Presentation

Patient with headaches and hyperprolactinemia.

Patient Data

Age: 45 years

MRI

The MR sequences show a small well-defined lesion located in right para-median region of the quadrigeminal cistern. It appears of high intensity on both T1 and T2 with loss of signal on sagittal T1 fat saturation and blooming on the gradient echo sequence.

Case Discussion

The gradient echo and fat-saturated sequences are best sequences to differentiate lipoma from subarachnoid haemorhage.

The differential diagnosis should include also the lesions containig fat (see related article: intracranial lipoma).
