Urinary retention, paresthesias, and fatigue. The spinal cord displays normal signal. There is central posterior disc-osteophyte complex at C5-6, which abuts the spinal cord. There is focal thickening of the ligamentum flavum at multiple levels of the lower thoracic spine, which mildly narrow the spinal canal, but do not impinge upon the spinal cord. The vertebral column alignment is within normal limits. There is no evidence of enhancing mass lesions in the cervical or thoracic spine. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. The paravertebral soft tissues are unremarkable. There is a nodule in the right thyroid lobe, which measures up to 18 mm. There is a retention cyst in the left maxillary sinus. The imaged intracranial structures are unremarkable.
1. No evidence of demyelinating lesions in the cervical and thoracic spinal cord.2. A central posterior disc-osteophyte complex at C5-6 abuts the spinal cord. 3. Focal thickening of the ligamentum flavum at multiple levels of the lower thoracic spine, which mildly narrow the spinal canal, but do not impinge upon the spinal cord. 4. Nonspecific nodule in the right thyroid lobe, which measures up to 18 mm. A thyroid ultrasound may be useful for further evaluation.
