TL;DR: This is the first report demonstrating that steroids may induce hypertrophy of the fat tissue in the intracranial lipoma, causing compression of the cranial nerves passing through the cavernous sinus thereby mimicking the ocular symptoms sometimes associated with aggressive giant cell arteritis.
Abstract: Intracranial lipoma is a rare condition, and it is usually asymptomatic. We describe a 67 year old woman who developed blurred vision, diplopia, left sided oculomotor palsy, and ipsilateral ptosis during steroid treatment for giant cell arteritis. These symptoms were considered to be associated with aggressive giant cell arteritis, and the steroid dose was raised. Surprisingly, the symptoms increased, and further examination revealed an intracranial lipoma situated in the Meckel's cave. During tapering of the steroids her symptoms gradually improved. This is the first report demonstrating that steroids may induce hypertrophy of the fat tissue in the intracranial lipoma, causing compression of the cranial nerves passing through the cavernous sinus thereby mimicking the ocular symptoms sometimes associated with aggressive giant cell arteritis.

TL;DR: Considering significant morbidity during resection, conservative follow-up is the best approach for CPA and IAC lipoma.
Abstract: Intracranial lipoma is an uncommon entity. A rare type of tumor in the internal auditory canal (IAC) and the cerebellopontine angle (CPA) is lipoma. There are a few case reports in the literature related to intravestibular lipoma. Herein, we report a case of lipomas within the cerebellopontine angle and vestibule of the inner ear in a patient with tinnitus and dizziness. The patient was evaluated with a 1.5 T magnetic resonance imaging (MRI) system. MRI and CT showed the masses in the left CPA and the left IAC. These lesions were hyperintense on both T1- and T2 weighted images and showed no enhancement after gadolinium administration. Conservative management was suggested. Histopathological diagnosis is rarely necessary with the widespread use of magnetic resonance imaging. Considering significant morbidity during resection, conservative follow-up is the best approach for CPA and IAC lipoma.

TL;DR: A child with lipoma of the corpus callosum with extracranial extension with no neurologic deficit submitted to resection of the extracanial extension is reported.
Abstract: Intracranial lipoma are usually localized in the corpus callosum and rarely extends to the subgaleal region. Only eight cases of lipoma of the corpus callosum with extracranial extension were reported in the literature. Seizures and mental retardation were the most common clinical findings in these patients. Data from the literature show that resection of intracranial lipoma has catastrophic results. The resection must be restricted to the extracranial portion. We report a child with lipoma of the corpus callosum with extracranial extension with no neurologic deficit submitted to resection of the extracranial extension.

TL;DR: This is the only case of intracranial lipoma located in the interpeduncular fossa of a young woman which was demonstrated by magnetic resonance images (MRI) in the English language literature.
Abstract: A case of intracranial lipoma located in the interpeduncular fossa of a young woman is presented. Since the patient suffers only nonspecific headache, no treatment was performed. To our knowledge this is the only which was demonstrated by magnetic resonance images (MRI) in the English language literature.
