The widespread use of diagnostic radiography, especially using magnetic resonance imaging, has helped to increase the diagnosis of paralabral cysts in patients with chronic shoulder pain. These paralabral cysts are frequent in the anterior, the superior, and the posterior compartment of the shoulder joint but are rare in the inferior compartment. Paralabral cysts in the shoulder appear particularly in men in their third and fourth decades but rarely in elderly patients. We report a case of an inferior paralabral cyst in an elderly patient whom we treated through arthroscopic decompression.

Journal of Urologic Oncology 2024;22(1):42-51
Purpose:
Renal cell carcinoma (RCC) is a relatively common malignancy of the urinary tract. Over the past few decades, methodologies for diagnosing and managing patients with RCC have shown various developmental stages. This study was designed to provide insights into RCC research trends over that period.
Materials and Methods:
To understand RCC research trends over the past 30 years, we conducted a bibliometric analysis, an appropriate method for evaluating scholarly output. Data were acquired by searching the Web of Science for articles published between 1991 and 2020. Bibliometric analysis and VOSviewer were used to visualize and statistically analyze the research trends.
Results:
A total of 18,172 articles were identified. The most productive country was the United States (n=4,461, 26.5%), followed by China (n=3,503, 19.9%), and Japan (n=1,950, 11.9%). During keyword analysis, 3 clusters were identified, relating to gene expression, surgical outcomes, and immunotherapy. Over the last 10 years, research has mostly focused on emerging immunotherapy-related drugs.
Conclusions
Our bibliometric analysis has explained the characteristics of RCC research trends over the past 30 years.

PURPOSE: To present initial and follow-up HRCT findings of lymphangitic carcinomatosis of the lung. MATERIALS AND METHODS: Both initial and follow-up HRCT scans were obtained in 18 patients with lymphangitic carcinomatosis of the lung. After dividing the patients into two groups (with anticancer chemotherapy (n=12) and without chemotherapy (n=6), changes of pulmonary parenchymal abnormalities (percentile increase or decrease in the extent of each pattern) were assessed and compared on initial and follow-up HRCTs. RESULTS: Findings on initial CT were interlobular septal thickening (n=18) (smooth in 15 and mixed smooth and nodular in three), thickening of bronchovascular bundles (n=17), areas of ground-glass opacity (n=15), polygonal lines (n=15), and nodules (n=10). With chemotherapy, the finding of polygonal lines decreased by 20/3%, while findings of ground-glass opacity, bronchovascular bundle thickening, septal thickening, and nodules remained stable. Without chemotherapy, all CT patterns of abnormalities except nodules increased by 45-88%. In three patients who did not undergo chemotherapy, smooth interlobular septal thickening changed to nodular thickening. CONCLUSION: Lymphangitic carcinomatosis of the lung manifests initially as smooth thickening of the interlobular septae, bronchovascular bundle thickening,areas of ground-glass opacity, and polygonal lines, as seen on HRCT. Without chemotherapy, the extent of CT findings increases and there is a tendency for smooth septal thickening to change to nodular thickening. Chemotherapy induces improvement or cessation of the progression of CT findings.

Seminal vesicle cysts combined with ipsilateral renal agenesis represent a rare urologic anomaly. This urogenital malformation is explained as a developmental failure in the same mesodermal region. We report a case of seminal vesicle cyst, ipsilateral dilated ureter and renal agenesis which was treated by surgical excision. And we searched the literature to review the clinical presentation, diagnosis and treatment options of this anomaly.

PURPOSE: To analyze the risk factors for postoperative lymphocele, for predicting and preventing complications. METHODS: We evaluated 92 kidney transplant recipients with multidetector CT (MDCT) at 1-month posttransplantation. From admission and 1-month postoperative records, data including diabetes, dialysis type, immunosuppressant use, steroid pulse therapy, and transplantation side were collected. Lymphocele volume was measured with 3-dimensional reconstructed, nonenhanced MDCT at one month postoperatively. The correlations between risk factors and lymphocele volume and between risk factors and symptomatic lymphocele (SyL) were analyzed. The cutoff was calculated by using the receiver operating characteristic (ROC) curve for SyL volume. RESULTS: Among 92 recipients, the mean volume was 44.53 ± 176.43 cm³ and 12 had SyL. Univariable analysis between risk factors and lymphocele volume indicated that donor age, retransplantation, and inferiorly located lymphocele were statistically significant. The ROC curve for SyL showed that 33.20 cm³ was the cutoff, with 83.3% sensitivity and 93.7% specificity. On univariable analysis between risk factors and SyL, steroid pulse, inferiorly located lymphocele, and >33.20 cm³ were statistically significant. Multivariable analysis indicated that steroid pulse, >33.20 cm³, and serum creatinine level at one month were significant factors. CONCLUSION: Risk factors including donor age, retransplantation, steroid pulse therapy, and inferiorly located lymphocele are important predictors of large lymphoceles or SyL. In high-risk recipients, careful monitoring of renal function and early image surveillance such as CT or ultrasound are recommended. If the asymptomatic lymphocele is >33.20 cm³ or located inferiorly, early interventions can be considered while carefully observing the changes in symptoms.

PURPOSE: To evaluate a recently developed technique to place a medium-duration(weeks to months) central venous access. MATERIALS AND METHODS: Within three-year period, 635 patients were referred to interventional radiology suite for placement of peripherally inserted central catheter(PlCC). Contrast medium was injected into the peripheral intravenous line and a puncture was made into the opacified vein near the junction of the middle and upper thirds of the upper arm, either the brachial or basilic vein under fluoroscopic guidance. A 5.5-French peel-away sheath was inserted into the vein and a 5- French silicone catheter was introduced with its distal tip to the junction of the right atrium and superior vena cava. RESULTS: Catheter placement was successful in all patients unless there was a central venous obstruction. Catheters were maintained from 2 days to 5 months with a mean of 3 weeks. Complications included infection requiring removal of the PICC in 16 patients(2.5%), acute thrombosis of the subclavian vein in 3(0.5%). Occluded catheters in 4 patients were easily cleared with urokinase in place. CONCLUSION: The PICC system is an excellent option for medium-duration cen- tral venous access. Patients were able to carry on normal activities with the catheters in place.
