Stereotactic Brain Biopsy: Diagnostic Pathology Test
Stereotactic brain biopsy is a minimally invasive procedure used to obtain a sample of brain tissue for diagnostic purposes. This procedure is typically performed by neurosurgeons using stereotactic navigation techniques to precisely target the area of concern in the brain.
The biopsy sample is then analyzed by pathologists to determine the presence of abnormal cells, such as those found in brain tumors like gliomas or in neurodegenerative conditions like Alzheimer's disease.
Examples of when a stereotactic brain biopsy may be necessary include when a brain lesion is detected on imaging studies, but its nature cannot be definitively determined without a tissue sample.
This procedure allows for a more accurate diagnosis and helps guide treatment decisions.
Stereotactic brain biopsy is a valuable tool in neurosurgery, as it allows for precise brain sampling without the need for more invasive open surgery. This minimally invasive approach reduces the risk of complications and shortens recovery time for patients.
What is the Purpose of Performing a Stereotactic Brain Biopsy Test?
The primary purpose of performing a stereotactic brain biopsy is to obtain a tissue sample for accurate diagnosis of brain tumors, such as gliomas, or other neurological disorders like Alzheimer's disease.
By analyzing the brain tissue obtained through the biopsy, pathologists can provide valuable information about the type of tumor present, its grade, and other important characteristics that help guide treatment decisions.
In cases of suspected brain lesions or neurological disorders, a stereotactic brain biopsy can provide definitive diagnostic information that may not be attainable through imaging studies alone.
The benefits of a stereotactic brain biopsy include a more precise diagnosis, which can lead to more targeted and effective treatment options. This procedure also helps reduce the need for more invasive surgeries and their associated risks.
What are the Costs of Stereotactic Brain Biopsy Tests in India?
The cost of a stereotactic brain biopsy in India can vary depending on several factors, including the hospital or clinic where the procedure is performed, the expertise of the medical team, and any additional tests or services required.
On average, the cost of a stereotactic brain biopsy in India ranges from INR 50,000 to INR 2,00,000. However, this cost may increase if additional imaging studies or consultations are needed.
- Factors that can influence the cost of a stereotactic brain biopsy in India include:
- The location of the hospital or clinic
- The experience and reputation of the medical team
- The complexity of the procedure
- Any additional tests or services required
It is essential for patients to discuss the cost of the procedure with their healthcare provider and insurance company to understand their financial responsibilities and explore any potential financial assistance options.
What is the Normal Range and All Values of Stereotactic Brain Biopsy?
The normal range for stereotactic brain biopsy results can vary depending on the specific test being performed and the laboratory conducting the analysis.
However, in general, normal values indicate the absence of abnormal cells or markers in the brain tissue sample.

Frequently Asked Questions
What is the purpose of a stereotactic brain biopsy?
What Do High Stereotactic Brain Biopsy Levels Indicate?
High stereotactic brain biopsy levels can indicate the presence of abnormal cells or markers in the brain tissue sample.
What Do Low Stereotactic Brain Biopsy Levels Indicate?
Low stereotactic brain biopsy levels typically indicate the absence of abnormal cells or markers in the brain tissue sample. This may suggest that the brain lesion or neurological disorder being evaluated is not present or is in an early stage.
How is a stereotactic brain biopsy performed?
During a stereotactic brain biopsy, a neurosurgeon uses imaging techniques to precisely guide a needle to the area of concern in the brain to collect a tissue sample for examination.
What conditions are diagnosed using stereotactic brain biopsy?
Stereotactic brain biopsy is used to diagnose brain tumors, infections, inflammation, and certain neurological conditions.
How accurate is the stereotactic brain biopsy in diagnosing brain tumors?
Stereotactic brain biopsy is a highly accurate procedure for diagnosing brain tumors, with a success rate of over 90% in obtaining a tissue sample for analysis.
What are the risks of a stereotactic brain biopsy?
The risks of a stereotactic brain biopsy include bleeding, infection, seizures, and neurological deficits. Your healthcare provider will discuss these risks with you before the procedure.
How long does it take to recover from a stereotactic brain biopsy?
Recovery from a stereotactic brain biopsy typically takes a few days to a week. Your healthcare team will guide you on post-operative care and when you can resume normal activities.
What kind of anesthesia is used during the procedure?
During the procedure, you will likely receive general anesthesia, which will make you unconscious and pain-free.
How are the biopsy results used to guide treatment?
Biopsy results help doctors determine the type of cancer present and its characteristics, which guides the most effective treatment plan for the patient.
Are there alternatives to stereotactic brain biopsy?
Yes, other options include open brain biopsy and needle biopsy. These procedures may be used based on the location and characteristics of the brain abnormality.
What imaging techniques are used to guide the biopsy procedure?
Imaging techniques like ultrasound, MRI, or CT scans are commonly used to guide the biopsy procedure and help the doctor locate the precise area for sampling tissue.
