[A 49-year-old man with progressive dysarthria, dysphagia, and left hemiparesis].

We report a 49-year-old man who presented progressive dysarthria, dysphagia, and left hemiparesis. The patient was well until June 28th of 1993 when he noted 'weakness' in his both legs; despite his weakness, he could play golf on that day. In the beginning of July, he noted difficulty in swallowing solid foods. He was admitted to the neurosurgery service of our hospital on July 15th of 1993 and a neurologic consultation was asked on July 17th. Neurologic examination at that time revealed an alert but somewhat childish man who appeared to have some difficulty in paying attention to questions. He was disoriented to time and showed difficulty in recent memory and calculation. Higher cerebral functions were intact. The optic fundi were normal; pupils were isocoric and reacted to light promptly; ocular movements were intact, however, he showed difficulty in convergence. Facial sensation and facial muscles were intact. He had no deafness. He showed slurred speech and difficulty in swallowing solid foods. The remaining cranial nerves were intact. Motor-wise, he was able to walk normally and no weakness or atrophy was noted. Mild ataxia was noted in the finger-to-nose and the heel-to-knee test on the left. Muscle stretch reflexes were normal and symmetric, however, the plantar response was extensor bilaterally. Sensation was intact and no meningeal signs were noted. General routine laboratory findings were unremarkable. CSF was under a normal pressure containing 1 cell/microliter, 68 mg/dl of protein, and 54 mg/dl of glucose. Cranial CT scan showed low density areas involving the pons, midbrain, left thalamus, and the left parietal cortex. In MRI, these areas presented low signal intensity in T1-weighted images and high signal intensity in T2-weighted in images. The brain stem appeared swollen. Gadolinium enhancement was negative. He was given a course of steroid pulse with 1 g/day of DIV methylprednisolone for three days followed by oral steroid. He showed only temporary improvement in swallowing. In the subsequent course, he showed progressive deterioration in dysarthria and dysphagia. A biopsy was performed on the left parietal lobe lesion. After biopsy, he was treated with steroid and glycerol without improvement. A course of chemotherapy with procarbazine, MCNU, and vincristine was given; he did not respond to chemotherapy. His left hemiparesis deteriorated. He developed aspiration pneumonia from dysphagia and expired on October 22, 1993. The patient was discussed in a neurologic CPC, and the chief discussant arrived at the conclusion that the patient had astrocytoma grade III involving the pons, midbrain, thalamus, and the parietal cortex.(ABSTRACT TRUNCATED AT 400 WORDS)
