Polycystic ovarian disease: sonographic spectrum.

Twenty-eight patients with polycystic ovarian disease (PCOD) as determined by hormonal analysis (with surgical confirmation of the diagnosis in 12 cases) underwent ultrasound examinations. Twenty-nine per cent of patients had normal ovarian volume. Normal ovarian size does not exclude the diagnosis of PCOD in the proper clinical setting. The remaining 71% of patients with PCOD had bilaterally enlarged ovaries in three distinct patterns: discretely resolved cysts (39%), hypoechoic (25%), and isoechoic to the uterus (7%). Understanding the sonographic spectrum of ovarian morphology in PCOD can aid in diagnostic evaluation of this condition in patients who may have a varied clinical presentation.
