Lipoma arborescens or synovial lipomatosis is a rare disorder that is characterized by mature fat infiltration of the hypertrophic synovial villi, most frequently affecting the supra-patellar pouch of the knee. This paper presents a case of lipoma arborescens of the ankle joint bilaterally in an adult patient with involvement of both the intra-articular synovium and the synovial sheath of the tendons around the ankle.

A 17-year-old male patient of aortic stenoinsufficiency with a small aortic annulus underwent aortic valve replacement[St. Jude Medical valve 21mm] with Rittenhouse-Man-ouguian procedure[patch enlargement of the area of the noncoronary sinus and anterior mitral leaflet] The used patch was made from tubular dacron graft[the longitudinal length was 35mm, the width 20mm]. The length of incision into anterior mitral leaflet was 10mm and the aortic annulus was enlarged in 10mm, The patient was evaluated with two-dimensional echocardiography at 4 month after operation and the result was excellent.

Tuberculous pericarditis is an extrapulmonary manifestation of tuberculosis that is most commonly associated with pericardial thickening, effusion, and calcification. We present a case of tuberculous pericarditis mimicking a malignant pericardial tumor in a 77-year-old male. CT revealed an irregular and nodular pericardial thickening. MRI revealed high signal intensity on T1-weighted fat-suppressed images and peripheral rim enhancement after gadolinium administration. MRI can be helpful in determining the differential diagnoses in cases of tuberculous pericarditis with nonspecific imaging findings.

Objectives : The purpose of this study was to investigate the association between the insulin resistance and depressive mood, suicidal ideation, psychological stress, and quality of life in general Korean population. Methods : We selected 3,613 subjects from the third year's data of 6th Korean National Health and Nutritional Examination Survey. Insulin resistance was evaluated with Homeostatic Model Assessment of Insulin Resistance. Questionnaires on depressive mood, suicidal ideation and psychological stress were conducted. The quality of life was assessed with the EuroQol-5 dimension index. We used correlation and regression analysis for analysis. Results : The risk of depressive mood and suicidal ideation was significantly higher in the insulin resistance group than in the control group. The risk of psychological stress was significantly higher in the male group with insulin resistance. The EuroQol-5 dimension index showed a negative correlation with insulin resistance. After adjusting for age, sex and body mass index, increased risk of suicidal ideation was identified only. Conclusions : We confirmed that insulin resistance is associated to mental health problems related with depression in Korean adults.

Herein, we report a case of synchronous bilateral triple negative invasive ductal breast carcinoma in a patient with discrepant pathologic response to neoadjuvant chemotherapy. Right and left breast cancer stages at the initial diagnosis were T1cN0M0 and T4dN3aM0, respectively. The patient was identified as a BRCA1 mutation carrier and treated with four cycles of adriamycin and cyclophosphamide, followed by four cycles of docetaxel. Bilateral breast cancer stages decreased with the first regimen. However, the bilateral breast cancers showed discrepant responses to chemotherapy with docetaxel. The right breast cancer showed a continuous tumor volume reduction while the left breast cancer showed marked progression. Finally, the tumor size was 0.3 cm and 12 cm in the right and left mastectomy specimens, respectively. As bilateral breast cancers of the same subtype may show discrepant responses to neoadjuvant chemotherapy, close monitoring and follow-up imaging are required to avoid delayed surgery.

Rosai-Dorfman Disease (RDD) is a rare lymphoproliferative disease, and the occurrence of isolated intracranial RDD is extremely rare. Most cases of intracranial RDDs present as dural masses showing homogenous enhancement on MRI, which makes it difficult to differentiate these masses from meningiomas before surgery unless massive cervical lymphadenopathy is observed. We herein report a rare case of isolated intracranial RDD in a 65-year-old male. Brain MRI revealed a well-defined enhancing mass-like lesion involving the right frontal convexity and subtle diffusion restriction. However, only a subtle blush was observed on the preoperative cerebral angiogram. Although instances of isolated intracranial RDD are rare, it should be considered as a potential differential diagnosis when a dural mass with hypovascularity is visualized on the cerebral angiogram.

Gerstmann-Sträussler-Scheinker (GSS) disease is a rare hereditary prion disease which is clinically characterized by a progressive cerebellar ataxia followed by cognitive impairment. We report a rare case of GSS disease in a 39-year-old male patient who complained of a progressive gait disturbance followed by dysarthria with cognitive impairment, after five months from the onset of initial symptom. His brain MRI scan revealed multifocal symmetric diffusion restricted lesions with T2/FLAIR hyperintensities in bilateral cerebral cortices, basal ganglia, and thalami. His family members also manifested similar symptoms in their 40-50s, suggesting the possibility of a genetic disease. Finally, he was genetically diagnosed with GSS disease by real-time quaking-induced conversion and prion protein (PRNP) gene sequencing test.

Inflammatory pseudotumors (IPTs) are uncommon, mass-forming lesions, predominantly involving the lung and orbit. Although the incidence of IPTs is rare in the abdomen and pelvis, they can be encountered as enhancing, soft-tissue lesions, mimicking malignancy or fibrosclerosing disease. Generally, they exhibit a wide range of nonspecific imaging features in various organs. Preoperative imaging diagnosis of IPTs in appropriate clinical settings may help determine proper patient management. In this article, we review radiologic findings of IPTs in the abdominopelvic cavity, including the liver, spleen, kidney, gastrointestinal tract, mesentery, pelvis, and retroperitoneum.

Purpose: The purposes of this study were to determine the changes in the pattern of patients who were transferred to the emergency room through inter-hospital private institutions and to determine how long transport takes following the COVID-19 outbreak. Methods: This retrospective observational study analyzed the emergency medical services reports of private institutions following the COVID-19 outbreak in South Korea. The study was conducted in Busan between January 19, 2019 and January 18, 2020, and between January 19, 2020 and January 18, 2021. Results: Upon comparing the patient transport times during the "Pre-COVID-19 period" and "COVID-19 period," a significant delay was noticed in the preparation for transfer of patients during the "COVID-19 period" (p<.05). There were significantly more patients with respiratory infections and patients who complained of general symptoms during the "COVID-19 period." Moreover, there was a higher frequency of patients who were transferred to a 'Level I' emergency room during the "COVID-19 period" compared to during the "Pre-COVID-19 period" (p<.05). Conclusion: Following the COVID-19 outbreak, there is a delay in patient transport to the emergency room through private institution inter-hospital transport and an increase in the number of patients complaining of respiratory infection symptoms. Thus, emergency medical services need additional administrative and economic support to transport infected patients.

Columnar cell variant of papillary thyroid carcinoma (CCV-PTC) is a rare variant representing 0.15-0.2% of all PTCs. The CCV is aggressive, due to its rapid growth, high local recurrence rate, and frequent lung, brain and bone metastasis. Aggressive surgical and medical management are recommended for these neoplasias. The authors experienced a case of CCV-PTC in a 45-year-old man. We performed total thyroidectomy with neck dissection. The patient received radiation and radioactive iodine therapy. There were no recurrences or complications in the following 24 months after the operation. The patient will closely undergo continuous follow up. We present the clinical characteristics, pathology, treatment, and prognosis of the tumor with a review of the literature.
