Frontal glioma presenting as anxiety and obsessions: a case report.

A 53-year-old gentleman is described, who presented with acute onset of anxiety and obsessional symptoms. The clinical picture was complicated by the presence of mild alcohol withdrawal symptoms and history of excessive drinking for 20 years. A month later, he developed right hemiparesis. CT scan revealed a left frontal tumour, and on histology this was found to be Grade 4 astrocytoma.
