There is only minimal FDG activity distributed heterogeneously in the very large mass centred in the superior right hemithorax. There is associated partial collapse of the right upper, middle and lower lobes. These findings suggest a low-grade neoplastic process.
There is minimal nonspecific FDG activity in the large right pleural effusion, small left pleural effusion, and along the left lateral pleural margin.
Minimal FDG activity in the left lower paratracheal mediastinal nodes is non-specific.
Intense FDG activity in the interatrial septum is without structural CT correlate and explainable by a benign cause (eg lipomatous hypertrophy of the interatrial septum).
No increased FDG activity is demonstrated in the splenic granuloma or in the thoracolumbar vertebral body haemangiomas. No increased FDG activity is demonstrated in the multinodular goitre.
No further abnormal foci of increased FDG activity are demonstrated in the neck, chest, abdomen or pelvis to suggest FDG avid malignant disease.
