This case report describes the clinical, laboratory, and imaging findings of a 5-year-old male patient with SWS type III who presented with recurrent headaches and convulsions for 1 year. No facial hemangioma was noted on physical examination. Laboratory tests revealed mild hyperammonemia (29.4\u2005\u03bcmol\/L; reference range: 10\u201327\u2005\u03bcmol\/L) and low pyruvate (18\u2005\u03bcmol\/L; reference range: 20\u2013100\u2005\u03bcmol\/L). Video electroencephalogram showed diffuse slow wave elevation, and cranial CT\/MRI confirmed leptomeningeal capillary malformations with calcifications in the left occipital lobe (no cerebral atrophy). The patient was diagnosed with SWS type III based on clinical and imaging findings, and his symptoms were well-controlled with symptomatic treatment. This case highlights the importance of imaging modalities in diagnosing SWS type III in pediatric patients with non-specific neurological symptoms, and emphasizes the favorable prognosis of early-detected cases with short disease courses.<\/jats:p>","DOI":"10.3389\/fradi.2026.1767963","type":"journal-article","created":{"date-parts":[[2026,3,12]],"date-time":"2026-03-12T06:46:58Z","timestamp":1773298018000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Sturge-Weber
