RESUMO

Though uncommon in developed countries, spinal tuberculosis must still be considered in patients with a suspicious clinical history, to avoid delays in treatment. This case series highlights the special considerations that need to be taken into account while tackling the diagnostic and therapeutic challenges associated with this disease. We present two interesting cases of spinal tuberculosis. The first case was a 26-year-old female who presented with chronic back pain and an initial misdiagnosis of ankylosing spondylitis. The second case was a 26-year-old male with new lower extremity weakness, numbness, and urinary retention. Both cases had clear indications for surgery, however, the first case was treated with medical management upon patient request. The patient was managed non-surgically and improved clinically though she may need surgery in the future. The second case was treated with emergency surgery and the patient regained full neurologic function at follow-up. These cases demonstrate the importance of considering spinal tuberculosis in the differential diagnosis of high-risk patients as well as individualizing treatment strategies for each patient.

RESUMO

There are few reliable morphologic indices to aid in the determination of an intracranial aneurysm's rupture risk. We sought to characterize morphological characteristics of aneurysm sacs and their lobes that are associated with ruptured status at time of initial evaluation with diagnostic angiography. These factors could be associated with an aneurysm's risk of rupturing. We retrospectively reviewed all aneurysms imaged with digital subtraction angiography (DSA) at a single institution over five years. Patients presenting with aneurysmal subarachnoid hemorrhage (aSAH) were assigned to the ruptured group, and those presenting without aSAH were assigned to the unruptured group. Angiograms were evaluated for the presence of various morphological parameters. Binary logistic regression was used to assess their associations between groups. A total of 331 aneurysms among 241 patients were included in the analysis. Posterior circulation, larger size ratio, and the presence of two or more lobes were associated with aneurysm rupture (p < 0.001 for each). Aneurysms containing a lobe with a greater height than width were observed more frequently in the ruptured group (OR 5.26, 95% CI 2.66-10.41). In the receiver operating characteristic (ROC) curves, mean diameter had an AUC of 0.72 and an optimum threshold of 2.85 mm. For size ratio, the AUC was 0.70 and the optimum threshold was 2.02. A larger SR was observed in ruptured aneurysms. The presence of multiple lobes and greater lobe height than width were associated with rupture status as well. These factors merit investigation in a prospective study.

RESUMO

OBJECTIVETraumatic brain injury (TBI) is a major cause of long-term disability and death in young adults. The lack of pharmaceutical therapy for post-acute TBI recovery remains a crucial medical challenge. Stem cell factor (SCF) and granulocyte colony-stimulating factor (G-CSF), which are 2 key hematopoietic growth factors, have shown neuroprotective and neurorestorative effects in experimental stroke. The objective of this study was to determine the therapeutic efficacy of combined treatment (SCF + G-CSF) in subacute TBI.METHODSYoung-adult male C57BL mice were subject to TBI in the cortex of the right hemisphere. After TBI induction, mice were randomly divided into 2 groups: a vehicle control group and an SCF + G-CSF treatment group. Mice without TBI served as sham operative controls. Treatment was initiated 2 weeks after TBI induction. SCF (200 µg/kg) and G-CSF (50 µg/kg) or an equal volume of vehicle solution was subcutaneously injected daily for 7 days. A battery of neurobehavioral tests for evaluation of memory and cognitive function (water maze and novel object recognition tests), anxiety (elevated plus maze test), and motor function (Rota-Rod test) was performed during the period of 2-9 weeks after treatment. Neurodegeneration and dendritic density in both hemispheres were determined through histochemistry and immunohistochemistry at 11 weeks posttreatment.RESULTSWater maze testing showed that TBI-impaired spatial learning and memory was restored by SCF + G-CSF treatment. The findings from the elevated plus maze tests revealed that SCF + G-CSF treatment recovered TBI-caused anxiety and risk-taking behavior. There were no significant differences between the treated and nontreated TBI mice in both the Rota-Rod test and novel object recognition test. In the brain sections, the authors observed that widespread degenerating neurons were significantly increased in both hemispheres in the TBI-vehicle control mice. TBI-induced increases in neurodegeneration were significantly reduced by SCF + G-CSF treatment in the contralateral hemisphere, making it no different from that of the sham controls. Dendritic density in the frontal cortex of the contralateral hemisphere was significantly reduced in the TBI-vehicle control mice, whereas SCF + G-CSF-treated TBI mice showed significant increases of the dendritic density in the same brain region. SCF + G-CSF-treated TBI mice also showed a trend toward increasing dendritic density in the contralateral hippocampus.CONCLUSIONSSCF + G-CSF treatment in the subacute phase of TBI restored TBI-impaired spatial learning and memory, prevented posttraumatic anxiety and risk-taking behavior, inhibited TBI-induced neurodegeneration, and enhanced neural network remodeling. These findings suggest the therapeutic potential of hematopoietic growth factors for brain repair in the subacute phase of TBI.

RESUMO

Traumatic brain injury (TBI) presents in various forms ranging from mild alterations of consciousness to an unrelenting comatose state and death. In the most severe form of TBI, the entirety of the brain is affected by a diffuse type of injury and swelling. Treatment modalities vary extensively based on the severity of the injury and range from daily cognitive therapy sessions to radical surgery such as bilateral decompressive craniectomies. Guidelines have been set forth regarding the optimal management of TBI, but they must be taken in context of the situation and cannot be used in every individual circumstance. In this review article, we have summarized the current status of treatment for TBI in both clinical practice and basic research. We have put forth a brief overview of the various subtypes of traumatic injuries, optimal medical management, and both the noninvasive and invasive monitoring modalities, in addition to the surgical interventions necessary in particular instances. We have overviewed the main achievements in searching for therapeutic strategies of TBI in basic science. We have also discussed the future direction for developing TBI treatment from an experimental perspective.

RESUMO

INTRODUCTION: Pure choriocarcinoma of the testes is a rare, aggressive germ cell tumor that can metastasize to the brain. Although its prognosis has improved with the development of cisplatin-based chemotherapy regimens, cerebral metastases are prone to hemorrhage and associated with high morbidity. Here, we present 2 cases of testicular choriocarcinoma with cerebral metastasis and discuss potential pitfalls in their diagnosis and management. We also review cases in the literature that feature these rare lesions. METHODS: Medline was searched for all publications including the terms "testicular choriocarcinoma" and "cerebral metastasis" or "brain metastasis." Articles that included patients with tumors classified as a mix of choriocarcinoma and other germ cell tumor subtypes were excluded. RESULTS: A total of 15 cases from the literature and our own 2 cases were included in the analysis. The mean age at presentation was 25.5 years. Neurologic symptoms accounted for the initial presentation of 9 patients (60%). Outcomes were predominantly poor, with 10 patients (67%) expiring shortly after their initial diagnosis. Three of these deaths were related to mass effect from metastasis-related hemorrhages. Two patients underwent emergent decompressive craniectomies, and both died from cerebral herniation. CONCLUSION: The potentially catastrophic nature of choriocarcinoma-related cerebral hemorrhages underscores the need for prompt, accurate diagnosis and aggressive surgical management of these lesions. Their highly vascular nature and lack of findings on cerebral angiography may cause them to be confused with occult vascular malformations.

RESUMO

Late complications of spinal cord injury can include Charcot arthropathy, in which spinal instability occurs as a result of repetitive trauma in the insensate spine. In rare cases, this can present as autonomic dysreflexia. We present the case of a 60-year-old man with longstanding C6 quadriplegia who presented with six months of hypertension, diaphoresis and dizziness. After an extensive workup, the patient's symptoms were attributed to autonomic dysreflexia in the setting of spinal instability from Charcot spinal arthropathy. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed instability with degenerative changes at L1-L2. We present our case with a literature review to discuss management of this uncommon situation. The patient underwent posterior fusion and instrumentation from T8-L5 with four rods, alternating screws and crosslinks with a good reduction and solid stabilization of the spine. Postoperatively, the patient experienced immediate relief of all symptoms. Our case demonstrates effective surgical treatment for Charcot spinal arthropathy causing autonomic dysreflexia. Stabilization with instrumentation and fusion of underlying Charcot spinal arthropathy removed the trigger of the autonomic dysreflexia and alleviated our patient's symptoms.

RESUMO

INTRODUCTION: Penetrating traumatic brain injuries (TBIs), with the exception of gunshot wounds, are relatively rare occurrences and affect all ages. Clinical presentation varies depending on the mechanism of the injury. Prompt surgical treatment is often indicated and is influenced by patient clinical examination, anatomic trajectory, and the penetrating object's size, shape, and velocity. METHODS: We present 3 cases of penetrating TBI. Their similarities and differences affecting operative and medical management are compared. We relate our experience with management of penetrating intracranial foreign bodies in general and discuss the relevant literature. RESULTS: Our first case was a 12-year-old male who presented with a self-inflicted transfacial transcranial injury by a crossbow. The arrow passed through the left sphenoid and cavernous sinus and exited through the parietal calvarium. Our second case was a 37-year-old man with a transoral intracranial stab wound by a knife. In our third case, we present a 46-year-old male who accidentally fired a nail gun into his right ear. The nail traversed the posterior wall of the external auditory canal into the posterior fossa, ending in the cerebellar vermis. Each case was treated with craniotomy and foreign body removal. All resulted in good outcomes after surgical treatment. CONCLUSION: Surgery in penetrating TBI is the treatment of choice. Our cases demonstrate how certain principles applied to individual patient scenarios may optimize clinical results. Severity of the injury and operative approach are among the most important considerations to achieve the best patient outcomes.

RESUMO

INTRODUCTION: Thyroid carcinoma initially presents with clinical symptoms due to metastatic lesions in less than 5% of cases. Spinal cord compression from an epidural metastatic lesion as a first symptom is extremely rare. One would expect such a presentation to occur much later in the course of the disease. METHODS: We are presenting a case report of a follicular thyroid carcinoma that presented with spinal cord compression from a thoracic epidural metastatic lesion in a previously healthy 55-year-old male. A single metastasis of follicular thyroid carcinoma presenting with posterior spinal cord compression is rare. In this particular case, our management included a mid-thoracic laminectomy, followed by resection of the epidural lesion. Once the surgical pathology confirmed the diagnosis of a follicular thyroid carcinoma, the general surgery team performed a near total thyroidectomy, after which he received radioactive iodine therapy. The patient is symptom-free at his three-year follow-up. CONCLUSION: Initial presentation of follicular thyroid carcinoma with symptomatic thoracic myelopathy from an epidural metastasis is very uncommon. An early diagnosis and prompt surgical intervention provided an excellent outcome.

RESUMO

Less invasive surgical approaches for intracranial aneurysm clipping may reduce length of hospital stay, surgical morbidity, treatment cost, and improve patient outcomes. We present our experience with a minimally invasive pterional approach for anterior circulation aneurysms performed in a major tertiary cerebrovascular center and compare the results with an aged matched dataset from the Nationwide Inpatient Sample (NIS). From August 2008 to December 2012, 22 elective aneurysm clippings on patients ≤55 years of age were performed by the same dual fellowship-trained cerebrovascular/endovascular neurosurgeon. One patient (4.5%) experienced transient post-operative complications. 18 of 22 patients returned for follow-up imaging and there were no recurrences through an average duration of 22 months. A search in the NIS database from 2008 to 2010, also for patients aged ≤55 years of age, yielded 1,341 hospitalizations for surgical clip ligation of unruptured cerebral aneurysms. Inpatient length of stay and hospital charges at our institution using the minimally invasive thumb-sized pterional technique were nearly half that of NIS (length of stay: 3.2 vs 5.7 days; hospital charges: $52,779 vs. $101,882). The minimally invasive thumb-sized pterional craniotomy allows good exposure of unruptured small and medium-sized supraclinoid anterior circulation aneurysms. Cerebrospinal fluid drainage from key subarachnoid cisterns and constant bimanual microsurgical techniques avoid the need for retractors which can cause contusions, localized venous infarctions, and post-operative cerebral edema at the retractor sites. Utilizing this set of techniques has afforded our patients with a shorter hospital stay at a lower cost compared to the national average.

RESUMO

OBJECTIVE: The purpose of this study was to describe the effectiveness of local vascularized flaps for the repair of various skull base defects. METHODS: We analyzed a cohort of 138 patients undergoing skull base surgery in a retrospective review of all head and neck surgical oncology cases done at a major tertiary care center between 2005 and 2008. RESULTS: Eighteen patients met our inclusion criteria, requiring local vascularized flap or free graft reconstruction. The mean age of our patients was 39.7 years, with an equal distribution of men and women. The mean follow-up was 16.4 months. Neoplastic causes accounted for the majority of skull base lesions (11/18 cases), followed by traumatic lesions (5/18 cases). Other causes of lesions in our study included encephalocele (1 case), and infection (1 case). The most common location for skull base defects in our study was the anterior skull base (14/18 cases). Other locations included the infratemporal fossa (1 case). The mean size of defect repaired was 4.46 cm, and the mean area was 12.85 cm(2). Repair with local vascularized tissue flaps resulted in a success rate of 87.5%. Moreover, our meningitis and cerebrospinal fluid leak rate was only 11.1% after repair. CONCLUSION: Local vascularized flap utilization in open reconstruction of the skull base has an excellent success rate, with no second donor site morbidity. The success is comparable to free tissue transplant reconstruction and should be in the armamentarium of every neurosurgeon and skull base surgeon. Appropriate incision planning and preoperative evaluation and selection is essential for the success of this type of reconstructive technique.

RESUMO

The role of preoperative embolization in meningioma management remains controversial, even though 4 decades have passed since it was first described. It has been shown to offer benefits such as decreased blood loss and "softening of the tumor" during subsequent resection. However, the actual benefits remain unclear, and the potential harm of an additional procedure along with the cost of embolization have limited its use to a small proportion of the meningiomas treated. In this article the authors retrospectively reviewed their experience with preoperative embolization of meningiomas over the previous 6 years (March 2007-March 2013). In addition, they performed a MEDLINE search using a combination of the terms "meningioma," "preoperative," and "embolization" to analyze the indications, embolizing agents, timing, and complications reported during preoperative embolization of meningiomas. In this retrospective review, 18 cases (female/male ratio 12:6) were identified in which endovascular embolization was used prior to resection of an intracranial meningioma. Craniotomy for tumor resection was performed within 4 days after endovascular embolization in all cases, with an average time to surgery of 1.9 days. The average duration of surgery was 4 hours and 18 minutes, and the average blood loss was 574 ml, with a range of 300-1000 ml. Complications following endovascular therapy were identified in 3 (16.7%) of 18 cases, including one each of transient hemiparesis, permanent hemiparesis, and tumor swelling. The literature review returned 15 articles consisting of a study population greater than 25 patients. No randomized controlled study was found. The use of small polyvinyl alcohol particles (45-150 µm) is more effective in preoperative devascularization than larger particles (150-250 µm), but is criticized due to the higher risk of complications such as cranial nerve palsies and postprocedural hemorrhage. Time to surgery after embolization is inconsistently reported across the articles, and conclusions on the appropriate timing of surgery could not be drawn. The overall complication rate reported after treatment with preoperative meningioma embolization ranges from as high as 21% in some of the older literature to approximately 6% in recent literature describing treatment with newer embolization techniques. The evidence in the literature supporting the use of preoperative meningioma embolization is mainly from case series, and represents Level III evidence. Due to the lack of randomized controlled clinical trials, it is difficult to draw any significant conclusions on the overall usefulness of preoperative embolization during the management of meningiomas to consider it a standard practice.

RESUMO

OBJECTIVE: The neuropathologic findings of chronic traumatic encephalopathy (CTE) were first described almost 40 years after the first clinical reports. We reviewed the literature and describe the neuropathological findings seen primarily in professional athletes and more recently, in war veterans. METHODS: We reviewed the literature of CTE concentrating on references that focused on the correlation of clinical findings with the neuropathologic changes. The pathobiology and proposed mechanisms of injury are described. Diagnostic modalities and various diagnostic criteria of CTE are reviewed. RESULTS: We are beginning to understand the neuropathologic basis of CTE, which appears to be a consequence of repetitive mild brain injuries. There appear to be reproducible criteria for the post-mortem diagnosis of CTE and the neuropathologic findings are becoming more widely accepted. More research is required to elucidate the risk factors that predispose athletes and war veterans to CTE. There is also a need for more diagnostic markers and a method to assess CTE in patients prior to death. The neuropathologic findings of a progressive tauopathy including the presence of numerous neurofibrillary tangles (NFTs), rare neuritic plaques, and widespread expression of TDP-43 (transactive response [TAR] DNA binding protein 43) also require further study. DISCUSSION: The potential prevalence of CTE, as well as the vulnerable populations involved, makes research into this topic crucial. Currently, a comprehensive neurological exam, neuropsychiatric assessment, and standard radiographic techniques such as conventional MRI are the mainstay of diagnosis. There is a pressing need for the prevention of CTE and the development of non-invasive diagnostic tests in order to develop therapies that may be of clinical use to athletes and blast injury veterans during their lifetimes.

RESUMO

Intramedullary primary central nervous system lymphoma (PCNSL) is a rare central nervous system (CNS) malignancy affecting mostly the brain, but it may also involve the leptomeninges, eyes, and spinal cord. A 71-year-old woman presented with back pain and progressive unilateral lower extremity weakness owing to an intramedullary primary histiocytic sarcoma of the spine, a rare PCNSL subtype. To the authors' knowledge, this is the first case of an intramedullary PCNSL caused by histiocytic sarcoma.

RESUMO

Long thoracic nerve palsy has been reported to have traumatic, iatrogenic, and idiopathic causes. The authors describe the case of a 62-year-old man who presented with progressively worsening right shoulder pain, winging of the scapula, and Horner syndrome. A chest CT scan revealed an apical pulmonary mass. To the authors' knowledge, this is the first report of a long thoracic nerve palsy caused by an apical pulmonary tumor.
