The diagnostic puzzle: Meigs' syndrome, pseudo‐Meigs' syndrome and ovarian cancer

The data that support the findings of this study are available from the corresponding author upon reasonable request. Figure S1 Grayscale transvaginal (a) and transabdominal (b,c) ultrasound images of benign struma ovarii associated with pseudo-Meigs' syndrome, showing (a) irregular solid mass with acoustic shadowing, hyperechoic tissue and cystic areas, (b) pleural effusion in abdomen and (c) ascites in abdomen. Figure S2 Macroscopic (a,c,e) and microscopic (hematoxylin and eosin stain) (b,d,f) images of ovarian masses: benign struma ovarii associated with pseudo-Meigs' syndrome (a,b), benign ovarian fibroma associated with Meigs' syndrome (c,d) and high-grade serous ovarian carcinoma (e,f). Figure S3 Grayscale transabdominal (a,c,d) and transvaginal (b) ultrasound images of benign ovarian fibroma associated with Meigs' syndrome, showing regular solid mass (calipers) with acoustic shadowing (a,b). Ascites (c) and free fluid (d) are visible in the pouch of Douglas. Figure S4 (a–c) Grayscale transvaginal ultrasound images of high-grade serous ovarian carcinoma, showing (a) irregular solid mass with inhomogeneous echotexture due to irregular cystic areas and (b,c) hypoechoic solid tissue infiltrating the pelvic peritoneum in the pouch of Douglas. (d,e) Grayscale transabdominal ultrasound imaging showing presence of ascites. Videoclip S1 Grayscale transvaginal ultrasound showing solid mass in left adnexa, histologically confirmed as benign struma ovarii, accompanied by ascites, consistent with pseudo-Meigs' syndrome. Videoclip S2 Transvaginal color Doppler ultrasound showing solid mass with moderate vascularization, histologically confirmed as benign struma ovarii, accompanied by ascites, consistent with pseudo-Meigs' syndrome. Videoclip S3 Grayscale transvaginal ultrasound showing left adnexal solid mass, histologically confirmed as benign ovarian fibroma, accompanied by ascites, consistent with Meigs' syndrome. Videoclip S4 Grayscale transvaginal ultrasound showing pelvic appearance of malignant solid ovarian tumor, diagnosed as high-grade serous ovarian carcinoma, with ascites. Videoclip S5 Transvaginal color Doppler ultrasound showing malignant solid ovarian tumor with moderate vascularization, diagnosed as high-grade serous ovarian carcinoma.
