Diagnosis is an important part in the management of brass sheath tumor . The diagnosis help the medico in identifying the presence of nerve sheath tumour , whether it is benignant or malignant , and extent of metastasis and the stage of the disease . This will help the oncologist in value the prognosis of the disease and also helps in create an optimum treatment strategy . former diagnosis is really significant for favourable medical prognosis and is now possible due to extremely sophisticated and computerized diagnostic technique .
How Is Nerve Sheath Tumor Diagnosed?
right and early diagnosis of any neoplasm is a prerequisite condition for ensuring a favorable medical prognosis and strategizing correct treatment approach . It is also important for tell apart between the benign and malignant tumor as both postulate different handling approach and both have different prognosis . Further , the clinical symptom presented by both the types are also different . A malignant nerve sheath tumour requires fast-growing treatment approach while being steel sheath tumor generally requires wait - and - watch glide path provide the mettle sheath tumor does not hampering sidereal day - to - day activities of the patient . Further , the phase of the nerve sheath tumor should be name as it will also assist in evaluating prognosis and treatment regimen .
Imaging Techniques – It is one of the most powerful technique for diagnosing any lesion or tumor in the body include nerve sheath tumor . These imaging techniques admit Computed Tomography scan , Magnetic Resonance Imaging and Ultrasonography . Out of these , MRI is said to the most effective symptomatic method acting for nerve sheath tumor . The tomography proficiency helps in position and extent of the tumor . Although sonography is not a very reliable technique in nerve sheath tumour but when couple with other technique , it gives accurate answer and helps in severalize between the nerve sheath tumor and the swollen lymph guest .
Physical Examination – A elaborated skin or neurological test is done by the physician at the initial stage to exclude the presence of other diseases with similar symptoms . Study of accomplished medical history of the affected role also help in diagnosing of nerve sheath tumor . The comportment of lumps or mass is also try out during physical testing .
Electromyogram – It is the diagnostic tool that evaluates the bodily function of muscles . As the nerve sheath neoplasm compresses the face , the electrical conduction of the peripheral mettle gets compromised induce reduction of the muscular activity . In this proficiency , the needle are tie to the muscleman and the muscular activity is calculated by the legal document .
Blood And Urine Tests – Although not a conclusive method for diagnosing the mettle sheath tumor , presence of some chemical substance in the roue may assist in judge abnormality inside the body . Identification of potential biomarker for tumor is done through these lab testing .
Immunohistochemical Analysis – In recent time , this technique has paved is style in the diagnosis of malignant neoplastic disease by key out various proteins , presence of which may point the existence of cancer . The immunochemical visibility of the nerve sheath tumor such as SOX10 , SOX2 , and neurofibromin are assessed .
Myelography – In affected role of nerve sheath tumors , who are unable to undergo the MRI , CT myelography is a desire choice . It requires lumbar puncture and the contrasting agent is introduce . It is a technique wherein the real time Adam - ray is lead . It is used to examine the nervus and concern tissues with the help of counterpoint federal agent .
Biopsy – Biopsy is an encroaching procedure wherein the tissue is claim from the nerve sheath neoplasm and is try out under the microscope for any cellular irregularity . It is an important proficiency to confirm the present of malignant tumor . If the whole moved tissue is removed , then it is termed as excisional biopsy while incisional biopsy involves the extraction of a part of moved tissue . Another biopsy method acting is pith biopsy or needle biopsy wherein a needle is used to excerpt the sampling for analysis .
Nerve Conduction Study – While EMG involves the analysis of muscleman enduringness , nerve conduction testing is done to identify the speed of the nerve impulse bring forth in the nervous system .
Conclusion
Various diagnostic techniques are used for diagnose the cheek sheath tumour . These demand imaging techniques such asCT scan , MRIand sonography , nerve conduction test , forcible examination , biopsy , myelography , electromyogram , bloodline test and immunohistochemical analytic thinking .
