Tenosynovial giant cell tumors of digits: MRI differentiation between localized types and diffuse types with pathology correlation

Objective To compare the MRI findings between the localized- and diffuse-type tenosynovial giant cell tumors (TSGCTs) of digits with pathology correlation. Methods Twenty-eight patients with newly diagnosed TSGCTs of digits (22 localized and 6 diffuse types) who underwent preoperative MRI and surgic...

Description
Summary:Objective To compare the MRI findings between the localized- and diffuse-type tenosynovial giant cell tumors (TSGCTs) of digits with pathology correlation. Methods Twenty-eight patients with newly diagnosed TSGCTs of digits (22 localized and 6 diffuse types) who underwent preoperative MRI and surgical excision were included from Jan. 2015 to September 2021. MRI findings regarding nodularity, margins, morphology of hypointensity with pathology correlation, and disease extent (bone erosion, articular involvement, muscle involvement, tendon destruction, and neurovascular encasement) were assessed. Results Diffuse type was significantly larger ( P  = 0.006), more multinodular on both MRI and pathology ( P  = 0.038, both) with significant agreement, and infiltrative on both MRI and pathology ( P
