The extraoral examination revealed hard uniform and large expansile
mass in the left side of the mandible.
One treatment involves the Insertion of an expansile
material, such as hydrogel, for occlusion.
Macroscopic histopathological examination revealed an 8x2x1.5-cm expansile
mass, and microscopic examination revealed a lesion of dimensions 5.5x2x0.8 cm with 0.8-cm tumour-free resection margins.
Chest CT showed multiple massive expansile
osteolytic rib lesions.
On contrast-enhanced images, tumor is characteristically seen as an expansile
soft tissue mass, as opposed to perianal fistulas, and demonstrate intense contrast enhancement.
CT demonstrates an expansile
, well-defined mass within the petrous apex with cortical thinning.
MRI of the lumbar spine demonstrated multiple, multilevel T1 and T2 hypointense lesions and pathologic compression fracture with posterior expansile
mass at L1 causing severe spinal and neural foraminal stenosis (Figure 2).
After radioiodine therapy, contrast enhanced arterial phase multi-slice computed tomography (MSCT) of the thoracic and abdominal region demonstrated an expansile
left adrenal gland mass sized 7.8 cm in diameter with inhomogeneous contrast opacification, including a central low attenuation area of necrosis (Fig.
The lesion was clearly expansile
, enlarging the confines of the left frontal sinus.
Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a sphenoid-based locally expansile
cystic lesion (Figs 2 and 3).
The elbow radiograph showed an expansile
osteolytic lesion with surrounding sclerosis and a narrow zone of transition in the proximal metaphysis of the right ulna.
Rather than the infiltrative pattern typically seen at the deep edge of conventional invasive squamous cell carcinoma, verrucous carcinoma demonstrates insidious pushing-type invasion by expansile
and irregular rete pegs (4x, H&E stain).
