Abstract

Purpose: This study aimed to describe the imaging characteristics on multidetector computed tomography (MDCT) of primary renal cell carcinoma (RCC). Object and Method: A descriptive study was conducted on the MDCT imaging features of 80 patients with primary RCC who were treated at K3 Tan Trieu Hospital from January 2025 to May 2025. Results: Primary RCC was more common in male patients, with a male-to-female ratio of approximately 1.3:1. The mean age was 56.98 ± 14.29 years (range: 13–86), with the majority of cases (70%) occurring in the 40–70 age group. Tumors were found in various anatomical regions of the renal parenchyma, with no significant difference in laterality between the left and right kidneys (p > 0.05). Most tumors had well-defined margins and relatively clear boundaries, although some showed irregular borders, reflecting morphological variability. The majority of tumors exhibited localized extension (63.75%), while the rates of invasion into distant structures such as Gerota’s fascia, adrenal glands, and the venous system were considerably lower. Conclusion: MDCT plays an essential role in the diagnosis of primary RCC by clearly identifying tumor location, margins, and extent of invasion. Most lesions were locally advanced with limited distant spread, demonstrating the effectiveness of MDCT in staging the disease, guiding appropriate treatment planning, and improving patient prognosis.
