Which neurosurgical pathology would a myelogram be used to diagnose?

• A. Subdural hematoma
• B. Creutzfeldt-Jakob disease
• C. Spinal stenosis
• D. Myelomeningocele

Answer: (C)

A myelogram is a diagnostic imaging procedure that involves the injection of a contrast dye into the spinal canal, which allows for detailed visualization of the spinal cord, nerve roots, and surrounding structures through imaging techniques like X-ray or CT scans. This procedure is particularly useful for assessing structural abnormalities within the spinal canal. Spinal stenosis, a narrowing of the spinal canal that can lead to pressure on the spinal cord and nerves, is one of the conditions that can effectively be diagnosed using myelography. The procedure can reveal the specific areas of narrowing and help determine whether surgical intervention is necessary. For the other conditions listed, while they all involve the central nervous system, they do not require myelography for diagnosis. A subdural hematoma is typically diagnosed using CT or MRI imaging to detect bleeding between the brain and its outermost covering. Creutzfeldt-Jakob disease is diagnosed primarily through clinical evaluation and certain biomarkers, as imaging studies often show nonspecific findings. Myelomeningocele, a type of spina bifida, is usually diagnosed using ultrasound or prenatal imaging rather than myelography, as the defect involves both the spinal column and the surrounding tissues, and management may depend more on external examination than on the intric
