BACKGROUND AND PURPOSE Negative findings on diffusion-weighted imaging (DWI) does not exclude the possibility of brainstem infarction, particularly in the acute stage of medullary lesion. Our aim was to investigate the false-negative rate of DWI in patients with acute lateral medullary infarction. METHODS We applied DWI to 26 patients with a clinical diagnosis of lateral medullary infarction ...

In rare cases restricted sensory deficits along the somatotopic topography of the spinothalamic tract can develop from a lateral medullary infarction. To our knowledge, isolated dermatomal sensory deficit as a single manifestation of a lateral medullary infarction has not been reported previously. A 58-year-old man presenting with sudden left-sided paresthesia complained of sensory deficit of p...

We present a clinical classification of central vestibular syndromes according to the three major planes of action of the vestibulo-ocular reflex: yaw, roll, and pitch. The plane-specific syndromes are determined by ocular motor, postural, and perceptual signs. Yaw plane signs are horizontal nystagmus, past pointing, rotational and lateral body falls, deviation of perceived straight-ahead to th...

PURPOSE To report a rare case of painful trigeminal neuropathy after lateral medullary infarct and probe its underlying pathogenesis on the basis of neuroimaging and electrophysiological study. CASE REPORT A 45-year-old man presented acute onset of unsteady gait followed by paroxysmal and electric shock-like headache in the distribution of ophthalmic branch of left trigeminal nerve in 2 days....

BACKGROUND Secondary cervical dystonia is induced by organic brain lesions involving the basal ganglia, thalamus, cerebellum, and brain stem. It is extremely rare to see cervical dystonia induced by a medullary lesion. CASE PRESENTATION We report a case of an 86-year-old Japanese woman who developed cervical dystonia following lateral medullary infarction. She developed sudden-onset left uppe...

OBJECTIVE The aim of this study was to determine saccular dysfunction by measuring cervical vestibular-evoked myogenic potentials (cVEMP) and to correlate abnormality of cVEMP with results of other vestibular function tests in lateral medullary infarction (LMI). METHODS We recorded cVEMP in 21 patients with LMI documented on MRI. cVEMP was induced by a short tone burst and was recorded in con...

Familial follicular cell-derived well-differentiated thyroid cancer, papillary (PTC), and follicular thyroid carcinomas (FTC), accounts for 95% of thyroid malignancies. The majority of are sporadic, and at least 5% of these patients will have familial disease. Familial thyroid syndromes are classified into familial medullary thyroid carcinoma (FMTC), derived from calcitonin-producing C cells, a...

Palatopharyngeal paresis has never been reported to be contralateral in the lateral medullary infarction (LMI). A 65-year-old lady with acute dorsolateral infarction in the left medulla presented mild hoarseness, mild dysphagia, mild gait ataxia along with marked hypalgesia and thermal anesthesia on the right limbs. To our surprise, palatal weakness was on the right side, instead of being on th...

Intertrochanteric fractures can be fixed with various implants surface or intramedullary implants. A study was done on Fixation of trochanteric Hip Nail/Intra Medullary Screw an innovative cephalomedullary nail designed by author to determine its efficacy, union operative use and functional outcome. Trochanteric hip were classified upon number parts, stable unstable in initial 43 cases. All as ...
