Left sided weakness. Brain: There appears to a small, faintly enhancing lesion with susceptibility effect in the right amygdala. There is concavity of the superior aspect of the pituitary gland. There is approximately 5 mm of inferior cerebellar tonsillar ectopia. There is an ossified extra-axial nodule along the right superior frontal gyrus that measures 5 mm in diameter, which is better depicted on the prior head CT. There is no evidence of acute infarct. The cerebellum and brainstem appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.Cervical Spine: The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is a slight posterior disc-osteophyte complex at C5-6, but no significant spinal canal or neural foramen stenosis throughout the cervical spine. The spinal cord displays normal signal and morphology. There is no evidence of enhancing tumors in the cervical spine. The paravertebral soft tissues are unremarkable.
1. An apparent small, faintly enhancing lesion with susceptibility effect in the right amygdala is nonspecific, but may represent a neoplasm, sequela of prior infection or inflammation, such as a granuloma, or vascular malformation, such as a telangiectasia. 2. No evidence of acute cerebral infarction. 3. Mild inferior cerebellar tonsillar ectopia.4. Nonspecific flattening of the pituitary gland, which can represent atrophy of pseudotumor cerebri.5. An ossified extra-axial nodule along the right superior frontal gyrus that measures 5 mm in diameter may represent a meningioma or dural ossification, for example, but is better delineated on the prior head CT. 6. No significant spinal canal or neural foramen stenosis throughout the cervical spine.
