A 13-year-old neutered female Maltese was referred to Veterinary Medical Teaching Hospital of Seoul National University with 8-month-history of gradually enlarging retrobulbar mass in the right eye. On the ophthalmic examinations, exophthalmos, exposure keratitis, and cataract were observed, and menace response was absent in the eye. The fellow eye was normal except for nuclear sclerosis. On the ocular ultrasonographic evaluation, a mass was identified in retrobulbar and periocular region in the right eye. Exenteration was performed in order to remove the mass. Histopathologic evaluation revealed that most part of the mass was composed of epithelial-like neoplastic cells. Invasion into adipose cells and osseous metaplasia around the mass were also confirmed. Based on the radiologic and histopathologic examination, the mass in the right eye was diagnosed as primary retrobulbar meningioma. Eleven months after the surgery, recurrence was not observed.

Background: To evaluate the clinical and functional outcomes of arthroscopic-assisted reduction and percutaneous screw fixation for glenoid fractures with scapular extension, and investigate the radiologic and clinical benefits from the results. Methods: We evaluated patients treated with arthroscopic-assisted reduction and percutaneous screw fixation for glenoid fractures with scapular extension from November 2008 to September 2015. Fractures with displacement exceeding one-fourth of the anterior-articular surface or more than one-third of the posterior-articular surface in radiographic images were treated by surgery. Clinical assessment was conducted based on range of motion, Rowe score, and Constant score of injured arm and uninjured arm at last follow-up. Results: Fifteen patients with Ideberg classification grade III, IV, and V glenoid fracture who underwent arthroscopic-assisted reduction using percutaneous screw fixation were retrospectively enrolled. There were no differences in clinical outcomes at final follow-up compared to uninjured arm. Bone union was seen in all cases within five months, and the average time to bone union was 15.2 weeks. Ankylosis in one case was observed as a postoperative complication, but the symptoms improved in response to physical therapy for six months. There was no failure of fixation and neurovascular complication. Conclusions: We identified acceptable results upon radiological and clinical assessment for the arthroscopic-assisted reduction and percutaneous fixation. For this reason, we believe the method is favorable for the treatment of Ideberg type III, IV, and V glenoid fractures. Restoration of the articular surface is considered to be more important than reduction of fractures reduction of the scapula body.

Objective: To show a decrease in tumor recurrence and improvement in quality of life in patients with recurrent cervical cancer. Method: A 58-year-old female patient diagnosed with recurrent cervical cancer in February 2021 was treated for 14 months with integrative cancer treatment (ICT) to decrease the tumor size and improve chemotherapy-induced peripheral neuropathy (CIPN) and nausea. The patient underwent chemotherapy or concomitant chemoradiation therapy (CCRT) with ICT. Radiologic outcomes were assessed by abdomen & pelvis computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography-computed tomography (PET-CT) based on the Response Evaluation Criteria in Solid Tumors (RECIST) protocol. Clinical outcomes were assessed by the National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), Eastern Cooperative Oncology Group (ECOG), and a numeric rating scale (NRS). Result: During the 14 months of treatment, the size and metabolic activity of the recurrent tumor decreased and underwent partial remission based on RECIST. The NRS scores for CIPN and nausea were improved, and the ECOG score improved from grade 2 to 1. No serious side effects of grade 3 or higher were noted on the NCI-CTCAE test. Conclusion: This case suggests that ICT may have a synergetic effect with chemotherapy or radiotherapy for recurrent cervical cancer.

Purpose: A response to conservative treatment is usually obtained in cases of ischiogluteal bursitis. However, the time required to achieve relief of symptoms can vary from days to weeks, and there is a high recurrence rate, thus invasive treatment in addition to conservative treatment can occasionally be effective. Therefore, the aim of this study was to examine surgical excision in cases of refractory ischiogluteal bursitis and to evaluate patients' progression and outcome. Materials and Methods: A review of 21 patients who underwent surgical excision for treatment of ischiogluteal bursitis between February 2009 and July 2020 was conducted. Of these patients, seven patients were male, and 14 patients were female. Injection of steroid and local anesthetic into the ischial bursa was administered at outpatient clinics in all patients, who and they were refractory to conservative treatment, including aspiration and prescription drugs. Therefore, surgery was considered necessary. Excisions were performed by two orthopedic specialists using a direct vertical incision on the ischial area. A review of each patient was performed after excision, and quantification of the outcomes recorded using clinical scoring systems was performed. Results: The results of radiologic evaluation showed that the mean lesion size was 6.2 cm×4.5 cm×3.6 cm. The average disease course after excision was 21.6 days (range, 15-48 days). Measurement of clinical scores, including the visual analog scale and Harris hip scores, was performed during periodic visits, with scores of 0.7 (range, 0-2) and 98.1 (range, 96-100) at one postoperative month, respectively. Conclusion: Surgical excision, with an expectation of favorable results, could be considered for treatment of ischiogluteal bursitis that is refractory to therapeutic injections, aspirations, and medical prescriptions, particularly in moderate-to-severe cases.

From February 1987 through July 1990, the seventeen cases of inoperable intracranial arteriovenous malformation (AVM) were treated using 6 MV linear accelerator at the Division of Therapautic Radiology, Kang Nam 51. Mary's Hospital. Of seventeen cases, fourteen were male and three were female. Ages ranged from 10 to 51 years (median age of 25 years). The main symtoms were headache, epilepsy and hemiparesis in decreasing order of frequency. The middle cerebral artery is the most common origin of the feeding vessel $(41.2\%)$. Four were treated by conventionally fractionated radiation therapy (CRT, thirteen were treated by stereotactic radiosurgery (RS). duration or follow-up in CRT and RS group were 4 to 43 months (median 33 months) and 3 to 12 months (median 13 months), respectively. When the response was assessed by radiologic follow-up study, two of four CRT group showed minimal response. Of thirteen cases of RS group, two $(15.4\%)$ showed complete response, five $(38\%)$ partial response, two $(15.4\%)$ minimal response and four $(30.7\%)$ no response by the same assessment. There was no statistical significance in terms of follow-up period (p=0.22), size of lesion (p=0.82) and treated dose (p=0.05). Further accumulation of experience is recommended with proper case selection and sufficient follow-up period.

The purpose of this study was to discuss the required items and feasibility of medical records of radiological examinations performed by radiological technologists at medical institutions. An online survey was conducted to a total of 10,000 radiation-related workers, of which 1,026 (10.3%) responded. As a research method, self-made questionnaires were used. The online survey was conducted from September 10 to September 20, 2021 for the survey period. For response data, a Chi-square test was performed according to demographic characteristics using SPSS 27.0 version (IBM Inc., Chicago, Ill, USA), and it was judged to be significant when the P value was less than 0.05. The reliability of the questionnaire response was found to be Chronbach α=0.933. More than 90% of the medical records related to radiological examinations are necessary, and they answered that a curriculum, remuneration curriculum, and legal system for medical records should be prepared. More than 90% of the respondents agreed with the proposal of the Radiological Technologist Independent Act for legal preparation, and most of the information required for medical records is currently recorded in DICOM images. According to the demographic characteristics, the medical record requirement for radiological examination, curriculum, continuing education, and legislation were found to be higher with higher education and higher with longer working experience. In addition, most of the radiology departments showed a high demand for medical records, so most of them responded positively to the medical records requirements for radiological examinations. This study analyzed the medical record requirements for radiological examinations, and as shown in the results, medical record requirements for radiological examinations was found that most radiological technologists felt need for the new law and supported it. In addition, if the information recorded in the DICOM image is used, it is considered that medical records could be easily prepared without additional work by the radiological technologists.

The purpose of this study is to check the extent to which "instruction of physician or dentist" defined in the Medical Service Technologists, etc. Act is applied in relation to radiography examination procedures for radiological technologists. In addition, it is intended to present basic data on the requirement to revise the Medical Service Technologists, etc. Act in the radiological technologist's duty area and scope of work, The subjects of this study were radiological technologists with license, and the response data were collected after sending the questionnaire link written on the online questionnaire form. The final number of respondents were 1,018, and the response rate was 6.8%. Most of the negative responses were "I have never received 'instruction' for radiologic examination by a physician or dentist, including a radiologist in a medical environment." There were a high perception that "the professionalism in radiation examination on radiological technologists are higher than that of a physician or dentist." They answered that the current continuing education has a great impact on maintaining and continuing professionalism and learning new knowledge in the radiology field. In addition, the radiological technologists provide a very high level of education in areas related to radiography procedure ethics such as patient care, patient safety, and patient privacy protection, as well as specialized fields such as radiation-related examination methods, radiography examination dose, and patient exposure dose. Radiological technologists replied that they were receiving it consistently. In conclusion, in the current medical environment, the 'instruction' of a physician or dentist cannot be seen as being realistically performed. The phrase 'instruction' of a physician or dentist as defined in the Medical Service Technologists, etc. Act is considered inappropriate in respect of the fact that the state recognizes the qualifications of the medical service technologist through a license. It is thought that revision to a new term suitable for the current medical environment is necessary.
