Case in brief
A 61-year-old woman with metastatic small cell lung carcinoma presented with a persistent tremor in her right upper limb. Initial brain MRI results were normal, but 18 F-FDG PET/CT revealed hypermetabolism in the left precentral gyrus. A follow-up MRI two weeks later showed cortical enhancement that corresponded with the PET findings, confirming the presence of a metastatic lesion.
Diagnostic / clinical pearl
This case highlights the utility of 18 F-FDG PET/CT in identifying symptomatic brain metastases when MRI results are inconclusive.
