Small lytic focus containing CSF intensity material involving the posterior aspect of the clivus. A small focus of CSF signal material protrudes posteriorly to the dorsal cortex of the clivus to abut the basilar artery. The lesion is just left of midline, has corticated margins on prior CT, and on previous contrast enhanced MR has never enhanced. No soft tissue component was seen. The surrounding clivus bone marrow is normal. No other abnormalities within the prepontine cistern and cerebellopontine angles.
A few hyper T2 and FLAIR signal abnormalities scattered through the supratentorial white matter are nonspecific, likely representing chronic small vessel ischaemia, in a number distribution usually seen the patient's age group. Brain parenchyma is otherwise unremarkable.
Well-defined rounded and high T2 signal lesion within the mucosa of the nasopharynx in keeping with a Thornwaldt cyst.
