“…Interestingly, in our sample, only 50% of the lipomas were initially reported. The same discrepancy between quite a common occurrence and the disregard in the literature has been shown also for small intracranial lipomas on brain CTs [ 3 ].…”

SummaryBackgroundPancreatic lipomas are reported to be rare but their prevalence is unknown. This study examined the prevalence of pancreatic lipomas in a sample of patients undergoing abdominal computed tomography.Material/MethodsRetrospective review of 100 abdominal computed tomographic scans.ResultsIn 6 patients small pancreatic lipomas were found. There was no predominance in location or gender. The lipomas measured between 4 and 12 mm. All lipomas were incidental findings unrelated to patients’ symptoms.ConclusionsPancreatic lipomas seem to be quite a common finding and can be found in 6% of patients undergoing abdominal CT. Radiologists should be aware of this finding to establish proper differential diagnosis.

“…Intracranial lipomas are congenital lesions because of abnormal differentiation of embryological meninx primitiva (subarachnoid space precursor). These lesions are a rare finding with an incidence of 0.08% and 0.46% in autopsy series [3] . In a review of 3000 brain CT scans of head trauma patients, only 3 lipomas were reported in 0.1% of the scans [3] .…”

Intracranial lipomas are extremely rare fat-containing lesions that comprise 0.1%-0.5% of all primary brain tumors. They are congenital lesions that arise due to persistence and maldifferentiation of the meninx primitive (subarachnoid space precursor). We report a case of a 30-year-old woman who presented with seizures due to an intracranial lipoma and no neurological deficits. CT (computerized tomography) imaging findings demonstrated a large interhemispheric partially calcified lipoma that communicated with a large scalp lipoma and was associated with agenesis of the corpus callosum. Compared to the prior CT imaging, the lipoma increased in size from 3.4 cm to 4.1 cm transversely. A recent CT angiogram done due to suspicion of an aneurysm showed the lipoma now measuring 6 cm by 4.7 cm. Most cases of intracranial lipoma have been reported in the pediatric age group. Here, we report a rare case of interhemispheric intracranial lipoma in the adult age group. This case also demonstrates the importance of imaging modalities for detecting intracranial lipoma without performing invasive brain biopsy.

“…Most of the intracranial lipomas are asymptomatic and an incidental finding on brain imaging studies for other conditions, but some are associated with congenital malformations, headache, vertigo, and seizures depending on their location [1 , 4 , 5] . Our patient was presented with forehead scalp swelling that he had since birth and he wanted to remove the lesion with surgical intervention.…”

“…They are usually located in the midsagittal region of the brain mostly in the vicinity of the corpus callosum, quadrigeminal cistern, suprasellar cistern, cerebellopontine angle cistern, and Sylvian cistern [2 , 3] . Most of the intracranial lipomas are asymptomatic and incidental findings on brain imaging studies for other conditions, but some are associated with congenital brain malformations, headache, vertigo, and seizure depending on their location [1 , 4 , 5] . Both CT and MRI can be used for the diagnosis of intracranial lipoma.…”

Corpus callosal lipoma in a young adult with extracranial extension, presenting as a frontal scalp swelling: A rare case report

Intracranial lipomas are rare congenital lesions of the pediatric age group and incidental findings in neuroimaging studies, but some are associated with other congenital malformations. They are usually located in the interhemispheric fissure, often in the vicinity of the corpus callosum. Most of the intracranial lipomas are asymptomatic and require no therapy. The diagnosis is usually made based on the imaging findings and doesn't need histologic conformation. The author presents here the imaging findings of a corpus callosal lipoma with unusual extracranial extension in a 30-year-old male, highlighting the need for a complete evaluation of each patient presenting with a scalp lesion before any intervention, irrespective of the age group.
