Abstract

Carbon-11 methionine (11 C-Methionine) is a radio-labeled amino acid currently utilized in Positron Emission Tomography (PET) for imaging primary and metastatic brain tumors. Its clinical use relies mostly on oncologic applications, but the tracer has the potential to investigate other non-malignant conditions. So far, very limited evidence concerns the use of 11 C-Methionine in patients suffering from seizure; however, the tracer can find a proper utilization in this setting especially as a diagnostic complement to 18 F-Fluorodeoxyglucose (18 F-FDG).

Herein we report the case of a 57-year-old patient presenting with epileptic crises secondary to a brain metastasis from bladder carcinoma, who was investigated in our institution with 11 C-Methionine PET. The scan documented the disease recurrence in the left parietal lobe associated with a diffused tracer uptake in the surrounding cerebral circumvolutions, derived from the comitial status. After surgical removal of the metastatic lesion, the patient experienced a complete recovery of symptoms and no further onset of secondary seizure.

Resumen

La 11 C-metionina es un aminoácido radiomarcado que se utiliza actualmente en la tomografía por emisión de positrones (PET) para obtener imágenes de tumores cerebrales primarios y metastáticos. Su aplicación clínica más extendida es la oncología, pero tiene el potencial de investigar otras situaciones no oncológicas. Hasta el momento existe una limitada evidencia del uso de 11 C-metionina en pacientes con crisis convulsiva; sin embargo, el radiotrazador puede tener utilidad en este campo especialmente como complemento diagnóstico de la 18 F-fluorodeoxiglucosa (18 F-FDG). Presentamos el caso de un paciente de 57 an¿ os de edad con crisis epilépticas secundarias a metástasis cerebrales de un carcinoma de vejiga que fue explorado en nuestra Institución con 11 C-metionina PET. El estudio demostró la recidiva de la enfermedad en el lóbulo parietal izquierdo asociada con captación difusa en las circunvoluciones cerebrales de alrededor, derivada del status comicial. Después de la extirpación quirúrgica de la metástasis cerebral, el paciente experimentó una recuperación completa de los síntomas sin posterior inicio de crisis convulsivas secundarias.
