Purpose : Recently ultrasound images has been used to measure the subacromial space with a linear measurement of the acromiohumeral distance. The purpose of this study was to comparison of distance of subacromial space using ultrasonographic measurement on arm positions of shoulder injured patients. Methods : The subjects were 30 shoulder injured patients (19 males and 11 females). Ultrasonography was performed to measure subacromial space during each shoulder resting position, $45^{\circ}$ abduction, internal rotation with $45^{\circ}$ abduction and external rotation with $45^{\circ}$ abduction. Results : Subacromial space was a significantly difference between injured arm and normal arm at shoulder resting position. At $45^{\circ}$ abduction, subacromial space was narrowing significantly between injured arm and normal arm. At external rotation with $45^{\circ}$ abduction, subacromial space were wider in normal arm than in injured arm but it was not significantly. Intra-observer reliability for ultrasonography measurement of subacromial distance was excellent (.96~.99). Conclusion : These results identified that positions of injured shoulder was related to subacromion space.

음낭 내에 발생한 경화지방육아종은 매우 드문 질환으로 지방조직의 이물반응에 의해 발생하는 것으로 알려져 있다. 주로 음경 및 음경음낭이음부에 발생한 임상적 보고 및 음낭 내 발생한 초음파 소견에 대한 증례 보고는 있었지만 저자들이 아는 한도에서는, 음낭 내 경화지방육아종의 자기공명영상 소견에 대하여 자세히 보고된 바는 없었고, 특히나 영문으로는 본 저자들이 탈장성형술 후 발생한 음낭 내 감염성 경화지방육아종에 대해 처음 보고하는 바이다.

The diagnosis of a gluteal muscle tear or strain is based on clinical findings. However, for an accurate diagnosis, imaging examinations are also needed. Herein, we describe the case of a patient with a gluteus maximus muscle tear confirmed by ultrasonography (US) and magnetic resonance imaging (MRI). A 58-year-old woman complained of dull pain in the left lateral gluteal region that she had been experiencing for 8 days. In the axial US image, retraction of the left gluteus maximus muscle was noted around its insertion site in the iliotibial band. On an MRI, a partial tear in the left gluteus maximus was observed at its insertion site in the left iliotibial band. In addition, fluid infiltration due to edema and hemorrhage was observed. A partial left gluteal muscle tear was diagnosed. The patient was treated with physical therapy at the involved region and oral analgesics. She reported relief from the pain after 1 month of treatment. Based on this experience, we recommend US or MRI for accurate diagnosis of muscle tear or strain.

목적 : 측두하악장애 환자에서 고가의 자기공명영상 진단을 대신하여 상대적으로 경제적인 진단방법으로 고해상도 초음파 영상을 도입하는데 있어서 그 정확성과 유용성을 확인하고자 하였다. 방법 : 측두하악장애의 임상적 증상 중 과두걸림, crepitation과 함께 통증을 호소하는 20명의 환자를 대상으로 하였다. 고해상도 초음파 촬영을 시행하였고, 고해상도를 가진 초음파촬영시의 결과를 비교하기 위하여, 통상적인 방사선 사진인 측두하악관절의 횡두개 촬영을 Accurad X-200으로, 그리고 Dental CT를 촬영하였으며, 이를 임상소견과 더불어 비교항목으로 선택하였다. 고해상도 초음파의 진단학적 가지 평가를 위하여 통계학적으로 감수성, 특이성, 양성예상치, 음성예상치 및 정확도를 계산하였다. 결과 : 고해상도의 초음파 영상은 골관절염성 변화를 진단하는데 67.5%의 정확도를 보였으며, 관절원판의 위치변화를 진단하는데 92.5%를 보였으나, 관절 주변조직인 관절낭, 관절원판 후조직 그리고 주변 인대의 이상을 측정하는데 있어서 정확도가 55%를 나타내었다. 결론 : 향후 초음파 영상을 얻기 위한 적절한 기기의 발전과 고주파수의 transducer 등이 개발되고 시술자의 훈련과 경험이 쌓이게 되면 매우 우수한 그리고 비침습적이고 접근이 용이하며 경제적인 진단학적인 검사방법으로서 일반적인 도입이 가능할 것으로 사료된다.

Background: The incidence rate of thyroid cancer has been increasing worldwide in recent years, and it is also the most prevalent cancer when it comes to the number of patients among Korean women. With it, ultrasonographic screening test has also become very common. However, there is still controversy over the performance of this screening test. Therefore, the National Evidence-based Healthcare Collaborating Agency (NECA) organized a Round-table Conference on the issues regarding ultrasonographic screening for thyroid cancer in Korea. The objective of the conference was mainly about delivering worthwhile information reflecting social value for the current situation, which was based on evidence surrounding thyroid cancer screening that relevant experts investigated and agreed on. The significance of this Round-table Conference lies in the fact that we reviewed the current evidence, and we were able to discuss the social value and future direction for ultrasonographic screening in Korea.

사구종은 신경근동맥성 사구에서 발생하는 손톱 밑의 피하 지방층에 발생하는 드문 종양이다. 조직학적으로 고유 사구종양, 사구맥관종, 사구맥관근종으로 분류하고 있는데 이 중 사구맥관근종은 가장 드물다고 알려져 있다. 또한 다른 사구체 종양과는 다르게 사지나 손톱 밑에서 호발하지 않는다. 사구체 종양은 특징적인 임상 증상으로 일차 진단이 가능하지만 방사선학적으로는 초음파 또는 자기공명 영상이 이용되고 있다. 저자들은 수지에 발생한 재발성 손톱밑 사구맥관근종에 대한 초음파를 이용한 진단 및 수술적 치료에 대한 경험을 보고하고자 한다.

A 52-year-old female patient presented with an 8-year history of progressively intense pain, cold sensitivity, and severe tenderness to palpation of the ulnar side of the tip of her right little finger. Subsequent diagnostic evaluation with ultrasonographic imaging revealed the presence of a glomus tumor in the tender area. Glomus tumors are benign, occurring in the vascular hamartomatous tubercles of the glomus body, which is a myoarterial apparatus typically found in the reticular dermis of the skin. Distal glomus tumors are relatively uncommon, and account for approximately 1% of all hand tumors. Most of them are located in the subungual area because of its high concentration of glomus bodies. We report a case of a glomus tumor with a typical triad of symptoms, yet with a rare location : on the pulp of the ulnar aspect of the distal phalanx of the right little finger.

We report a case of neurilemmoma of deep peroneal nerve sensory branch that triggered sensory change with compression test on lower extremity. After resection of tumor, there are evoked thermal changes on pre- and post-operative infrared (IR) thermographic images. A 52-year-old female presented with low back pain, sciatica, and sensory change on the dorsal side of the right foot and big toe that has lasted for 9 months. She also presented with right tibial mass sized 1.2 cm by 1.4 cm. Ultrasonographic imaging revealed a peripheral nerve sheath tumor arising from the peroneal nerve. IR thermographic image showed hyperthermia when the neurilemoma induced sensory change with compression test on the fibular area, dorsum of foot, and big toe. After surgery, the symptoms and thermographic changes were relieved and disappeared. The clinical, surgical, radiographic, and thermographic perspectives regarding this case are discussed.

Keratocystic odontogenic tumor (KCOT) is a benign odontogenic tumor with a potentially aggressive and infiltrative behavior. KCOT is most commonly occurred in mandible and demonstrate a unilocular, round, oval, scalloped radiolucent area, while large lesions may appear multilocular. An important characteristic of KCOT is its propensity to grow in an antero-posterior direction within medullary cavity of bone causing minimal expansion. Definitive diagnosis relies on histological examination. In this report, a KCOT that had an expansion both buccal and lingual cortical bone is described including its features in computed tomography and ultrasonographic exams. The lesion was removed surgically via an intraoral approach under local anesthesia and histologically reported as a KCOT.
