Imaging characteristics of tenosynovial giant cell tumors on ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography: a retrospective observational study.

ABSTRACT:

Background

¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG-PET/CT) is useful for assessing location, metastasis, staging, and recurrence of malignant tumors. Tenosynovial giant cell tumor (TSGCT) is a benign tumor; however, some studies have reported that TSGCTs have a high uptake of FDG. Few studies have reported on the detailed evaluation of TSGCT using ¹⁸F-FDG-PET/CT. The purpose of the current study is to evaluate the image characteristics and locations, particularly where possible, with or without, extra-articular invasion from TSGCT of the knee in ¹⁸F-FDG-PET/CT could occur.

Methods

We retrospectively reviewed the patients with TSGCT who were diagnosed pathologically either by biopsy or surgic
