BACKGROUND: Gamma Knife radiosurgery (GKRS) allows for the treatment of intracranial tumors with a high degree of dose conformality and precision. There are, however, certain situations wherein the dose conformality of GKRS is desired, but single session treatment is contraindicated. In these situations, a traditional pin-based GKRS head frame cannot be used, as it precludes fractionated treatment. OBJECTIVE: To report our experience in treating patients with fractionated GKRS using a relocatable, noninvasive immobilization system...

BACKGROUND: Nowadays, there is a general trend in vestibular schwannoma (VS) surgery favoring near-total or subtotal tumor resection (NTR/STR) with facial nerve (FN) function preservation rather than gross total resection (GTR) with high risk of FN damage. METHODS: The surgical technique of FN sparing in large VS includes patient-tailored image-guided craniotomy, continuous intraoperative neurophysiological monitoring (INM), intracapsular wide tumor debulking, and only final extracapsular dissection with FN course identification and brainstem decompression...

OBJECTIVE: Radiation-induced benign peripheral nerve sheath tumors are uncommon late complications of irradiation. We conducted the largest systematic review of individual patient data. METHODS: We performed a systematic search of PubMed databases, and compiled a comprehensive literature review. Kaplan-Meier analysis was used to investigate survival, and statistical significance was assessed using a log-rank test. RESULTS: We analyzed 40 cases of radiation-induced benign peripheral nerve sheath tumors...

BACKGROUND: Hybrid peripheral nerve sheath tumors (PNSTs) have been recognized recently and were first included in the 4th edition of World Health Organization (WHO) Classification of Tumors of Soft tissue and Bone, published in 2013. These tumors show combined features of more than one type of conventional benign peripheral nerve sheath tumors. The most common combinations are those of schwannoma/perineurioma followed by combinations of neurofibroma/schwannoma and neurofibroma/perineurioma...

OBJECTIVE The management of vestibular schwannoma (VS) remains controversial. One commonly cited advantage of microsurgery over other treatment modalities is that tumor removal provides the greatest chance of long-term cure. However, there are very few publications with long-term follow-up to support this assertion. The purpose of the current study is to report the very long-term risk of recurrence among a large historical cohort of patients who underwent microsurgical resection. METHODS The authors retrospectively reviewed the medical records of patients who had undergone primary microsurgical resection of unilateral VS via a retrosigmoid approach performed by a single neurosurgeon-neurotologist team between January 1980 and December 1999...

The aim of the present study was to identify computed tomography (CT) features to assist in differentiating gastrointestinal schwannomas from gastrointestinal stromal tumors (GISTs). CT images of gastrointestinal schwannomas (n=15) and GISTs (n=50) were analyzed. The absolute CT values of tumor/aorta during plain scan/arterial phase/venous phase were recorded as tumor plain scan (Tp)/aorta plain scan (Ap), tumor arterial phase (Ta)/aorta arterial phase (Aa) and tumor venous phase (Tv)/aorta venous phase (Av), respectively, and normalized CT values of the three phases were calculated as Sp=Tp/Ap, Sa=Ta/Aa and Sv=Tv/Av, respectively...

Laryngeal schwannomas are extremely uncommon. We present a case of bulky supraglottic schwannoma with involvement of the preepiglottic and superior paraglottic spaces. Clinical findings, computed tomography and magnetic resonance images are presented. These characteristics are typical, however not specific to schwannomas. For definitive diagnosis, histology and immunohistochemistry are necessary. We present an external mini-invasive approach that allowed us to both obtain diagnosis and provide definitive treatment for this kind of voluminous laryngeal tumour...

The incidence of vertebral artery (VA) injury (VAI) in posterior approach tumor resection surgery is extremely rare, but it can lead to serious complication. In this case, a 57-year-old man underwent surgery for resection of the tumor involving left epidural space and neural foramen at C2-3 level. Iatrogenic VAI occurred suddenly during tumor resection procedure using pituitary forceps. Immediate local hemostasis and maintaining of perfusion for reducing the risk of posterior circulation ischemia were performed...

An increasing number of congenital and infantile sarcomas displaying a primitive, monomorphic spindle cell phenotype have been characterized to harbor recurrent gene fusions, including infantile fibrosarcoma and congenital spindle cell rhabdomyosarcoma. Here we report an unusual spindle cell sarcoma presenting as a large and infiltrative pelvic soft tissue mass in a 4-month-old girl, which revealed a novel TFG-MET gene fusion by whole transcriptome RNA sequencing. The tumor resembled the morphology of an infantile fibrosarcoma with both fascicular and patternless growth, however, it expressed strong S100 protein immunoreactivity, while lacking SOX10 staining and retaining H3K27me3 expression...

BACKGROUND: Malignant peripheral nerve sheath tumor (MPNST) arising in benign schwannoma with multiple intraosseous spinal metastasis is extremely rare, having a highly aggressive progression and poor prognosis. In such cases, the malignant cells of MPNST usually have an epithelioid morphology. Here, the authors present a very rare case of spindle cell type MPNST arising in benign schwannoma. CASE: A 47-year-old woman had a history of wide marginal excision of right buttock spindle cell sarcoma previously...

Gastric schwannomas (GSs) and gastrointestinal stromal tumors (GSTs) are grossly similar submucosal neoplasms with different prognoses. We explored the value of spectral computed tomography (CT) to distinguish between them. METHODS: Patients diagnosed with GS or GST at Lanzhou University Second Hospital, China, between May 2013 and June 2015 were included retrospectively. The subjects underwent spectral CT examination before surgery and had histologically confirmed diagnosis of GS or GST...

Metastatic neuroendocrine carcinoma of unknown origin is a rare condition, usually presenting with lesions in the liver and/or lung. We present the first reported case of a metastatic neuroendocrine carcinoma of unknown origin arising in the femoral nerve sheath. MRI demonstrated what was thought to be a schwannoma in the left femoral nerve sheath in the proximal femoral triangle, immediately inferior to the anterior inferior iliac spine. At the time of operation, the tumour capsule was invading surrounding tissue as well as three trunks of the femoral nerve...
