A 44-year-old woman with prolonged coma and hypotension following drug overdosage developed bilateral hemorrhagic infarcts in the dorsolateral brainstem. The regional distribution of these paired lesions corresponds to the area of confluence of penetrating arteries in the brainstem. It is suggested that under exceptional circumstances brainstem arterial end-zones may be vulnerable to anoxic-isc...

A woman had anosognosia for hemiplegia as a manifestation of brainstem infarction. She had no mental or neuropsychological disturbances, and had involvement of the brainstem in the frontal/parietal-subcortical circuits to the right cerebral hemisphere. Brainstem lesions that disrupt frontal/parietal-subcortical areas may affect anosognosia for hemiplegia.

Summary A 3‐year‐old Thoroughbred mare found recumbent in the field was referred for further assessment with suspicion of a skull fracture. Neurological examination identified compulsive tight circling to left, and hypermetria all four limbs. The obtunded, mild head tilt right, absent menace response right eye decreased facial sensation on right. Standing computed tomographic revealed subtle de...

Cerebellar, brainstem and spinal cord metastases from esophageal cancer following radiotherapy are extremely rare. The current study presents the case of a 74-year-old male who was admitted to the Zhejiang Cancer Hospital (Hangzhou, China) with a poorly-differentiated neuroendocrine carcinoma of the esophagus. Following radiotherapy, multiple abnormal signals in the brainstem and spinal cord we...

Brainstem stroke syndromes are primarily determined by clinical criteria. There are few diagnostic procedures which are of benefit for the evaluation of brainstem ischemic events. Brainstem auditory evoked responses (BAERs) are a new electrophysiologic technique for assessing brainstem function. To evaluate the use of BAERs in patients with brainstem ischemic events, 35 individuals with recent ...
