A 53-Year-Old Woman With Seizure and Cavitary Lung Mass.

A 53-year-old woman with no significant past medical history came to her local ED after a witnessed generalized tonic-clonic seizure. CT scan imaging of the head revealed a left frontal lobe hypodensity concerning for a mass with surrounding edema. In the previous month, she had undergone ambulatory evaluation for a subacute cough that had more recently become productive of bloody sputum. Outpatient chest radiography had demonstrated a new right lung opacity, shown on subsequent CT scan imaging to be a right upper lobe (RUL) consolidation. She was prescribed a course of doxycycline, after which sputum expectoration improved but a nonproductive cough remained. Repeat thoracic imaging was pending at the time the seizure occurred. The patient had no history of chronic lung disease or recurrent infections. There were no constitutional symptoms. She did not take any home medications on a regular basis. She was a lifetime nontobacco user. She denied use of alcohol and illicit drugs. She had previously worked in a medical office but was now spending most of her time helping her husband take care of their house and property in Kingston, New York, a town of about 23,000 people in the Hudson River Valley. She was born in the United States and had not traveled recently. She had no pets. There was no history of recent dental procedures. She was transferred to our institution for neurosurgical evaluation.
