The Central Cord Syndrome in Patients with Cervical Spinal Cord Tumors: A 19th-Century Vignette from (Karl) Julius Vogel (1814-1880).

Between 1830 and 1850, (Karl) Julius Vogel was one of the most important German pathologists. He received his doctorate in medicine in 1838 from the University of Munich and habilitation in pathology in 1840. In 1846, he moved to the University of Giessen as a full professor of pathology. From 1855, he taught special pathology and therapy at the University of Halle and became director of the internal clinic. Vogel and Heinrich Adolph Karl Dittmar were the first clinicians to describe the symptoms and pathologic findings of the central cord syndrome in a cervical spine tumor.

Radiation therapy for atypical and anaplastic meningiomas: an overview of current results and controversial issues.

Meningiomas are the most common intracranial tumors. Most meningiomas are WHO grade 1 tumors whereas less than one-quarter of all meningiomas are classified as atypical (WHO grade 2) and anaplastic (WHO grade 3) tumors, based on local invasiveness and cellular features of atypia. Surgical resection remains the cornerstone of meningioma therapy and represents the definitive treatment for the majority of patients; however, grade 2 and grade 3 meningiomas display more aggressive behavior and are difficult to treat. Several retrospective series have shown the efficacy and safety of postoperative adjuvant external beam radiation therapy (RT) for patients with atypical and anaplastic meningiomas. More recently, two phase II prospective trials by the Radiation Therapy Oncology Group (RTOG 0539) and the European Organisation for Research and Treatment of Cancer (EORTC 2042) have confirmed the potential benefits of fractionated RT for patients with intermediate and high-risk meningiomas; however, several issues remain a matter of debate. Controversial topics include the timing of radiation treatment in patients with totally resected atypical meningiomas, the optimal radiation technique, dose and fractionation, and treatment planning/target delineation. Ongoing randomized trials are evaluating the efficacy of early adjuvant RT over observation in patients undergoing gross total resection.

Multilevel Postoperative Cervical Epidural Hematoma: Complete Removal Through Catheter Drainage of the Unexposed Blood Collection.

BACKGROUND: Postoperative spinal epidural hematoma is a rare complication of anterior cervical discectomy and fusion. This condition may rapidly produce severe neurologic deficits, often requiring a prompt surgical decompression. A multilevel extension of the epidural bleeding has been rarely described after anterior cervical procedures. In such cases, the choice of the most suitable surgical approach may be challenging. Herein, we describe an effective surgical decompression of a C2-T1 ventral epidural hematoma following anterior cervical discectomy and fusion at the C5-C6 level. METHODS: By reopening the previous approach, the C5-C6 intersomatic cage was removed and the surgical field inspected for bleeding. After removal of the spinal epidural hematoma at this level, a lumbar external drainage catheter was inserted into the epidural space to perform multiple irrigations with saline solution until the washing fluid was clear. RESULTS: Immediate postoperative cervical computed tomography and magnetic resonance imaging revealed gross total removal of the epidural hematoma and complete decompression of the spinal cord all along the affected tract. Early postoperative neurologic examination revealed mild lower extremity weakness that fully recovered within hours. CONCLUSIONS: Although rare, multilevel epidural hematoma following anterior cervical decompression represents a serious complication. The revision of the previous anterior cervical approach may be considered the first treatment option, allowing to control the primary bleeding site. Catheter irrigation of the epidural space with saline solution may be a useful technique for removal of unexposed residual blood collection, avoiding the need for posterior laminectomy or other unnecessary bone demolition.

Entrapment of the temporal horn: case series and systematic review of literature.

INTRODUCTION: Entrapment of the temporal horn (ETH) is a form of focal, obstructive hydrocephalus. Etiology and clinical presentation are diversified. Though known since 1947, standard treatment has not yet been defined. The objective of our study was to perform a systematic review on ETH. EVIDENCE ACQUISITION: Data from patients treated at our Institution from 2008 to 2019 were retrospectively collected and analyzed. A systematic PRISMA review of literature was also performed using PubMed and Google Scholar. The following search terms were used: "temporal horn entrapment" [All Fields] OR "trapped temporal horn" [All Fields]. EVIDENCE SYNTHESIS: One hundred and twenty-one cases (mean age 41 years; M/F ratio: 1/1) were analyzed. In 65 (vs. 56) cases (53.7% vs. 46.3%), ETH was not surgery related. Headache was the most common symptom (42%). "Major" treatments were ventriculoperitoneal/ventriculoatrial shunt (42 cases, 34.7%), and endoscopic ventriculocisternostomy (12 cases, 9.9%). In the first group, no perioperative complications were found, 39 patients (92.9%) had a favorable outcome, three patients (7.1%) died for the underlying disease, four cases (9.5%) went through revision; also considering the cases in which another procedure was performed as definitive treatment, there were six shunt failures (13.6%). In the second group, one case (8.3%) developed a deep intracerebral hemorrhage, 11 cases (91.6%) had a favorable long-term outcome, one case (8.3%) had a favorable short-term outcome; also considering the cases in which another procedure was performed as definitive treatment, there were six endoscopic ventriculocisternostomy failures (37.5%). CONCLUSIONS: Described as uncommon, ETH is probably underestimated. Early diagnosis and appropriate treatment are critical. VP shunt is still the most commonly performed treatment. Further randomized clinical trials are, however, needed to establish the gold standard.

Intracranial capillary hemangiomas: literature review in pediatric and adult population.

Capillary hemangiomas (CHs) of the central nervous system represent a rare diagnosed pathology. CHs are benign vascular tumors whose most common manifestations are dermal and mucous and mainly occur during childhood or adolescence, while the involvement of the central nervous system can occur in a wider age range. We conducted a PubMed research on literature published until March 2020. We only enrolled cases with histological documented presence of intracranial CH. For every case collected, we analyzed age, sex, localization, neuroimaging studies performed, the presence of extracranial CHs, symptoms, neurological deficits, extent of surgical resection (biopsy, partial or gross total), adjunct treatment received (radiotherapy, chemotherapy, Trans-Arterial Embolization TAE), and outcome. Up to March 2020, the literature review identified 52 cases to which we added the case of our personal experience. The mean age was 26 with slightly female prevalence (28 F, 25 M). The most common presenting symptom was headache (21 cases, 40%). The surgical treatment consisted of biopsy in 7 cases (13%), partial resection in 10 cases (19%), gross total resection in 31 cases (58.5%), biopsy followed by total resection in 2 cases (3%), and partial resection followed by total resection in 1 case (1.5%), and the diagnosis was obtained from an autopsy sample in 1 case (1.5%). For symptomatic lesions, surgery is a valid option to obtain histological characterization, neurological improvement, and where possible a total resection. Stereotactic radiotherapy can be used if the lesion is not surgically approachable or as an adjuvant treatment in case of partial resection, having shown good results in terms of long-term disease control.

Rapid spontaneous resolution of lumbar ganglion cysts: A case report.

BACKGROUND: To discuss the rare event of spontaneous resolution of a lumbar ganglion cyst, a personal case report and 25 cases culled from the literature were described in detail. We focused on demographic, classification, clinical and radiological findings, treatment, outcome and radiological resolution. CASE SUMMARY: A 51-year-old man presented to our observation with complaints of low back and right leg pain. Lumbar magnetic resonance imaging (MRI). showed a L4-L5 ganglion cyst. The patient was referred to medical therapy and bracing. After 4 wk, he showed a complete resolution of pain. The complete spontaneous resolution of the cyst was demonstrated by the followed-up MRI. CONCLUSION: Spontaneous resolution of lumbar ganglion is very rare and only 26 cases, including ours, were reported in literature. Different degrees of biomechanical impairment seem to play a fundamental role in the pathogenesis. Related symptoms are essentially represented by low back and/or radicular pain, without significant neurological disorders. Anti-inflammatory drugs, light unloading exercises and brace could be recommended to administrated pain and decrease facet loads. Mean time for clinical improvement was 7 mo, while MRI disappearance occurred in an average time of 11 mo. Therefore, surgery should be applied when conservative treatment, prolonged at least 6 mo, fails.

Arachnoid cyst in young soccer players complicated by chronic subdural hematoma: personal experience and review of the literature.

Arachnoid cysts (ACs) are congenital intracranial benign cavities originating from the meninges during embryological development. Several studies have shown the existence of a relationship between AC and a higher risk to develop ipsilateral chronic subdural hematoma (CSH) especially in a young population. In the presence of an AC, the practice of sport activities may expose young patients to minor head trauma and to an increased risk of developing CSH. We describe three cases of young soccer players with AC associated with CSH. Then, we performed a literature review of all the reported cases in the literature of patients younger than 18 years with AC-associated CSH related to sport practice. A total of 33 cases, including the three cases reported by us, are analyzed. Soccer is the most represented sport activity in this association (39% of cases). The treatment of choice is surgical in all patients, with burr hole or craniotomy in similar proportions. In one-third of patients, the AC has been fenestrated. Outcome is good in all the reported cases. We reviewed the main pathogenic theories, the main surgical strategies described in literature, as well as recurrence rate of CSH, the association of AC and cranial deformities, and the clinical outcome. AC might be associated with skull deformities, but their real incidence remains unclear. The clinical detection of such anomalies should suggest performing further radiological investigations. If the presence of AC is confirmed, the practice of sport activities should not be avoided, as the real incidence of AC-associated CSH is not clear yet and the reported outcomes in literature are good. Surgical treatment of AC-associated CSH should be hematoma removal through burr hole, reserving AC fenestration only for cases with intracystic bleeding or recurrences. The surgeon should adequately advise and inform the young patients and their families that they could have an increased risk of developing CSH given by the presence of the AC, and that they should be referred to a neurosurgical center if they become symptomatic.

A Case of Spinal Cord Compression Due to Paraspinal Musculature After Cervical Laminectomy.

BACKGROUND: Only a few cases of spinal cord compression after cervical laminectomy have been reported. CASE DESCRIPTION: We report a case of tetraparesis after executing a C3-C6 anterior and posterior decompression and fusion. Cervical magnetic resonance imaging demonstrated a spinal cord compression due to the impingement of the paraspinal muscles through the laminectomy. The patient experienced a spontaneous neurological recovery and the follow-up cervical magnetic resonance imaging showed resolution of the spinal cord compression. CONCLUSIONS: This rare complication should be considered among the others after executing a cervical laminectomy.

Thoraco-lumbar fractures with blunt traumatic aortic injury in adult patients: correlations and management.

PURPOSE: Traumatic thoraco-lumbar spine fracture spine with a concomitant blunt aortic injury is uncommon but potentially a fatal association. Our aim was to clarify: morphology of spinal fractures related to vascular damages and vice versa, diagnostic procedures and decision-making process for the best treatment options for spine and vessels. METHODS: We enrolled 42 cases culled from the literature and five personal ones, reviewing in detail by AO Spine Classification, Society of Vascular Surgery classification and Abbreviated Injury Scale for neurological evaluation. RESULTS: Most fractures were at T11-L2 (29 cases; 62%) and type C (17; 70%). 17 (38%) were neurological. Most common vascular damage was the rupture (20; 43%), followed by intimal tear (13; 28%) and pseudoaneurysm (9; 19%). Vascular injury often required open or endovascular repair before spinal fixation. Distraction developed aortic intimal damage until rupture, while flexion-distraction lumbar artery pseudoaneurysm and rotation-torsion full laceration of collateral branches. CT and angio-CT were investigations of choice, followed by angiography. Neurological condition remained unchanged in 28 cases (90%). Overall mortality was 30%, but it was higher in AIS A. CONCLUSION: Relationship between thoraco-lumbar fracture and vascular lesion is rare, but potentially fatal. Comprehension of spinal biomechanics and vascular damages could be crucial to avoid poor results or decrease mortality. Frequently, traction of the aorta and its vessels is realized by C-dislocated fractures. CT and angio-CT are recommended. Spine stabilization should always follow the vascular repair. Early severe deficits worse the prognosis related to neurological recovery and survival. These slides can be retrieved under Electronic Supplementary Material.
