Orbital pseudotumor

Introduction to pseudotumor Pseudotumoroftheorbit (pseudotumoroftheorbit) is a non-specific chronic proliferative inflammation. It is named for its true symptoms. It is not uncommon for pseudotumor. The tumor has diffuse, limited, and can occur at all ages. More patients. In the aura, there is pain in the distribution of the ocular nerves, accompanied by tearing, conjunctival edema and eyeball protrusion. In the developmental period, the eyeball rapidly protrudes to the front and can not be reset, and the eyelids and conjunctival edema are intensified, and early eye movement disorders even appear. Significant loss of vision, most of the lumps around the rim of the eyelid or deep in the eyelid can be touched, occasionally when the eyeball is compressed, the retinal vein dilates, the papilledema and retinal choroiditis change, the disease is self-limiting, develops to a certain degree After the stage, the mass of the mass is fibrotic and the lesion tends to be stable. basic knowledge Sickness ratio: 0.0001% Susceptible people: good for middle-aged men Mode of infection: non-infectious Complications: meningitis

Cause of pseudotumor

It is not uncommon for a pseudotumor to be present. The tumor has a diffuse person, and there are limitations. It can occur at all ages, and there are more male patients. The causes of this disease are as follows:

1, regional infections such as sinusitis, scleritis, chorioretinitis, etc.;

2, lesions such as dental caries, alveolar abscess, osteomyelitis, skin infections;

3, vascular causes such as iliac vein embolization, nodular arteritis;

4, allergic reaction;

5. Stimulation of adipose tissue necrosis on the basis of poisoning, hypoxia, and vascular changes.

pseudotumor prevention

This tumor patient is more male than female, and the age is more than middle-aged. Pay attention to eye examination, pay special attention to eye hygiene and hand hygiene, prevent the occurrence of eye diseases, early diagnosis and early treatment.

Pseudotumor complications Complications meningitis

Complications of the disease include supraorbital vein embolism, cavernous sinus embolization, ophthalmoplegia, V-neural paralysis, meningitis and the like.

Symptoms of pseudotumor common symptoms eyelid pain, tears, eyeballs, visual impairment, conjunctival edema, corneal ulcer, papilledema, diplopia, eyelid, foreign body, bone destruction, keratitis

In the aura, there is pain in the distribution of the ocular nerves, accompanied by tearing, conjunctival edema and eyeball protrusion. In the developmental period, the eyeball rapidly protrudes to the front and can not be reset, and the eyelids and conjunctival edema are intensified, and early eye movement disorders even appear. Significant loss of vision, most of the lumps around the rim of the eyelid or deep in the eyelid can be touched, occasionally when the eyeball is compressed, the retinal vein dilates, the papilledema and retinal choroiditis change, the disease is self-limiting, develops to a certain degree After the stage, the mass of the mass is fibrotic and the lesion tends to be stable.

pseudotumor examination

1, due to granulation hyperplasia, easy to cause sputum circulation disorders, often conjunctival congestion, edema and eye pain, but the pressure on the fundus is rare.

2, there is self-limiting, the late eyeball will automatically stop, and even collapse due to scar contraction.

3, X-ray film, only a small number of visible sacral cavity expansion, often no bone destruction, most have sinusitis, some can see thickening of the periosteum in the sacral, sacral hyperplasia and other phenomena.

4. Thickened extraocular muscles or borderless proliferative tissue can be seen on B-mode ultrasound images and CT slices. The pseudotumor is either inside the muscle cone or outside the muscle cone.

Diagnosis and diagnosis of pseudotumor

Pseudotumor should be differentiated from true tumors. In recent years, due to advances in clinical diagnostic methods and techniques, the diagnostic level of pseudotumors has been greatly improved. The main diagnostic points are:

1. Early development is faster, while general true tumors develop slowly;

2. Extraocular muscles are easily affected, so eye movement disorders and diplopia appear earlier.

3. Due to granulation hyperplasia, it is easy to cause sputum circulation disorder, often conjunctival congestion, edema and eye pain, but the fundus is rarely pressed;

4. Self-limiting, the late eyeball will automatically stop, and even collapse due to contraction of the scar;

5. X-ray film, only a few visible cavity enlargement, often no bone destruction, most have sinusitis, some can see thickening of the periosteum in the iliac crest, hypertrophy of the tibia;

6. Thickened extraocular muscles or borderless proliferative tissue can be seen on B-mode ultrasound images and CT slices, with pseudotumors either in the muscle cone or outside the muscle cone;

7. Some pseudotumors have reduced symptoms after treatment with antibiotics or hormonal drugs, and the eyeballs can be significantly improved. Even after the inflammation subsides, the eyeballs are retracted, but true tumors do not have such a reaction, so it is difficult to identify the truth in the clinic. In the case of a pseudotumor, the above drugs can be used for experimental treatment, which is both a treatment and a differential diagnosis for a pseudotumor;

8. For cases that are difficult to make a differential diagnosis, only biopsy can avoid misdiagnosis.
