변장원,박영진,남상훈,김대구,최종민,마기중,권용성 대한시과학회 2000 대한시과학회지 Vol.2 No.1

Orbscan Topography System 및 A - scan Ultrasonography로 전 방깊 이 훌 측정 하 여 두 기 기 의 신 뢰 도를 평 가하고, A - scan Ultrasonography률 gold standard로 간주 하여 Orbscan Topography System으로 측정한 전방깊이 값의 정확도를 분석하였다. 20안올 대 상으로 Orbscan Topography System 및 A - scan Ultrasonography롤 이 용 하여 측정한 test 와 retest 차이에 대한 평균값은 각각 0.030 :t 0.150 mm와 0.016:t 0.065mm 였다. 또한 54안을 대상으로 Orbscan Topography System과 A - scan Ultrasonography로 측정한 전방깊이 값의 평균은 각각 3.200:t 0.302 mm와 2.999:t 0.239mm로, Orbscan Topography System 측정 값이 더 높았으며 (t = 10.α)3, p<O.αX)1), 두 기기의 측정값 사이에 높은 상관관계가 있었다 (r = 0.824, p<O.OOül). Orbscan Topography System 측정값을 A - scan Ultrasonography 측정값과 직접 비교하기 위해서는 환산공식이 필요하다. The study assessed repeatability of the anterior charnber depth estimates provided by the Orbscan Topography System. and an A - scan U1trasonoragpy, and assessed comparability of the Orbscan Topography Systme and A - scan Ultra -sonography as gold standard. In the 20 eyes, mean of the differences of Test and Retest in anterior charnber depth measured by Orbscan Topography System and A - scan Ultrasonography were 0.03O:t 0.150 mm and 0.016 mm, respectively. In 54 eyes, mean of ACD measured by Orbscan Topography System and A - scan Ultrasonography were 3.2oo:t 0.302 mm and 2.999:t 0.239 mm, respectively. Mean ACD values measured by Orbscan Topography was more deeper than that of measured by A - scan Ultrasonography(t=10.oo3, p<O.α)()1) , and the correlation coefficient between Orbscan and ultrasonography was 0.824(p <0.0001). Therefore, there was required conversion factor when ACD values measured by Orbscan Topography System was directly compared to that of measured by A - scan Ultrasonography.

경미한 둔상에 의하여 야기되는 늑연골 골절 진단에 있어서 흉벽 초음파 검사의 임상적 유용성

이우성,김요한,지현근,황재준,이송암,정호성,신현준,최영칠 대한흉부외과학회 2009 Journal of Chest Surgery (J Chest Surg) Vol.42 No.4

Background: Rib fractures are the most common injuries that are caused by blunt chest trauma. However, fractures of the costal cartilage generally go unnoticed on chest X-rays unless they involve a calcified cartilage. For this reason, the sensitivity of conventional radiography for detecting rib fractures is low, and especially those involving the cartilaginous part of the rib. Thus, we have evaluated the usefulness of ultrasonography for detecting fractures of the costal cartilage that were overlooked on the conventional radiographs of patients who suffered minor blunt chest traumas. Material and Method: A total of 45 patients who suffered minor blunt chest trauma and who had no evidence of rib fractures or other major fractures on conventional radiographs were admitted for ultrasonography between April 2008 and March 2009. There were 24 women and 21 men, and the mean age of the patients was 50.4±15.91 years (range: 17∼76 years). They were examined for the detection of fractures of the costal cartilage by performing ultrasonography with a 7.5-MHz linear transducer. Result: A total of 30 patients (67%) had fractures of the costal cartilage, whereas 15 patients (33%) had no evidence of chondral rib fractures. The mean number of fracture sites of the fractured costal cartilage was 1.6±0.81 (range: 1∼4 sites) in 30 patients. Periosteal hematoma was the most common finding associated with fractures of the costal cartilage (n=7, 17%), followed by sternum fracture (n=5, 12%). However, periosteal hematoma was noticed in 1 patient (2%) who was without fracture of the costal cartilage, and sternum fracture was noticed in 1 patient (2%) who was without fractures of the costal cartilage. Conclusion: The results of this study suggest that ultrasonography may be a useful imaging modality for detecting fractures of the costal cartilage that are overlooked on the conventional radiographs of patients who suffer minor blunt chest trauma. 배경: 늑골 골절은 흉부 외상 중에 둔상으로 인한 손상 중 가장 흔한 질환이다. 하지만 늑연골 골절은 연골 부위의 석회화가 동반되지 않는 한 고전적인 흉부 방사선 검사에서 잘 관찰되지 않으며, 이러한 이유로 고전적인 흉부 방사선 검사로는 늑연골 골절의 진단에 한계가 있다. 이에 저자들은 고전적인 흉부 방사선 검사에서 간과 되었던 늑연골 늑골 골절의 진단을 위하여 경미한 흉부 둔상 환자에게 흉벽 초음파 검사를 시행하였다. 대상 및 방법: 2008년 4월부터 2009년 3월까지 본원을 내원한 환자를 대상으로 하였고, 고전적 방사선 검사에서 이상 소견이 없었으며 중증 손상을 의심할 만한 병변이 없는 총 45명의 환자를 대상으로 하였다. 이들 중 여성은 24명, 남성은 21명이었으며, 평균 연령은 50.4±15.91세(17∼76)였다. 상기 대상자 들은 7.5-MHz 직선 탐촉자를 지닌 초음파 기기를 이용하여 흉벽 초음파 검사를 시행하였다. 결과: 대상이 된 45명의 환자들 중 30예(67%)에서 늑연골 골절을 관찰할 수 있었고, 15예(33%)에서는 특별한 이상 소견이 관찰되지 않았다. 골절을 지닌 30명의 평균적인 골절 개수는 1.6±0.81 부위(1∼4)였다. 늑연골 골절의 가장 흔한 동반 소견은 골막 주위 혈종으로 7예(17%)에서는 골절 소견과 동반되어 관찰되었고 1예(2%)에서는 골절 소견 없이 관찰되었다. 두 번째 흔한 동반 소견은 흉골 골절이었고, 5예(12%)에서는 연골 부위 늑골 골절과 동반되어 관찰되었고, 1예(2%)에서는 흉골 골절만 관찰되었다. 결론: 흉벽 초음파 검사는 경미한 흉부 외상 환자에게서 간과되었던 늑연골 골절의 진단에 유용한 방법으로 사료된다.

Spinal Cord Ependymoma Associated with Neurofibromatosis 1 : Case Report and Review of the Literature

Cheng, Hongwei,Shan, Ming,Feng, Chunguo,Wang, Xiaojie The Korean Neurosurgical Society 2014 Journal of Korean neurosurgical society Vol.55 No.1

Patients with neurofibromatosis 1 (NF1) are predisposed to develop central nervous system tumors, due to the loss of neurofibromin, an inactivator of proto-oncogene Ras. However, to our knowledge, only three cases of ependymomas with NF1 have been reported in the literature. The authors present a case of NF1 patient with a spinal cord ependymoma. She was referred for about half a year history of increasing numbness that progressed from her fingers to her entire body above the bellybutton. Magnetic resonance imaging revealed a relative-demarcated, heterogeneously enhanced mass lesion accompanied by perifocal edema in C5-7 level, a left-sided T11 spinous process heterogeneously enhanced mass in soft tissue, intervertebral disk hernia in L2-5 level, and widespread punctum enhancing lesion in her scalp and in T11-L5 level. The patient underwent C5-7 laminectomies and total excision of the tumor under operative microscope, and intraoperative ultrasonography and physiological monitoring were used during the surgery. Histopathologically, her tumor was found to be a ependymoma without malignant features (grade II in the World Health Organization classification). Therefore, no adjuvant therapy was applied. Following the operation, the patient showed an uneventful clinical recovery with no evidence of tumor recurrence after one year of follow-up.

Purpose: In the treatment of trigger thumb, inadequate or excessive release of the flexor pulley can lead to secondary complications such as bowstringing. However, few studies detailed bowstringing after surgical release of the A1 pulley for trigger thumb and its influence on hand function.The purpose of this study was to determine the extent to which the release of the A1 pulley causes bowstringing in the treatment of trigger thumb, and how the percutaneous technique is beneficial to bowstringing and clinical function over open technique. Methods: The author prospectively reviewed 31 patients with resistant trigger thumb who were randomized to undergo either percutaneous release (17 patients) or open release (14 patients) of the A1 pulley. We quantified bowstringing of the thumb using ultrasonography at 12 and 24 weeks after surgery. Clinical outcomes were analyzed to correlate with the ultrasonographic measurements. Results: Each cohort showed a significant improvement in all clinical outcomes (p<0.05), with no difference between the groups at each follow-up (p>0.05). The bowstringing was greater increased at 12 weeks after surgery in both groups compared to before surgery (5.71±1.04 mm vs. 5.20±0.79 mm, p=0.039). However, the difference of those values was not significant at 24 weeks’ follow-up (5.02±0.71 mm vs. 4.86±0.33 mm, p=0.671) There was no significant correlation between the bowstringing and any clinical outcome measures (p>0.271). Conclusion: Open A1 pulley release caused greater bowstringing than percutaneous technique at initial after surgery. However, bowstringing did not affect clinical hand function in patients treated with either percutaneous or open technique.

조수진,이은일,백만종,오삼세,나찬영 대한흉부외과학회 2003 Journal of Chest Surgery (J Chest Surg) Vol.36 No.5

배경: 경두개 초음파 검사에 의한 미세색전의 진단은 향후 뇌색전증의 위험이 높은 환자의 선별에 큰 도움이 되리라 기대된다. 우리는 전향적으로 심장 판막 수술 전과 후의 미세색전의 양성률과 빈도를 검사하였다. 대상 및 방법: 심장 판막 질환이 있는 50명의 환자를 대상으로 본 연구는 진행되었다. 뇌경색의 병력이 있거나, 과거에 인공 기계 심장 판막 수술을 받은 환자는 본 연구에서 제외하였다. 경두개 초음파 검사는 중대뇌동맥에서 1시간 동안 미세색전을 감시하였고, 수술 전과 수술 후 2차례 검사하였다. 결과: 기계 심장 판막 수술은 28명, 조직 판막 수술은 10명, 승모판막 성형술은 12명에서 시행되었다. 미세색전의 양성률은 수술 전(8%)에 비하여 수술 후(50%)에 의미 있게 증가하였으며(p=0.00), 미세색전은 항응고제 강도, 심장 부정맥, 환자의 연령, 고혈압의 병력과 관련성이 없었다. 기계 심장 판막 이식수술 후 미세색전의 양성률(71.4%)은 조직 판막 이식수술(10%)이나 승모판막 성형술(33.3%)에 비하여 의미 있게 높았다(p=0.002). 결론: 미세색전은 심장 판막 수술 후 의미 있게 증가하며 이러한 변화는 인공 기계 심장 판막 수술 후 색전증의 위험과 관련되어 있다고 추정된다.

Calcified Thyroid Nodules: Review of the Significance of Peripheral Calcifications

김아영,박성빈,이용석,최희석,김경아,곽범석,황재철 대한초음파의학회 2009 ULTRASONOGRAPHY Vol.28 No.2

Thyroid calcification may occur in both benign and malignant thyroid disease, but previous literature reports have indicated that calcification is more common in malignant lesions than it is in benign ones. Various patterns of calcification are seen, including microcalcification, coarse dense macrocalcification, and peripheral calcification. Microcalcification and coarse dense macrocalcification are two of the most specific features of thyroid malignancy. However, to date, the clinical significance of peripheral calcification remains unclear and therefore controversial. In this pictorial review, we describe the ultrasonographic features of calcified thyroid nodules and seek to delineate the spectrum and determine the clinical significance of peripheral calcification by correlating it with pathologic results. A broad spectrum of benign to malignant tumors is associated with peripheral calcification. Peripheral calcification in a thyroid nodule should be considered to indicate an indeterminate lesion, and ultrasonography-guided FNAB or core biopsy should be performed in order to exclude malignancy.

우상화,정현경,김우경 대한영상의학회 2021 대한영상의학회지 Vol.82 No.2

Neurofibromatosis type 1 (NF1) is a rare neuroectodermal disease that is associated with an increased risk of malignancy. Here, we report a rare case of bilateral breast cancer in a 49-yearold woman with NF1 that presented as a microlobulated oval hypoechoic mass and a complex cystic solid mass on sonography. She underwent bilateral mastectomy. The masses were diagnosed as invasive ductal carcinoma, ductal carcinoma in situ, and a malignant peripheral nerve sheath tumor. We describe the imaging findings, including ultrasonography, CT, and 18F-fluorodeoxyglucose PET.
