Optic perineuritis (OPN) is a rare form of orbital inflammatory disease of optic nerve sheath. The clinical presentation of OPN are known as distinct from demyelinating optic neuritis (ON). Recently, we have experienced a patient with bilateral idiopathic ON who had initial magnetic resonance imaging (MRI) feature of OPN. Serial MRI and funduscopic examination exhibited the bilateral ON findings. Serial MRI and funduscopic examination are needed in diagnosing OPN to differentiate to the temporal change of ON.

Carbon monoxide poisoning causes hypoxic brain damage with various neurological complications. Cerebral hemorrhagic infarction has rarely been reported as a complication of carbon monoxide poisoning. The author experienced a patient who developed cerebral infarction in the striatocapsular area extending to the corona radiata after carbon monoxide poisoning, which was followed by hemorrhagic transformation associated with neurological deterioration.

Sinking skin-flap syndrome is a rare complication of a skull defect after craniotomy. A 69-year-old woman visited our hospital and was diagnosed with a left middle cerebral artery infarction. Decompressive craniotomy was performed for cerebral herniation on the following day. However, on day 25 of hospitalization her mental status worsened and her scalp appeared sunken. This case suggests that sinking skin-flap syndrome can develop from a skull defect after decompressive craniotomy.

A 79-year-old woman experienced the sudden onset of cognitive impairment that interfered with her activities of daily living. A neurological examination revealed no focal neurological deficits. Brain magnetic resonance imaging showed an acute infarction in the left anterior corona radiata, and neuropsychological tests revealed attention deficit, verbal memory impairment, and frontal executive dysfunction. This case suggests that a focal infarction affecting the anterior portion of the corona radiata can cause a strategic infarct dementia that predominantly manifests as frontal lobe dysfunction.

Cryolipolysis has become available for the noninvasive reduction of adipose tissue. A 33-year-old woman presented with wrist drop of the right arm that had first appeared 7 days previously. She had undergone cryolipolysis on both upper arms immediately prior to the onset of symptoms. A nerve conduction study showed radial neuropathy proximal to the elbow, and ultrasonography revealed focal swelling of the radial nerve at the spiral groove. Although cryolipolysis has been known as a safe method, nerve injury can result from compression and/or hypothermia during the procedure.
