Usually not needed: A sebaceous cyst arrises from a blocked oil gland in the skin. These are usually very superficial and can become quite large. The only time an ultrasound or other imaging (eg c/t scan) would be needed is if there is concern that it is some other type of deeper cyst.

No: If a mass is thought to be a sebaceous cyst on exam, there is no need for extra radiologic procedures prior to excisional biopsy.
