“…Numerous bursae can be encountered around the knee joint and their primary action is to reduce friction between adjacent moving structures, such as tendons, ligaments and bone surfaces [6–9, 35, 36]. From a histological point of view they are synovium-lined structures and are usually collapsed but may often contain a small amount of synovial fluid.…”

“…From a histological point of view they are synovium-lined structures and are usually collapsed but may often contain a small amount of synovial fluid. Typically are not visible on MRI, unless they are inflamed from various causes (hence the term bursitis) [6–9, 35, 36]. In the following classification, an anatomical location-based scheme (anterior-medial-lateral-posterior) is used for descriptional purposes:…”

“…The deep infrapatellar bursa is located between the posterior margin of the distal part of the patellar tendon and the anterior tibia, beneath Hoffa’s fat pad [1, 2, 6, 8, 35]. There is no communication with the knee joint and is usually inflamed in overuse sports injuries, most commonly in runners and jumpers.…”

Objectives and MethodsA variety of benign cystic or “cyst-like” lesions may be encountered during a routine magnetic resonance imaging (MRI) of the knee. These lesions comprise a diverse group of entities from benign cysts to complications of underlying diseases. In addition, normal anatomic bursae and recesses may be misdiagnosed as an intra-articular cystic lesion when they are distended. However, the majority of the aforementioned lesions have characteristic MR appearances that allow a confident diagnosis, thus obviating the need for additional imaging or interventional procedures.ResultsThis article includes a comprehensive pictorial essay of the characteristic MRI features of common and uncommon benign cysts and “cyst-like” lesions in and around the knee joint.DiscussionFor accurate assessment of the “cystic structure”, a radiologist should be able to identify typical MRI patterns that contribute in establishing the correct diagnosis and thus guiding specific therapy and avoiding unwarranted interventional procedures such as biopsy or arthroscopy.Teaching points• Cystic lesions are common in knee MRI and the commonest, the Baker’s cyst, has an incidence of 38 %.• Synovial cysts, meniscal cysts, normal knee bursae and recesses have characteristic MR appearances.• Miscellaneous “cyst-like” lesions may require a more dedicated MR protocol for a correct diagnosis.

“…Generally, it is difficult to diagnose pes anserine bursitis by physical examination. Use of common diagnostic modalities such as plain X-ray, MRI, and electromyography for the diagnosis of pes anserine bursitis is time-consuming, and injection into the bursa without image guidance is associated with considerable complications [4,5]. In recent years, the ultrasound technique has played a crucial role in increasing the accuracy and efficacy of neuraxial and peripheral nerve blockade as well as joint injection by both decreasing the rate of complications and improving our anatomic knowledge [6-8].…”

Sonoanatomic Variation of Pes Anserine Bursa

et al. 2013

BackgroundThe pes anserine bursa lies beneath the pes anserine tendon, which is the insertional tendon of the sartorius, gracilis, and semitendinosus muscles on the medial side of the tibia, but it can lie in different sites in the medial knee. Accurate diagnosis of the position of the bursa is critical for diagnostic and therapeutic goals. The aim of this study was to evaluate sonoanatomic variations of the pes anserine bursa in the medial knee.MethodsOne hundred seventy asymptomatic volunteers were enrolled in this study. Using ultrasound imaging (transverse approach, 7-13 MHz linear array probe) the sonoanatomic position of the pes anserine bursa and its relation to the pes anserine tendon were evaluated. Additionally, we evaluated the sonoanatomic variation of the saphenous nerve.ResultsThe position of the pes anserine bursa was between the medial collateral ligament and the pes anserine tendons in 21.2%/18.8% (males/females) of subjects; between the pes anserine tendons and the tibia in 67.1%/64.7% (m/f); and among the pes anserine tendons in 8.2%/12.9% (m/f). No significant differences in the position of the bursa existed between males and females. The saphenous nerve was found within the pes anserine tendons in 77.6%/74.1% (m/f) of subjects, but outside the pes anserine tendons in 18.8%/15.3% (m/f). Visibility of sonoanatomic structures was not related to either gender or BMI.ConclusionsUltrasound provides very accurate information about variations in the pes anserine bursa and the saphenous nerve. This suggests that our proposed ultrasound method can be a reliable guide to facilitate approaches to the medial knee for diagnostic and therapeutic objectives.

Prepatellar bursa hematoma is generally caused by direct trauma to the anterior aspect of the knee, resulting in extravasation of blood into a normal bursa. Spontaneous prepatellar bursa hematoma is an unusual entity. Prepatellar bursitis and septic bursitis are the other common causes of a swollen patellar bursa. Bleeding has been recognized as the major complication that limits anticoagulant treatment in patients with prosthetic mitral valve. Here, we present a case of spontaneous prepatellar bursa hematoma in a patient with prosthetic heart valve under warfarin sodium therapy.Key Words: Warfarin; hematoma; bursa, synovial; mitral valve; heart valve prosthesis Mekanik Protez Kalp Kapaklı Bir Hastada Spontan Prepatellar Bursa Hematomu ÖZETPrepatellar bursa hematomu genellikle dizin ön yüzüne gelen direkt bir travma sonucu normal bursa içine gelişen kanama sonucu oluşur. Spontan prepatellar bursa hematomu çok nadir gözlenen bir durumdur. Prepatellar bursit ve septik bursit patellar bursa şişliklerinin diğer önde gelen nedenleridir. Kanama antikoagülan tedavi altındaki protez mitral kapaklı hastalarda tedaviyi kısıtlayabilen majör bir komplikasyondur. Burada; warfarin sodyum tedavisi altındaki protez mitral kapaklı bir hastada spontan prepatellar bursa hematomu sunulmaktadır.
