  •   Objective  To analyze the clinical manifestations and neuroimaging characteristics of Sturge-Weber syndrome (SWS), to describe the manifestations of facial port-wine stains (PWS) of SWS, and to explore the screening opinions for SWS.
      Methods  A retrospective analysis was performed on the general condition, clinical manifestations, and neuroimaging results of 24 SWS patients from the dermatology department of West China Hospital of Sichuan University between 2017 and 2019. Three different facial PWS distribution methods (traditional anatomical distribution, facial trigeminal nerve distribution, and facial embryological vasculature distribution) in SWS patients were Analysed.
      Results  Among the 24 patients, 50% were male and 50% were female, with an average age of (18.9±14.0) years (range 1 to 54 years old). 12 cases were SWS type Ⅰ, and the other 12 cases were type Ⅱ. All patients had facial PWS at birth, and the facial PWS of 13 cases (54.2%) were thickened. According to the anatomical division, all the PWS involved the upper and middle face (above the oral commissure); according to the trigeminal nerve distribution, 100% (24/24) patients involve the V2 area; according to the distribution of facial embryological vasculature, 95.8% (23/24) of the patients involved frontal region. 22 patients had ophthalmic abnormalities, the most common was glaucoma (70.8%), and 4 patients had a history of epilepsy. The typical neuroimaging presentations of SWS include leptomeningeal enhancement, cortical calcification, enlarged choroid plexus, focal cerebral atrophy, abnormal intracranial vessels, and local thickening of the skull.
      Conclusion  Early intervention is recommended for facial PWS in patients with SWS , and ophthalmological screening should be performed on children with PWS found in any part of the upper and middle face after birth. Moreover, neuroimaging examination (MRI) for patients with high suspicion of SWS should be performed after 1 year old, and regular ophthalmological examination and intraocular pressure measurement is necessary.
