Figure 1. Sagittal T2-weighted MRI showing the teardrop lesion, which is relatively isointense to intervertebral disc and obstruct the canal (a); myelogram showing partial obstruction at L5 level (b); axial T2-weighted cuts showing the polygonal shape of lesion, which is clearly distinct from dural sac and occupies the neural foramina (c).
Figure 2. Intraoperative photograph showing the lesion in situ (yellow circle), which became visible after partial laminectomy. The dural sac (asterisk) is drawn laterally by a Love retractor.
Figure 3. The photomicrograph of lesion showing invasive ductal carcinoma (Hematoxylin and Eosin; × 200 and × 400)
