A 70-year-old man with a history of small cell lung carcinoma presented with suspected paraneoplastic limbic encephalitis. Brain (18)FDG PET/CT confirmed limbic encephalitis with bilateral amygdalian and hippocampal hypermetabolism, while whole-body (18)FDG PET/CT revealed metastatic recurrence of small cell lung carcinoma. Follow-up (18)FDG PET/CT after chemotherapy showed normalization of brain metabolism and partial metabolic response of the metastatic recurrence, consistent with good clinical neurological evolution. This case highlights the clinical-metabolic imaging correlation in paraneoplastic limbic encephalitis.
A 70-year-old man with a history of small cell lung carcinoma 2 years earlier was addressed for the suspicion of a paraneoplastic limbic encephalitis. Brain (18)FDG PET/CT revealed a bilateral amygdalian and hippocampal hypermetabolism, confirming a limbic encephalitis, and concurrent whole-body (18)FDG PET/CT showed a small cell lung carcinoma plurifocal metastatic recurrence, consistent with a paraneoplastic limbic encephalitis. (18)FDG PET/CT follow-up under chemotherapy revealed an almost complete normalization of brain metabolism and a partial metabolic response of the metastatic recurrence, consistent with the good clinical neurological evolution of the patient. This case highlights the clinical-metabolic imaging correlation in paraneoplastic limbic encephalitis.
