Purpose: Percutaneous transcatheter embolization is currently the preferred treatment for ruptured or enlarging renal angiomyolipoma (AML), although the optimum choice of embolic material has not yet been established. We present mid- to long-term outcomes following embolization of AMLs with Onyx.
Materials And Methods: Ten AMLs in seven patients (including two with tuberous sclerosis) were embolized with Onyx. Patients were followed-up clinically, with tumour size and renal function measured pre- and post-procedure.
Results: Mean pre-treatment AML size was 63.4 mm (range 42-100). Mean clinical follow-up was 431.4 days (range 153-986) and imaging follow-up 284.2 days (range 30-741). There was no haemorrhage from treated lesions within the follow-up period. Of patients who had cross-sectional imaging pre- and post-procedure, mean decrease in AML size of 22 mm was seen after Onyx embolization (p = 0.0058, 95 % CI 9.13-34.87). No significant difference between serum creatinine was seen pre- and post-procedure (p = 0.54, 95 % CI 8.63-4.85).
Conclusions: Onyx embolization of renal AMLs is effective in the medium to long term, with theoretical benefits in safety and durability of result.

Background: To develop and test the performance of a fully automated system for classifying renal tumor subtypes via deep machine learning for automated segmentation and classification.
Materials And Methods: The model was developed using computed tomography (CT) images of pathologically proven renal tumors collected from a prospective cohort at a medical center between March 2016 and December 2020. A total of 561 renal tumors were included: 233 clear cell renal cell carcinomas (RCCs), 82 papillary RCCs, 74 chromophobe RCCs, and 172 angiomyolipomas.

Purpose: This retrospective study furthers our understanding of risk factors associated with hemorrhage and intervention in renal angiomyolipomas (R-AMLs), particularly in larger tumors (≥ 4 cm) and in childbearing-age (CBA; younger than 50 years) women. The objective was to refine risk stratification and optimize patient management.
Methods: Review of our institutional database identified patients with radiographic R-AML from 1997 to 2023.

This case report presents markedly different clinical and radiological manifestations of the same disease in a family over three consecutive generations with varying treatment strategies. The index case/proband primarily presented with gastrointestinal symptoms, including diarrhoea, bleeding per rectum and seizures. Further evaluation revealed bilateral renal angiomyolipoma and cerebral subependymal nodules, in conjunction with facial adenoma sebaceum, periungual fibromas and hypomelanotic ash-leaf macules.

Objective: To analyze clinical and radiological features and trends in the management pattern of renal angiomyolipomas (AML) in a tertiary care center over a 30-year period.
Patients And Methods: We retrospectively reviewed the charts of patients referred to our institutions from 1992 to 2022 with final diagnosis of AML. Demographics, clinical presentation, radiological findings, renal function status, and treatment options were recorded.

Gamna-Gandy (GG) bodies are sclerosiderotic nodules composed of iron pigment and calcium, that have been described predominantly in the spleens of patients with sickle cell disease. Their formal depiction in the kidney is mainly limited to case reports and small series. We aimed to investigate the incidence of GG bodies and associated clinicopathologic features in consecutive nephrectomies performed for renal tumors.
