Sturge-Weber syndrome (SWS) is a rare sporadic neurocutaneous syndrome characterized by angiomas involving the face, eyes, and brain (leptomeninges). Classical port-wine stains are seen in the ophthalmic and maxillary division of the trigeminal nerve. The most common presenting feature is seizures, the onset of which ranges from birth to late adulthood. Diagnosis is mainly done by brain radio imaging (CT scan and MRI with gadolinium contrast) where characteristic features of calcification and leptomeningeal enhancement are seen. We report a newly diagnosed case of SWS in a 31-year-old female patient who presented to our hospital with a complaint of generalized tonic-clonic (GTCS) type of convulsion two days prior to the admission with purple discoloration of the skin on the right side of the face, trunk, and right upper limb since birth. During the evaluation of past medical history, the patient was found to have a known case of epilepsy since the age of three months and on was on irregular treatment. To find out the cause of the seizure and skin lesions, further investigations were done which were suggestive of SWS in MRI and CT scanning of the brain. The patient was counseled about the syndrome and discharged on anti-convulsion treatment with advice for dye laser photocoagulation for port-wine stain. SWS is a rare sporadic genetic disease and diagnosis is primarily done by evaluating history, the presence of port-wine stain, and characteristic features on brain radio imaging. As no definitive treatment is available yet, patients are being treated by medical and surgical interventions for symptoms as well as for associated complications.
