A case of possible Susac syndrome with avascular necrosis of hip

Susac syndrome (SuS) is a rare autoimmune micro-angiopathic endotheliopathy. The diagnosis of SuS is a challenge to neurologists because of the diversity of symptoms and rarity of occurrence of classical triad of SuS. In this context, a plethora of immunological/demyelinating disorders can mimic the features of neurological manifestations of SuS. The detection of snowball corpus callosal lesion is unique to SuS. A high degree of suspicion is the key to diagnosis and early immunomodulator therapy can prevent catastrophic disabilities. The use of steroid-sparing medications should be advocated wherever possible. In this case report, we tried to explore a 20 year old female with headache, seizure, irritability, blurring of vision with right hip pain and emphasize the need for awareness of this rare entity along with high element of suspicion for detection of such disorders.
