Abstract:
In a smoking adult with a lung mass, brain masses are usually diagnosed as brain metastases of lung origin. Nevertheless, differential diagnosis between cerebral abscesses cannot be performed based on clinical symptoms or imaging technologies, and histological diagnosis is essential. This case illustrates the advisability of always obtaining histological diagnosis of the primary tumor and/or cerebral lesion before introducing any oncological treatment.
