Description
Summary:A 60-year-old man presented with a 25-day history of acute onset instability of gait, tremulousness of limbs and involuntary eye movements. Examination revealed presence of opsoclonus, myoclonus and ataxia, without any loss of motor power in the limbs. Prompt investigations were directed towards identifying an underlying malignancy which is often associated with this type of clinical scenario. CT of the brain was normal and cerebrospinal fluid examination showed lymphocytic pleocytosis. A cavitatory lesion was found in the right lung base on the high-resolution CT of the chest and histopathological examination of this lung mass showed small cell lung carcinoma. The patient was managed symptomatically with levetiracetam and baclofen and referred to oncology department for resection of the lung mass.
