2024年3月21日 · There is broad differential for cyst-like lesions around the knee.

MRI is the modality of choice for localizing and characterizing cystic lesions around the knee. The purpose of this work is to present an illustrated review of cystic and pseudocystic lesions of the knee and their characteristics on MRI. Keywords: Cyst, synovial cyst, mucoid cyst, bursae, pseudo-cyst, knee, Magnetic Resonance Imaging.

2013年3月12日 · Medial collateral ligament bursitis (MCL bursitis) The medial collateral ligament bursa lies vertically between the superficial and deep layer of MCL [38–42]. MCL bursitis as an isolated finding is extremely rare, with most cases associated with arthritides and medial intra-articular pathology.

2016年4月2日 · Large meniscal cysts may protrude laterally and may become palpable at the level of knee joint space as a subcutaneous mass (especially on the lateral side of the knee). Meniscal cysts may cause pain, tenderness, and swelling. …

We will discuss the etiology, clinical presentation, MRI findings, and differential diagnosis of various cystic lesions around the knee including meniscal and popliteal (Baker's) cysts, intra-articular and extra-articular ganglia, intra-osseous cysts at the insertion of the cruciate ligaments and meniscotibial attachments, proximal tibiofibular ...

In this study, it was aimed to evaluate the type, frequency and size of cysts observed in and around the knee joint in patients with and without osteoarthritis findings, and to investigate the relationship between these cysts and severity of osteoarthritis.

MR imaging is recognized as the gold standard in characterizing cystic lesions about the knee because of its ability to image the soft tissues exquisitely. MR can confirm the cystic nature of the lesion, evaluate anatomic relationships, and identify associated intra-articular pathology.

2018年5月1日 · On MRI, geodes usually appear as small cystic lesions located in opposing, weight-bearing, subarticular areas around the knee joint, particularly the medial femoral condyle and medial tibial plateau [2] (Figure 25).

MRI showed a large parameniscal cyst (50×15×42 mm) extending medially from the medial joint line, and an accompanying horizontal cleavage tear of the posterior horn of the medial meniscus communicated between the joint space and the parameniscal cyst (figure 2).

2023年4月1日 · Semimembranosus-medial collateral ligament bursitis. The axial (a–d) fat saturated proton density weighted images show a fluid distended semimembranosus–MCL bursa (white arrow). In contact with the semimembranosus-MCL bursa a small Baker cyst is demonstrated (black arrow).
