Management of the cervical esophagus and hypofarinx perforations complicating anterior cervical spine surgery.

Study Design. Five cases of esophageal or pharyngeal perforation diagnosed during or after anterior cervical spine surgery are presented. Objective. To outline a protocol for the early diagnosis and treatment of iatrogenic pharyngoesophageal perforations. Summary of Background Data. Pharyngoesophageal perforations after anterior cervical spine surgery are uncommon or rarely reported complications. They may have serious functional consequences, including death, if they are not diagnosed promptly and treated effectively. These potentially fatal conditions require a surgical and medical therapy. Methods. Clinical course, diagnostic tools and guidelines for the management of five patients presenting esophagopharingeal perforations are illustrated. Results. These five cases resulted in definitive healing of the laceration without functional consequences. Conclusion. We believe that awareness of these complications and their causes, prompt recognition of the symptoms and immediate and multimodality therapies are essential tools to achieve successful results.

Multicentric glioma: our experience in 25 patients and critical review of the literature

Multicentric gliomas are interesting and well-recognised entities with a yet unknown rate of occurrence. Single cases or small series are reported in the literature accessible to us, and we think this is the first large series describing true multicentric gliomas. We reviewed 25 patients selected according to the criteria defined by Batzdorf and Malamud. Multicentricity was found in 2% of patients with malignant gliomas. Longer survival was observed in patients who underwent surgical excision of the multicentric lesions. Multicentric tumours are rare clinical entities. Our data suggest that they should be surgically removed whenever possible, and histopathologic examination of the lesions is always advisable if they are located in sites inaccessible to surgery. Stereotactic biopsy represents a safe and satisfactory method for achieving sure diagnosis.

Intrameningioma metastasis as first clinical manifestation of occult primary breast carcinoma

Metastasis from extracranial tumor into an intracranial primary tumor is an uncommon event. A predominant tendency of meningioma to be the host tumor for breast carcinoma has been found. In the current report, three cases of breast carcinoma metastatic to intracranial meningiomas are described. In our cases, metastasis in meningioma was the first clinical manifestation of the occult primitive breast carcinoma. We review widely the literature concerning such rare occurrences and discuss all the postulated pathogenetic mechanisms. There are few cases reported in the literature on resonance magnetic imaging of metastatic carcinoma in meningioma. Two of our patients have been studied by MRI, but we do not find predictive radiological finding of this particular association.

Solitary fibrous tumors of the meninges: Report of four cases and literature review

Central nervous system solitary fibrous tumors are a new pathological entity. To our knowledge, only 60 meningeal solitary fibrous tumors both in the spinal cord and in the brain have been described in the literature. The 56 previously reported cases of meningeal solitary fibrous tumors are critically reviewed. In addition, we report four new cases of solitary fibrous tumors of the meninges. There is a slight male prepoderance. Meningeal solitary fibrous tumors show a tendency to arise in the posterior fossa (26%) and spine (25%). The treatment was mainly total surgical excision. Radiotherapy was given only to four patients with tumors involving the cerebral parenchyma. Sporadic cases of recurrence and distant metastasis have been reported. The prognosis of meningeal solitary fibrous tumors is still unknown because the follow-up of the reported cases is short. It is probable that cases of solitary fibrous tumors of the meninges have been misdiagnosed as other tumors in the past. The best management of these tumors seems to be total surgical excision whenever possible. It is important that every new case of meningeal SFT be reported to throw light on this particular tumor and to affirm its status as a clinicopathological entity.

Intracranial Meningiomas in Children: Report of 27 New Cases and Critical Analysis of 440 Cases Reported in the Literature

We accumulated 440 cases of intracranial meningiomas in patients under 16 years of age, and another 27 personal. This review confirms the existence of specific clinical features of spontaneous and radiation-induced meningioma in children. In addition, we discuss various points that suggest a more aggressive behavior of meningiomas in children than in adults. (J Child Neurol 2006;21:31—36).

Management of acute cerebellar infarction: one institution's experience

OBJECTIVEThe management of cerebellar infarctions is controversial. The aim of this study was to determine which patients require surgical treatment and which surgical procedure should be performed when a patient with a cerebellar infarction exhibits progressive neurological deterioration. METHODSA total of 44 patients (24 male and 20 female patients; average age, 56 yr) were treated at our institution for cerebellar infarctions in the past 8 years. Twenty-five patients received conservative treatment; two patients who were deeply comatose received no treatment. The remaining 17 patients underwent emergency surgery. Of those 17 patients, 8 underwent external ventricular drainage alone, 5 underwent external ventricular drainage as the first treatment plus secondary suboccipital craniectomy, and 4 underwent suboccipital craniectomy, with removal of necrotic tissue, as the first treatment. RESULTSOf the 25 conservatively treated patients, 20 experienced good outcomes, 4 experienced moderate outcomes, and 1 died as a result of pulmonary embolism. Of the 17 surgically treated patients, 10 experienced good functional recoveries (7 treated with external ventricular drainage only and 3 treated with drainage followed by suboccipital craniectomy) and 3 survived with mild neurological deficits (one patient underwent ventriculostomy, one suboccipital craniectomy plus external ventricular drainage, and one suboccipital craniectomy only). The overall mortality rate was 13.6% (6 of 44 patients). CONCLUSIONFor patients with worsening levels of consciousness and radiologically evident ventricular enlargement, we recommend external ventricular drainage. We reserve surgical resection of necrotic tissue for patients whose clinical status worsens despite ventriculostomy, those for whom worsening is accompanied by signs of brainstem compression, and those with tight posterior fossae.

Gliosarcomas: Analysis of 11 cases do two subtypes exist?

SummaryThere are conflicting reports regarding gliosarcomas. The goal of this study is to examine clinical, radiological, surgical and therapeutic aspects of 11 patients with gliosarcoma. Between 1993 and 2001, 11 patients with cerebral gliosarcoma were treated at our Institute. Ten patients underwent surgery and one patient had stereotactic biopsy. Four patients received whole brain radiotherapy with 60Co, five underwent radiotherapy with LINAC extended 2 cm beyond the edema margins. One patient refused any additional treatment after surgery and one patient was not treated postoperatively for poor clinical conditions (KPS 40). Chemotherapy (temozolomide) was administered to four patients. Four patients had a prevalence of sarcomatous component that corresponded to surgical and radiological aspects similar to meningioma while six patients showed a prevalence of gliomatous component and radiological and surgical aspects similar to those of glioblastomas. Surgical resection was total in six and subtotal in four patients. Patients with prevalent sarcomatous component showed median survival time more prolonged than patients with prevalent gliomatous component (71 ± 6 weeks vs. 63 ± 6; P=0.0417). Moreover, the survival rate differed in relation to the therapy: patients treated with multimodality therapy (surgery, radiotherapy and chemotherapy) had a longer survival time than patients treated in single or bimodality. Despite prognosis of gliosarcomas remains poor, a multidisciplinary approach (surgery, radiotherapy and chemotherapy) seems to be associated with slight more prolonged survival times.

Multilevel Oblique Corpectomy Without Fusion: Our Experience in 48 Patients

Study Design. The authors provide their results in performing multilevel oblique corpectomy for degenerative spondylotic myelopathy in 48 patients. Objective. To demonstrate the efficacy and safety of the multilevel oblique corpectomy when applied in selected cases. Summary of Background Data. The technique of multilevel oblique corporectomies for treatment of cervical spondylogenetic myeloradiculopathies allows anterolateral access to the cervical spine so that the spinal canal and conjugate foramen can be widened at more than one level, without the need for vertebral stabilization. Methods. During a 7-year period, multilevel oblique corpectomy was performed in 48 consecutive patients for degenerative spondylotic myelopathy. The outcomes were analyzed according to the Japanese Orthopaedic Association classification modified to Western customs, and according to Nurick’s scale 1 month, 1 year, and 2 years after surgery. Spinal stability was evaluated in all patients by plain radiograph films of the cervical spine, lateral views in flexion and extension, on discharge, 1 month and 1 year after operation. Results. Significant clinical improvement occurred in 29 patients with a complete functional recovery in 22; moderate improvement was achieved in 12 patients; neurological status remained stable in 5, and it worsened in 2. All patients showed spinal stability. Conclusions. Multilevel oblique corpectomy was found to be a safe technique that guarantees good results in terms of both regression of clinical symptoms and long-term spinal stability.

Traumatic Epidural Hematoma in Children

The purpose of this study was to investigate the characteristics of childhood acute epidural hematoma and to report our experience in recent years. A series of 35 patients below the age of 15 years treated for acute epidural hematoma at our institution between June 1991 and December 2000 was analyzed in detail. Pediatric epidural hematoma presents both age-related and atypical features when compared with epidural hematoma in adults. In selected cases, prompt surgical evacuation of the hematoma results in an excellent outcome. Outcomes seem to be directly related to the patients preoperative neurologic status and the presence of associated intracranial lesions. (J Child Neurol 2005;20:569—572).

Papillary glioneuronal tumor. Case report and literature review.

Objective and importancePapillary glioneuronal tumor is a recently described neoplasm composed of gliovascular pseudopapillae associated with intervening neuronal cells ranging from neurocytes to ganglion cells. This tumor is not currently included in the WHO classification of tumors of the central nervous system. We describe a new case of papillary glioneuronal tumor and analyze the data for a series of further 15 patients from international literature.Clinical presentationA 27-year-old man presented to us for generalized seizure. CT and MRI showed a cystic tumor with mural nodule in the left frontal lobe.InterventionFrontal craniotomy with gross total removal of the tumor was performed. Histopathological examination was positive for papillary glioneuronal tumor.ConclusionThe clinical, radiologic, and pathological features of our case are strikingly similar to those of the previous reported cases. A review of the literature disclosed only 15 other cases of these tumors.It is important that every new case of PGNT is reported to allow its recognition and classification.
