We report a case of intramuscular hemangioma in the subscapularis muscle and the resulting impairment of shoulder function in an adult patient. A nineteen-year-old female complained of shoulder pain and the development of a mass in the absence of previous trauma. Physical examinations, including lift-off and belly-press tests, showed abnormality. X-ray showed multiple calcifications in the front of the scapula. Magnetic resonance imaging showed a soft-tissue mass occupying almost the entire intramuscular portion of the subscapularis muscle. An arthroscopic examination excluded the possibility of a joint invasion, after which the entire mass was successfully removed by open excision. The displacement of the subscapularis by the mass was relieved after the surgery. Pathological diagnosis of the tissue confirmed a cavernous hemangioma. Both shoulder pain and function was improved after operation. There was no evidence of recurrence even at the 2-year follow-up. Rare forms of hemangioma adjacent to the shoulder joint could be successfully managed with surgical excision. Differential diagnosis, such as synovial chondromatosis, pigmented villo-nodular synovitis, and malignant sarcoma, should also be considered.

유골 골종은 골격계의 모든부위에서 발생 가능하지만, 10~20세 남아에서 대퇴골 근위부와 경골의 간부에서 주로 발생하는 것으로 알려져 있고 5세 미만의 소아환자에서 주관절에 발생하는 경우는 아주 드물다. 2세 소아에서 주관절에 발생한 유골 골종은 비정형적인 증상과 방사선 소견 그리고 환자와의 의사소통이 어렵기 때문에 진단이 지연 될 수 있다. 저자들은 2세 여아에서 주관절에 활액막염과 관절내 핵을 갖는 원위 상완골 골간단부에 발생한 유골골종 1예를 치험하였기에 보고하는 바이다.

A 3-year-old, 5.6 kg, castrated, male, British short hair cat presented with subtle weight-bearing lameness of the right hindlimb when walking suddenly after rest. On physical examination, the patient experienced pain when the right stifle joint was hyperextended. There was no clinical improvement of lameness or pain of the right hindlimb, despite the administration of analgesic drugs for one week. During diagnostic arthroscopy of right stifle, mild synovitis and cranial cruciate ligament (CCL) impingement on osteophyte of the intercondylar notch (ICN) was observed. Computed tomography was applied to determine an accurate surgical plan. Arthroscopy-assisted notchplasty, including removal of the osteophyte, was performed using chisel and arthroscopic burr. At 4 weeks postoperatively, the frequency of subtle weight-bearing lameness of the right hindlimb was significantly reduced. At 6 months postoperatively, the patient exhibited normal ambulation without recurrence of lameness. Impingement of CCL may cause subtle lameness and pain. Arthroscopy can be a good diagnostic tool for early-stage CCL disease. Notchplasty can be recommended for osteophyte-induced CCL disease.

Purpose: This retrospective study was designed to determine the type and frequency of associated lesions in patients with chronic lateral ankle instability who had modified Brostrom lateral ankle ligament reconstruction. Materials and Methods: Between 2004 and 2007, 60 cases of 60 patients were enrolled in this study. A retrospective review of the magnetic resonance images of the affected ankle was conducted by two orthopedic surgeons who did not get any information about intraoperative findings and the lesions were admitted when two doctors were coincident. Results: The overall incidence of associated lesions found in this study was about 83%. Peroneal tenosynovitis was the highest frequency (32%), followed by osteochondral lesion of talus (28%), anterolateral impingement (15%), Os subfibula (13%), Os trigonum (12%), ankle synovitis (12%), anterior tibiofibular ligament tear (15%), anterior bony spur (7%). Another findings were loose bodies (5%), flexor tendon tenosynovitis (5%), medial osteophyte (3%). Conclusion: Identifying these associated lesions will be helpful in treating chronic lateral ankle instability especially when the surgeon have a plan to operate the instability. We suggest that the better results can be obtained when the associated lesions are corrected simultaneously.

Epicondylitis, as a tendinopathy characterized by fibroblast and microvascular hyperplasia, is a common musculoskeletal problem especially related with repetitive hand and wrist motion. It has a prevalence of between 0.2% and 5% in general population depending on the amount of exposure to manual labor jobs. Although it is known that the pathological lesions lie in the flexor or extensor common tendons, there could be collateral ligament lesions and/or reactive synovitis accompanied, which may make a case unresponsive to the treatment aimed only at the tendinopathy. Epicondylitis is easy to diagnose with typical pain, tenderness, and positive provocation tests. However, many conditions can mimic epicondylitis that further imaging or electrodiagnostic studies should be undertaken to exclude other possible problems. Ultrasonography provides information about the existence and extent of tendinopathy with relatively high specificity. Magnetic resonance imaging is often required to rule out other problems and confirm the diagnosis of the cases intractable to long term treatment. Many options of treatment are available for epicondylitis while numerous conflicting evidences have been noted, debating one treatment method is better than the others. Since it was reported that over 80% of epicondylitis improved within a year no matter what was done as treatment, it is a challenge to make accurate diagnosis and combine effective therapeutic regimens for the 20% of intractable cases.

Tc-99m-MIBI는 비특이적 반응으로 양성 비종양성 질환의 일종인 활동성 폐결핵에 섭취가 증가되며, 이의 치료 후 추적 관찰에도 유용할 것으로 생각된다. 특히 만성 폐결핵 환자에 있어 방사선학적으로나 객담검사는 음성이었으나 재발이 의심될 때, tuberculin skin test 상 양성이나 단순 흉부 검사상 확실치 않을 때 유용하게 이용되리라 사료된다.

Radiosynovectomy has been used as an effective treatment in patients with resistant synovitis after failure of long-term medication and intraarticular steroid injection. Although $^{90}Y$ silicate/citrate, $^{186}Re$ sulfide, and $^{169}Er$ citrate were approved in Europe for the appropriate radiopharmaceuticals for radiosynovectomy other radionuclides such as $^{32}P$-chromic phosphate, $^{165}Dy$-ferric hydroxide macroaggregate, $^{188}Rh$-microspheres, $^{153}Sm-particulate, and $^{166}Ho$-ferric hydroxide macroaggregate have been used in many countries. Reported success rates range from 40% to 90% for the different joints and underlying disease. In Korea, $^{188}Re$-tin-colloid and $^{166}Ho$-chitosan complex are now using as the major radionuclides in radiosynovectomy with good clinical results. A study on radiation synovectomy using $^{188}Re$-tin-colloid for patients with Korean rheumatoid arthritis shows the treatment resulted in the improvement of arthritis and well tolerated in our study, the radiosynovectomy with $^{166}Ho$-chitosan complex in 53 hemophilic patients markedly decreased intra-articular bleeding frequency and need for coagulation factor. This review inculdes general priciples in the application of radiosynovectomy and the clinical experience in Korea.

A 73-year-old woman presented with a recurrent cystic mass around her left olecranon. She had a history of 8 steroid injections due to elbow pain beginning 3 years ago and twice had undergone aspiration of olecranon bursitis that developed two months prior to presentation. She had been taking medications for hypertension and diabetes with no pertinent past history. On magnetic resonance imaging (MRI), there were multiple nodules in the olecranon bursa, which were isointense to muscle on T1-weighted images and hyperintense to muscle on T2-weighted images. Our initial diagnosis was synovial chondromatosis. On bursoscopy, masses of gray-white colored nodules were observed in the bursa. Finally, synovial chondromatosis and non-tuberculous mycobacterial infection were concurrently diagnosed. In conclusion, uncalcified synovial chondromatosis and rice bodies can have similar visual and MRI characteristics; therefore, we suggest that clinicians should be aware of the possibility of other infections in cases of this type.

Nodular fasciitis (NF) is a benign myofibroblastic proliferation that grows very rapidly, mimicking a sarcoma on imaging. It is treated by local excision, and recurrence has been reported in only a few cases, even when excised incompletely. The most prevalent diagnoses of temporomandibular joint(TMJ) masses include synovial chondromatosis, pigmented villonodular synovitis, and sarcomas. Cases of NF in the TMJ are extremely rare, and only 3 cases have been reported to date. Due to its destructive features and rarity, NF has often been misdiagnosed as a more aggressive lesion, which could expose patients to unnecessary and invasive treatment approaches beyond repair. This report presents a case of NF in the TMJ, focusing on various imaging features, along with a literature review aiming to determine the hallmark features of NF in the TMJ and highlight the diagnostic challenges.
