Intracranial lipomas—a clinical study

Intracranial lipoma in Quadrigeminal Cistern

“…Intracranial lipomas are more frequent in quadrigeminal region of brain, most are asymptomatic, and generally caught incidentally 4 . Intracranial lipomas are accepted congenital malformation stemming from abnormal differentiation of persistent menix primitive, an area that constitute the inner level of pia, arachnoid and dura mater 4 . Lipoma in the quadrigeminal regions has been reported as lipoma in quadrigeminal cistern, quadrigeminal plate, ambiens cistern or superior medullary velum 5 .…”

Intracranial Epidermoid Tumor After Subcutaneous Lipoma Excision -Case Report-

“…1,2,5,13) Intracranial lipoma is a rare lesion that accounts for 0.46-1% of intracranial tumors. 16) Only four cases of interhemispheric lipoma connected to subcutaneous lipoma via a bone defect in the anterior fontanel 2,5,13) and midline parietal bone 1) have been reported in infants. A previous case of cerebellopontine angle lipoma extending to the extracranial space involved a defect in the petrous ridge, 7) and a lipomatous stalk was identified between an interhemispheric lipoma and subcutaneous tissue in a 9-week-old boy.…”

Intracranial Lipoma: A Rare Variant of Brain Tumor

“…2,3 In CT, it typically appears as a mass with uniform hypodense fat density without enhancement. Some peripheral calcifi cation may be present, occasionally, as in our case.…”

“…1,2 This congenital aberration stems from abnormal differentiation of persistent menix primitive, an area that constitutes the inner level of pia, arachnoid and dura mater. 3 They can be found anywhere intracranially. The most common ones based on sites are 1 Pericallosal Lipoma (45%), Quardigeminal cistern lipoma (25%), Suprasellar cistern lipoma (15%), Cerebellopontine angle lipoma (10%), Sylvian fi ssure lipoma (5%).…”

“…On the basis of these radiological features the diagnosis of intracranial lipoma was made. 3 Patient was started on anti-epileptic drugs (AED) following which he is completely seizure-free. MRI brain repeated after few years of regular follow up revealed no increase in size of the mass Intracranial lipoma is a benign slow growing congenital lesion, which accounts for <0.1% of all primary brain tumors.…”
