Click 19-year-old female patient with a poorly differentiated with heterologous gastrointestinal epithelium Sertoli-Leydig cell tumor of the right ovary. Pelvic transvaginal ultrasound with a 10-MHz endocavitary probe. A heterogeneous complex-appearing mass, predominantly solid with focal cystic areas was detected in the right ovary. The tumor exhibited abundant and low resistance flow within the solid areas on color Doppler imaging. These sonographic characteristics combined with a small amount of pelvic ascites suggested a probably malignant nature.

Click 19-year-old female patient with a poorly differentiated with heterologous gastrointestinal epithelium Sertoli-Leydig cell tumor of the right ovary. Pelvic Magnetic Resonance Imaging. Axial T1-weighted images. show a well-defined tumor of the right ovary. The tumor was well encapsulated, with the exception of a protruded eccentric anterior segment. Solid components showed T1 signal intensity similar to muscle while cystic components showed low signal on T1-weighted images [Philips Intera Pulsar 1.5T: T1-weighted images (TR=604; TE=10)]

Click 19-year-old female patient with a poorly differentiated with heterologous gastrointestinal epithelium Sertoli-Leydig cell tumor of the right ovary. Pelvic Magnetic Resonance Imaging. Axial T2-weighted images show a well-defined tumor of the right ovary. The tumor was well encapsulated, with the exception of a protruded eccentric anterior segment. Solid components showed intermediate T2 signal intensity while cystic components showed high signal on T2-weighted images [Philips Intera Pulsar 1.5T: T2-wheighted images (TR=3500; TE=100)].

Click 19-year-old female patient with a poorly differentiated with heterologous gastrointestinal epithelium Sertoli-Leydig cell tumor of the right ovary. Pelvic Magnetic Resonance Imaging. Axial gadolinium-enhanced fat-suppressed T1-weighted images showed avid contrast uptake by the solid components of the tumor without enhancement of the cystic components [Philips Intera Pulsar 1.5T: Dynamic contrasted-enhanced image obtained with a 3-dimensional gradient- recalled echo T1-weighted sequence after the administration of 0.1mmol/kg of gadopentetate dimeglumine at a rate of 2mL/sec acquired 2 minutes after injection]
