Ovarian Cysts are a common finding in women of reproductive age. Most of them are benign (not cancerous) and are diagnosed by the means of a pelvic ultrasound. Benign cysts may be simple in nature, haemorrhagic, endometriotic or dermoid.
Simple ovarian cysts and haemorrhagic cysts (particularly those less than 5cm in diameter) will often go away by themselves with no need for intervention. Endometriotic cysts and dermoid cysts will not resolve themselves and will need surgical treatment to remove them.
Most ovarian cysts can be removed from the ovary by means of keyhole surgery with purely removal of the cyst so that the ovarian tissue remains intact. If a dermoid cyst is suspected on ultrasound, an MRI scan can be used to confirm the diagnosis.
Occasionally a cyst in the ovary shows suspicious features and a blood test is taken for CA 125 level and an MRI scan is performed to further evaluate the cyst.
