The magnetic resonance imaging showed the right paracentral disc herniations at the C4-C5 [Figure 1a] and C5-C6 [Figure 1b] levels causing anterolateral cord compression and clinically, cervical myelopathy- radiculopathy.
Sagittal (left) and axial (right) CT scan sequences showing a significant right laterocervical and retrotracheal hematoma determining compression of the upper aerodigestive structures.

The cervical CT scan with/without contrast showed marked enlargement of the retrotracheal space due to an extensive hematoma [Figure 2] in the right lateral/retrotracheal soft tissues; with contrast, the bleed appeared to originate from a branch of the right superior thyroid artery [Figures 3 and 4].
Sagittal (left) and axial (right) CT angiography scan sequences showing a grown up hematoma a few minutes away, the yellow arrow indicates the origin of the bleeding from the right superior thyroid artery.

The cervical CT scan with/without contrast showed marked enlargement of the retrotracheal space due to an extensive hematoma [Figure 2] in the right lateral/retrotracheal soft tissues; with contrast, the bleed appeared to originate from a branch of the right superior thyroid artery [Figures 3 and 4].
3D CT angiography reconstruction of the epiaortic arterial vessels: the green arrow highlights the point of leakage (*) of the contrastum medium from the right superior thyroid artery.

The cervical CT scan with/without contrast showed marked enlargement of the retrotracheal space due to an extensive hematoma [Figure 2] in the right lateral/retrotracheal soft tissues; with contrast, the bleed appeared to originate from a branch of the right superior thyroid artery [Figures 3 and 4].
Post-operative sagittal (left) and axial (right) CT angiography scan sequences proving the successful evacuation of the retro-tracheal hematoma and the absence of further vessel abnormalities.
