Is multidetector CT-scan able to detect T3a renal tumor before surgery?
Conclusion: MDCT provides good results in detecting sinus fat, venous invasion and kidney-confined tumors, but evaluation of perinephric fat remains a difficult task, leading to reduced accuracy in T3a staging. PMID: 31607203 [PubMed - as supplied by publisher]
CONCLUSIONWe described the first case of renal pericytic tumor, addressing uncertain malignant potential, in a Korean male, which would be a distinct mesenchymal neoplasm differentiating from other groups of perivascular tumor families based on histological and immunohistochemical features.
ConclusionEntropy, which is a quantitative measure of heterogeneity, is increased in clear cell renal cancers. High entropy is also associated with high-grade renal cancers. This parameter may be considered as a supplementary marker when determining aggressiveness of therapy.Key points• CT texture analysis is easy to perform on contrast-enhanced CT.• CT texture analysis may help to separate different types of renal cancers.• CT texture analysis may enhance individualized treatment of renal cancers.
ConclusionsAccurate preoperative differential diagnosis of chRCC and RO can be facilitated by a combination of CT-enhanced quantitative features and machine learning.
ConclusionWe highlight here the challenge to make the difference between a primary gallbladder carcinoma and metastasis from RCC. Diagnosis is made on pathological examination and immunochemistry.
Conclusions: In this sample of surgically resected tumors, CEUS was effective in characterizing renal lesions as solid neoplasms or complex cystic lesions suspicious for neoplasm-findings which merit further investigation. PMID: 31549563 [PubMed - as supplied by publisher]
Conclusions68Ga-PSMA PET/CT directly changed management in 42.1% of cases. Strongest detection rates occurred in those patients with clear cell RCC. The results of this study suggest there may be merit in the use of the modality in the staging of RCC. Further analysis, both with respect to histological confirmation, efficacy and cost-benefit, is required to determine whether there is a role for routine68Ga-PSMA PET/CT imaging.
Rationale: Ossifying fibroma is benign fibro-osseous neoplasm. The authors report a case of ossifying fibroma in the mandibular angle suspected as metastasis of clear cell renal cell carcinoma. Patient concerns: A 74-year-old man presented to the primary hospital complaining of frequent urination. A tumor in the left kidney was detected via an abdominal computed tomography scan. The patient then visited the Department of Urology at our hospital. Diagnoses: According to whole-body imaging examinations, the patient was suspected of having renal cancer with mandibular metastasis. Also, a cystic lesion of the maxilla w...
ConclusionsPET/CT, as a non-invasive method, can be preferred as the first choice in the detection of primary tumor in patients with BMUO.ResumenObjetivoEste trabajo analiza el papel de la PET/TC con 18F-FDG en la detección del tumor primario en pacientes con metástasis óseas de origen desconocido (MOOD).Material y MétodosEste estudio retrospectivo consideró al análisis histopatológico o el seguimiento clínico como datos de referencia en el diagnóstico de tumores primarios y estos resultados fueron comparados con los resultados de la PET/TC.ResultadosSe incluye...
Abstract We investigated the effectiveness of 11C-choline-positron emission tomography/computed tomography (PET/CT) for evaluating treatment response in patients with prostate cancer or renal cell carcinoma. We performed 34 11C-choline PET/CT scans before/after a combined total of 17 courses of treatment in 6 patients with prostate cancer and 2 with renal cell carcinoma. The 17 treatments including hormonal therapy, radiotherapy, chemotherapy, radium-223, molecular target therapy, radiofrequency ablation, transcatheter arterial embolization, and cancer immunotherapy yielded 1 (5.9%) complete metabolic response (CM...
CONCLUSION: RPN with a standard laparoscopic ultrasound probe is safe, effective and feasible in treating endophytic renal tumor. Our original approach for separating renal mass can avoid some problems caused by the standard laparoscopic ultrasound probe. PMID: 31350090 [PubMed - as supplied by publisher]
