Subependymal nodules are small, benign growths that can occur in the brain. They are typically found lining the ventricles, the fluid-filled spaces within the brain. These nodules are composed of glial cells, which are the supportive cells of the nervous system. Subependymal nodules are generally asymptomatic and are often discovered incidentally during imaging studies performed for other reasons.

The exact cause of subependymal nodules is not fully understood, but they are believed to be a developmental anomaly. In some individuals, they can be associated with certain genetic conditions, such as tuberous sclerosis complex. However, in most cases, they occur sporadically without any known underlying disorder.

Diagnosis of subependymal nodules is typically made through neuroimaging techniques like MRI or CT scans. The appearance of these nodules on imaging is characteristic, allowing for differentiation from other brain lesions. Treatment is usually not required as they are benign and do not typically cause symptoms or affect brain function. In rare instances where a nodule might grow or cause obstruction, surgical removal could be considered, but this is uncommon. Regular monitoring through follow-up imaging may be recommended by a physician, especially if there is an associated condition.
