Brain Abscess in a Patient with Rendu-Osler-Weber Syndrome: Value of Proton Magnetic Resonance Spectroscopy
نویسندگان
چکیده
The diagnosis of intracranial focal lesions based on imaging studies is a challenge. In brain abscess, proton magnetic resonance spectroscopy (1H-MRS) is useful to define etiology, differentiating anaerobic from aerobic pathogens and inclusive sterile abscess based on the behavior of certain metabolites. We report a patient with Rendu-Osler-Weber syndrome, pulmonary arteriovenous fistulas, and brain abscesses characterized by brain magnetic resonance imaging (MRI), with a spectroscopy pattern compatible with anaerobic infection.

Brain abscess caused by pulmonary arteriovenous fistulas without Rendu-Osler-Weber disease.
A 52-year-old man was admitted with a brain abscess in the left basal ganglia. He had a paradoxical brain embolic mechanism owing to a pulmonary arteriovenous fistula (PAVF) and was diagnosed as having a right-to-left shunt by transesophageal echocardiography (TEE) and transcranial color Doppler (TCD) with saline contrast medium. We determined that the brain abscess was caused by the PAVFs with...
