[Cerebellar infarction restricted to bilateral inferior vermis presenting with floating sensation and then astasia].

A 76-year-old man suddenly experienced floating sensation, transient vertigo, and nausea. Neurological examination was unremarkable except for hypotonia and mild ataxia in the limbs, but orthostatic nausea and vomiting forced him to take a quiet, recumbent position. Magnetic resonance imaging of the brain showed cerebellar infarction restricted to the bilateral inferior vermis. During a course of recovery, he fell down in any directions while standing unattended. He was unable to keep the center of gravity on the feet base in an upright posture. The inferior vermis may participate in maintaining the center of gravity while standing.

[Listeria monocytogenes meningoencephalitis lacking meningeal signs].

We report a fatal case of meningoencephalitis due to Listeria monocytogenes. A 74-year old alcoholic man presented with high-grade fever lasting for four days without headache and meningeal signs. Routine blood analysis showed leukocytosis, but serum C-reactive protein (CRP) was not significantly elevated. He developed altered consciousness with focal seizure, and cerebrospinal fluid (CSF) examination showed a minor degree of pleocytosis, elevated protein, and hypoglycorrhachia. Repeated CSF examination four days later showed greater increases in cells and proteins as well as severely decreased glucose level. Bacterial culture from the initial CSF showed a growth of L. monocytogenes. Meningoencephalitis caused by L. monocytogenes may have atypical clinical and laboratory features, and should be listed in the differential diagnosis of immunocompromised or elderly patients presenting with fever of unknown origin associated with altered consciousness.

Cheiro-pedal syndrome following pontine infarction.

We report the case of a 64-year-old man with sudden onset of numbness in the right hand and foot. Neurological examinations were normal except for hypersthesia, and hyperalgesia of the right hand and foot. Brain MRI demonstrated a high signal intensity on T2-weighted image and a low signal intensity on T1-weighted image in the left tegmetum of the pons. He was diagnosed with pontine infarction presenting with cheiro-pedal syndrome (CPS). Damage in the sensory pathways can cause CPS. Difference in the threshold may explain the specific sensory pattern in this syndrome. Further examination of the relationship between sensory symptoms and localization on MRI is needed to clarify this syndrome.
