Abstract:
Objective To investigate the imaging characteristics of female Skene-gland (periurethral glands) disease. Methods A retrospective analysis of preoperative imaging findings was performed in 15 female patients with surgical-pathological proven Skene gland disease. MRI scans were performed in 8 cases, CT scans were performed in 5 cases, both CT and MRI were performed in 2 cases. Imaging characteristics were observed and summarized.Results There were 3 types of diseases,including:(1) Skene gland cyst (n=3), located in the distal and posterolateral urethra or close to the proximity of urethra, presenting as cystic lesions with teardrop shape on sagittal images, which appeared as hypo-attenuation on non-enhanced CT, and hypo-intensity on T1WI, hyper-intensity on T2WI, and without enhancement. One case complicated with infection presented as hyper-intensity on T1WI and gaseous intensity inside,with thickened cystic wall and enhancement.(2)Urethral diverticulum communicating with Skene gland (n=10), located in the middle or distal and posterolateral urethra, presented as a horseshoe shaped cystic lesion partially surrounding the urethral(n=3)or spoke wheel-like cystic lesion with multiple septum completely surrounding the urethra (n=7). They appeared as fluid attenuation on unenhanced CT, and hypo-intensity on T1WI, hyper-intensity on T2WI and without enhancement. Heterogenous signal or attenuation and enhanced septum or cystic wall were found in 6 cases complicated with infection. (3) Malignant tumor (n=2, one adenocarcinoma and one neuroendocrine carcinoma), presented as cystic-solid mass surrounding the urethral, showing heterogenous low attenuation on nonenhanced CT and iso-to hyper-intensity on T2WI and hypo-to iso-intensity on T1WI with significant enhancement.Conclusions Female Skene-gland disease has specific occurrence location and imaging characteristics.
