Mucoceles are locally expansile
paranasal sinus cysts characterized by mucous effusion.
Maxillofacial CT additionally demonstrated diffuse loss of corticomedullary differentiation with near complete, symmetric replacement of the osseous matrix of the mandible and maxilla with expansile
The computed tomography (CT) sections showed a large expansile
lesion in the left ramus of the mandible.
14,16) Grossly, tumors may be infiltrative or expansile
and those with mucin production are soft and gelatinous.

lesion with narrow zone of transition and no matrix.
He also had a large painless, pulsatile and expansile
mass extending two finger breaths above the umbilicus.
The presence of expansile
sellar lesion, showing restricted diffusion signal pattern compatible with acute pituitary pyogenic abscess was found on MRI.
Microscopically, they are characterized by dense well vascularized stroma populated by expansile
mass of stellate fibroblasts surrounded by variable amounts of densely packed fibrillar collagen, resembling periodontal ligament.
Gross examination revealed multifocal, soft, round, expansile
, pale tan masses of variable sizes that had replaced or effaced the normal architecture of the tracheobronchial lymph nodes and pulmonary parenchyma.
6] Though the clinical features are nonspecific, majority of cases are present as expansile
lesions associated with pain.
23 Various programmable shunts are available in the market to cater to low expansile
force of maximal hydrocephalus patients, but no advantage was found in using a shunt system that is prohibitively expensive.
mass-like lesion in the pons was also noted which was heterogeneously hyperintense on T2-weighed imaging and demonstrated heterogeneous enhancement on contrast administration (Figures 8 and 9).
