OBJECTIVE: To determine the natural history and to estimate the risk of @entity43 less than 10 cm in diameter followed conservatively by transvaginal ultrasound. METHODS: From 1987 to 2002, 15,106 asymptomatic @entity1 at least 50 years old entered the University of Kentucky's @entity43 Screening Program and underwent initial transvaginal ultrasonography. If the screen revealed nothing abnormal, @entity1 were asked to repeat transvaginal ultrasonography yearly. If the screen revealed abnormalities, transvaginal ultrasonography was repeated in 4 to 6 weeks, along with Doppler flow ultrasonography and CA 125 testing. RESULTS: Of the 15,106 @entity1 at least 50 years old, 2763 @entity1 (18%) were diagnosed with 3259 unilocular @entity42 . A total of 2261 (69.4%) of these cysts resolved spontaneously, 537 (16.5%) developed a septum, 189 (5.8%) developed a solid area, and 220 (6.8%) persisted as a unilocular lesion. During this time, 27 @entity1 received a diagnosis of @entity43 , and ten had been previously diagnosed with simple @entity42 . All ten of these @entity1 , however, developed another @entity154 , experienced resolution of the cyst before developing @entity5 , or developed @entity5 in the contralateral ovary. No @entity1 with an isolated @entity43 has developed @entity43 in this population. CONCLUSION: The risk of @entity43 less than 10 cm in diameter in @entity1 50 years old or older is extremely low. The majority will resolve spontaneously and can be followed conservatively with serial transvaginal ultrasonography.
