The Role of CT in Differentiating the Non Pediatric Renal and Adrenal Region Fatty Masses

Abstract Background CT is indicated in many abdominal conditions because of its excellent morphological resolution and its ability to image many different structures, such as abdominal viscera, pelvic organs, lungs and bones, with a single examination. Aim of the Work The aim of this study is to highlight the accuracy of multi-detector computed tomography scan in diagnosing the different fatty lesions of the renal and adrenal regions by comparing the CT study of the benign lesions with their follow up CT scan and comparing the CT study of the malignant cases with their histo-pathological results. Patients and Methods The study was conducted on 34 patients most of them had unrelated complaints(incidental findings) and were referred to Radiology department, Theodor Bilharz Research Institute. Their age ranged from 20 years to 81 years old (mean age 56.35 years±13.61). Most of the patients were males 21cases while female were 13 cases. The patients were referred from oncology, general surgery, and urology departments of Theodor Bilharz Research Institute hospital as well as the outpatient clinics to perform MDCT in the period from September 2021 to June 2022. Results MDCT examinations were done for 34 patients and concluded that MDCT should be used in the first place in the course of diagnostic procedures of patients with renal and adrenal region fatty lesions and this was justified by an overall diagnostic accuracy of 100% for benign lesions and 82% for malignant lesions, where MDCT could correctly diagnose (33/34) cases and only 1 case was misdiagnosed, confirming the ability of MDCT to show up the accurate diagnosis, the exact location, extent of tumor, along with involvement of adjacent organs and vessels. Conclusion It also has a high accuracy in differentiation of malignant from benign lesions and detection of lymph node involvement & metastasis. There by improving the prognosis.
