The transglabellar subcranial approach for nasal dermoids with intracranial extension.

Objectives/hypothesis: Nasal dermoids are the most common congenital midline nasal lesions. When a midline nasal pit or cyst is identified, scans should be obtained to look for an intracranial connection. The intracranial portion of the lesions has traditionally been approached by the performance of a frontal craniotomy.

Suprasellar hemangioblastoma in Von Hippel-Lindau disease: a case report.

Hemangioblastomas of the sellar and suprasellar regions are extremely rare lesions. We present a case of a suprasellar hemangioblastoma occurring in a 40-year-old female with Von Hippel-Lindau disease.

Magnetic resonance imaging characteristics of hyperacute hemorrhage in the brain and spine.

Five distinct stages have been defined for the magnetic resonance (MR) appearance of intraparenchymal hematomas in the brain: hyperacute, acute, early subacute, late subacute and chronic. Despite the extensive study of the evolution of hematomas there has been little attention given to the MR appearance of the posthemorrhagic state within the initial hours after the hemorrhage occurs. We discuss and illustrate the MR imaging characteristics of hyperacute hemorrhage.
