ation of the forehead lump. A large lobulated fat intensity nonenhancing mass was seen in the midline frontal region on T 1 and T 2 -weighted images ( fig. 2 , 3 ). The mass was hypointense on fat suppression T 2 and was seen intracranially in a dilated third and lateral ventricle, extending through the cribriform plate to become continuous with the subcutaneous fat through a large frontal bone...

Benign extramedullary tumours of the foramen magnum region are largely schwannomas and meningiomas. Tumours originating from the motor part of cranial nerves, such as the VIIth, IXth, XIth and XIIth cranial nerves, are extremely rare. Hypoglossal nerve (cranial nerve XII) schwannomas are such an example, usually arising intracranially and, in exceptional cases, extending into the extracranial c...

Intraand parasellar tumors are the most common intracranial neoplasms to harbor abscess because of direct extension of microbial flora from paranasal sinuses.1,2 Glioblastoma, astrocytoma (high and low grade), ependymoma, and metastatic lesions have also been reported to harbor abscesses within them. Only nine cases of intracranial meningioma associated with brain abscess have been reported in ...

The nasal glioma is a rare congenital nasal abnormality, which manifests as a mass of extracranial cerebral tissue unconnected with the brain. The clinical entity is challenging for several reasons. Their diagnosis may not be immediately obvious at presentation. It is important to exclude an intracranial extension, and for this some have suggested a craniotomy. We report a case of extranasal gl...

OBJECT Factors affecting the postoperative recurrence of chronic subdural hematomas (CSDHs) have not been sufficiently investigated. The authors have attempted to determine features of CSDHs that are associated with a high or low recurrence rate on the basis of the natural history of these lesions and their intracranial extension. METHODS One hundred six patients (82 men and 24 women) harbori...

Background Metastatic renal cell carcinoma (RCC) of the head and neck with intracranial extension is rare and may pose difficulties to the diagnosis and management. Method We describe a unique case of a 76-year-old man with a metastatic RCC to the neck and lateral skull base with intracranial extension presenting with Collet-Sicard syndrome 8 years after initial diagnosis. The radiologic featur...

OBJECTIVE To describe the use of the transglabellar subcranial approach for the management of congenital nasal masses in the pediatric population. METHODS Case series. Medical records of 5 patients who underwent resection of congenital nasal lesions via the subcranial approach were reviewed. RESULTS Five children underwent successful resection of congenital nasal lesions with intracranial e...
