Figures
- Fig 1.
Axial contrast-enhanced CT shows a relatively well-circumscribed tongue mass with slightly greater peripheral enhancement and central areas of low attenuation due to tumor necrosis.
- Fig 2.
A, Sagittal T1-weighted unenhanced image shows a hyperintense signal intensity lesion in tongue with central low signal intensity representing an area of tumor necrosis.
B, Axial T2-weighted image shows a large hyperintense lesion in the tongue with a central region of greater signal intensity (long arrow) due to necrosis. A few scattered flow voids (short arrows) are seen within the lesion consistent with the diagnosis of ASPS.
C, Axial contrast-enhanced T1-weighted image shows intense heterogeneous enhancement with an internal area of low signal intensity due to necrosis (long arrow). Flow voids are once again seen (short arrow).
- Fig 3.
Lateral-projection angiograms acquired during mid- (A) and late (B) arterial phases show a hypervascular mass with irregular, tortuous tumor vessels and persistent tumor blush. An early draining vein is seen at the base of tongue (arrow).
