Adrenal Gland Biopsy: What Patients Should Know About the Procedure, Results, and Recovery

An adrenal gland biopsy is a medical procedure in which a doctor removes a small sample of tissue from one of your adrenal glands, the small hormone-producing glands that sit on top of each kidney. The sample is examined under a microscope to help determine whether a lump or growth in the gland is benign or cancerous and to guide the most appropriate treatment plan for you.

An adrenal gland biopsy is a diagnostic procedure where a small sample of tissue is removed from the adrenal gland for pathological examination. The adrenal glands are small triangular-shaped glands located on top of each kidney. They produce hormones that regulate metabolism, stress response, and blood pressure. This biopsy helps doctors examine the cellular structure of the adrenal gland to identify abnormalities such as tumors, cysts, or other pathological conditions.

The procedure is usually performed with imaging guidance, such as a CT scan or ultrasound, which helps the doctor place a thin, hollow needle precisely into the adrenal gland. You will receive local anesthesia to numb the area, and in some cases mild sedation to help you stay comfortable and relaxed. Once the needle is in position, several small tissue samples are collected, and the entire process typically takes between thirty and sixty minutes.

The biopsy is typically performed by inserting a thin needle through the skin and into the adrenal gland. The procedure is usually guided by imaging techniques such as computed tomography (CT) or ultrasound to ensure accurate placement. Local anesthesia is used to minimize discomfort. The tissue sample is then sent to a pathology laboratory where it is examined under a microscope by a pathologist who specializes in diagnosing diseases through tissue analysis.

A pathologist, a physician specially trained to examine tissue, studies your sample under a microscope and prepares a pathology report. The report describes the type of cells found, whether the growth is benign or malignant, and other important features such as cell appearance and growth patterns. These findings help your care team confirm or rule out a diagnosis and decide on the most suitable treatment options for your specific condition.

The pathology report provides detailed information about the tissue sample, including: the type of cells present (cortical or medullary), whether the cells appear normal or abnormal, the characteristics of any identified mass (such as tumor type, size, and grade), whether the tissue is benign (non-cancerous) or malignant (cancerous), and whether there are any signs of infection or inflammation. This information is crucial for determining an accurate diagnosis and developing an appropriate treatment plan.

After the biopsy, you will be monitored for a few hours while your blood pressure, heart rate, and breathing are checked. Mild soreness or bruising at the needle site is common and usually improves within a few days. Most patients go home the same day, although you will need someone to drive you. Avoid heavy lifting and strenuous activity for about twenty-four to forty-eight hours, and contact your doctor promptly if you develop fever, severe pain, dizziness, or bleeding at the site.

After the biopsy, you may experience some soreness or bruising at the needle insertion site. Most patients can resume normal activities within 24-48 hours. Your doctor will discuss the biopsy results with you during a follow-up appointment, usually within one to two weeks after the procedure. The results will help determine whether additional treatment or monitoring is necessary.
