History of concussion now with abnormal olfactory sensation, bifrontal headaches, and vision abnormalities. No lesions are identified in the anterior skull base or anterior frontal lobes to suggest an etiology for the patient's symptoms. No suspicious intracranial mass or evidence of mass effect. No suspicious lesions on the postcontrast images. Incidentally noted is a left temporal-occipital developmental venous anomaly. There is a 13 mm pineal gland cyst without solid or enhancing components. No significant associated mass effect. There is no evidence of intracranial hemorrhage or edema. The ventricles and basal cisterns are normal in size and configuration. The expected intracranial vascular flow voids are present.Minimal mucosal thickening is present in the right anterior ethmoid air cells. There is a small left maxillary mucus retention cyst. Paranasal sinuses are otherwise clear. Calvarium and extracranial soft tissues are within normal limits.
There is a 13 mm pineal cyst with a benign appearance and likely an incidental finding. MRI of the brain is otherwise unremarkable.
