Lipoma of the corpus callosum is a rare intracranial lesion, perhaps congenital and often asymptomatic, but can present with seizure disorder, headache, mental changes, paresis or paralysis. Twenty-one patients had been operated upon. Surgical treatment seems to be of no value in this disease.
Can a brain lipoma grow?
Rarely, lipomas grow on the muscles, internal organs or brain. The majority of people with a lipoma only have one, although more than one lipoma can grow.
Can a lipoma cause seizures?
Epilepsy is the most common presentation of the Lipoma of the Corpus Callosum. It can reveal as a generalized seizures as for our patient but also as status epilepticus, partial motor or complex partial seizures.
What causes Pericallosal lipoma?
The pathogenesis of a pericallosal lipoma is considered to be the result of an abnormal persistence and differentiation of the meninx primitiva into lipomatous tissue 6. Typically resorption occurs between the 8th and the 10th week of gestation.
What is Pai syndrome?
Background: Pai syndrome (PS) is a rare regional developmental defect of the face, mainly characterized by the variable association of midline cleft of the upper lip (MCL), duplicated maxillary median frenulum, and midline facial cutaneous and midanterior alveolar process polyps.
Are lipomas in the brain common?
Intracranial lipomas are a well-known entity and are described as a rare finding with an incidence between 0.08 and 0.46% in autopsy series1.
Can lipoma cause death?
The autopsy revealed the presence of an undiagnosed massive brain lipoma (60 × 35 mm) associated with atrophy of the corpus callosum. Although very rare and seldom malignant these may be associated with seizures and sudden death.
Is a brain lipoma a tumor?
Intracranial lipomas are not tumors as such, but rather a result of abnormal differentiation of embryologic meninx primitiva. They are frequently associated with abnormal development of adjacent structures.
Is the corpus a callosum?
The corpus callosum (Latin for “tough body”), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental mammals….

What is Pericallosal artery?
The pericallosal artery is the distal portion of the anterior cerebral artery (ACA) that courses over the superior surface of the body of the corpus callosum in the pericallosal cistern. It gives off many small branches to the corpus callosum, forming the pericallosal moustache.
What is PAI-1 4G 5G?
The 4G/5G polymorphism is a common polymorphism in the promoter region of the PAI-1 gene. Both the 4G and 5G alleles have a binding site for an activator of transcription. The 5G allele, however, has an additional binding site for a repressor, resulting in lower transcription rates and less PAI-1 activity.
What does a large corpus callosum lipoma (CCL) mean?
Brain MRI revealed a large corpus callosum lipoma (CCL) and severe dysgenesis of the corpus callosum ( figure ). CCLs are not true neoplasms but congenital abnormalities, often found incidentally on imaging. A total of 50% of patients with CCL have epilepsy
How are intracranial lipomas diagnosed?
In older patients, intracranial lipomas are often found incidentally at autopsy. Radiographically, a lipoma of the corpus callosum is easily identified on plain skull films. Specifically, a radiolucent zone, which corresponds to the fatty tumor, is surrounded by curvilinear calcifications [2].
Where do lipomas usually appear in the brain?
Location: Lipomas most commonly appear in the corpus callosum. However, they can appear in other areas of the brain, usually close to the midline.
What is anticonvulsant therapy for lipomas?
Anticonvulsant therapy is the treatment modality of choice in symptomatic lipomas. Surgical management proves to be challenging due to the high vascularity and adherence of the lesion to the surrounding parenchyma and should only be pursued if the patient fails medical management [2,10].
