Sturge-Weber Syndrome Type III

Sturge-Weber syndrome (SWS) is a neurogenetic disease with an incidence of 1 in 20.000-50.000 live births. The less common form, which can be difficult to diagnose and only involves leptomeningeal angioma, has been defined as Type III SWS. A 5.5-month-old male patient with normal neuromotor development presented with right sided partial seizures, which had been occurring frequently for the previous two days and could not be controlled. A cranial magnetic resonance imaging showed pathological contrasts in the cortical regions involving the left hemisphere and in the leptomeningeal structures. We aim to present the case of an infant with SWS, which unlike the classical form was unidentifiable in physical examination and diagnosed using imaging methods.
