 Good morning everyone, I am Dr. G. Sai Sushant, 4th grad grader for any second year, first year in Calinga Institute of Medical Sciences at Bohnish. I am going to present a case report of spinal schwannomas, nausea tumors arise from strong cell precursors. This include neurofibromas, schwannomas and malignant peripheral nausea tumors. These are world health organization grade 1 tumors. They usually present as alterations and typically present in 4th or 5th decade of life. This is as earlier presentation and multiple lesions are usually associated with genetic symptoms such as neurofibromatosis 1, 2 and schwannomatosis. These are typically intradural and extramedulary although they may have extradural component and 70 percent of the cases are intradural extramedulary and 15 percent are completely extradural and 10 percent are transferominal. Intradural nausea tumors most commonly affect the lumbosecule region but few cases of cervical and thoracic tumors also have been reported. Intradural nausea tumors might be more common in lumbosecule region because of longer intradural segment of the quadruple spinal nerve root. 10 percent of the tumors arise as a nerve root, leave the turals at and become surrounded by the tural root's leave. These tumors therefore display both intradural and extradural component hence called the lumbar tumor. Coming to the case discussion here is that he had 8-year-old male, presented with symptoms of lower back pain radiating to the back of the hip and legs on both the sides associated with tingling sensation. The pain had been increasing in severity over the past few months and is not relieved on any pain medications. The neurological examination is completely normal without any sensor or motor deficit. The routine blood investigation and urinary investigations are within normal limits. So MRI, image, imaging revealed focal in intradural extramural relation measuring 14 into 11 mm at the level of D11 and D22 vertebrate. It is iso intense on T1 weighted image and mild hyper intense on T2 weighted image and it shows intense force contrast enhancement. The cell resection of the tumor was done along with laminate to me. The tumor is well encapsulated for main consistency and confined only to the extradural surface. Diagnosis of Sonoma was mainly by the characteristic astrological findings. Postoperatively patient showed gradual progressive improvement. So here is T1 weighted image and post-contrast image. This iso intense on T1 weighted image and it shows post-contrast enhancement. And here are the T2 weighted image and post-contrast image. It is mildly hyper intense on T2 weighted image and it shows post-contrast enhancement. It is hyper intense on T2 weighted images. So coming to the discussion of the Sonoma, these are benign soft tissue tumors that arrays run peripheral no-sheets throughout the body and are commonly encountered with type 2 neuropheromatosis. On the basis of age law school patterns, these are divided into antinatal type A and type B. The type 1 is highly cellular and demonstrates nuclear parasitic and vericabodies. Vericabodies refer to a stacked arrangement of two rows of elongated parasitic nuclei and alternating bands of cellular zones that are made up of tubular cytoplasmic processes of Schwann cells. Type 2 are more loosely organized cellular structures with areas of mixed somatos and cystic changes. It is often thought that type 2 represents degenerated type 1 tissue. These are tumor-storoplasm, use-for-masters, excentrically located with the in-all no and are contained within the epineurium. Coming to the MRI imaging features, these are ISO2 hyper intense on T1 weighted images and hyper intense on fluid sensitive sequences and often diffusely enhancing on contrast enhanced images. The tissue heterogeneity is relatively common and particularly the cystic degeneration. The heterogeneity has shown to be more common in antinatal type B, I mean correlate histologically more in antinatal type B than type A. So, the type 1 tumors are predominantly tend to be small and homogeneous whereas type 2 tend to be heterogeneous. The larger and more heterogeneous tumors also demonstrate increased hemocytic deposits and may be referred as ancient schwannomas. But the malignant degeneration of schwannomas is extremely rare. Conclusion, spinal schwannomas are overall rare and are included in differential for patients present with radiculopathy or myelopathy. MRI imaging allows characterization of spinal schwannoma which helps with the identification of the tumors which is vital when exploring surgical and adjuvant treatment options and patient management. So, these are my references. Thank you.
