Assessment of Masses in the Right Upper Quadrant using Ultrasound Imaging: A Comprehensive Diagnostic Approach for Clinical Evaluation in Bangladesh

Abstract

Ultrasound serves as a pivotal tool in identifying and assessing masses in the right upper quadrant (RUQ) of the abdomen, crucial for determining precise organ involvement, composition, characteristics, and extension into neighboring structures. This cross-sectional prospective study conducted at various medical facilities in Dhaka enrolled 130 patients, utilizing real-time ultrasound with a 3.5MHz transducer. Among the 100 patients with abnormal sonographic findings, 40% exhibited RUQ masses, predominantly affecting males (75%). Liver masses were most common (75%), including abscesses, hepatocellular carcinomas, secondary lesions, hemangiomas, and simple cysts. Gall bladder masses (10%) mostly consisted of advanced stage carcinomas and polyp-like masses. Right renal masses (15%) comprised simple cysts, severe hydrone-phrosis, renal cell carcinoma, and angiomyolipoma. Ultrasound emerges as the preferred initial imaging modality for RUQ mass detection, offering high diagnostic accuracy, non-invasiveness, affordability, and widespread availability. While supplementary investigations like serological tests, CT scans, and histopathology may be necessary for definitive diagnoses, ultrasound aids in formulating initial patient management guidelines. Despite its limitations, ultrasound remains popular and highly preferred for RUQ imaging, emphasizing its significance in clinical practice.
