High-resolution ultrasonography has many advantages in the imaging of the musculoskeletal system, when compared to other imaging methods, particularly in superficial, easily accessible parts of the body. It is a perfect diagnostic tool for visualizing the most common pathologies of the musculoskeletal system, including the bursae. Inflammation of bursae is frequent, and it can mimic other diseases of the musculoskeletal system. Therefore, knowledge of normal ultrasound anatomy of the bursae, their exact location in the human body, and the sonographic signs of their most common pathologies is essential for establishing a quick and accurate diagnosis by ultrasound. Common conditions affecting bursae, leading to bursitis, include acute trauma, overuse syndromes, degenerative diseases, inflammatory conditions (rheumatoid arthritis, psoriatic arthritis, gout etc.), infections such as tuberculosis, synovial tumors and tumor-like conditions (pigmented villonodular synovitis, osteochondromatosis), and many more. This review article presents and explains ultrasound examples of the most frequent pathological conditions affecting bursae. Images include normal and pathological conditions of bursae around the shoulder joint, elbow, hip, knee, and ankle joint.

“…Bursae are usually not visible on imaging unless they are irritated or inflamed secondary to trauma, infection, or arthritis. In general, bursae do not connect to the joint space, which distinguishes them from synovial cysts and normal joint recesses [4].…”

Pre-patellar bursitis is one of the major causes of anterior knee pain affecting people between 40 and 60 years of age. It occurs secondary to trauma, infection, overuse, systemic illness, and inflammatory arthropathy. Bursitis can be associated with certain occupations and named accordingly such as pre-patellar bursitis is also known as housemaid knee. Here, we present the case of a 65-year-old female who presented with a visible palpable swelling in the pre-patellar region for 6-7 months which was gradual in onset. Magnetic resonance imaging (MRI) reveals well-defined collection in the pre-patellar bursa along with mild joint effusion. MRI is the modality of choice in this case as it shows high signal intensity on T2 W images and low signal intensity on T1-weighted images. Heterogeneity of the signal is altered when hemorrhage, thickened inflamed synovium, calcification, or loose bodies.

Background: Numerous pathological processes involve synovium and periarticular tissues that are characteristic and in some cases specific to a particular disease. Synovial fluid is a thick, stringy fluid found in the cavity of synovial joint. Examination of the synovium plays a key role in the diagnosis of many joint diseases. Aims: The aim of this study was to study the spectrum of synovial lesions on fine needle aspiration cytology (FNAC) and to compare the cytological diagnosis with histopathological findings. Material and Methods: This retrospective diagnostic analytical study was carried out in the Department of Pathology. Sixty-six patients with suspected synovial lesions referred from other departments who underwent FNAC during 1 year from January 2017 to December 2017 were included in the study. The slides along with records of the patients were retrieved and findings recorded. Histopathological evaluation was performed wherever possible and compared with cytological diagnosis. Results: Non-neoplastic lesions accounted for 80.3% cases followed by benign tumors (15.2%). Ganglion cyst was the commonest non-neoplastic lesion (60.6%, 40/66), while tenosynovial giant cell tumor was the commonest neoplasm (12.1%, 8/66) observed in our study. Solitary case of synovial sarcoma was also observed. Histopathological evaluation was performed in 14 cases and FNAC had overall diagnostic accuracy of 85.7% in diagnosis of these lesions. Conclusions: FNAC is a useful tool with high diagnostic accuracy in the evaluation of synovial lesions.
