A patient with rheumatoid arthritis was seen whose main complaint was marked swelling of the shoulders. Surgical exploration revealed the swelling to be secondary to subacromial bursitis; the glenohumeral joint appeared normal.
A 63-year-old man developed symmetrical polyarthritis, subcutaneous nodules at the elbows, olecranon bursitis, and recurrent tenosynovitis. He was later discovered to have idiopathic hemochromatosis. Staining of the subcutaneous nodule revealed iron deposits. These manifestations which are common to rheumatoid arthritis may be seen in hemochromatotic arthropathy.
We present the case of a 40-year-old man with rheumatoid arthritis who had a painless left inguinal mass. Sonographic examination revealed a large soft tissue mass with mixed internal echotexture and regular borders extending inside the pelvis and into the proximal portion of the thigh. Sonography also showed communication between the bursa of the iliopsoas muscle and the hip cavity, with intra-articular synovitis and erosion of the ileum. Giant iliopsoas bursitis secondary to hip involvement in rheumatoid arthritis was diagnosed on the basis of the sonographic findings. This diagnosis was confirmed by MRI.
We report a case of infective iliopsoas bursitis, and to our knowledge a similar case has not been described. The anatomical relation between the bursa and the hip, and related pathological conditions are reviewed. The contribution of CT-guided catheterisation is emphasised as it allows aspiration of fluid, injection of radio-opaque material and lavage.
Synovium-related soft tissue disease around the hip constitutes a spectrum ranging from isolated iliopsoas bursitis to pure articular synovial herniations without bursal involvement. The clinical, pathologic, and radiographic features of these entities are discussed as they pertain to the variety of underlying disorders which predispose to their occurrence. Nine case reports are utilized to illustrate the variable clinical and radiographic presentations which may be encountered. Based upon these cases as well as those in the literature, an imaging algorithm has been developed which should eliminate unnecessary studies and allow prompt and accurate diagnosis.
A case of bilateral deep infrapatellar bursitis is reported in a 19-year-old man suffering from juvenile ankylosing spondylitis and surgically treated for bilateral tibial tuberosity enthesopathy. In addition to erosive non-specific bone remodelling the excised specimens showed, in the bursa, synovial layer hyperplasia with mild subintimal inflammatory cell infiltration, i.e. changes similar to those of synovitis in ankylosing spondylitis. The respective roles of the inflammatory "terrain" and of local shearing stress are discussed.
This is the report of a light and transmission electron microscopic study of an olecranon bursitis and of the adjacent distal tricipital tendon in an 83 year-old man. The data are compared with those of a similar study in the same patient performed 2 years ago. Calcium pyrophosphate dihydrate crystals were observed in the bursal fluid, in the inner part of the bursal wall (extracellular localization and intracellular phagocytosis) as well as in the peripheral part of the tendon. In addition, small apatite deposits were observed in the bursa and tendon by electron microscopy. The origin of these bursal deposits is discussed; it is suggested that they may be related to an exchange from the tendon to the remodelled bursal wall.
A case of bursitis calcarea trochanterica acuta is reported in a boy aged four months. The calcification was amorphous, and arthrography revealed extension into the hip joint. The lesion was treated surgically.
We report the case of a 74-year-old woman who presented with acute-onset right groin pain irradiating to the thigh anteriorly after having suffered for a few weeks from slight knee pain. As a CT scan showed multiple herniated intervertebral discs and spinal stenosis at the L3-L4 level, she was referred to a neurosurgical unit with the tentative diagnosis of L2-L3 radicular pain. Investigations (MR, myelography with CT scan) showed severe acquired lumbar canal stenosis. Decompression surgery was finally postponed because of the patient's serious cardiac medical history and she was referred to us for conservative treatment. She was found to have iliopsoas bursitis with chondrocalcinosis of the knee. Local steroid injections of the two sites abolished her symptoms. We draw attention to the possible pitfalls that the radiographic appearance and one of the multiple clinical presentations of this unrare pathology may represent. Whenever a patient comes walking with crutches, avoids putting weight on his or her leg, and radicular pain is suspected, we advise consideration of other extra-spinal causes for the pain.
Forty-nine patients with Achilles peritendinitis (APT) (11 bilateral) and 31 patients with retrocalcanear bursitis (RCB) (5 bilateral) were treated surgically (altogether 96 heels). There were 37 men and 12 women in the APT group, with a mean age of 38.4 years, and 26 men and 5 women in the RCB group, with a mean age of 32.3 years. Forty-five patients in the APT group and 30 patients in the RCB group were active in sports. All patients had been treated conservatively for at least 6 months (range 6 months to 13 years) without relief of symptoms. The operative method was bilateral longitudinal incision of fascia cruris and trimming of the adhesions to fascia and base of Kager's triangle in APT group, and ablation of the posterior upper corner of os calcaneus in RCB group. In order to assess the ability to return to sports, the healing results were evaluated by questionnaire in 42 patients (47 operations) in the APT group and 25 patients (28 operations) in the RCB group 2-11 years postoperatively. The results were excellent in 27, good in 11, fair in 7 and poor in 2 in the APT group, and excellent in 13, good in 10, fair in 2 and poor in 3 in the RCB group, respectively. Operative treatment of APT and RCB in patients whose symptoms persist after conservative treatment seems to give favourable results in the majority of cases.
The osteoarticular affinity of Streptococcus milleri has only recently been recognized. We report a case of septic prepatellar bursitis caused by this pathogen. The recent literature concerning osteoarticular involvement by S. milleri is reviewed.
Retrocalcaneal bursitis is a distinct condition causing posterior heel pain in active, healthy children. It appears to result from post-traumatic inflammation of the soft tissues of the posterior heel, and is unrelated to avascular necrosis of the calcaneal apophysis. The diagnosis may be confirmed radiographically by the loss of the lucent retrocalcaneal recess, with a normal Achilles tendon and superficial soft tissue contour, and intact cortex of the underlying os calcis.
A 61-year-old woman complained of a subcutaneous mass in her right knee. MR images revealed a well-defined subcutaneous mass in the prepatellar region, containing some fluid and foci of short T2. The lesion showed some marginal contrast uptake after an administration of meglumine gadopentetate (Gd-DTPA), consistent with prepatellar bursitis. The pathological specimen, however, revealed subcutaneous sarcoidosis involving the bursa.
The bicipito-radial bursa, which lies at the biceps tendon insertion on the radial tuberosity, is a rare site of chronic bursitis. We describe the clinical, radiological, and pathological findings in a case complicated by multiple rice body formation. In so doing, we describe MR appearances that allow discrimination of this entity from both synovial chondromatosis and pigmented villonodular synovitis.
A 56-year-old woman with systemic lupus erythematosus developed septic arthritis and bursitis of the left shoulder due to an atypical mycobacterium, M. xenopi. Plain radiography, ultrasound (US), and MRI were performed. Articular disease by tuberculous and nontuberculous mycobacteria have similar presentations, clinically as well as radiologically, and have to be differentiated from other chronic bacterial or fungal infections, pigmented villonodular synovitis, rheumatoid arthritis, gout, hemophilia, and synovial chondromatosis. Although atypical mycobacterial involvement of the skeleton and soft tissues is relatively uncommon, its incidence is increasing, as is the incidence of extrapulmonary tuberculosis in western countries. The triad of Phemister is reemphasized, and the US and MRI findings are demonstrated. The definitive diagnosis has to be made by culturing biopsied synovium or synovial fluid.
This case report describes a patient with acute retrocalcaneal bursitis, which developed after MRI examination of the ankle. The sagittal T2*-weighted gradient echo sequence revealed an extensive susceptibility artifact in the area surrounding the Achilles tendon near its insertion at the os calcis. This artifact was caused by postsurgical metallic particles. We postulate that these particles were mechanically stimulated by the magnetic field and induced the inflammatory response.
We report the imaging features of a 52-year-old man presenting with a groin mass and gross lower limb oedema secondary to venous occlusion by massive cystic enlargement of the iliopsoas bursa 4 years after uncemented primary total hip replacement. Ultrasonography of the groin mass demonstrated a large cystic lesion extending into the pelvis. CT showed displacement of the external iliac vessels with venous compression. Bursography showed the bursa's margins and no communication with the hip joint. Diagnostic aspiration excluded infection, but fluid recollection occurred subsequently. Complete resolution of symptoms, including limb swelling, followed surgical excision with no recurrence at the 5-year follow-up. We believe iliopsoas bursitis occurred as a tissue response to polyethylene wear within the prosthetic hip and occurred even in the absence of loosening or a direct communication between bursa and joint.
Three of 12 nonrheumatoid patients with bicipital radial bursitis had recurrent and recalcitrant symptoms and underwent operative treatment. Preoperative computed tomogram showed an anterior distended synovial cyst at the level of the radial tubercle. Magnetic resonance imaging provided a superb demonstration of a bicipital radial bursa which communicated with the elbow joint below the annular ligament. Surgical exploration revealed a valvular mechanism between the distended bursa and the joint cavity. Excision of the distended bursa and closing the capsular defect lead to excellent results. An antecubital cyst resulting from an acute or chronic tear of the anterior capsule at the sacciform recess may communicate with the bicipital radial bursa and become the cause of recurrent and recalcitrant symptoms.
