TRANSITIONAL MENINGIOMA Meaning and
Definition
-
Transitional meningioma is a specific type of brain tumor that arises from the meninges, the protective membranes covering the brain and spinal cord. Meningiomas account for approximately 15 to 20 percent of all primary intracranial tumors and are classified into several subtypes, including the transitional meningioma.
Transitional meningioma is characterized by its histological appearance, which displays a combination of features found in both the fibrous and meningothelial subtypes. This intermediate-grade tumor typically presents as a slow-growing, benign neoplasm, although it can occasionally exhibit more aggressive behavior.
Clinically, patients with transitional meningioma may experience symptoms that are dependent on the location and size of the tumor. Common signs and symptoms include headaches, seizures, visual disturbances, cognitive impairment, and focal neurological deficits. Diagnosis is typically achieved through imaging techniques such as magnetic resonance imaging (MRI) or computed tomography (CT) scans.
Treatment options for transitional meningiomas depend on various factors, including the size, location, and grade of the tumor, as well as the patient's overall health. In many cases, surgical removal of the tumor is the primary treatment modality. However, radiation therapy may be employed before or after surgery to enhance tumor control. The use of chemotherapy in managing transitional meningiomas is limited, as these tumors tend to be less responsive to traditional chemotherapy agents.
Regular follow-up and monitoring are crucial in managing transitional meningiomas, as the recurrence rate can vary depending on individual factors. Prognosis for patients with transitional meningioma generally tends to be favorable, with a high chance of long-term survival. However, the overall outcome can be influenced by factors such as tumor grade, location, and the extent of surgical resection.

Etymology of TRANSITIONAL MENINGIOMA
The word transitional in transitional meningioma refers to the histological appearance of the tumor, which exhibits transitional features between two other types of meningioma: fibrous and psammomatous. It is not directly related to the etymology of the term.
However, the word meningioma itself has a specific etymology. It is derived from the Greek word meninx, which means membrane or meninges (the protective layers covering the brain and spinal cord), and the suffix -oma, which denotes a tumor or mass. Combining these, meningioma literally translates to tumor of the meninges.
