Giant Solitary Synovial Chondromatosis of the Temporomandibular Joint with Intracranial Extension

Synovial chondromatosis are rare entities but are well-described lesions in the literature that can affect many joint areas of the body. A case of tumoral synovial chondromatosis involving the temporomandibular joint with intracranial extension through mandibular fossa is reported. As long as there was significant infratemporal and extradural invasion of the middle and posterior fossa, a transtemporal and infratemporal approach was performed and total removal of the lesions was achieved. A brief review of skull base synovial chondromatosis is presented.     

Synovial chondromatosis in a facet joint of a cervical vertebra

STUDY DESIGN: A case report of a cervical facet joint synovial chondromatosis. OBJECTIVES: To correlate the radiologic and histologic features of vertebral synovial chondromatosis with review of the literature. SUMMARY OF BACKGROUND DATA: Only two previous cases of vertebral facet joint synovial chondromatosis were found in a review of the English language medical literature. METHODS: A 39-year-old woman had severe cervical pain associated with neurologic signs and symptoms in the left upper extremity. Computed tomographic and magnetic resonance imaging studies were performed. RESULTS: Imaging studies showed lytic defects in the laminae of C3 and C4, with intermediate T1 and high T2 signal intensities. The diagnostic impression was that of a lymphangioma or synovial cyst. A laminectomy showed synovial tissue in both the C3-C4 facet joint and the lamina bone. Histologic examination disclosed synovial chondromatosis. CONCLUSIONS: Synovial chondromatosis of the vertebral spine is quite rare, this being only the third reported example. Direct invasion of the cancellous bone, as in this case, also is a very uncommon feature of chondromatosis. It is emphasized that when radiologic studies demonstrate a lesion with cartilaginous characteristics within or juxtaposed to a joint, synovial chondromatosis, despite its rarity, should be included in the differential diagnosis, regardless of the anatomic site.     

Synovial chondromatosis of the temporomandibular joint with intracranial extension

A 52-year-old man presented with an extremely rare case of synovial chondromatosis in the temporomandibular joint (TMJ) with extension into the middle cranial fossa manifesting as swelling and exacerbation of pain. He had a long history of right TMJ disorders. Computed tomography and magnetic resonance imaging showed a mass in the right TMJ with extension into the intracranial part through the destroyed temporal skull base. The preoperative diagnosis was chondrosarcoma or osteosarcoma. The patient underwent surgery via combined trans-zygomatic temporal skull base and pre-auricular approaches and the mass was totally removed. Histological examination found an enormous number of closely packed loose bodies of various sizes, consisting of hyaline chondrocytes. The histological diagnosis was synovial chondromatosis. This rare lesion is difficult to discriminate from chondrosarcoma, so total removal is essential for correct diagnosis and cure.     

Synovial chondromatosis of the metacarpophalangeal joint: case report and review of the literature

Intra-articular synovial chondromatosis in the hand is rare but should be considered in the differential diagnosis of a swollen, stiff or painful joint. Other possible diagnoses include osteoarthritis, rheumatoid arthritis, gout, trauma and chronic infection, and unless enchondral ossification of loose bodies is seen the diagnosis of synovial chondromatosis may not be made preoperatively. A 69-year-old man with synovial chondromatosis of the metacarpophalangeal joint is reported. The joint was swollen and tender. He had not sustained trauma and there was no evidence of arthritis, involvement of other joints or infection. Complete synovectomy with removal of all loose bodies was successful and his symptoms resolved. Intra-articular synovial chondromatosis is a benign condition, but spontaneous resolution is the exception and surgical synovectomy remains the most effective treatment.     

Synovial chondromatosis of the metacarpophalangeal joint of the ring finger

Synovial chondromatosis is an uncommon condition, characterized by multinodular cartilagineous proliferation of the joint synovium. There are only a few case reports of synovial chondromatosis involving the hand in the literature. A case of synovial chondromatosis of the ring finger is reported in this paper.     

Asymptomatic Synovial Chondromatosis of the Ankle: An Incidental Finding

Synovial chondromatosis is an uncommon, benign lesion of nodular cartilaginous neoplastic development of the synovium that can lead to loose bodies and arthritic degeneration if left untreated. Although very rare, malignant transformation to chondrosarcoma can occur. Primary and secondary forms of synovial chondromatosis also exist, and each has distinct clinical, radiographic, and histologic characteristics. In this article, we describe a case of extensive primary synovial chondromatosis of the ankle that was asymptomatic until just before presentation, and that was treated by means of open synovectomy with excision of the osteochondromatous lesions within the joint.     

Synovial Chondrosarcoma Arising in Synovial Chondromatosis of the Temporomandibular Joint

Synovial chondromatosis of the temporomandibular joint is rare. Even less commonly documented is the progression of synovial chondromatosis to a synovial chondrosarcoma. The aim of this paper is to present only the third case of synovial chondrosarcoma of the temporomandibular joint. Distinction between these two entities by histology alone is extremely difficult and even though it is advised that the definitive diagnosis should be based on clinical, radiographic and histological evidence, this has proved not to be so simple. The patient, a 63 year old female presented with a swelling associated with her left temporomandibular joint. CT and MRI scans confirmed the presence of a periauricular chondroid mass. Fine needle aspiration biopsy revealed an atypical chondroid lesion that was supicious for a chondrosarcoma. The left temporomandibular joint and surrounding tissues were resected after further imaging and extensive clinical, radiological and cytologic consultations. A diagnosis of synovial chondrosarcoma arising in synovial chondromatosis was made.     

New-Onset Synovial Chondromatosis After Total Knee Arthroplasty

Total joint arthroplasty is commonly recommended as a definitive treatment for synovial chondromatosis refractory to other treatment. We describe a unique case of synovial chondromatosis developing after total joint arthroplasty in a patient presenting 5 years after total knee arthroplasty for osteoarthritis. This case illustrates that the diagnosis of synovial chondromatosis cannot be excluded in a patient with chronic, painful swelling of a joint, even after total joint arthroplasty.     

Synovial chondromatosis of the acromioclavicular joint

Summary Synovial chondromatosis involving the acromioclavicular joint is very rare. We report a case of synovial chondromatosis of the acromioclavicular joint associated with synovial cyst formation. Arthrography of the acromioclavicular joint revealed that the loose bodies lay within a synovial cyst which was in communication with the acromioclavicular joint. Synovectomy including removal of the synovial cyst and the loose bodies relieved symptoms completely. The patient was still pain- and recurrence-free at 4 years' follow-up.     

Primary synovial chondromatosis of the subtalar joint affecting two brothers

Primary synovial chondromatosis is a rare benign condition characterized by the formation of multiple cartilaginous nodules in the synovium of joints and on occasions tendon sheaths or bursae. A case of primary synovial chondromatosis affecting the subtalar joint is reported. The patient's brother developed the same condition affecting the same joint 2 years later. The proposed etiologies are discussed including the presence of the proto-oncogene C-erb B-2.     

Articular synovial chondromatosis of the finger

Abstract

A 40-year-old woman presented with a six-month history of synovial chondromatosis of the metacarpophalangeal joint of the right ring finger, which was resected through both dorsal and volar incisions. To our knowledge there have been only 17 reported cases of articular synovial chondromatosis of the digital joint so far. We present a case affecting the metacarpophalangeal joint with a review of scattered information found in other 17 reports.     

Synovial Chondromatosis of the Shoulder

Articular synovial chondromatosis is a rare disease commonly affecting the knee, hip or elbow, and characterised by the formation of metaplastic cartilaginous foci in the synovium. A case of synovial chondromatosis affecting the shoulder joint is now reported because of the extreme rarity of the disease in this situation.     

Synovial chondromatosis of the pisotriquetral joint producing ulnar nerve palsy

A case of synovial chondromatosis compressing the motor branch of the ulnar nerve of the left hand is presented. Radiographs demonstrated soft tissue calcification. The electrophysiological study confirmed denervation of the intrinsic hand muscles. During surgical exploration, synovial chondromatosis arising from the pisotriquetral joint compressing on the motor branch of the ulnar nerve was seen. Treatment consisted of pisiformectomy, partial synovectomy and removal of loose bodies.     

Arthroscopic treatment of synovial chondromatosis of the ankle

A 34-year-old male soccer player with chronic right ankle dysfunction and a history of repeated ankle joint injuries is presented. Imaging studies revealed synovial chondromatosis of the ankle joint. Arthroscopic partial synovectomy was performed and more than 20 loose bodies were excised. Four months postoperatively the patient was asymptomatic and has returned to his previous level of sport activities. At the latest follow-up, 2 years after the initial diagnosis there is no local recurrence of the disease. Arthroscopy is a minimal invasive surgical technique, with satisfactory results in the treatment of synovial chondromatosis of the ankle joint.

Diagnosis and Arthroscopic Treatment of Primary Synovial Chondromatosis of the Shoulder

Primary synovial chondromatosis of the shoulder is a rare condition. We present the case of a 24-year-old man with a 6-month history of right shoulder pain and decreased range of motion. Computed tomography and magnetic resonance imaging findings led us to the diagnosis of synovial chondromatosis of the shoulder. Arthroscopy revealed loose bodies in the glenohumeral joint, the biceps tendon sheath, and the subscapularis recess. Active intrasynovial proliferation of the axillary pouch was noted. All loose bodies were removed arthroscopically, and partial synovectomy was performed. Histologic examination confirmed the diagnosis of primary synovial chondromatosis. We recommend arthroscopic treatment for synovial chondromatosis of the shoulder because of low morbidity and early functional return.     

Arthroscopic surgery for synovial chondromatosis of the hip: a report of two cases

We have used arthroscopy in the treatment of synovial chondromatosis of the hip joint. Two patients complained of pain of the hip joint that was aggravated by weight bearing. On admission, range of motion of the affected hip joints was slightly restricted. At hip arthroscopy, osteochondral loose bodies were removed from the joint and partial synovectomy was performed. Histologic examination revealed synovial chondromatosis. Pain relief was obtained in both patients postoperatively.     

Vertebral synovial chondromatosis. Report of two cases and review of the literature

Synovial chondromatosis is an uncommon disorder characterized by the formation of multiple cartilaginous nodules within the synovium, most commonly affecting large joints. Its involvement with the spine is rare; only six cases have been reported. The authors describe two patients with synovial chondromatosis involving the cervical spine. In the first case, synovial chondromatosis arose from the left C1-2 facet joint. This patient underwent a two-stage procedure including a posterior approach for tumor resection and occipitocervical fusion as well as a transmandibular circumglossal approach to the anterior craniocervical junction to complete the tumor removal. Interestingly, on histopathological examination, scattered foci of low-grade chondrosarcoma were intermixed within the synovial chondromatosis. To the authors' knowledge, this is the first report of secondary low-grade chondrosarcoma arising in vertebral synovial chondromatosis. In the second case, synovial chondromatosis involved the left C4-5 facet joint. Tumor resection and cervical fusion were performed via a posterior approach. In this report, the authors describe the clinical presentation, radiographic findings, operative details, histopathological features, and clinicoradiological follow-up data obtained in these two patients and review the literature pertaining to this rare entity.
