some cases, MRI may demonstrate cystlike lesions around the knee due to fluid distention of normal bursa and recesses, the diagnosis of which should not be difficult if a radiologist is familiar with their characteristic location and MRI appearance. In addition, there are cyst mimickers such as hematomas, abscesses, vascular lesions, and neoplasms around knee joint that may pose a diagnostic challenge on routine MRI. Read More

Cysts and cystic-appearing lesions of the knee: A pictorial essay.

Indian J Radiol Imaging 2014 Apr;24(2):182-91

Department of Radiology, Beth Israel Deaconess Medical Center, Harvard Medical School, 330 Brookline Avenue, Boston MA 02215, USA.

Cysts and cystic-appearing lesions around the knee are common and can be divided into true cysts (synovial cysts, bursae, ganglia, and meniscal cysts) and lesions that mimic cysts (hematomas, seromas, abscesses, vascular lesions, and neoplasms). The specific anatomic location of the cystic lesion often permits the correct diagnosis. In difficult cases, identifying a cystic mass in an atypical location and/or visualizing internal solid contrast enhancement on magnetic resonance imaging (MRI) should raise concern for a neoplasm and the need for further evaluation and intervention.

Baker's Cyst with Intramuscular Extension into Vastus Medialis Muscle.

Knee Surg Relat Res 2012 Dec 29;24(4):249-53. Epub 2012 Nov 29.

Department of Orthopaedic Surgery, Pusan National University School of Medicine, Busan, Korea.

Baker's cysts are one of the most common cystic lesions around the knee joint and mainly caused by fluid distension of the gastrocnemius-semimembranous bursa that is situated along the medial side of the popliteal fossa. Typically, a Baker's cyst extends along the intermuscular planes around the knee joint and may enlarge any direction. However, it is mostly located in the inferomedial or superficial layers of the knee joint and less commonly extends laterally or proximally. Read More

[PTA and stent placement distal to the superficial femoral artery].

Radiologe 2006 Nov;46(11):948-54

Klinische Abteilung für Angiographie und Interventionelle Radiologie, Medizinische Universität Wien, Währinger Gürtel 18-20, 1090 Vienna, Austria.

Although angioplasty and stent applications in the iliac vessels and the superficial femoral artery have become routine procedures, their usefulness for the treatment of lesions of the popliteal artery and the lower leg arteries is still under discussion. For the popliteal artery, limitations are mainly due to the high mechanical stress in this area, causing high traction forces. Moreover, beyond the occlusive atherosclerotic changes, specific pathological entities such as aneurysms, emboli, entrapment syndromes, and cystic adventitial disease have to be differentiated.

Intra-articular ganglia arising from the posterior joint capsule of the knee.

Arthroscopy 2004 Jul;20 Suppl 2:54-9

Division of Sports Medicine, Saitama Medical School, Saitama, Japan.

Magnetic resonance imaging (MRI) is an effective method to evaluate cystic lesions of the knee. Intra-articular ganglia of the knee joint was considered to be rare before the advent of MRI. However, because an MRI is often used to diagnose knee pathology, the reported prevalence of intra-articular ganglia has increased. Read More

Extra-articular soft tissue ganglion cyst around the knee: focus on the associated findings.

Eur Radiol 2004 Jan 25;14(1):106-11. Epub 2003 Jun 25.

Department of Radiology, St Vincent's Hospital, The Catholic University of Korea, 93-6 Ji-dong, Paldal-ku, Suwon, 442-723, Kyounggi-do, South Korea.

The aim of this study was to evaluate MR imaging findings of the associated findings in surrounding tissues of the extra-articular soft tissue ganglion cysts around the knee. We retrospectively reviewed MR images of 30 patients who had surgically confirmed extra-articular soft tissue ganglion cysts around the knee with focus on the associated findings in surrounding tissues, such as muscle, subcutaneous fat, bone, and nerve. The most common associated finding was the visualization of channel between ganglion cyst and the joint, which was demonstrated in 20 cases (continuous type in 12 cases and discontinuous type in 8 cases).
