Role of Contrast Enhanced CT in Evaluation of Renal Tumors
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 2
Abstract
Introduction: CT scanning has completely revolutionalized the approach to the evaluation of renal tumors and has marked the arrival of a new era in diagnostic radiology. CT has the unique ability to produce anatomy of the kidneys in coronal plane which is well suited to evaluate intrarenal extent of the tumors as well as to evaluate the renal sinus and retroperitoneum. In addition renal perfusion, function and vascular nature of renal tumors can be easily assessed by dynamic CECT. There is a wide spectrum of findings in patients with renal tumors. The purpose of our study was to study in detail the morphology of the renal tumor; e.g. number, size, location, extent, shape, margins, calcifications, density, pattern, enhancement pattern at CECT. Material and methods: The study was carried out after approval from ethical committee of the institution. Forty patients who were diagnosed to have renal tumors by other modalities were included in the study. Contrast enhanced CT examination was performed for all these patients and the findings were evaluated. Results: In our study we came across renal cell carcinoma in 75% of cases, Wilms’ tumor in 10%, renal lymphoma in 5% angiomylipoma in 7.5% and transitional cell carcinoma in 2.5% cases. Conclusion: CT is a very versatile modality for evaluation of renal masses. The initial approach to a patient with a renal mass has to be ultrasound examination as it is cheap, easily available and quickly done. When one has a suspicion that the renal mass is likely to be malignant CT has to be the next step. The disadvantage of CT is that contrast examination is mandatory. Hence patients with deranged renal function cannot be adequately evaluated. The second drawback is the large radiation dose which the patient receives. In these conditions MRI can be a satisfactory alternative.
