What is a unilocular lesion?
Unilocular cystic lesion, no solid component: (A) A simple cyst that is a subcategory of a unilocular cyst that has no internal elements, thus anechoic, a smooth thin wall, acoustic shadowing, and no internal septations (complete or incomplete).
Which of the following is the most common lesion of the mandible?
Odontoma is the most common odontogenic tumor of the mandible, accounting for approximately 67% of all cases (,6). The lesion consists of various tooth components, including dentin and enamel, which have developed abnormally to form a “hamartomatous” lesion.
What is a radiolucent lesion?
The radiolucent lesion has a broad border of transition and has destroyed the lateral cortex of the bone. There is minimal reaction of the bone to the lesion. Another possible diagnosis is metastatic carcinoma.
What is a multilocular lesion?
Introduction Multilocular radiolucency refers to a lesional appearance on the radiograph which is derived from erosion, bosselation, or scalloping of the endosteal surface at the advancing margin of the lesion, thus giving the charecteristic multiple loculated appearance.(1)
What is unilocular Radiolucency?
Unilocular anterior mandibular radiolucencies represent an aberrant or less common site for pathologies commonly occurring in body and angle region. Anterior lesions are more common in females. Most cases report with painless intraoral or extraoral swelling. Expansion occurs more at upper border of buccal cortex.
What is unilocular cystic structure?
Simple cysts are unilocular and have a uniformly thin wall surrounding a single cavity that contains no internal echoes. These cysts are likely to be functional. In contrast, complex cysts are multilocular and may have a thickened wall; these cysts may be benign or neoplastic.
What does non odontogenic mean?
A lesion associated with an impacted tooth frequently indicates an odontogenic origin. Nonodontogenic lesions, however, develop from osseous origin and are not tooth-related. These lesions usually, but not always, consist of a group of pathologies which may be seen anywhere in the axial skleton.
Is tooth vital in Cementoblastoma?
But may be associated with diffuse pain and tooth mobility, but the tooth is still vital. Since a cementoblastoma is a benign neoplasm, it grossly forms a mass of cementum-like tissue as an irregular or round mass attached to the roots of a tooth, usually the permanent mandibular first molar.
What does periapical lucency mean?
Periapical lucencies are often seen incidentally at head and neck imaging studies performed for indications not related to the teeth. These lesions are, however, occasionally manifestations of diseases that have a wide range of effects and may at times represent the source of symptoms that prompted the study.
What is unilocular cyst?
A unilocular tumor was defined as a fluid-filled cyst without internal septa, papillary projections, or solid components (Figure 1).
What is a Globulomaxillary cyst?
Globulomaxillary cyst is an uncommon, specious cyst. It was traditionally described as a fissural cyst between the maxillary lateral incisor and canine teeth, secondary to proliferation of entrapped epithelium between the globular portion of the medial nasal and maxillary processes.
What is unilocular mean?
: containing a single cavity.
