Signs & symptoms

It may take a while for you to notice these cysts unless they become large enough to feel or see them or rupture.


Pilar cysts are typically diagnosed by examining your scalp. Occasionally, your doctor may order a computed tomography (CT) or magnetic resonance imaging (MRI) scan to check your cyst's growth or to determine if it has grown into your skull.


For cyst removal, your head may have to be shaved. The surgery sites will be stitched up once the cysts have been removed. It may be necessary to examine your cysts under a microscope to make sure they aren't cancerous.
