High grade glioma recurrence presenting as extensive tumor thrombus and simultaneous pulmonary metastasis revealed on 18F-FDG PET/CT.

Abstract

Extensive tumor thrombus and simultaneous pulmonary metastasis in glioma patient is rare. Herein, we reported a 45-year-old woman with extensive tumor thrombus in sagittal sinus and sigmoid sinus with obvious enhancement on magnetic resonance imaging (MRI). Fluorine-18-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT) showed extensive tumor thrombus in sagittal sinus, sigmoid sinus andinternal jugular vein, and simultaneous left hilar lymph node andpulmonary metastasis. Our case demonstrated the value of ¹⁸F-FDG PET/CT for correctly identifying tumor thrombus,detecting extent of tumor thrombus and distant metastasis in high grade glioma patients.
