Primary intra and extradural solitary fibrous tumor/hemangiopericytoma of thoracic spine with paravertebral intrathoracic spread: Case report and rev…
2020
Abstract Solitary fibrous tumors/hemangiopericytomas (SFTs/HPCs), constitute 1% of all CNS tumors. Spinal SFTs/HPCs are extremely rare. To date, few retrospective studies and case reports of primary spinal SFTs/HPCs have been published in the literature. We report clinical and radiological presentation, surgical treatment, and post-operative outcome at three years follow-up of a rare case of primary spinal intra and extradural SFT/HPC of thoracic spine with dumbbell shaped paravertebral intrathoracic spread and multidirectional erosion of the bone. A 73-year-old female presented with progressive lower limbs weakness and hypoesthesia below the rib cage. MRI showed an irregular isointense T5-…
Akustikusneurinom als Ursache einer progredienten kindlichen Hörstörung
2003
Background: Neurinomas of the vestibulocochlear nerve unrelated to neurofibromatosis in children are extremely rare. Only 20 cases in children under the age of 16 are reported in the literature. Progressive unilateral hearing loss, tinnitus, vertigo and neurological deficits due to cranial nerve or brainstem compression are clinical signs. Patient and Results: We report on the case of a 12-years-old girl with an unilateral hearing loss, progressing to total deafness. Otoacoustic emissions were normal. In the MRI a large cerebellopontine angle tumor was found, identified as schwannoma of the vestibulocochlear nerve. Conclusions: The importance of MR Imaging in children with progressive unila…
Thoracic dumbbell spinal chordoma mimicking a schwannoma
2021
Background: Epidural dumbbell-shaped chordomas are localized slow growing, and malignant/aggressive neoplasms. Here, we present a 62-year-old male with a T3-T4 dumbbell-shaped chordoma and reviewed the appropriate literature. Case Description: A 62-year-old male presented with a three-month history of thoracic pain. When the thoracolumbar magnetic resonance (MR) showed a T3-T4 dumbbell-shaped intracanalicular/extradural tumor, he underwent tumor removal. After the histological examination proved the lesion was a spinal chordoma, he underwent a secondary radical transthoracic tumor resection. Postoperatively, the patient was able to walk without assistance, and at 6-month follow-up, was neu…
Schwannoma of the larynx. Case report
2005
Neuretogenous tumours of the larynx are extremely uncommon. We present a case of schwannoma of the larynx and review pertinent data in the literature. Laryngeal schwannoma was discovered in a 80-year-old woman who complained of persistent dysphonia. The histological findings leading to diagnosis together with the therapeutic surgical procedure are described. There was no postoperative complication and functional outcome was excellent at six months follow-up, demonstrating that conservative surgery is required for this type of disease. Conservative surgery provides excellent results. Although very rare, schwannoma should be taken into consideration in the differential diagnosis of any laryng…
Manejo de schwannoma vestibular con radiaciones : experiencia del IVO
2013
A partir de la década de los 70, nace la radiocirugía (RC) como tratamiento alternativo a la cirugía convencional en el tratamiento de los schwannomas vestibulares(SV). Poco a poco dicha técnica, ha ido desbancando a la microcirugía alcanzando cifras del 58 % de tratamientos de RC frente a la cirugía convencional. En el presente estudio analizamos el resultado de 167 tumores tratados con radiaciones (bien con dosis única (RC) o con dosis fraccionada, RT Estereotáctica Fraccionada (RTEF), determinando el control local y las complicaciones como tratamiento del SV. Analizamos los resultados en función de la tecnología utilizada para tratarlos, bien colimadores cilíndricos o bien micromutilámin…
