Hauv xyoo 1911, kws kho mob hlwb Robert Foster-Kennedy tau txheeb xyuas qhov tsis tau piav qhia yav dhau los los ntawm kev tshuaj xyuas cov ntaub ntawv kho mob. Nws cov ntsiab lus muaj nyob rau hauv kev nce zuj zus ntawm cov hlab ntsha thiab lub caij nplooj zeeg hauv kev pom kev pom ntawm thawj lub qhov muag nrog kev loj hlob ntawm cov paj hlwb nyob rau hauv qhov thib ob.

ua rau ntawm pathology

Foster-Kennedy Syndrome tuaj yeem tshwm sim los ntawm cov xwm txheej hauv qab no:

  • neoplasms lossis purulent o ntawm lub hlwb;
  • tawm ntawm phab ntsa ntawm cov hlab ntsha ntawm lub hlwb;
  • mob khaub thuas meninges;
  • TBI qhib lossis kaw hom;
  • Echinococosis ntawm lub hlwb;
  • aortic sclerosis.

Ntxiv rau cov xwm txheej saum toj no, pathology tuaj yeem tshwm sim nyob rau hauv kev cuam tshuam ntawm cov kab mob ntawm lub orbit:

  • arachnoidendothelioma loj hlob rau hauv pob txha taub hau los ntawm sab sauv;
  • retrobulbar gumma txuam nrog luetic meningitis.

Tus kab mob tuaj yeem ua rau muaj kev puas tsuaj loj hauv lub hlwb hauv ib qho twgthaj chaw (occipital, temporal, frontal los yog parietal) raws li cov tsos mob nyob rau hauv lub zej zog los yog cov tsos mob ntawm qhov deb. Lub sij hawm tom kawg yog hais txog kev hloov ntawm lub hlwb los ntawm ib qho neoplasm lossis los ntawm lub ventricular loj.

Mechanism of disease

Foster-Kennedy syndrome yog tus cwj pwm los ntawm kev pib compression ntawm intracranial feem ntawm cov paj hlwb. Yog li ntawd, ib txwm atrophy yog tsim. Yog hais tias pathology nce, lub siab nyob rau hauv lub cranium nce. Nyob rau hauv lem, qhov no provokes lub txiv mis congestion nyob rau hauv lwm lub qhov muag. Nyob rau tib lub sijhawm, qhov tshwm sim zoo sib xws tsis tshwm sim hauv qhov pib cuam tshuam qhov muag vim qhov atrophy ntawm cov kwj dej optic.

Ib qhov muag emaciated feem ntau yog ua rau lub hauv nruab nrab scotoma ntawm nws, uas nyob ntawm qhov poob ntawm cov ntshav zoo rau cov papillomacular pob hauv thaj tsam intracranial ntawm lub paj hlwb.

Stagnation ntawm lub txiv mis ntawm lwm lub qhov muag tuaj yeem ua rau tsis yog los ntawm kev dhia hauv siab nce mus rau hauv lub cranium, tab sis kuj los ntawm kev cuam tshuam ntawm cov kab mob tseem ceeb ntawm ntu intracranial ntawm ob lub paj hlwb - chiasm. Yog li ntawd, nrog Foster-Kennedy syndrome, neurology distinguishes yooj yim thiab nyuaj lub txiv mis congestion. Qhov teeb meem yog tus cwj pwm los ntawm kev nqaim ntawm qhov pom kev.

Stages

Cov chav kawm ntawm pathology mus dhau cov theem hauv qab no:

  1. Central scotoma raug kuaj pom ntawm ib lub qhov muag, qhov nyiaj tsis muaj qhov tsis txaus ntseeg. Lwm qhov muag muaj txiv mis congestion.
  2. Rau lub hauv paus scotoma ntawm ib lub qhov muagdepletion ntawm cov hlab ntsha optic ntxiv. Tseem muaj congestion nyob rau lwm qhov muag.
  3. thawj pob qhov muag dig muag vim lub paj tawg tag. Secondary nkim tsim nyob rau hauv lwm lub qhov muag.

Nws tsim nyog sau cia tias cov theem saum toj no tuaj yeem tsis yog theem ntawm Foster-Kennedy syndrome, tab sis tsuas yog nws cov subspecies uas tau tsim los ntawm ib leeg.

"Rov qab" pathology

Qee zaum, nrog kev txhim kho ntawm neoplasms ntawm lub hlwb, thim rov qab Foster-Kennedy syndrome tuaj yeem tshwm sim. Ntawd yog, lub txiv mis congestion los ntawm ib tug benign los yog malignant neoplasm thiab cov paj hlwb ib txwm depletion ntawm lwm lub qhov muag. Qhov no yog qhov tshwm sim ntawm qhov hloov pauv ntawm cov kab mob optic kwj dej. Thaum lub sij hawm kev loj hlob, lub neoplasm hloov lub hlwb mus rau lwm sab, uas compresses intracranial feem ntawm lub paj hlwb. Tom qab nce siab hauv lub cranium provokes stagnation ntawm lub txiv mis los ntawm sab ntawm lub dislocation ntawm neoplasm. Yog li, thim rov qab Foster-Kennedy syndrome yog cov tsos mob tshem tawm.

Diagnosis

Txhawm rau kuaj mob, koj yuav tsum tau sab laj nrog kws kho mob hlwb thiab kws kho mob hlwb. Tsis tas li ntawd, yuav tsum xeem dhau ntau qhov kev xeem:

  • ophthalmoscopy;
  • ntsuas qhov pom nrog ob phau ntawv thiab tsis siv neeg zoo li qub perimetry;
  • visometry;
  • CT scan ntawm lub hlwb;
  • magnetic resonance duab ntawm lub hlwb;
  • MRI angiography (raws li qhia).

Yog tias qhov kev kuaj mob sib txawv ntawm tus mob prechiasmatic yog qhov tsim nyog, ces nws yuav tsum tau ua nrog retrobulbar, optic neuritis, nrog rau macular degeneration thiab posterior ischemic neuropathy..

Kev kho mob ntawm Foster-Kennedy syndrome

Kev kho mob ntawm pathology nyob ntawm qhov chaw ntawm cov qog pom los yog qhov quav. Feem ntau ua los ntawm kev phais lossis kev kho hluav taws xob.

Cov kab mob zoo sib xws

Yog tias ib lub qhov muag tau tsim cov txiv mis congestion, thiab lwm qhov muaj qhov nkig thib ob (lossis 5th theem ntawm lub txiv mis congestion) lossis disc atrophy nrog residual stagnation (4th theem), ces cov no tsuas yog txiv mis nrog stagnation uas muaj teeb meem. Tus kab mob no tsis muaj dab tsi ua rau Foster-Kennedy syndrome.

Tsis tas li, tsis txhob cuam tshuam cov kab mob no nrog rau cov neeg mob tuag ntawm cov hlab ntsha optic cuam tshuam nrog disc edema ntawm lwm cov kua, uas tshwm sim tawm tsam keeb kwm ntawm ischemic paj pinching lossis retrobulbar neuritis.
