Cyst Aspiration

A cyst aspiration uses a thin needle to drain fluid from benign (non-cancerous) fluid-filled cysts. This procedure is performed using ultrasound-guidance to ensure accurate placement of the needle into the cyst.

As our patient, we are committed to making your experience as easy and comfortable as possible and providing the medical answers needed to guide your care.


Learn more about what to expect with this procedure:

  • We will call you prior to your appointment to provide you with specific instructions and review health and insurance information.
  • Please bring previous images you have had to the appointment, including ultrasound, mammography and MRI exams or provide the name, address and contact information of the place where you had the exams done. The radiologist may need your previous films for comparison in order to make an accurate assessment.
  • Please notify a member of our staff if you are nursing or if there is a chance you may be pregnant.
  • This exam usually takes about 30 minutes.
  • The technologist will position you for the easiest access to the area for aspiration.
  •  A local anesthetic is used to numb the area where the needle will be inserted.
  • The radiologist will use ultrasound imaging to ensure the cyst is properly targeted.
  • The radiologist then inserts a tiny, hollow needle and positions it in location of the cyst.
  • Once the needle is in the proper position, the fluid will be withdrawn (aspirated) into a syringe. If the fluid has an unusual appearance, it may be sent to a pathology lab for evaluation.
  • Once the aspiration is complete, the needle is removed, pressure will be applied, and the skin is covered with a dressing.

Ask a member of our staff for more specific information on when and how you will receive your results. However, in general you can expect:

  • You may experience some slight bruising.
  • A report is prepared for your referring provider. Follow-up with them directly regarding next steps for your care.
