Sturge-Weber syndrome accompanied with multiple congenital intracranial lesions.

Abstract: Sturge-Weber syndrome is one of the neurocutaneous syndromes. It is a rare, nonfamiliar disease that is characterized by facial port-wine stain, leptomeningeal angiomatosis, choroidal angioma, buphthalmos, intracranial calcification, cerebral atrophy, mental retardation, glaucoma, seizures and hemiparesis. CT and MR are complementary in the evaluation of this disease. Epilepsy is an essential feature of Sturge-Weber syndrome and it has a major significance for prognosis and treatment. We report a 2-year-old boy with Sturge-Weber syndrome who had in addition an intracranial lipoma, a temporal arachnoid cyst and a porencephalic cyst. This combination of intracranial lesions with Sturge-Weber syndrome has not been previously reported.

Intracranial lipomas: a retrospective study.

Abstract: Between 1996 and 2006, 17 patients with intracranial lipomas underwent MR imaging examination. Of these, two patients also had CT examination. Lipoma is not a typical tumor and could instead be called intracranial lipoma hamartoma or cerebral malformation. The predominant localization of the lipomas was close to midline structures, such as the area around the corpus callosum, quadrigeminal cisterns, etc. Interpreting the MRI it is necessary to differentiate epidermoid, dermoid and hemorrhage in the metahemoglobin stage from lipoma. Clinically, 47% of patients complained of headache, two presented with epileptic seizures and the remainder had different symptoms. The lipoma was just an incidental finding not related to the clinical symptomatology.

Intracranial and subcutaneous lipoma associated with sagittal sinus fenestration and falcine sinus.

Abstract: Intracranial lipomas are rare lesions. Intracranial lipoma associated with a subcutaneous lipoma is extremely rare. Various vascular abnormalities have been described in association with intracranial lipoma, including distension, kinking, or narrowing of arteries and veins; arteriovenous malformation; and aneurysm. To our knowledge, association of sagittal sinus fenestration, falcine sinus, and absent straight sinus with intraextracranial lipoma has not been reported before. We report the imaging findings of an infant with interhemispheric and subcutaneous lipoma associated with falcine sinus and sagittal sinus fenestration.

Giant intracranial lipoma.

Abstract: Intracranial lipomas are rare and usually benign in their course. We report a case of a giant intracranial lipoma presenting with raised intracranial pressure. Additionally, this patient was found to have a large lipoma of the anterior fontanelle. The clinical course and outcome of this patient is presented and relevant literature reviewed.

Intracranial Lipoma: A Rare Congenital Malformation

Abstract: Introduction Intracranial lipomas are uncommon benign lesions mainly occurring in the region of the corpus callosum [1]. Only approx. 0.1% of intracranial tumors are lipomas [2], however, advances in neuroimaging techniques have increased the likelihood of their detection during life [3]. Detection of intracranial lipomas is relevant because of their frequent association with other brain malformations. Sometimes patients suffer from neurological deficits or surgical treatment is necessary due to the size of the tumor. Case Report A 60-year-old man was admitted to the hospital due to craniocerebral trauma after sudden fall. A hemiparesis ensued, followed by reduction of vigilance and respiratory insufficiency. This prompted to endotracheal intubation and to the performance of a cerebral CT, which showed a small temporoparietal fracture and, adjacent to it, a narrow epidural hematoma without compressive effect. Additionally, a curvilinear hypodense zone was detectable in the left cisterna ambiens. Initially, air in the cisterna ambiens due to a small fracture of the skull base was postulated. Nevertheless, the density was approx. – 41 HE indicating fatty tissue (Figures 1a and 1b). However, the small size of the hypodense zone did not allow the accurate determination of the inner density. No expansive effect was visible. Therefore, to clarify the origin of the hemiparesis, e.g., whether a stroke had caused the sudden fall, a cerebral MRI was performed. The images showed an acute ischemic area at the crus posterior of the capsula interna, with signal increase in the diffusion-weighted images (DWI) and signal reduction at the apparent diffusion coefficient (ADC). The presence of the epidural hematoma was confirmed, with additional detection of a “contre coup” lesion in the contralateral parietal region.

Nonmidline intracranial lipoma misdiagnosed as meningioma: case report.

Abstract: A patient was initially believed to have a cavernous sinus and sphenoid ridge meningioma and presented to the University of Connecticut Health Center for radiation therapy. Initial radiation planning computerized tomography (CT) revealed the mass to be a lipoma. Conservative management with serial monitoring was the revised plan. This paper describes the rare entity of an intracranial lipoma not located in the midline, and some pitfalls in imaging of intracranial masses.
