A 61-year-old woman in excellent health and taking no medications presented with progressive dyspnea on exertion. She did not exhibit diplopia, dysphagia, dysarthria or muscle weakness. Her condition deteriorated, and respiratory distress developed. The patient was intubated and placed on mechanical ventilation. A computed tomogram of her chest revealed a moderately enlarged thymus gland unsuspected on a plain x-ray film. Myasthenia gravis was diagnosed on the basis of a high acetylcholine receptor antibody titer. Treatment started with prednisolone, anticholinesterase agent, and plasma exchange. The patient underwent a thymectomy 3 weeks after her diagnosis. Her symptoms were brought under control by anticholinesterase agent and prednisolone. This case illustrates the need to consider myasthenia gravis as well as other motor-neuron disorders when evaluating individuals presenting acute respiratory failure of unknown origin.

A 71-year-old female, without medical or family history for cerebrovascular disease, presented with basilar and bilateral carotid dolichoectasia manifesting as dysarthria and hemisensory disturbance, which resolved spontaneously within a day. She suffered brainstem infarction 28 months later, manifesting as drowsiness, dysarthria, and right hemiparesis. Her consciousness level progressively deteriorated to stupor within 4 days. Computed tomography taken on the 5th day confirmed cerebellar infarct in the perfusion area of the superior cerebellar artery but did not show subarachnoid hemorrhage. She died of acute respiratory failure on the 7th day. Autopsy demonstrated a tear in the lateral wall of the broad-based aneurysm on the ectatic basilar artery and diffuse subarachnoid hemorrhage. Vertebrobasilar ectasia is a dynamic vasculopathy that may rapidly progress in the affected basilar artery following an indolent clinical course. The prognosis for patients with vertebrobasilar ectasia may depend mainly on the pathological changes in the basilar artery.

A case of brainstem encephalitis in a man positive for both anti-Hu and anti-Ri antibodies is reported. This case had an unusual double step evolution and progressive involvement of different CNS subdivisions at MRI. Brainstem encephalitis developed abruptly, mimicking a posterior vascular deficit with vertigo and dizziness. These symptoms transiently remitted completely after a few days to relapse acutely 1 month later with sudden loss of consciousness, followed by confusion, disorientation, dysarthria, dysphagia and reduced thermic sensation on the right side. Within another few days, the patient developed acute respiratory failure and died some weeks later. MRI was negative at the beginning but later showed a progressive ascending involvement of the brainstem and thalamus. At autopsy, this picture corresponded to lymphocytic infiltration, preferentially B cells into the perivascular spaces and T cells in the brainstem parenchyma, confirming that T cells could be the effector of cytotoxicity, probably in the presence of cooperation with B cells that were well represented in this setting.
