Left cerebellar hemisphere lesion, spine survey due to symptoms, 6 month follow up: precocious puberty. Brain: There is a persistent patchy T2 hyperintense lesion in the left cerebellar hemisphere, now measuring up to approximately 10 x 12 mm, previously 9 x 12 mm. There is no associated enhancement. There is a right cerebellar hemisphere developmental venous anomaly. There is no evidence of intracranial hemorrhage or acute infarct. 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, and scalp soft tissues are grossly unremarkable. There is scattered paranasal sinus mucosal thickening, particularly in the right frontal sinus.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 no significant spinal canal stenosis. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
1. Persistent left cerebellar hemisphere lesion, which may represent a neoplasm.2. No evidence of Chiari malformation or spine lesions.3. Paranasal sinus inflammatory changes, particularly in the right frontal sinus.
