Case Reports
Optic nerve sheath fenestration for the treatment of papilledema secondary to cerebral venous thrombosis.
A 16-year-old adolescent girl with multiple risk factors for thrombosis presented with acute onset of headache, decreased vision, and papilledema. Evaluation demonstrated cerebral venous thrombosis (CVT) involving the left transverse and sigmoid sinuses and left internal jugular vein. Following bilateral optic nerve sheath fenestration (ONSF), she experienced improvement in vision and resolution of papilledema. In selected cases, ONSF is an effective surgical option for the treatment of papilledema due to CVT after medical treatment has failed.

Review Case Reports
Primary spontaneous cerebrospinal fluid leaks and idiopathic intracranial hypertension.
Idiopathic intracranial hypertension (IIH) is increasingly recognized as a cause of spontaneous cerebrospinal fluid (CSF) leak in the otolarnygological and neurosurgical literature. The diagnosis of IIH in patients with spontaneous CSF leaks typically is made a few weeks after surgical repair of the leak when symptoms and signs of elevated intracranial pressure (ICP) appear. ⋯ CSF leak occasionally may keep IIH patients symptom-free; however, classic symptoms and signs of intracranial hypertension may develop after a CSF leak is repaired, exposing these patients to a high risk of recurrence of the leak unless an ICP-lowering intervention is performed.

Case Reports
Perineural optic nerve enhancement on magnetic resonance imaging in giant cell arteritis.
Giant cell arteritis (GCA) may cause visually devastating optic neuropathy. In atypical cases, diagnosis of optic neuropathy can be delayed. We present 2 such atypical cases and demonstrate that contrast-enhanced orbital magnetic resonance imaging may be a valuable tool in patient evaluation and aid in the diagnosis of GCA.
