Dacryoscintigraphy (DSG), also known as lacrimal scintigraphy, is a nuclear medicine technique for imaging the lacrimal apparatus. It is used to identify obstructions, for example in the lacrimal duct , nasal cavity or nasolacrimal duct .
Involutional stenosis is probably the most common cause of nasolacrimal duct obstruction in older people. It affects women twice as frequently as men. Although the inciting event in this process is unknown, clinicopathologic study suggests that compression of the lumen of the nasolacrimal duct is caused by inflammatory infiltrates and edema.
Adenoid cystic carcinoma is a rare type of cancer that can exist in many different body sites. This tumor most often occurs in the salivary glands, but it can also be found in many anatomic sites, including the breast, [1] [2] lacrimal gland, lung, brain, Bartholin gland, trachea, and the paranasal sinuses.
Historically, bilateral parotid and lacrimal gland enlargement was characterized by the term Mikulicz's disease if the enlargement appeared apart from other diseases. If it was secondary to another disease, such as tuberculosis, sarcoidosis, lymphoma, and Sjögren's syndrome, the term used was Mikulicz's syndrome.
Sialography (also termed radiosialography) is the radiographic examination of the salivary glands. It usually involves the injection of a small amount of contrast medium into the salivary duct of a single gland, followed by routine X-ray projections. [1] The resulting image is called a sialogram.
Unless the individual has an impaired immune system, e.g., owing to HIV or cancer-related immune suppression, [22] recurrent infections tend to be mild in nature and may be brought on by stress, sun, menstrual periods, trauma or physical stress. [23] Mumps of the salivary glands is a viral infection of the parotid glands.
The lacrimal gland is a compound tubuloacinar gland, it is made up of many lobules separated by connective tissue, each lobule contains many acini.The acini composed of large serous cells which, produce a watery serous secretion, serous cells are filled with lightly stained secretory granules and surrounded by well-developed myoepithelial cells and a sparse, vascular stroma.
Dacryocystitis is an infection of the lacrimal sac, secondary to obstruction of the nasolacrimal duct at the junction of the lacrimal sac. [1] The term derives from Greek dákryon 'tear' cysta 'sac' and -itis 'inflammation'. [2] It causes pain, redness, and swelling over the inner aspect of the lower eyelid and epiphora.
