Symptoms Of A Nevus Sebaceous

Hemimegalencephaly

The majority of individuals with nevi sebaceous do not suffer from any symptoms besides discolored, hairless, or textured skin. However, in rare cases, patients may deal with linear nevus sebaceous syndrome. This is a type of unusual genetic disorder that causes individuals to get a large nevus sebaceous along with other issues. One potential symptom of linear nevus sebaceous syndrome is hemimegalencephaly, which is a type of neurological issue where one part of the brain is far larger than the other side. The brain malformation may cause the head itself to be enlarged or asymmetrical. It can occasionally occur without any marked impairments, but some patients who have this condition have motor deficits or movement difficulties on the side of the body controlled by the affected half of the brain. This means an individual with an enlarged right half of the brain might struggle to move their left arm and leg.
