MR appearance of interpeduncular lipoma.
Interpeduncular lipoma (IPL) is a very rare benign intracranial lesion. Non-invasive diagnosis of this condition is important, as these lesions are usually asymptomatic and are found incidentally. We describe a rare case of IPL in a 35-year-old woman presenting with headache of long duration and a recent increase in severity and frequency of headache. There was no neurological abnormality on clinical examination. MR imaging demonstrated a homogeneous lobulated T1-hyperintense and T2-hypointense lesion in interpeduncular fossa. A T1-weighted fat suppression sequence with chemical shift method confirmed the fatty nature of the lesion. The patient was managed conservatively.
