“…In the current series, all cases of PVNS were diffuse and MRI showed lobulated margin mass-like proliferative synovium with low signal foci at all pulse sequences due to deposition of hemosiderin in agreement with Patricket al [2]., A. Rodríguez Pan et al [3], and Aynur-Turan et al [4], who reported that the diffuse form PVNS is the commonest form and reported similar imaging appearance.…”

“…Particularly, hemosiderin appears as blooming artifacts on gradient echo (GRE) images because of its magnetic susceptibility, which is almost pathognomonic in all forms of PVNS. Lesions may show evident contrast enhancement after administration of IV gadolinium denoting the synovial proliferation high vascularity [3,4,16,17].…”

“…Simple classification of intra-articular masses as infectious granulomatous diseases (tuberculous and coccidioidomycosis arthritis), noninfectious synovial proliferative processes (synovial chondromatosis, lipoma arborescens, rheumatoid arthritis, pigmented villonodular synovitis [PVNS]), vascular malformations (arteriovenous malformations, synovial hemangioma), deposition disorders (amyloid arthropathy, gout), neoplastic (synovial sarcoma, synovial chondrosarcoma, synovial metastases), and miscellaneous conditions (cyclops lesion following arthroscopic repair of anterior cruciate ligament of the knee) [2,3].…”

Background: Classifications of intra-articular masses are infectious granulomatous diseases, non-infectious synovial proliferative processes (synovial chondromatosis, lipoma arborescens, rheumatoid arthritis, pigmented villonodular synovitis [PVNS]), vascular malformations, deposition disorders, neoplastic, and miscellaneous conditions. The aim of this study is to correlate the results of MRI with arthroscopy in characterization of different varieties of intra-articular synovial masses and mass-like lesions. This observational prospective study was conducted between February 2018 and August 2019. We screened 1000 routine musculoskeletal MRI examination during this period, 32 of which showed intra-articular synovial masses/mass-like lesions. The selected 32 patients (20 males and 12 females) have a mean age of 49.20 ± 2.0 years; all presented with joint swelling, pain, or difficulty of movement according to the joint affected. All patients underwent arthroscopy for histopathological correlation. Results: The final diagnosis was synovial chondromatosis in 14 patients (43.8%), PVNS in ten patients (31.3%), and lipoma arborescens in five patients (15.6%). Synovial chondrosarcoma, synovial hematoma, and synovial ganglion cyst each in one patient (3.1%). The concordance of MRI to arthroscopy was 96.6% accuracy, 91.7% sensitivity, 99% specificity, 52.3% PPV, and 99.9% NPV. Conclusion: Good correlation was observed between MRI and arthroscopy in diagnosis of intra-articular synovial masses/mass-like lesions.

“…Ganglia appear on MRI as lobulated, rounded, well-limited fluid collections. However, it is not always easy on MRI to distinguish a ganglion cyst from a giant cell tumor of synovial sheath or sarcoma [ 4 , 11 ]. USG can be useful to show the cystic structure of the lesion and differentiate them from solid tumors.…”

“…Although drop foot secondary to peroneal nerve damage is mostly seen after acute injuries such as trauma, it may also develop on a chronic basis. Peroneal nerve palsy (PNP) may result from tumors (sarcoma), hematoma, and cysts [ 3 , 4 ]. As far as we know, in 1921, Sultan reported the first case of compression of the peroneal nerve by a synovial cyst [ 5 ].…”

Ganglion cysts are masses that we encounter frequently in our daily practice, usually in the upper extremity, less frequently in the lower extremities, and rarely cause compression symptoms. We present a case of a massive ganglion cyst of the lower limb causing peroneal nerve compression, managed with excision and proximal tibiofibular joint arthrodesis to prevent recurrence.Examination and radiological imaging of a 45-year-old female patient who was admitted to our clinic showed new-onset weakness in right foot movements and numbness on the dorsum of the foot and lateral cruris, a mass consistent with a ganglion cyst expanding the muscle was detected in the peroneus longus muscle. In the first surgery, the cyst was carefully resected. After three months, the patient came with a repeated mass on the lateral side of the knee. After confirmation of the ganglion cyst with clinical examination and MRI, a second surgery was planned for the patient. In this stage, we performed a proximal tibiofibular arthrodesis for the patient. Her symptoms recovered during the early follow-up period and no recurrence occurred during the two years of the follow-up period.Although the treatment of ganglion cysts seems easy, it can sometimes be challenging. We think that arthrodesis may be a good treatment option in recurrent cases.
