Skene duct cyst

Skene duct cyst is a retention cyst that forms secondary to inflammatory obstruction of the paraurethral ducts (Skene ducts) in females.

They are lined by stratified squamous epithelium due to their origin from the urogenital sinus.

Usually asymptomatic.

MRI

Typically appear as round or oval masses that are located just laterally to the external urethral meatus and inferior to the pubic symphysis.

On MR imaging, Skene duct cysts manifest as round or oval hyperintense lesions just lateral to the external urethral meatus.

Signal characteristics include:

  • T2
    • hyperintense signal if uncomplicated
    • may show fluid-fluid levels if there is a complicating haemorrhage 1

Large, symptomatic cysts warrant surgical excision or marsupialisation, usually with excellent outcome. May also require drainage or excision in the presence of superimposed infection.
