Example: "My daughter has severe acne. She has also recently gained a lot of weight. Why is the dermatologist asking her to get an ultrasound done? What is the connection? I am worried about this."
Discussion:
The girl above has severe acne and a history of weight gain. These are two common symptoms in a person with Polycystic Ovarian Syndrome or PCOS. It is likely that the ultrasound was recommended to screen for PCOS, wherein the ovaries may show multiple small cysts. However, not all patients with these symptoms have PCOS and not all patients with PCOS show these symptoms or have any changes in the ultrasound. Thus the ultrasound is only part of the PCOS work up and must be correlated clinically with history and examination.

Multiple small cysts seen in the ovary around a dense pattern, called the 'String or Pearls' sign which indicates the presence of PCOS in the individual. It however is only one sign of PCOS and does not dictate all the symptoms of the person.
One must not be unduly concerned about being asked to undergo an ultrasound and should discuss the above with the dermatologist/treating physician. If the doctor is considering PCOS as a diagnosis they may also recommend various blood tests and a detailed menstrual history along with the ultrasound to gain a complete picture. With a complete diagnosis, it would be possible to offer a far superior and more effective treatment for all concerns.

ULTRASOUND CRITERIA FOR MAKING A DIAGNOSIS OF PCOS:
PCOS does not have a single definitive picture but occurs as a cluster of symptoms and signs. Women with the condition may have all/some/none of the symptoms associated with PCOS with or without ultrasound evidence of PCOS. Several studies have highlighted that the criteria used to establish the diagnosis of PCOS remain controversial. The revised diagnostic criteria proposed in 2003 at the Rotterdam European Society of Human Reproduction and Embryology/American Society of Reproductive Medicine consensus workshop stated ultrasound polycystic ovarian morphology (PCOM) be necessary to establish the diagnosis of PCOS. A recent study funded by Cornell University noted that the existing Rotterdam criteria for diagnosis of PCOS using did not adequately and specifically cater to all groups of women with PCOS.
