Abstract

Abstract : Abstract: A 63-year-old woman with a history of malignant schwannoma in the left shoulder (pT1aNxMx) was treated with surgical resection in 2012. During follow-up, patient developed a metastasis in the right lung treated by further surgical intervention. For a suspicion on persistent disease in the lung, patient was sent to FDG PET/CT examination, which showed a focal uptake in the gallbladder. The patient underwent cholecystectomy, and a solitary metastasis from schwannoma was diagnosed by pathology. This case highlights that, in patients with a malignant schwannoma, a careful differential diagnosis should be made in case of a significant FDG uptake in the gallbladder.
