- Oral mucocele (also mucous extravasation cyst, mucous cyst of the oral mucosa, and mucous retention and extravasation phenomena. (wikipedia.org)
- As the MRCMS pathogenesis seems to be based on hypothesis, many denominations are attributed to this injury: pseudocyst, the retention cysts of the maxillary sinus, serous cyst, mucous cyst, benign maxillary mucous cyst or mucocele. (bvsalud.org)
- Although these lesions are often called cysts, mucoceles are not true cysts because they have no epithelial lining. (wikipedia.org)
- Orbital tumors can be benign or malignant and arise primarily within the orbit or secondarily from an adjacent source, such as the eyelid, paranasal sinus, or intracranial compartment. (msdmanuals.com)
- Some mucoceles spontaneously resolve on their own after a short time. (wikipedia.org)
- Radiographically this lesion appeared as a mucocele because of its expansile nature, however non-traumatic mucoceles have not been associated with cerebrospinal fluid rhinorrhea. (mssm.edu)
- Pneumatization occurs when a paranasal sinus, often the sphenoid or ethmoid sinus, extends into the anterior clinoid process via the inferior or anterior root otherwise known as the optic strut. (openaccesspub.org)
- A variant of a mucocele is found on the palate, retromolar pad, and posterior buccal mucosa. (wikipedia.org)
- The injury appears in panoramic and periapical radiographs of maxillary posterior teeth as a homogeneous radiopacity, outlined, dome-shaped, hemispherical or circular, of variable dimensions, most frequently located on the floor of the maxillary sinus, and preserving the sinus walls. (bvsalud.org)
- The mucocele has a bluish, translucent color, and is more commonly found in children and young adults. (wikipedia.org)
- When found on the floor of the mouth, the mucocele is referred to as a ranula. (wikipedia.org)
- The size of oral mucoceles vary from 1 mm to several centimeters and they usually are slightly transparent with a blue tinge. (wikipedia.org)
- 1, 2] Historically mistaken for a paranasal sinus tumor, allergic fungal sinusitis (AFS) now is believed to be an allergic reaction to aerosolized environmental fungi, usually of the dematiaceous species, in an immunocompetent host. (medscape.com)
- Moreover, patients with allergic fungal sinusitis (AFS) appear to demonstrate a broad sensitivity to a number of fungal and nonfungal antigens. (medscape.com)
- This study appears to emphasize the importance of both skin testing and specific IgE testing via RAST in initial evaluation of patients in whom allergic fungal sinusitis (AFS) is suspected. (medscape.com)
- The injury appears in panoramic and periapical radiographs of maxillary posterior teeth as a homogeneous radiopacity, outlined, dome-shaped, hemispherical or circular, of variable dimensions, most frequently located on the floor of the maxillary sinus, and preserving the sinus walls.

- A variant of a mucocele is found on the palate, retromolar pad, and posterior buccal mucosa. (wikipedia.org)
- Дитяча гемангіома Infantile hemangiomas are raised, red or purplish, hyperplastic vascular lesions appearing in the first year of life. (msdmanuals.com)
- Microscopically, mucoceles appears as granulation tissue surrounding mucin. (wikipedia.org)
- Orbital tumors can be benign or malignant and arise primarily within the orbit or secondarily from an adjacent source, such as the eyelid, paranasal sinus, or intracranial compartment. (msdmanuals.com)
- On a CT scan, a mucocele is fairly homogenous, with an attenuation of about 10-18 Hounsfield units. (wikipedia.org)
- iii As with MeSH, many terms appear here in direct form (myelin sheath internodes), many in inverted form (arteritis, senile), and many in both (entries taken from the TUMOR MANUAL). (nih.gov)
- Those taken from MeSH definitions available are almost always in the direct form, copied as they appear there (familial muscular subaortic stenosis). (nih.gov)
- The size of oral mucoceles vary from 1 mm to several centimeters and they usually are slightly transparent with a blue tinge. (wikipedia.org)
- Other pediatric head and neck problems, such as the ear, laryngeal, and adenotonsillar disease, appear to be similar in prevalence and pathophysiology to those in patients without CF. (medscape.com)
- However, this reaction does not appear to be fungal specific. (medscape.com)
