Presentation
Motor vehicle collision. Evaluate for intracranial hemorrhage.
Patient Data
There is a hypodense cystic lesion in the pineal gland with a small focus of calcium anteriorly.
No evidence for acute intracranial abnormality. Ventricles are normal in size, shape and position. Mild cerebellar tonsillar ectopia is noted.
There are multiple T2 hyperintense cysts within the pineal gland with the largest lesion measuring up to 9 mm. There is no associated nodular or masslike enhancement. There is no evidence of a significant associated mass effect on the tectum.
Case Discussion
This is highly suspected case of a pineal cyst. This was an incidental finding on the initial CT. Given the size, an MRI was ordered which further suggested a pineal cyst. The patient was scheduled with neurosurgery who opted for nonsurgical observation.
