Do Cluster Headaches Cause Horner’s Syndrome?
Horner syndrome has a variety of effort which can cause it within a short period of time . bunch headacheis also one of the reasons for horner ’s syndrome . In fact , the most common benignant reason for horner ’s syndrome is vascularheadachealso known as cluster headache . According to a work transmit , about 10 % of cases hurt from clump headache are known to be suffering from horner ’s s syndrome whether sooner or later in life.(1)The precise etiology of cluster vexation also known as Horton syndrome is not known and also it is difficult to decipher how it causes the horner ’s syndrome.(2)These are characterized by round of afflictive headaches tramp from 15 – 120 minutes each and are multiple in number . These can pass off for a period of one week to one month or more and then a period of normal phase follows which can range from months to year . Although the mechanics is not quite clearly understood there is an increased flow of blood from the secular arteries mostly experience as a unilateral phenomenon . It is associated with redness of heart , lachrymation , miosis , dropping of eyelids , severeeye pain in the neck , deprivation of sudation on face , etc.(3)These are all have a go at it symptoms of horner syndrome .
Vascular headaches are the cause of ordinarily third - order horner syndrome because the fibers affected in it are site intracranially in the erectile fistula which is postganglionic in anatomic stemma . The cluster head ache can be force out by the full flow of oxygen at 100 % . aesculapian treatment can be give to cut short the onrush of cluster headache . ordinarily used drugs are non - steroidal anti - rabble-rousing drug but the most efficacious and the unexampled in business are triptan mathematical group of drug like sumatriptan , naratriptan , etc .
How Does Pancoast Tumor Cause Horner’s Syndrome?
mechanics of pancoast tumor causing Horner syndrome :
Pancoast tumour is a malignant tumor settle at the apex of the lung and is one of the most common malignant causal agent responsible for Horner syndrome after the intracranially located malignancy . For knowing the suit of Pancoast tumors cause horner syndrome , it is necessary to understand the anatomy of the sympathetic fibers . First - order neurons of the sympathetic system turn out intracranially from the hypothalamus and throw away down to the spinal cord without crossing . From the spinal corduroy , there is a rise of preganglionic charitable fibers which exits from the spinal electric cord and ascends in a parallel fashion along with the vertebral editorial and passes near the subclavian arteria and apex of the lung .
Since a Pancoast tumour is the lung tumor that is uncommon as compare to other lung Cancer get up from the apex of the lung , it can impinge the kindly nerve fibers going near the apex and thus can involve them in the pathology.(4)It , therefore , make the 2nd - social club of horner syndrome and the symptoms of miosis , ptosis can appear very early . For its treatment operative approach as well as chemo or radiotherapeutic approach can be used depending upon the extent and the needs of the patient role , but it should be treat as betimes as possible because once it damage the fiber permanently it will not be two-sided .
Conclusion
Although there are a variety of effort assort with horner syndrome but few of the commonest benignant causes are vascular headache like a bunch vexation . Apical lung tumor - alike Pancoast tumor is among the malignant reasons for horner syndrome and usually counted after the intracranial malignancy . Cluster cephalalgia or other benignant vascular headache are normally the cause of third order of horner syndrome which involves postganglionic fiber due to its chemical mechanism originating intracranially . Apical involvement like in Pancoast tumor and subclavian arterial blood vessel defect are the movement of 2nd - order of horner syndrome which includes preganglionic fibers .
