Isolated vertigo is generally attributed to labyrinthine disease, but may also signal otherwise asymptomatic cerebellar infarction. Of 309 subjects admitted between April 2004 and March 2009 for the single symptom of acute vertigo initially thought to be labyrinthine, four were found to have cerebellar infarction of the posterior inferior cerebellar artery area (PICA). All were over 60 years old and had risk factors including
hypertension
, diabetes mellitus, arrhythmia, and/or hyperlipidemia. Two had trunk ataxia, with magnetic resonance imaging (MRI) showing infarction within a few days. The other two could walk without apparent trunk ataxia, however, it took 4 to 7 days to find the infarction, mainly through neurological, neurootological, and MRI findings. Neurologically,
astasia
, dysbasia or trunk ataxia were important signs. Neurootologically, nystagmus and electronystagmographic testing involving eye tracking, saccade, and optokinetic patttens were useful.

Isolated cases of
astasia
or ptosis have each been reported in ischemic or hemorrhagic strokes involving the thalamus. We report a 70-year-old man with a medical history of
hypertension
who presented with left ptosis and gait disturbance despite intact motor strength in the legs and normal sensory function. MRI of the brain showed an evolving subacute infarction confined to the anteromedial-medial part of the left thalamus with no other areas of recent infarction identified. To our knowledge, combined ptosis and
astasia
in thalamic infarction has not been reported in the English literature. We identified 11 patients with thalamic ptosis and 21 with thalamic
astasia
in the literature. Patients who had ptosis, or gait abnormality which would not be related to thalamic stroke, were excluded; for example, evidence of infarction in the hypothalamus, midbrain, pons, cerebellum, or cingulate gyrus.

A 42-year-old young lady presented with acute onset of dizziness, drooping of left eye with binocular diplopia and inability to walk unassisted. She had past history of uncontrolled diabetes mellitus and
hypertension
. On examination, she had left fascicular type of third nerve palsy, vertical one and half syndrome (VOHS), left internuclear ophthalmoplegia and skew deviation with ipsilesional hypertropia. She also had thalamic
astasia
and right unilateral asterixis. Her MRI revealed T2 and Flair hyper intense signal changes with restricted diffusion in the left thalamus, subthalamus and left midbrain. MR Angiography was normal. Thalamic-subthalamic paramedian territory infarct is relatively uncommon. It can present with oculomotor abnormalities including vertical one and half syndrome, skew deviation, thalamic
astasia
and asterixis. This case is reported for the rarity of the presenting clinical findings in unilateral thalamo-mesencephalic infarcts.
