RESUMO

ABSTRACT: There is no practical predictive model for the diagnosis of gastrointestinal stromal tumors (GISTs). To establish a practical predictive model for the diagnosis of subepithelial lesions in the stomach, we reviewed patients with GISTs (n = 89), schwannomas (n = 7), and leiomyomas (n = 28).The tumor was more frequently found along the gastric cardia in the leiomyoma group (57.1%) than in the GIST/schwannoma group (2.1%, P < .01). Contrast enhancement (57.3% vs 0%, P < .01) and intra-tumoral necrosis (34.4% vs 0.0%, P < .01) were more frequently observed in the GIST/schwannoma group than in the leiomyoma group. On endoscopic ultrasonography, 58.3% of GISTs/schwannomas showed uneven echogenicity, whereas the echogenicity was uneven in 21.4% of leiomyomas (P < .01). There were no differences between the tumor color and the presence or absence of ulcer formation, tumor bleeding, irregularity of the tumor margin, cystic spaces, and hyperechoic spots between the 2 groups. Based on these results, we developed a 2-step diagnostic algorithm for GISTs/schwannomas. The first step comprises 1 endoscopic feature: a cardiac or non-cardiac location. Tumors with a cardiac location were judged as leiomyomas and those with a non-cardiac location were judged as GISTs/schwannomas, with 96.9% sensitivity and 57.1% specificity for GIST/schwannoma diagnosis. The second step comprises a combination of endoscopic (non-cardiac location), radiologic (positive contrast enhancement and intra-tumoral necrosis), and endosonographic (uneven echogenicity) features for a total of 4 points. We assigned 1 point to each feature. Tumors with scores of 2 to 4 were judged as GISTs/schwannomas, with 81.3% sensitivity and 92.9% specificity for GIST/schwannoma diagnosis.Our predictive model will be a practical guide for the management of gastric subepithelial lesions.

RESUMO

ABSTRACT: Skull base vagal nerve schwannoma (VNS) is relatively uncommon and poses a challenge to surgeons. Although schwannomas are benign and slowly growing neoplasms arising from Schwann cells, they may cause significant dysfunction by causing the surrounding structures compression or infiltrating vital structures such as the skull base, the orbit, and the cranial nerves. These tumors are resistant to radiotherapy and chemotherapy. Complete surgical removal is the optimal treatment modality, with recurrence being rare. The authors report a case of a 58-year-old man with an extensive VNS involving the left jugular foramen and parapharyngeal space. The clinical presentation, surgical management, and outcomes of VNS are discussed.

RESUMO

SIGNIFICANCE: Facial nerve schwannomas are rare tumors that are usually benign and relatively slow in their progression. Common symptoms include facial neuropathy, auditory deficiencies, and parotid masses. Because of slow progression, symptoms are often present for over a year before an appropriate diagnosis is made. PURPOSE: The purpose of this study was to present a case in which comprehensive dry eye assessments and management led to diagnosis of facial nerve shwannoma in a patient who had no presenting symptoms of auditory deficiencies or facial weakness. CASE REPORT: A 36-year-old woman presented for a contact lens examination with concerns of progressively worsening symptoms of irritation and dryness in her right eye that began 6 months earlier. Dry eye assessment visits and management strategies were implemented. Although this regimen was initially successful, symptoms returned after 7 months. At this visit, a new finding of incomplete blink in her right eye was manifested. Further in-office assessments revealed a weakened right orbicularis oculi and right frontalis muscle. These findings, combined with patient risk factors and no history of trauma, prompted MRI of the seventh nerve. Imaging revealed the presence of seventh nerve schwannoma, the location of which correlated with the geniculate ganglion and greater superficial petrosal nerve. This patient was later referred to a neurosurgeon, who assessed the risks and benefits of schwannoma removal. It was decided that the risks of the surgery outweighed the benefits, and regular MRI was scheduled for monitoring purposes. Appropriate management of the patient's chronic dry eye disease continues. CONCLUSIONS: Facial nerve schwannomas can and do present with no presenting subjective facial neuropathy symptoms aside from mild unilateral dry eye and can be detected with comprehensive dry eye management. This case may contribute to future minor adjustments in clinical practice guidelines for asymmetric dry eye assessments.

RESUMO

BACKGROUND AND AIMS: Multinodular/plexiform schwannomas and neurofibromas of major nerves are rare: before surgery, differential diagnosis among these two uncommon variants is challenging. For both forms, surgical removal is recommended in case of progressive growth and worsening of neurological symptoms. Surgery has a higher risk of neurological damage than conventional schwannomas or neurofibromas. In literature, a comparison among these rare tumors is usually limited to the pathological aspect while specific surgical and clinical management indications are lacking. Cutaneous tumors of both forms arising from terminal peripheral nerves' branches might be treated by plastic surgeons while tumors of major nerves remain under neurosurgical competence. Here we report our recent neurosurgical experience on the matter, to furnish useful suggestions for the management of these tumors. METHOD: We analyzed the clinical, radiological, and pathological data in a consecutive case series of plexiform/multinodular nerve tumors operated at our institution in the last five years. RESULTS: In our series, neurofibroma type of plexiform tumors was more frequent than schwannoma type: two sporadic plexiform-multinodular schwannomas (patients 1, and 5) and three multinodular/plexiform Neurofibromatosis familial (Neurofibromatosis 1 / NF-1) (patients 2, 3, and 4). Surgery was complex when major nerves were involved. The early outcome appeared mostly related to the pre-surgical neurological conditions and histological grading. INTERPRETATION: Although sharing some features, multinodular-plexiform schwannomas and neurofibromas have consistent differences from the clinical, surgical and pathological points of view.

RESUMO

A 33-year-old woman was diagnosed with right recurrent laryngeal nerve (RLN) schwannoma. She presented with a long history of hoarseness, and only recently developed dysphagia. On physical examination, a mass was observed over the right cervical level IV. Endoscopic examination of the larynx showed that she had right unilateral vocal cord palsy. She successfully underwent transcervical resection of the tumour followed by injection laryngoplasty. This study discusses the presentation of the tumour, radiological findings, our working diagnosis and treatment options of RLN schwannoma.

RESUMO

Schwannomas are typically benign tumours of the peripheral nerves. However, they seldom arise from the obturator nerve. We report a case of an uncommon swelling (2.5 × 3.5 cm) in a 65-year-old male cadaver, found during a routine dissection session for first Bachelor of Medicine and Surgery students in the Department of Anatomy, Kasturba Medical College, Manipal, India, in 2019. It was seen originating from the left obturator nerve in the pelvis at the level of the sacral promontory. Histopathological investigation revealed a schwannoma. The hypocellular tumour was arranged in a sweeping fascicle pattern with patches of myxoid degeneration. Obturator schwannomas, though rare, can exist in cadavers, as seen in the present case. Hence, it should be considered as a differential diagnosis for clinical cases of pelvic masses and eliminated only after thorough radiological examination. Knowledge about the existence of such schwannomas is therefore essential.

RESUMO

BACKGROUND Neurofibromatosis (NF) is categorized into 3 diseases: neurofibromatosis type 1, type 2, and schwannoma. NF2 is associated with a mutation in gene 22q11.2. It is present in about 1/25 000 to 33 000 births, and it is passed in an autosomal dominant fashion. Diagnosis is made based on clinical and radiological features. A few clinical features have been characterized and included in the Manchester criteria. A few neurofibromatosis type 2 patients have been diagnosed with over 25 cervical lesions. We report a case of an intradural extramedullary cervical lesion in a patient later diagnosed with neurofibromatosis type 2. CASE REPORT The patient was 30-year-old man admitted through the emergency unit, presenting with gradual onset and progressive spastic quadriparesis of 6 months duration. An MRI spine showed intradural extramedullary masses in the right side of C4 and left side of C6. He underwent cervical intradural excision of 2 masses under general anesthesia with neuromonitoring. The tumor was sent to histopathology and reported as neurofibromatosis 2. CONCLUSIONS Neurofibromatosis is a common entity, but the diagnosis of a cervical mass is judicious to avoid any misfortune in neurological function. It requires a multidisciplinary approach and screening modalities.

RESUMO

Intraosseous schwannoma is extremely rare that it is not often considered among differential diagnosis for an osteolytic lesion, especially in long bones of the extremities. Amounting to less than 0.2% of all primary bone tumours and less than 200 cases reported so far, with only 3 cases involving the humerus, we hereby report the fourth case. In addition to its rarity, this was the only case of an intraosseous schwannoma involving the humerus bone which presented with a pathological fracture in a 45-year-old woman after sustaining a trivial trauma. Radiological examination revealed a geographic type of osteolytic lesion in distal shaft region of the left humerus. Only a histopathological examination helped in revealing and confirming the diagnosis of an intraosseous schwannoma. Treatment of the tumour with complete excision with bone graft reconstruction and osteosynthesis yields good results with very low risk of recurrence.

RESUMO

Subungual schwannoma is quite rare and often causes nail deformity and difficulty in wearing shoes. Complete tumor excision is the treatment of choice, and we advocate that restoring the nail appearance should be considered at the same time. We present the case of 43-year-old man with a big toe subungual schwannoma. We designed a zigzag incision method to excise the tumor and also corrected nail-bed deformity. The patient had a smooth recovery, and the nail plate regrew with a good appearance.

RESUMO

BACKGROUND AND OBJECTIVE: Vestibular schwannoma is a benign tumour that originates in the eighth cranial nerve. It is termed intralabyrinthine schwannoma (ILS) when it develops in the inner ear, this being a rare origin. We present our experience in the management of three patients with ILS. MATERIALS AND METHODS: The results of tumour excision and cochlear implantation were evaluated in three patients with ILS: two intracochlear schwannomas (ICS) and one intravestibular schwannoma (IVS). RESULTS: Prior to surgery, all patients presented progressive sensorineural hearing loss and tinnitus. Complete tumour resection and cochlear implantation was possible in all patients, with favourable hearing rehabilitation. CONCLUSIONS: The therapeutic approach will depend on tumour size, growth rate, degree of hearing loss and presence of vestibular symptoms. Cochlear implantation (CI) in patients with ILS is possible when the cochlear nerve is present and functional. CI in patients, whether or not preceded by tumour excision, is an option with good hearing results in selected patients.

RESUMO

BACKGROUND AND PURPOSE: Accurate differentiation of paragangliomas and schwannomas in the jugular foramen has important clinical implications because treatment strategies may vary but differentiation is not always straightforward with conventional imaging. Our aim was to evaluate the accuracy of both qualitative and quantitative metrics derived from dynamic contrast-enhanced MR imaging using golden-angle radial sparse parallel MR imaging to differentiate paragangliomas and schwannomas in the jugular foramen. MATERIALS AND METHODS: A retrospective study of imaging data was performed on patients (n = 30) undergoing MR imaging for jugular foramen masses with the golden-angle radial sparse parallel MR imaging technique. Imaging data were postprocessed to obtain time-intensity curves and quantitative parameters. Data were normalized to the dural venous sinus for relevant parameters and analyzed for statistical significance using a Student t test. A univariate logistic model was created with a binary output, paraganglioma or schwannoma, using a wash-in rate as a variable. Additionally, lesions were clustered on the basis of the wash-in rate and washout rate using a 3-nearest neighbors method. RESULTS: There were 22 paragangliomas and 8 schwannomas. All paragangliomas demonstrated a type 3 time-intensity curve, and all schwannomas demonstrated a type 1 time-intensity curve. There was a statistically significant difference between paragangliomas and schwannomas when comparing their values for area under the curve, peak enhancement, wash-in rate, and washout rate. A univariate logistic model with a binary output (paraganglioma or schwannoma) using wash-in rate as a variable was able to correctly predict all observed lesions (P < .001). All 30 lesions were classified correctly by using a 3-nearest neighbors method. CONCLUSIONS: Paragangliomas at the jugular foramen can be reliably differentiated from schwannomas using golden-angle radial sparse parallel MR imaging-dynamic contrast-enhanced imaging when imaging characteristics cannot suffice.

RESUMO

ABSTRACT: Melanotic schwannoma is an uncommon nerve sheath neoplasm. Only 10% of melanotic schwannoma are malignant whereas metastases from melanotic schwannoma are much less common. Hereby we present FDG PET/CT findings of recurrent left retroperitoneal melanotic schwannoma with widespread metastases in a 50-year-old man.

RESUMO

BACKGROUND: In this report, we describe the first case in literature of a patient with multiple schwannomas of the marginal mandibular branch of the facial nerve. CASE PRESENTATION: A Caucasian patient presented with a sudden onset of left lower facial nerve palsy House-Brackmann score III for 1 month. Computed tomography imaging was performed to exclude a cerebral event and revealed multiple tumors within the left parotid gland. Duplex ultrasound and magnetic resonance imaging scans delineated multiple, hypoechoic tumors, round in shape and well defined without a hilar structure along the left mandible. For histological verification, a left-side partial parotidectomy and extirpation of an intraparotideal node was performed with use of a nerve-integrity monitor. Histomorphological analysis of the resected tissue revealed a benign schwannoma. Facial nerve function remained unchanged since the operation. The size of the nonresected tumors is currently monitored regularly by ultrasonography. Fibromatosis has been excluded. CONCLUSIONS: If multiple tumors occur in the parotid gland and the angle of the jaw, schwannomas need to be considered as a differential diagnosis. To plan the right diagnostic surgical intervention and prevent nerve damage, a thorough ultrasound examination is essential in preoperative diagnostic work-up for any suspicious lesion of the parotid gland and jaw region.

RESUMO

Background and Objectives: Retroperitoneal schwannoma is a very rare case of schwannoma which commonly occurs in the other part of the body. However, it is difficult to distinguish schwannoma from other tumors before pathological examination because they do not show specific characteristics on imaging study such as ultrasound, computed tomography (CT), and magnetic resonance image (MRI). Case summary: A 60-year-old male showed a retroperitoneal cystic tumor which is found incidentally during evaluation of coexisted bladder tumor. Neurogenic tumor was suspicious for the retroperitoneal tumor through pre-operative imaging study. Finally, a schwannoma was diagnosed by immunohistochemical examination after complete surgical excision laparoscopically. Conclusion: As imaging technology is developed, there may be more chances to differentiate schwannoma from other neoplasm. However, still surgical resection and histopathological examination is feasible for diagnosis of schwannoma.

RESUMO

Peripheral nerve injuries are a common condition in which a nerve is damaged, affecting more than one million people every year. There are still no efficient therapeutic treatments for these injuries. Artificial scaffolds can offer new opportunities for nerve regeneration applications; in this framework, chitosan is emerging as a promising biomaterial. Here, we set up a simple and effective method for the production of micro-structured chitosan films by solvent casting, with high fidelity in the micro-pattern reproducibility. Three types of chitosan directional micro-grooved patterns, presenting different levels of symmetricity, were developed for application in nerve regenerative medicine: gratings (GR), isosceles triangles (ISO) and scalene triangles (SCA). The directional patterns were tested with a Schwann cell line. The most asymmetric topography (SCA), although it polarized the cell shaping less efficiently, promoted higher cell proliferation and a faster cell migration, both individually and collectively, with a higher directional persistence of motion. Overall, the use of micro-structured asymmetrical directional topographies may be exploited to enhance the nerve regeneration process mediated by chitosan scaffolds.

RESUMO

Vestibular schwannoma is a known cause of progressive sensorineural hearing loss. Treatment options include observation, radiation therapy and surgical resection. Cerebrospinal fluid (CSF) fistula is a known postsurgical complication that can lead to CSF otorrhoea, rhinorrhoea or CSF leakage from the surgical wound. We present a case report of a patient who underwent vestibular schwannoma resection and postoperatively developed CSF rhinorrhoea, which was refractory to multiple attempts at surgical repair. This was successfully treated under endoscopic and fluoroscopic guidance using a biliary cytology brush to disrupt the surface of the eustachian tube followed by injection of n-Butyl cyanoacrylate.

RESUMO

BACKGROUND: Total rhinectomy is an invasive procedure that significantly impairs the intranasal turbulence, humidification and heating of inspired air. The use of uvulopalatopharyngoplasty for the treatment of sleep-disordered breathing disorders such as primary snoring and obstructive sleep apnoea has diminished over the past years because of the emergence of less invasive procedures and alternative therapeutic options. This clinical record presents the treatment of a long-term side effect of total rhinectomy using uvulopalatopharyngoplasty. CASE REPORT: In 1997, a 62-year-old male underwent total rhinectomy for a nasal schwannoma, followed by rehabilitation with a nasal prosthesis. Twenty-one years later, he presented with severe complaints of nasal blockage and breathing difficulties during both daytime and night-time. Clinical examination revealed no major anomalies besides significant velopharyngeal narrowing. Thus, in 2019, uvulopalatopharyngoplasty was performed to re-establish velopharyngeal patency. Hereafter, the symptoms of nasal blockage disappeared, resulting in an improved quality of life. CONCLUSION: Uvulopalatopharyngoplasty may prove useful to treat selected patients with daytime breathing difficulties due to velopharyngeal narrowing.
