An ovarian volume greater than 22 cc in a premenopausal patient is considered

• A. Normal
• B. Abnormal
• C. Indeterminate
• D. Inconclusive

Answer: (B)

Ovarian size on ultrasound is used to distinguish normal from enlarged ovaries in premenopausal women. There is a generally accepted upper limit for normal ovarian volume in this group, roughly around 20 mL. When the measured ovarian volume exceeds about 22 mL, it crosses that upper reference and is considered enlarged, i.e., abnormal. This finding prompts consideration of conditions such as functional cysts, persistent cystic structures, or ovarian masses, and often leads to follow-up imaging or clinical correlation to determine if the enlargement is transient or represents a pathology. The volume is typically calculated from the three measured dimensions using the ellipsoid formula (length × width × thickness × 0.523) to standardize assessment.
