70-year-old male underwent epileptic seizures. A brain CAT scan showed a space occupying lesion with surrounding edema in his left frontal lobe. A subsequent MRI examination enabled the demonstration of four separated lesions in his brain consistent with metastases. A total body CAT scan demonstrated a mass in the right lung. The diagnosis of poorly differentiated squamous cell carcinoma of the lung was established by bronchoscopy and transbronchial biopsy. The patient was treated by brain irradiation.

66-year-old male with a 6-year history of sensory symptoms in the feet and hands. He describes a sensation of cold and stinging in the feet; and numbness in the hands, especially at night. Nerve conduction and EMG demonstrated axonal and demyelinative sensorimotor neuropathy with neurogenic changes in muscles. Follow-up nerve conduction testing that was performed 2 years later showed similar findings.
