Dural amyloidoma is an unusual presentation of central nervous system amyloidosis. A 49-year-old woman presented with 1-month history of repeated episodes of vertigo. Precontrast MRI showed dural thickening over right frontal convexity with signal intensity similar to white matter. Postcontrast T1-weighted images showed remarkable enhancement of the lesion. Dural amyloidoma was confirmed by partial resection of the lesion. The patient underwent no further treatment. A follow-up FDG PET/CT showed increased FDG uptake of the residual dural amyloidoma. This case indicates dural amyloidoma should be included in the differential diagnosis of abnormal FDG uptake in dural lesions.
