Цель: Ознакомить читателей с многообразием отображения онкоцитом почек по данным КТ и МРТ.

Материалы и методы

Материалы и методы: Статья основана на одном из самых крупных клинических материалов, отражающим многоликость проявлений онкоцитом почек у 61 пациента по данным предоперационных КТ/МРТ исследований брюшной полости с внутривенным контрастированием. Всем пациентам выполнено оперативное вмешательство (резекция почки или нефрэктомия) с морфологическим изучением удаленных макропрепаратов.

Результаты

Результаты: Значительное разнообразие вариантов отображения онкоцитом базируется на неоднородности их морфологического строения: заметном различии в клеточности опухолей, выраженности стромы, наличия геморрагических и/или кистозных элементов. Именно поэтому их проявления могут отчетливо напоминать различные варианты почечно-клеточного рака (светло-клеточного, хромофобного и др.), что значительно затрудняет корректную дооперационную диагностику онкоцитом с помощью стандартных лучевых методов исследования (УЗИ, КТ, МРТ). Характерный для онкоцитом симптом «колеса со спицами» выявлен нами только в 4 из 61 наблюдения.

Заключение

Заключение: Дифференциальная диагностика онкоцитом и почечно-клеточного рака по данным КТ/МРТ в большинстве наблюдений обычно крайне затруднена, но в отдельных случаях все-таки возможна.

Introduction

Introduction: The effectiveness of adjuvant radiation therapy used to consolidate the effect of chemotherapy in patients with

Purpose

Purpose: To familiarize readers with the diverse imaging features of renal oncocytomas as seen on 4-phase CT/MRI contrast-enhanced study.

Materials and methods

Materials and methods: This article is based on one of the largest clinical data, reflecting the wide variety of imaging features of renal oncocytoma in 61 patients who underwent preoperative 4-phase CT/MRI contrast-enhanced study of the abdomen, followed by surgical intervention (resection or nephrectomy) and morphological examination of the resected specimens.

Results

Results: The significant diversity in the imaging patterns of oncocytomas depends on the heterogeneity of their morphological structure: marked differences in tumor cellularity, the volume of stroma, and the presence of hemorrhagic and/or cystic elements. This is why their imaging manifistations can overlap with the features of various types of renal cell carcinoma (clear cell, chromophobe cell, etc.), which significantly complicates the accurate preoperative diagnosis of oncocytoma using standard imaging methods (ultrasound, CT, MRI). The well-known and characteristic oncocytoma’s pattern “a spoke-wheel-like enhancement” we observed in only 4 of 61 patients.

Conclusion

Conclusion: Differential diagnosis between oncocytoma and renal cell carcinoma based on CT/MRI findings can be extremely difficult in most cases, but is still possible in a few patients.
