Suprasellar Tumors ; Definition, Causes, Symptoms, Diagnosis, Treatment

Suprasellar tumors are abnormal growths located above the sella turcica, a saddle-shaped depression in the sphenoid bone at the base of the brain. These tumors can affect vital structures such as the pituitary gland and optic nerves, leading to various symptoms1. Here are some common types of suprasellar tumors and their characteristics: Types of Suprasellar Tumors Pituitary Adenomas: Benign tumors originating from the pituitary gland. They can be classified as microadenomas (small) or macroadenomas (large) and may cause hormonal imbalances. Craniopharyngiomas: Tumors that develop from remnants of the craniopharyngeal duct. They can affect both children and adults and often cause vision problems and hormonal disruptions. Rathke’s Cleft Cysts: Fluid-filled sacs arising from embryonic tissue remnants near the pituitary gland. They are typically benign but can cause symptoms if they grow and exert pressure on nearby structures. Meningiomas: Tumors that develop in the meninges, the protective layers surrounding the brain and spinal cord. Suprasellar meningiomas can cause visual disturbances and hormonal imbalances. Germinomas: Rare tumors originating from germ cells, primarily affecting children and adolescents. They usually respond well to radiation therapy. Metastatic Lesions: Cancers that spread from other parts of the body to the suprasellar region. Identifying the primary cancer site is crucial for managing these metastatic lesions. Symptoms Visual Disturbances: Blurred vision, double vision, or loss of peripheral vision due to compression of the optic nerves. Hormonal Imbalances: Changes in hormonal levels due to compression of the pituitary gland, leading to issues such as growth abnormalities, weight changes, or irregular menstrual cycles. Headaches: Often due to increased intracranial pressure from the growing mass. Neurological Symptoms: Depending on the size and location of the tumor, it can cause various neurological symptoms. Diagnosis and Treatment Imaging: MRI and CT scans are commonly used to diagnose suprasellar tumors and assess their size and location. Treatment: Options include surgery, radiation therapy, and medications to manage symptoms and control tumor growth.
