Introduction: Percutaneous renal mass biopsy has evolved over the last decade with improvements on previous pitfalls including low tissue yield, high non-diagnostic rates, and complications. As understanding of tumor biology and natural history of renal cortical neoplasms has improved, percutaneous renal mass biopsy is poised to have an expanding role in an area characterized by individualized management and refined risk stratification.
Areas covered: This review summarizes the evolution of renal mass biopsy to its current state with respect to outcomes, indications, and clinical guidelines.
Expert opinion: With improved understanding of differential biological potential of renal cortical neoplasms combined with technical improvements in diagnostic yield and accuracy, utilization of renal mass biopsy is becoming an important adjunct to patient care in a broad range of clinical scenarios, including active surveillance, thermal ablation, and use of primary systemic therapy in localized and advanced settings. 相似文献

We present an unusual case of tophaceous pseudogout in the atlantoaxial joint with progressive cervical cord compression
symptoms and lack of additional clinical manifestations of CPPD crystal deposition disease. This represents only the fourth
reported case in the medical literature. 相似文献

Background
We analyzed oncological outcomes in patients who underwent percutaneous renal cryoablation (PRC) with documented renal cell carcinoma (RCC) by perioperative biopsy.Methods
Multicenter retrospective analysis of 153 patients [median follow-up 48 months] who underwent PRC from 09/2005 to 08/2014 was performed. We divided the cohort into patients who developed recurrence versus no recurrence. Kaplan–Meier analyses examined recurrence-free survival (RFS) according to grade and histology. Multivariable analysis (MVA) was performed to identify factors associated with tumor recurrence.Results
One hundred and fifty-three patients were analyzed [18 patients (11.8 %) with recurrence and 135 (88.2 %) patients without recurrence]. There were no differences between the groups with respect to demographics, RENAL score, and number of probes utilized. Recurrence group had larger tumor size (3.1 vs. 2.4 cm; p = 0.011), upper pole tumor location (p = 0.016), and greater proportions of high-grade tumor (33 vs. 0.7 %; p < 0.001) and clear cell histology (77.8 vs. 45.9 %; p = 0.011). Four-year RFS was 100 versus 80 % for grade 1 versus grade 2/3 tumors (p = 0.0002), and 97 versus 88 % for other RCC versus clear cell RCC (p = 0.07). MVA demonstrated tumor size >3 cm (OR 2.46; p = 0.019), clear cell histology (OR 2.12; p = 0.027), and high tumor grade (OR 2.33, p < 0.001) as independent risk factors associated with tumor recurrence.Conclusions
Association of higher grade and clear cell histology with recurrence and progression suggests need for increased emphasis on preoperative risk stratification by biopsy, with grade 1 and non-clear cell RCC being associated with improved treatment success than higher grade and clear cell RCC.4.

A patient with an enlarging thoracic aortic aneurysm (TAA) after endovascular repair showed a persistent endoleak on follow-up imaging at three and six months. He subsequently underwent angiography and transcatheter embolization of a right thyrocervical trunk bronchial collateral. Examination of potential anomalous or collateral thoracic pathways is mandatory when considering treatment of a Type II endoleak following endovascular TAA repair. 相似文献

Purpose: To describe our experience with ultrasound (US)-guided percutaneous liver biopsies using the INRAD 18G Express core needle
biopsy system.
Methods: One hundred and fifty-four consecutive percutaneous core liver biopsy procedures were performed in 153 men in a single institution
over 37 months. The medical charts, pathology reports, and radiology files were retrospectively reviewed. The number of needle
passes, type of guidance, change in hematocrit level, and adequacy of specimens for histologic analysis were evaluated.
Results: All biopsies were performed for histologic staging of chronic liver diseases. The majority of patients had hepatitis C (134/153,
90.2%). All patients were discharged to home after 4 hr of postprocedural observation. In 145 of 154 (94%) biopsies, a single
needle pass was sufficient for diagnosis. US guidance was utilized in all but one of the procedures (153/154, 99.4%). The
mean hematocrit decrease was 1.2% (44.1–42.9%). Pain requiring narcotic analgesia, the most frequent complication, occurred
in 28 of 154 procedures (18.2%). No major complications occurred. The specimens were diagnostic in 152 of 154 procedures (98.7%).
Conclusions: Single-pass percutaneous US-guided liver biopsy with the INRAD 18G Express core needle biopsy system is safe and provides
definitive pathologic diagnosis of chronic liver disease. It can be performed on an outpatient basis. Routine post-biopsy
monitoring of hematocrit level in stable, asymptomatic patients is probably not warranted. 相似文献

PURPOSE: Determine the feasibility of using three-dimensional ultrasonography (3D US) to assist in planning and performing endocavitary drainage of deep pelvic fluid collections. MATERIALS AND METHODS: Retrospective review of images and medical records of 16 patients in whom endocavitary 3D US was used during transvaginal or transrectal drainage of 17 deep fluid collections. 3D US was assessed regarding its ability to display the relevant structures, whether new information was provided compared with pelvic computed tomography (CT) and conventional two-dimensional US (2D US) displays, and whether this information altered drainage techniques. RESULTS: Targeted fluid collections were visualized in all patients. 3D US added information in 11 of 16 patients (69%) that, in turn, resulted in adjustment of interventional technique in eight of 16 patients (50%). Specific features of 3D US that provided new information included the simultaneous display of three orthogonal US images, display of reconstructed US image plane orientations not possible with 2D US, and the ability to interactively scroll images through complex structures to assess for communication between the loculations. An attached needle guide was used in 15 of 16 patients to improve the precision of needle placement. CONCLUSION: Endocavitary 3D US is feasible for assistance in transvaginal and transrectal drainage procedures, usually adds new information, frequently alters interventional technique, and permits precise access needle placement. 相似文献

We present a case of sarcoidosis with soft tissue masses and associated phalangeal erosive changes. Sarcoidosis of the musculoskeletal
system presenting as a soft tissue mass has been described previously but is rare. To our knowledge, the combination of soft
tissue masses and phalangeal erosions has never been described. 相似文献
