Spinal ependymoma diagnosis
see also Intracranial ependymoma diagnosis.
The diagnosis of spinal ependymoma typically involves a combination of medical history, physical examination, and imaging tests. During a medical history, the doctor will ask the patient about their symptoms, including any pain, weakness, or changes in sensation. A physical exam will involve assessing the patient's motor function, reflexes, and sensitivity to touch.
Imaging tests such as magnetic resonance imaging (MRI) and computed tomography (CT) scans are typically used to diagnose spinal ependymomas. An MRI can provide detailed images of the spinal cord and surrounding tissues, allowing doctors to identify any abnormal growths or tumors. A CT scan uses X-rays to produce cross-sectional images of the body, which can also help identify any abnormal growths.

Plain film features that may be seen with a spinal ependymoma include:
scoliosis
spinal canal widening
vertebral body scalloping
pedicle erosion
laminar thinning
CT
CT may demonstrate:
non-specific canal widening
iso to slightly hyper-attenuating compared with normal spinal cord
intense enhancement with iodinated contrast
large lesions may cause scalloping of the posterior vertebral bodies and neural exit foraminal enlargement
