Case Discussion
The patient had a history of lymphoma and now complaining new onset headache. No neurological deficit noticed during the clinical examination.
The quadrigeminal cistern lipoma is likely to be an incidental finding. It is important to mention that the lesion can be easily overlooked on the CT scan if there is no obvious mass effect and if the CT widowing is inappropriate.
