How is pilonidal disease diagnosed?

Your doctor will begin by doing a full physical examination. A pilonidal infection should be visible by the naked eye. The doctor may see what looks like a pimple or oozing cyst. He or she may also ask you several questions, including:

  • Whether the cyst or pimple has changed in appearance
  • Whether it is draining fluid
  • Whether you have any other symptoms

Rarely, a CT scan may be ordered to look for sinus cavities under the surface of the skin.
