Brain Tumours
A brain tumor is an abnormal growth of cells in or around the brain. Some brain tumors are benign (non-cancerous), while others are malignant (cancerous).
Dr. Sanjeev Srivastava is a neurosurgeon with extensive expertise in neuro-oncology. He specializes in the surgical management and comprehensive care of complex primary and metastatic brain tumors.
Primary Brain Tumor Conditions Treated
Gliomas & Glioblastoma (GBM): Infiltrative primary brain tumors ranging from low-grade astrocytomas and oligodendrogliomas to aggressive high-grade glioblastoma multiforme. Surgical resection focuses on maximum safe debulking to relieve mass effect.
Meningiomas: Typically slow-growing tumors arising from the meningeal layers surrounding the brain. Microsurgical resection aims for complete removal while preserving adjacent cranial nerves and vascular structures.
Pituitary Adenomas: Tumors originating in the pituitary gland that can compress the optic chiasm and alter hormone regulation. Managed using minimally invasive endoscopic endonasal approaches.
Acoustic Neuromas (Vestibular Schwannomas): Benign tumors arising along the vestibular nerve that cause hearing loss, balance issues, and tinnitus.
Metastatic Brain Tumors: Secondary lesions that spread to the brain parenchyma from primary systemic cancers (such as lung, breast, or kidney cancers).
Key Surgical & Diagnostic Approaches
| Technique | Operational Goal | Primary Application |
| Microsurgical Resection | Maximum safe tumor removal while preserving intact brain tissue | High-grade gliomas, meningiomas, large tumors |
| Endoscopic & Keyhole Surgery | Direct access to deep or skull base tumors with minimal tissue disruption | Pituitary adenomas, anterior skull base lesions |
| Stereotactic Biopsy | Millimeter-precision tissue sampling for definitive histopathological and molecular profiling | Deep-seated or inoperable lesions |
| Neuronavigation & Functional Mapping | Real-time 3D tracking and cortical mapping to preserve speech and motor regions | Tumors located in or adjacent to eloquent brain areas |
