Multidetector computed tomography scan for renal cell carcinoma: A review

ABSTRACT

Renal cell carcinoma (RCC) is the most common renal malignant tumour. Owing to its retroperitoneal location, RCC remains asymptomatic and non-palpable until advanced disease develops. Most cases are identified during radiological examination for other reasons. The management of RCC depends substantially on the effective use of imaging. This is true in all the stages of the RCC, from initial diagnosis to follow-up. This article sets to review the current knowledge about multidetector computed tomography (MDCT) scan and how it characterises the RCC. A search of PubMed database was made to locate the original and review articles in English that address the MDCT scan or RCC, without limit to publication date. Relevant articles and textbook chapters were reviewed, analysed and summarised. MDCT reveals the renal tumour, its extent, venous involvement, status of loco-regional lymph nodes as well as adrenal and liver extension. It is available and relatively affordable presently in some centres across the subregion. MDCT is an essential tool that has aided not only the early diagnosis of RCC, but also the staging and characterisation of the RCC
