Parietal Lipomeningocele-Case Report-

Abstract

Fig. 1 Photograph of the tumor at the initial presentation. The tumor was located in the parietal region and had a soft and elastic consistency. The surface of the tumor was hairless. Abstract A 2-month-old female infant had had a parietal mass since birth. Neuroimaging revealed a lipoma under the splenium of the corpus callosum that was connected to the subcutaneous lipoma via a bone defect in the cranium bifidum of the parietal region. At the age of 5 months, partial resection of only the extracranial mass was carried out. The histological diagnosis was lipoma. She grew up normally without neurological disorders during follow up for 12 years after the surgery. In the present case, the intracranial lipoma was associated with the cranium bifidum, and dysraphism was possibly involved in the pathogenesis. Resection of only the extracranial subcutaneous tumor can be performed for cosmetic reasons.

Intracranial lipoma associated with a subcutaneous lipoma

“…Interhemispheric lipoma associated with a subcutaneous lipoma as in our patient is however extremely rare 8 . In these cases, the intra and extracranial masses may have no connection with each other, may be connected by a fibrous lipomatous stalk or may be continuous with each other through cranium bifidum 6,15,16,17 .…”

Frontal subcutaneous lipoma associated with interhemispheric lipoma, lipomeningocele, and corpus callosal dysgenesis in a young adult: CT and MRI findings

“…Different communication patterns are observed between intracranial and extracranial components of the lipoma ranging from no connection,[ 6 ] fibrous-lipomatous stalk[ 7 8 ] to direct continuity through cranium bifidum. [ 9 ] The explanation for direct extension through cranium bifidum is explained by Truwit and Barkovich[ 2 ] as secondary dehiscence of the cranium with potential evagination of a small tuft of meninx primitiva.…”

Intracranial and Subcutaneous Lipoma Associated with Sagittal Sinus Fenestration and Falcine Sinus

“…Different communication patterns can be observed between intracranial and extracranial components of the lipoma. They may have no connection, 6 may connect to each other by fibrous-lipomatous stalk, 7,8 or may have direct continuity with each other through cranium bifidum. 9 There is difficulty in the explanation of extracranial extension of the intracranial lipoma via cranium bifidum.…”
