What is Which among the following is not seen in Sturge Weber syndrome? and explain in detail?
The Sturge-Weber syndrome (SWS), also called encephalotrigeminal angiomatosis, is a neurocutaneous disorder with angiomas involving the leptomeninges (leptomeningeal angiomas ) and skin of the face, typically in the ophthalmic (V1) and maxillary (V2) distributions of the trigeminal nerve. The cutaneous angioma is called a po-wine stain (PWS). The neurologic manifestations include seizures, focal deficits, such as hemiparesis and hemianopsia, called "stroke like episodes"; headaches; and developmental disorders, including developmental delay, learning disorders, and mental retardation. The skull radiograph may show the classical "tram-line," or "tram-track" or "trolley-track," calcifications considered pathognomonic for SWS.
