Extrapleural fat sign
Updates to Study Attributes
Total body CT done. Full; chest scanned at arterial phase and delayed phase (shown).
Deflated balloon catheter in aorta (right femoral approach), its tip at proximal end of descending aorta. Well-placed endotracheal tube and nasogastric tube. Pleural drain on each side, end-holes blocked, resultant soft tissue emphysema.Small bilateral pneumothorax (seen on lung window). Bilateral pleural effusion (haemothorax), small amount on right and moderate on left, with passive subpleural atelectasis at lung bases.Visible extrapleuralExtrapleural fat stripe visible on left denotes, separating pleural and extrapleural hematomahaematoma as well (extrapleural fat sign).Thoracic aorta preserved.Periaortic hematomahaematoma extending from T2 to T9. Within it, left paravetebralparavertebral focus of contrast material extravasation - arterial hemorrhagehaemorrhage, perhaps from vertebral artery.
Fracture atLeft clavicular fracture, lateral third of left clavicle, of T3 and T4 vertebrae, retropulsion at T4 level, exerting pressure on thecal sac. Fracture, of left transverse process of T3.Fracture, right of right ribs 1, 2, 4, 5, and 8; left ribs 5-7.
Haematoma in intrinsic muscles of back, extending between T2-T4, with contrast material extravasation not seen on arterial phase -: venous haemorrhage most probably.
Small amount of free intraeritoneal fluid, likely from diagnostic peritoneal lavage (DPL) done immediately prior to scan.
