H47.632

Clinical Causes: Primary brain tumors located in the left occipital lobe or adjacent regions affecting the visual cortex. Metastatic tumors originating from other parts of the body that spread to the brain's left hemisphere. Infiltrative neoplasms that invade the visual processing areas of the brain. Other medical conditions that lead to tumor growth in areas of the brain responsible for vision.

Key Symptoms: Visual field deficits, such as loss of vision in certain areas of the visual field, often affecting the right visual field due to the left brain involvement. Difficulty recognizing objects or people (visual agnosia). Problems with visual processing, including challenges with spatial orientation. Possible accompanying neurological symptoms depending on the size and location of the tumor, such as headaches, seizures, or weakness on one side of the body. Altered perception of color or motion.

Diagnosis Path: Magnetic Resonance Imaging (MRI): Provides detailed images of the brain and can identify tumors, their size, and location. Computed Tomography (CT) scans: Useful for detecting tumors and planning further evaluation. Neurological assessments: Tests to evaluate visual fields, visual acuity, and other brain functions. Biopsy procedures: Sometimes performed to determine the type of tumor causing the lesion.

Treatment Protocols: Surgical removal: Often the first-line treatment if the tumor is accessible and operable, aiming to excise as much of the tumor as possible. Radiation therapy: Used to shrink or eliminate tumor cells, especially if surgery is not feasible or as an adjunct to surgical treatment. Chemotherapy: Medications may be used to target dividing tumor cells, sometimes in combination with surgery and radiation. Targeted therapy and immunotherapy: Emerging treatments designed to attack specific tumor characteristics. Supportive care: Includes strategies for managing symptoms and maintaining quality of life, such as vision therapy or physical therapy.
