Watch out for the special location of intraventricular silicone oil following an intraocular tamponade - a 10-year follow-up case report based on CT/MRI.

Background: Intraventricular silicone oil is a relatively rare complication resulted from silicone oil tamponade to treat retinal detachment. It is occasionally reported in previous literature. To the best of our knowledge, the long-term longitudinal comparisons of silicone oil both in the brain and in the postoperative eyeball based on CT/MRI were lacking, and intraventricular silicone oil accumulation beside lesions has been reported rarely.

Choroid plexus papilloma presenting as an occipital mass with neck pain: Case report.

Rationale: Choroid plexus papillomas are rare benign central nervous system neoplasms arising from choroid plexus epithelium. They are most often located in the lateral ventricle, followed by the fourth and third ventricles and, rarely, in the cerebellopontine angle.

Patient Concerns: We report an uncommon case of a 17-year-old boy who presented with neck pain that had lasted for more than 1 month, with accompanying pain and numbness in his upper extremities.
