Role of Ultrasonography and Color Doppler to Diagnosis of Pelvic Masses and its Correlation with Histopathological Findings

Background: Pelvic masses are quite common presentation of gynecological pathology. Ultrasonography (USG) is accepted as the primary imaging modality in the evaluation of pelvic masses, and provides the necessary information to plan out the right therapeutic approach required in the given situation. This study was conducted with a view to find out the diagnostic value of USG, color Doppler study, and correlate with histopathological diagnosis. Objectives: To study the ultrasonographic and color Doppler findings of pelvic masses, and compare its relative efficacies with histopathological diagnosis. Materials and Methods: A total of 50 patients were taken in the study referred from various departments. B-mode morphological criteria were used and subsequently spectral Doppler analysis was done by calculating resistive index (RI) and pulsatility index (PI) values. USG was performed by GE LOGIC P6 USG and GE-VIVID-E machine. International ovarian tumor analysis (IOTA) scoring system, RI and PI value was applied to differentiate benign and malignant pelvic masses. Results: Studied 50 cases, benign and malignant lesions were found in patients belongs to 30-50 and 50-70 years, respectively. Out of 50 cases, 47 cases (94%) were confirmed by histopathology. USG showed an overall sensitivity of 94% and specificity of 90% in comparison to the histopathological findings. For ovarian lesions, USG using IOTA scoring system showed 98% sensitivity and 94% specificity in comparison to the histopathological findings. Conclusion: USG is a very useful, highly diagnostic and a reliable method in the diagnosis of pelvic masses with good sensitivity and specificity.
