Abstract

A 37-year-old rural lady with an intracranial lipoma of the quadrigeminal region with persistent headache is reported. We describe findings of imaging studies such as CT and MRI with review of literature. Diagnosis of Quadrigeminal Cistern Lipoma is always certain on imaging, and therefore histopathological confirmation is never practically required. However from a theoretical point of view, there are many other lesions which can present in this cistern on imaging.

Highlights

  • Intracranial lipoma are slowly growing benign congenital lesion accounting for 0.1-0.5% of all primary brain tumors and are usually detected as incidental findings at any age when the brain is imaged for other reasons

  • We report the case of a lipoma in the quadrigeminal cistern in a 37 year-old female presenting with headache

  • Intracranial lipomas are widely distributed in the intracranial compartment and they can be found essentially anywhere, certain regions are characteristic:

Summary

Introduction

Intracranial lipoma are slowly growing benign congenital lesion accounting for 0.1-0.5% of all primary brain tumors and are usually detected as incidental findings at any age when the brain is imaged for other reasons. 1 Most lipomas were incidentally detected by autopsy or computed tomography. Intracranial lipoma are slowly growing benign congenital lesion accounting for 0.1-0.5% of all primary brain tumors and are usually detected as incidental findings at any age when the brain is imaged for other reasons. Most lipomas were incidentally detected by autopsy or computed tomography. Most intracranial lipomas are found incidentally during neuroradiological investigation with CT & MRI examination. The incidence on CT findings in no more than 0.03 to 0.06% and autopsy incidence is 0.08 to 0.46%. These slowly growing benign lesions rarely require surgery 3
