Lateral Sulcus Tumors

Lateral sulcus tumors are abnormal growths that occur in the brain’s lateral sulcus, also known as the Sylvian fissure. These tumors can vary in size and severity and may cause a range of symptoms depending on their location and type. Understanding the causes, symptoms, diagnosis, and treatment options for lateral sulcus tumors is crucial for effective management and prevention of complications.

Lateral sulcus tumors are growths that develop in the lateral sulcus of the brain, which is a groove that separates the frontal and parietal lobes from the temporal lobe. These tumors can be benign (non-cancerous) or malignant (cancerous) and may originate from various types of cells present in the brain tissue.

Types of Lateral Sulcus Tumors:
