Struma Ovarii : A Rare Monodermal Teratoma

Struma ovarii is a rare tumor of ovary which accounts for 1% of all ovarian tumors and 3% 0f all dermoid tumors. It belongs to the group of monodermal teratomas. We present a case of struma ovarii in a 55 year old women who presented with symptoms of pain in lower abdomen and loss of appetite for the last one month. Radiological investigations including USG, CT scan and MRI revealed a complex right adnexal lesion. Final diagnosis of struma ovarii was made on histopathological examination which revealed colloid filled thyroid follicles lined by cuboidal epithelium. JMS 2017; 20(1):41-43

Cystic adnexal lesion on USG – causing a diagnostic dilemma in oncology institute

Adnexal lesions are one of the most common cause of gynecological complains, including possibility of ectopic pregnancy in reproductive age group. Ultrasound is the first imaging modality used for evaluation of adnexal lesions. On ultrasound large non-adnexal lesions can be confused as adnexal lesions causing a diagnostic dilemma, rendering use of cross-sectional imaging mandatory. We present a case of middle-aged female who was diagnosed with a right adnexal lesion (possibly malignant) on ultrasound, but on further evaluation was found to be suffering from a benign non-adenexal etiology.

Case 11.5

27-year-old woman with left lower quadrant pain and a history of endometriosis Axial FSE T2-weighted images (Figure 11.5.1) demonstrate a large, lobulated left adnexal lesion with regions of high and low signal intensity. Coronal fat-suppressed FSE T2-weighted images (Figure 11.5.2) reveal similar findings. Coronal fat-suppressed FSE T1-weighted images (...

Case 11.12

46-year-old woman with pelvic pain and dysuria; pelvic US demonstrated an adnexal mass Axial fat-suppressed FSE T2-weighted images (Figure 11.12.1) demonstrate a large right adnexal lesion with moderately high signal intensity except for a small anterior component. Axial FSE T1-weighted image (...

Case 11.8

50-year-old perimenopausal woman with intermittent mild abdominopelvic pain Fat, water, IP, and OP images from a 3D SPGR Dixon acquisition (Figure 11.8.1) reveal a posterior right adnexal lesion with a fluid-fluid level. The anterior nondependent layer is lipid, which appears bright on the fat image and dark on the water image. Notice also the chemical shift artifact appearing at the fat-fluid interface on the OP image....
