A 32-year-old man presented with a history of intermittent headaches. On eExamination
revealed normal, visual acuity was normal and no neurological deficit was seen. Magnetic
Brain magnetic resonance imaging (MRI) brain scan was performed for further evaluation
and revealed a well-defined, curvilinear T1- and T2- hyperintense lesion (measuring 1.2 × 0.4cm) in the superior half of the cerebellar vermis. It that appeared hypointense on T1 fatsaturated images, (suggestive of fat content) in the superior half of the cerebellar vermis(Ffigure 1). No There was no evidence of any mass effect or hydrocephalus was seen. Thesefindings were suggestive of vermian lipoma. Superior vermian hypoplasia was also detected,; but however, the corpus callosum was appeared normal. No other abnormality was observedon MRINo other abnormality was seen on the MRI brain scan. Intracranial lipomas represent
a are congenital malformations resulting from with the abnormal differentiation of themeninx primitiva. In most cases, as in our case, Most intracranial lipomas are foundincidentally detected, as was the case in our patient. In sSymptomatic casespatients
commonly complain of , headache and psychomotor retardation are common complaints.
Seizures reported in cases patients with of intracranial lipomas appear secondary to theassociated anomalies. The pericallosal region, as well as the quadrigeminal cistern, andsuprasellar cisterns is are the common locations for intracranial lipomas. Vermian lipomas
are rare, with only a few reported cases in the literature containing only a few such cases. The
morphological variants of intracranial lipomas are the tubulonodular and curvilinear varieties.
Intracranial lipomas reveal homogeneous fat density (−-60 to −-120 HU) on plain CT
computed tomography scan and may contain calcific foci within, especially particularly in thetubulonodular variety. Intracranial lipomas display T1- and T2- hyperintense signals with
suppression on fat-saturated images. The associated anomalies, including dysgenesis of thecorpus callosum and vascular anomalies such as aneurysms, are better demonstrated
onrevealed by MRI and include dysgenesis of the corpus callosum and vascular anomalies
