PREOPERATIVE EVALUATION OF INTERSEX PATIENTS WITH PELVIC MAGNETIC-RESONANCE-IMAGING IN SEARCH OF Y-CHROMOSOME-BEARING GONADAL TISSUE

Objective: To illustrate the utility of preoperative magnetic resonanc e imaging in the evaluation of intersex patients who require gonadecto my. Design: Case reports of two phenotypic females having karyotypes c ontaining a Y chromosome whose preoperative evaluation included pelvic magnetic resonance imaging. Setting: Tertiary academic referral cente r. Main Outcome Measure: Pelvic magnetic resonance imaging for gonadal localization. Results: Preoperative evaluation with magnetic resonanc e imaging correctly identified the most appropriate surgical approach to gonadectomy. Conclusions: Pelvic magnetic resonance imaging can be useful in the preoperative evaluation of intersex patients having nonp alpable Y chromosome-bearing gonadal tissue.
