**Question:** Sturge Weber syndrome is associated with:

A. Portal hypertension
B. Glomus tumor
C. Epilepsy
D. Hemangioma

**Core Concept:** Sturge Weber syndrome (SWS) is a rare congenital disorder characterized by a port-wine birthmark (nevus flammeus) and neurological abnormalities. It is a neurocutaneous syndrome caused by a genetic mutation affecting the GNAQ gene, which leads to abnormal angiogenesis and vascular dysregulation.

**Why the Correct Answer is Right:** Sturge Weber syndrome is associated with C (Cerebral involvement) as the primary feature of the condition. The port-wine birthmark (nevus flammeus) and glomus tumor (option B) are secondary manifestations. Portal hypertension (option A) is not related to this condition, as it is a complication of liver cirrhosis or portal vein obstruction, not SWS. Hemangioma (option D) is a benign vascular tumor, while SWS is a genetic disorder involving abnormal angiogenesis.

**Why Each Wrong Option is Incorrect:**

A. Portal hypertension: This complication is caused by liver cirrhosis or portal vein obstruction, not Sturge Weber syndrome. Portal hypertension is not a feature of SWS.

B. Glomus tumor: Although glomus tumors can occur in patients with SWS, they are not the primary feature of the syndrome. Sturge Weber syndrome is characterized by port-wine birthmark (nevus flammeus) and cerebral involvement (option C).

C. Epilepsy: Sturge Weber syndrome is associated with neurological abnormalities, which often include epilepsy. Epilepsy is a common feature of SWS.

D. Hemangioma: As mentioned earlier, hemangioma is a benign vascular tumor, while SWS is a genetic disorder affecting angiogenesis. Hemangiomas are not a feature of Sturge Weber syndrome.

**Clinical Pearl:** Sturge Weber syndrome is a rare neurocutaneous disorder characterized by port-wine birthmark, glomus tumors, and cerebral angiomatosis (abnormal angiogenesis in the brain) leading to neurological complications like epilepsy, cognitive impairment, and visual deficits. Early diagnosis and management are essential to improve the patient's quality of life and prevent complications.
