Castleman's disease (CD) appears at ubiquitous lymph nodes. To date, detection of the lesion focus for CD has mainly been carried out by physical examination and radiological findings, such as X-ray analysis, CT and MRI. 18F-FDG PET visualizes the active focus of glucose metabolism and the clinical value has been investigated for many different tumours. ⋯ In this paper, we report two cases of CD, one with unicentric CD and one with multicentric CD. We demonstrate that the use of 18F-FDG PET for the detection and monitoring of patients with CD, especially multicentric CD, would be effective.
