Anamnesis

History: A 45-year-old male patient presents with a progressive headache for 10 days, located in the right frontoparietal region, with a pulsatile character and moderate to severe intensity. He reports intermittent low-grade fever and worsening of the pain with coughing or physical exertion. There is a recent history of inadequately treated bacterial sinusitis.

Neurological Examination: Mild paresis in the left hemibody and conjugate gaze deviation to the right. Fundoscopy without papilledema.

Complementary Exams: Cranial magnetic resonance imaging reveals a rounded lesion in the right frontal lobe with peripheral enhancement after contrast (brain abscess). Lumbar puncture with cerebrospinal fluid showing neutrophilic pleocytosis and elevated protein.

Report this case — e.g. suspected re-identification risk.
