Background:A single inflammatory demyelinating brain lesion sometimes mimics a brain tumor on conventional magnetic resonance imaging (MRI), and thus poses a considerable diagnostic challenge. We assessed the usefulness of a new MRI technique, fast imaging employing steady-state acquisition (FIESTA), for the diagnosis of inflammatory demyelinating disease (IDD).

Management of concomitant metabolic encephalopathy and meningioma with vasogenic edema and impending herniation

Background:Altered mental status describes impaired mental functioning ranging from confusion to coma and indicates an illness, either metabolic or structural in nature. Metabolic causes include hypothyroidism, hyperuremia, hypo/hyperglycemia, hypo/hypernatremia, and encephalopathy. The structural causes include tumors, brain hemorrhage, infection, and stroke. To our knowledge, this is the first case in which a patient presented with altered mental status from both metabolic (myxedema coma) and structural diseases (frontal meningioma) with vasogenic edema and midline shift.

Chronic subdural hematoma of the posterior fossa treated by suboccipital craniotomy

Yuichi Mochizuki, Tomonori Kobayashi, Akitsugu Kawashima, Takayuki Funatsu, Takakazu Kawamata

Date of publication: 05-Feb-2018

Background:Chronic subdural hematoma (CSDH) of the posterior fossa is uncommon in adults. Only a few cases have been reported, and most of these were secondary to head injury or anticoagulant therapy. We herein describe a case of successful surgical treatment of CSDH in the posterior fossa after surgical removal of a large supratentorial and infratentorial dermoid cyst.

Benefits of spinal meningioma resection

Romel Corecha Santos, Ricardo de Amoreira Gepp

Background:Spinal meningiomas account for approximately 40% of intradural extramedullary tumors. As they are usually slow growing, some patients are often diagnosed late in the clinical course when they have developed myelopathy.
