Sample records for spinal meningeal melanocytoma

  1. Spinal meningeal melanocytoma and hydrocephalus and intracranial superficial siderosis

    Das, A.; Ratnagopal, P.; Puvanendran, K.; Teo, J.G.C.

    2001-01-01

    Meningeal melanocytomas are uncommon tumours of the central nervous system; fewer than 50 cases have been reported in the English literature. We review the unique clinical presentation, radiological appearance and histological features of a rare case of meningeal melanocytoma. The patient was a 50-year-old man with a history of hypertension who presented with complaints of severe headache, nausea, vomiting and blurry vision for 2 days. Clinical examination revealed no hyperpigmentation marks and he had no history of regressed skin melanocytic lesions. Apart from mild terminal neck stiffness, his general medical examination was unremarkable. On funduscopic examination he had marked bilateral papilloedema and the blind spots were enlarged bilaterally. His neurological examination was otherwise unremarkable. A magnetic resonance imaging scan (MRI) of the brain showed hydrocephalus. On the precontrast T 2 -weighted images, there was hyperintensity of the meninges with little change after administration of gadolinium, which was suggestive of blood. On the T 2 -weighted sequences, there was evidence of hypo-i intensity on the surface of the pons and medulla, which was indicative of superficial siderosis

  2. Intramedullary spinal melanocytoma

    Full Text Available Meningeal melanocytoma is a benign lesion arising from leptomeningeal melanocytes that at times can mimic its malignant counterpart, melanoma. Lesions of the spine usually occur in extramedullary locations and present with spinal cord compression symptoms. Because most reported spinal cases occur in the thoracic region, these symptoms usually include lower extremity weakness or numbness. The authors present a case of primary intrame­dullary spinal meningeal melanocytoma presenting with bilateral lower extremity symptoms in which the patient had no known supratentorial primary lesions. Gross total surgical resection allowed for full recovery, but early recurrence of tumor was detected on close follow-up monitoring, allowing for elective local radiation without loss of neurological function. Case reports of such tumors discuss different treatment strategies, but just as important is the close follow-up monitoring in these patients even after gross total surgical resection, since these tumors can recur.

  3. Spinal meningeal melanocytoma with benign histology showing leptomeningeal spread: Case report

    Kim, Ok Hwa; Kim, Seon Jeong; Choo, Hye Jung; Lee, Sun Joo; Kim, Ji Yeon; Kim, Hoon; Lee, In Sook

    2013-01-01

    Meningeal melanocytoma is a rare benign tumor with relatively good prognosis. However, local aggressive behavior of meningeal melanocytoma has been reported, especially in cases of incomplete surgical resection. Malignant transformation was raised as possible cause by prior reports to explain this phenomenon. We present an unusual case of meningeal melanocytoma associated with histologically benign leptomeningeal spread and its subsequent aggressive clinical course, and describe its radiological findings.

  5. Spinal meningeal melanocytoma in a 5-year-old child: a case report and review of literature.

    Salah El-Din, Ahmed M; Aboul-Ela, Hashem M; Alsawy, Mohamed F; Koheil, Ahmed; Ashry, Ahmed H

    2018-01-01

    Meningeal melanocytoma is considered a rare lesion arising from leptomeningeal melanocytes. Nearly two thirds of meningeal melanocytomas were reported in the intracranial compartment and the remaining one third in the spine. Spinal melanocytomas can be extradural or intradural, with extradural variant being more common, and the majority of cases have been single reports. A 5-year-old male presented with a 4-month history of non-radiating low back pain persistent at rest, with otherwise non-remarkable medical history. The patient was neurologically intact with no deficits. Preoperatively, routine laboratory investigations were non-remarkable. MRI imaging was done and showed a lesion at the level of T11 to L4, hyperintense on T1 and hypointense on T2 with homogenous contrast enhancement. Intraoperatively, the lesion was hemorrhagic, brownish, and rubbery in consistency attached to the ventral dura. Microscopic picture revealed dense cytoplasmic brown melanin pigments, with no significant mitoses or nuclear atypia. What is unique about our case is the age of the patient (5 years). To the best of our knowledge, after reviewing the literature, this is the youngest case to be reported. SMM is an extremely rare tumor with a benign course. Complete surgical excision should be attempted. Age of presentation may be as young as in our case and the diagnosis of such a tumor should never be excluded in this early age group with persistent low back ache.

  6. The value of radiotherapy for the treatment of meningeal melanocytoma

    Rades, D.; Karstens, J.H.; Tatagiba, M.; Brandis, A.; Dubben, H.H.

    2002-01-01

    Background: Meningeal melanocytoma is described as rare benign lesion with a high risk of recurrence. There are no well-substantiated treatment recommendations in the literature. Only case reports have been published by now. Patients and Methods: In 1997 a patient was irradiated for a recurrent spinal meningeal melanocytoma and 2 years later for brain metastases indicating malignant transformation. This case gave rise to a literature review for therapeutic options. All sufficiently documented cases published since 1972, when the term meningeal melanocytoma was established, were evaluated. Based on published and on original data recurrence and overall survival rates up to 5 years were calculated for three different therapeutic approaches, namely complete tumor resection, incomplete resection with subsequent radiotherapy, and incomplete resection alone. Statistical evaluation was performed using the χ 2 test and Kaplan-Meier-analysis. Results: 53 patients (including our patient) met selection criteria. Complete tumor resection was superior to incomplete resection alone with lower recurrence (4-38% versus 50-92%) and better overall survival rates (86-95% versus 30-58%). After incomplete resection radiotherapy seemed to improve prognosis (recurrence 15-45%; overall survival 91-92%). Between complete resection and incomplete resection plus radiotherapy no significant differences were observed. Conclusions: For meningeal melanocytoma complete resection must be regarded as the best of the modalities compared. After incomplete resection radiotherapy should be considered, although a specific radiotherapeutic regimen cannot be recommended at present. However, for multiple cranial or spinal lesions total cranial irradiation or craniospinal irradiation is indicated. (orig.) [de

  8. Anatomy of the Spinal Meninges.

    Sakka, Laurent; Gabrillargues, Jean; Coll, Guillaume

    2016-06-01

    The spinal meninges have received less attention than the cranial meninges in the literature, although several points remain debatable and poorly understood, like their phylogenesis, their development, and their interactions with the spinal cord. Their constancy among the chordates shows their crucial importance in central nervous system homeostasis and suggests a role far beyond mechanical protection of the neuraxis. This work provides an extensive study of the spinal meninges, from an overview of their phylogenesis and embryology to a descriptive and topographic anatomy with clinical implications. It examines their involvement in spinal cord development, functioning, and repair. This work is a review of the literature using PubMed as a search engine on Medline. The stages followed by the meninges along the phylogenesis could not be easily compared with their development in vertebrates for methodological aspects and convergence processes throughout evolution. The distinction between arachnoid and pia mater appeared controversial. Several points of descriptive anatomy remain debatable: the functional organization of the arterial network, and the venous and lymphatic drainages, considered differently by classical anatomic and neuroradiological approaches. Spinal meninges are involved in neurodevelopment and neurorepair producing neural stem cells and morphogens, in cerebrospinal fluid dynamics and neuraxis functioning by the synthesis of active molecules, and the elimination of waste products of central nervous system metabolism. The spinal meninges should be considered as dynamic functional formations evolving over a lifetime, with ultrastructural features and functional interactions with the neuraxis remaining not fully understood.

  9. Post spinal meningitis and asepsis.

    Videira, Rogerio L R; Ruiz-Neto, P P; Brandao Neto, M

    2002-07-01

    Post spinal meningitis (PSM) is a complication still currently being reported. After two PSM cases in our hospital an epidemiological study was initiated, which included a survey of techniques for asepsis that are applied in our department. Cases defined as PSM comprised meningitis within a week after spinal anesthesia. Anesthesia records, anesthesia complication files and the records of the Hospital Commission for Infection Control from 1997 to 2000 were reviewed. Asepsis techniques applied were surveyed by a questionnaire answered by all our department's anesthesiologists. The equipment and procedures for spinal anesthesia were listed. Current anesthesia textbooks were reviewed for recommendations regarding asepsis techniques in conjunction with spinal anesthesia. Three cases of PSM were identified following 38,128 spinal anesthesias whereas none was observed in 12,822 patients subjected to other types of regional or general anesthesia (P>0.05). Culture of cerebrospinal fluid yielded Streptococcus in two patients and was negative in the other patient. The asepsis technique applied by the anesthesiologists varied considerably. The literature review showed that aspects on asepsis for spinal anesthesia are poorly covered. The incidence of meningitis was similar in patients subjected to spinal anesthesia and in those subjected to other anesthetic techniques. Asepsis techniques were found to differ considerably among our staff members, reflecting the lack of well-defined published standards for this procedure. We recommend that asepsis for spinal anesthesia should not be less rigorous than for surgical asepsis.

  10. Spinal cord involvement in tuberculous meningitis.

    Garg, R K; Malhotra, H S; Gupta, R

    2015-09-01

    To summarize the incidence and spectrum of spinal cord-related complications in patients of tuberculous meningitis. Reports from multiple countries were included. An extensive review of the literature, published in English, was carried out using Scopus, PubMed and Google Scholar databases. Tuberculous meningitis frequently affects the spinal cord and nerve roots. Initial evidence of spinal cord involvement came from post-mortem examination. Subsequent advancement in neuroimaging like conventional lumbar myelography, computed tomographic myelography and gadolinium-enhanced magnetic resonance-myelography have contributed immensely. Spinal involvement manifests in several forms, like tuberculous radiculomyelitis, spinal tuberculoma, myelitis, syringomyelia, vertebral tuberculosis and very rarely spinal tuberculous abscess. Frequently, tuberculous spinal arachnoiditis develops paradoxically. Infrequently, spinal cord involvement may even be asymptomatic. Spinal cord and spinal nerve involvement is demonstrated by diffuse enhancement of cord parenchyma, nerve roots and meninges on contrast-enhanced magnetic resonance imaging. High cerebrospinal fluid protein content is often a risk factor for arachnoiditis. The most important differential diagnosis of tuberculous arachnoiditis is meningeal carcinomatosis. Anti-tuberculosis therapy is the main stay of treatment for tuberculous meningitis. Higher doses of corticosteroids have been found effective. Surgery should be considered only when pathological confirmation is needed or there is significant spinal cord compression. The outcome in these patients has been unpredictable. Some reports observed excellent recovery and some reported unfavorable outcomes after surgical decompression and debridement. Tuberculous meningitis is frequently associated with disabling spinal cord and radicular complications. Available treatment options are far from satisfactory.

    2010-01-01

    Objective: To analyze the characteristics of spinal meningeal cyst in low-field MRI and to discuss its classification, subtype, clinical presentation, and differential diagnosis. Methods: Forty-two patients (20 male, 22 female) were examined with sagittal T 1 -and T 2 -, axial T 2 -weighted MR imaging. Twelve patients were also examined with contrast-enhanced MRI. Results: The cysts were classified using Nakors' classification as type Ia extradural meningeal cysts (4 patients), type Ib sacral meningeal cysts (32), type II extradural meningeal cysts with spinal nerve root fibers (4), and type III spinal intradural meningeal cysts (2). All 42 spinal meningeal cysts had well-defined boundaries with low T 1 and high T 2 signal intensities similar to cerebral spinal fluid. In type Ia, the lesions were often on the dorsum of mid-lower thoracic spinal cord compressing the spinal cord and displacing the extradural fat. In type Ib, the lesions were in the sacral canal with fat plane between the cyst and dural sac. In type II, the lesions contained nerve roots and were lateral to the dural sac. In type III, the lesions were often on the dorsum of spinal cord compressing and displacing the spinal cord anteriorly. Conclusion: Low-field MRI can clearly display the spinal meningeal cyst. Types Ia and Ib spinal meningeal cysts had typical features and can be easily diagnosed. Types II and III should be differentiated from cystic schwannomas and enterogenous cysts, respectively.

  12. Extramedullary spinal teratoma presenting with recurrent aseptic meningitis.

    Mpayo, Lucy L; Liu, Xiao-Hong; Xu, Man; Wang, Kai; Wang, Jiao; Yang, Li

    2014-06-01

    Spinal teratomas are extremely rare; they constitute meningitis. A 7-year-old boy presented with paroxysmal abdominal pain and a history of recurrent aseptic meningitis. Kernig and Brudzinski signs were present. Lumber puncture revealed pleocytosis with no evidence of bacteria growth. Imaging of the spine revealed a cystic lesion in spinal cord at thoracic level 9-11. Endoscopic excision of the cyst was successfully performed. Surgical and histopathological findings confirmed extramedullary matured teratoma. As the symptomatic attacks of spontaneous rupture of spinal teratoma resemble presentations of Mollaret meningitis, spinal teratoma should be considered in the differential diagnosis of Mollaret meningitis. We describe a rare example of spinal teratoma causing recurrent meningitis. Spine imaging should be considered in individuals with recurrent aseptic meningitis as this promotes earlier diagnosis, more appropriate treatment, and improved neurological outcome.

    2014-07-01

    Meningitis following lumbar puncture and spinal anaesthesia is a rare but serious complication. A 19-year-old woman was administered spinal anaesthesia at another centre prior to a Caesarean section. The following day she experienced headaches. On the fourth day, she started vomiting and having convulsions, and became agitated. Meningitis was diagnosed based on a clinical examination and analysis of a lumbar puncture sample. After 21 days of treatment, she was discharged. Meningitis should be considered in the differential diagnosis of a patient presenting with headaches following spinal anaesthesia. The causes of meningitis following spinal anaesthesia are debated, and it is difficult to distinguish between aseptic and bacterial meningitis. It should be compulsory to wear a face mask while performing a dural puncture. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  14. Iris melanocytoma.

    Radovanović, Anica Bobić; Krnjaja, Bojana Dacić; Jaksić, Vesna

    2016-01-01

    Iris melanocytoma (IM) is a rare benign tumor, but unavoidable in differential diagnosis of pigmented iris lesions. According to the best knowledge of the authors it is for the first time in Serbia that a well-documented case of IM is presented and that the problem of this tumor is discussed. In the left eye of a 47-year-old white female at the iris in a six o'clock position, a highly pigmented, dome shaped lesion with a crater-like cavity in the center and with feathery margins was noticed. There were no signs of infiltration of surrounding tissue or intrinsic vessels and the lens was clear. Visual acuity and intraocular pressure were normal. An ultrasound biomicroscopy (UBM) revealed a well-defined lesion with high internal reflectivity, with a base diameter of 1.25 mm and a thickness of 0.80 mm in the periphery, and 0.53 mm in the central part.The diagnosis of IM of the left eye was established and regular checkups were performed for ten years. No changes in clinical or UBM presentation were established. Awareness of clinical presentation of IM is most important for correct diagnosis. Ultrasound biomicroscopy is a useful diagnostic procedure in the following up of IM.

    2018-02-01

    Current recommendations support early surgical decompression and blood pressure augmentation after traumatic spinal cord injury (SCI). Elevated intraspinal pressure (ISP), however, has probably been underestimated in the pathophysiology of SCI. Recent studies provide some evidence that ISP measurements and durotomy may be beneficial for individuals suffering from SCI. Compression of the spinal cord against the meninges in SCI patients causes a "compartment-like" syndrome. In such cases, intentional durotomy with augmentative duroplasty to reduce ISP and improve spinal cord perfusion pressure (SCPP) may be indicated. Prior to performing these procedures routinely, profound knowledge of the spinal meninges is essential. Here, we provide an in-depth review of relevant literature along with neuroanatomical illustrations and imaging correlates.

    Highlights: •This was a prospective study to evaluate role of spinal ultrasound (US) in 60 infants (<6 months of age) with clinically suspected meningitis. •On ultrasound examination, we evaluated echogenicity and /or trabeculations in the posterior subarachnoid space and spinal cord pulsations. •Results of spinal US were evaluated in correlation with cerebrospinal fluid analysis. •Results of our study show presence of echogenicity/trabeculations in posterior subarachnoid space or abnormal pulsations of spinal cord and nerve roots are significantly associated with meningitis with a high specificity and positive predictive value in its diagnosis. •Spinal ultrasound can be used as a radiation free imaging modality to detect meningitis. -- Abstract: Background: Spinal ultrasound (US) can detect changes in CSF echogenicity and decreased cord pulsations which reflect the inflammatory changes in meningitis. Till date, there is no published data about the prospective accuracy of spinal US in meningitis. Objective: To assess accuracy of spinal US in diagnosis of meningitis in infants younger than 6 months. Methods: This was an institute ethics committee approved prospective study carried out in infants less than 6 months of age with clinical suspicion of meningitis who presented to pediatric emergency unit. 60 infants each in study and control group were enrolled. US of thoraco-lumbar spine were performed prior to lumbar puncture in all cases. We looked for the presence of echogenicity or trabeculations in posterior subarachnoid space and for presence or absence of spinal cord and nerve root pulsations on real time ultrasound. The results of spinal US were evaluated in correlation with cerebrospinal fluid analysis. Follow up ultrasounds were done in infants who showed abnormal findings after the initiation of treatment and findings compared with initial results. Results: The study group comprised of 40 boys and 20 girls with mean age of 47.85 days. The control

    Subarachnoid hemorrhage (SAH) of spinal origin is uncommon in clinical practice, and spinal schwannomas associated with SAH are even more rarely reported. We report an unusual case of spinal SAH mimicking meningitis with normal brain computed tomography (CT)/magnetic resonance imaging (MRI) and negative CT angiography. Cerebrospinal fluid examination results were consistent with the manifestation of SAH. Spinal MRI performed subsequently showed an intradural extramedullary mass. The patient received surgery and was finally diagnosed with spinal cord schwannoma. A retrospective chart review of the patient was performed. We describe a case of SAH due to spinal cord schwannoma. Our case highlights the importance of careful history taking and complete evaluation. We emphasize that spinal causes should always be ruled out in patients with angionegative SAH and that schwannoma should be considered in the differential diagnosis of SAH etiologies even though rare.

    Adult spinal cord has little regenerative potential, thus limiting patient recovery following injury. In this study, we describe a new population of cells resident in the adult rat spinal cord meninges that express the neural stem/precursor markers nestin and doublecortin. Furthermore, from dissociated meningeal tissue a neural stem cell population was cultured in vitro and subsequently shown to differentiate into functional neurons or mature oligodendrocytes. Proliferation rate and number of nestin- and doublecortin-positive cells increased in vivo in meninges following spinal cord injury. By using a lentivirus-labeling approach, we show that meningeal cells, including nestin- and doublecortin-positive cells, migrate in the spinal cord parenchyma and contribute to the glial scar formation. Our data emphasize the multiple roles of meninges in the reaction of the parenchyma to trauma and indicate for the first time that spinal cord meninges are potential niches harboring stem/precursor cells that can be activated by injury. Meninges may be considered as a new source of adult stem/precursor cells to be further tested for use in regenerative medicine applied to neurological disorders, including repair from spinal cord injury.

  8. Spinal meningeal uptake of technetium-99m methylene diphosphonate in meningeal seeding by malignant lymphoma

    Siegal, T.; Or, R.; Matzner, Y.; Samuels, L.D.

    1980-01-01

    Definite diagnosis of meningeal seeding by systemic cancer relies on the presence of malignant cells in the cerebrospinal fluid (CSF). In the absence of such cells in the CSF, only two other tests strongly suggest the diagnosis - a CT scan and a myelogram. This paper reports a case in which the diagnosis was strongly suggested by an unusual uptake of Tc-99m methylene diphosphonate by the leptomeninges during a skeletal scan and later established by the presence of malignant cells in the CSF. The radionuclide scan may be an additional diagnostic test in some cases with meningeal seeding by systemic cancer

    A two-year-old, female Chinese shar pei was presented with a one-year history of ataxia involving the pelvic limbs. The neurological lesion was localized to the thoracolumbar region of the spinal cord. A cyst involving the dorsal subarachnoid space at the level of the 12th thoracic vertebral body was identified with myelography. The diagnosis of a meningeal cyst was made, and surgical treatment consisting of a dorsal laminectomy and cyst fenestration was performed. The pelvic-limb ataxia improved, and the owners considered the dog to be normal three months after surgery. The classification, etiology, clinical signs, diagnostic techniques, treatment, and histology of meningeal cysts are reviewed

    Although there is no documented evidence that tattoo pigments can cause neurological complications, the implications of performing neuraxial anesthesia through tattooed skin are unknown. In this study, we aimed to assess whether spinal puncture performed through tattooed skin of rabbits determines changes over the spinal cord and meninges. In addition, we sought to evaluate the presence of ink fragments entrapped in spinal needles. Thirty-six young male adult rabbits, each weighing between 3400 and 3900 g and having a spine length between 38.5 and 39 cm, were divided by lot into 3 groups as follows: GI, spinal puncture through tattooed skin; GII, spinal puncture through tattooed skin and saline injection; and GIII, spinal puncture through skin free of tattoo and saline injection. After intravenous anesthesia with ketamine and xylazine, the subarachnoid space was punctured at S1-S2 under ultrasound guidance with a 22-gauge 2½ Quincke needle. Animals in GII and GIII received 5 μL/cm of spinal length (0.2 mL) of saline intrathecally. In GI, the needle tip was placed into the yellow ligament, and no solution was injected into the intrathecal space; after tattooed skin puncture, 1 mL of saline was injected through the needle over a histological slide to prepare a smear that was dyed by the Giemsa method to enable tissue identification if present. All animals remained in captivity for 21 days under medical observation and were killed by decapitation. The lumbosacral spinal cord portion was removed for histological analysis using hematoxylin-eosin stain. None of the animals had impaired motor function or decreased nociception during the period of clinical observation. None of the animals from the control group (GIII) showed signs of injuries to meninges. In GII, however, 4 animals presented with signs of meningeal injury. The main histological changes observed were focal areas of perivascular lymphoplasmacyte infiltration in the pia mater and arachnoid. There was no

    To determinate the potential clinical and histological changes due the injection of betamethasone, when administered into the canine intrathecal space. Twenty one animals were included in a random and blind manner in the study. After general anesthesia, intrathecal puncture was performed and 1 ml of the random solution was injected. The G1 dogs received 0.9% saline solution, the G2 dogs received 1.75 mg betamethasone and the G3 dogs received 3.5 mg of betamethasone. The animals were clinically evaluated for 21 days and then sacrificed. The lumbar and sacral portions of the spinal cord were removed for light microscopy histological analyses. No clinical changes were observed in any of the animals included in this study. No histological changes were observed in G1 animals. Inflammatory infiltration was observed in two dogs, one in G2, another in G3. Hemorrhage and necrosis were also seen in the G2 dog which inflammatory infiltration was detected. In other two dogs, one from G2 and another from G3, there was discreet fibrosis and thickness of the arachnoid layer which was focal in one and diffuse in the other. Intrathecal administration of betamethasone caused histological changes in the spinal cord and meninges in some of the dogs involved in this study.

  14. A novel immune-to-CNS communication pathway: cells of the meninges surrounding the spinal cord CSF space produce proinflammatory cytokines in response to an inflammatory stimulus.

    Pain is enhanced in response to elevations of proinflammatory cytokines in spinal cerebrospinal fluid (CSF), following either intrathecal injection of these cytokines or intrathecal immune challenge with HIV-1 gp120 that induces cytokine release. Spinal cord glia have been assumed to be the source of endogenous proinflammatory cytokines that enhance pain. However, assuming that spinal cord glia are the sole source of CSF cytokines may be an underestimate, as the cellular composition of the meninges surrounding the spinal cord CSF space includes several cell types known to produce proinflammatory cytokines. The present experiments provide the first investigation of the immunocompetent nature of the spinal cord meninges. Here, we explore whether rat meninges are responsive to intrathecal gp120. These studies demonstrate that: (a) intrathecal gp120 upregulates meningeal gene expression of proinflammatory signals, including tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), interleukin 6 (IL-6), and inducible nitric oxide synthase (iNOS), and (b) intrathecal gp120 induces meningeal release of TNF-alpha, IL-1beta, and IL-6. In addition, stimulation of isolated meninges in vitro with gp120 induced the release of TNF-alpha and IL-1beta, indicating that the resident cells of the meninges are able to respond without immune cell recruitment. Taken together, these data document that the meninges are responsive to immunogenic stimuli in the CSF and that the meninges may be a source of immune products detected in CSF. The ability of the meninges to release to proinflammatory signals suggests a potential role in the modulation of pain.

    The extramedullar meningeal cysts are congential anomalies of the spinal canal. The neurological manifestation - the syndromes of radicular pain and the dysfunctions of the pelvic organs are indicators for the neurosurgical treatment. The most complete classification of distinguish the different types of these anomalies is the Nabor's classification. The congential anomalies (malformations) are conventionally diagnosed by TC or conventional MR imaging techniques. These methods can't give a precise answer to the Nabor's classification. The new MR sequences offer the possibility to diagnose these anomalies more precisely. Purpose: to create a new MR protocol for a precise topical diagnostic of the meningeal cysts according to the contemporary embriogenetical, neurological and neurosurgical classification. Conclusions: For the optimal topographical visualisation of the congential spinal meningeal cysts MR in 3 orthogonal planes must be performed. The thin slice techniques with the specific parameters for better visualisation of the nerve roots are necessary. The thin slice, fat suppressed MR sequences are very important for the differential diagnosis of the extradural meningeal cysts from the dermoids, para- and infraspinal fat collections. They are very useful in choosing the optimal microneurosurgical way of the surgical treatment. (authors)

    To evaluate the effect of ketamine S (+) 5% with no preservatives and administered as a subarachnoid single puncture on the spinal cord and meninges of rabbits. Twenty young adult female rabbits, each weighing 3500-5000 g and having a spine length between 34 and 38 cm, were divided by lot into two groups (G): 0.9% saline in G1 and ketamine S (+) 5% in G2, by volume of 5 μg per cm column (0.18 mL). After intravenous anaesthesia with ketamine and xylazine, the subarachnoid space was punctured at S1-S2 under ultrasound guidance, and a random solution was injected. The animals remained in captivity for 21 days under medical observation and were sacrificed by decapitation. The lumbosacral spinal cord portion was removed for immunohistochemistry to assess the glial fibrillary acidic protein (GFAP), and histology was assessed using hematoxylin and eosin (HE) stain. No histological lesions were found in the nervous tissue (roots and cord) or meninges in either group. The ketamine S (+) 5% unpreserved triggered no neurological or histological lesions in the spinal cord or meninges of rabbits.

  17. Myelin basic protein determination in cerebro-spinal fluid of children with tuberculous meningitis

    1986-01-01

    Myelin basic protein (MBP), an indicator of neural tissue damage in cerebro-spinal fluid, was studied in patients with tuberculous meningitis (TBM). MBP levels were elevated in 62% of the cases of TBM, the levels being 13.3+-18.8 ng/mL, compared with control levels of 1.34+-0.55 ng/mL(p<0.001). MBP level was related to certain clinical features of the disease, such as level of consciousness, neurological characteristics associated with signs of raised intracranial tension and the presence of arteritis associated with hydrocephalus. However, its greatest significance was its correlation with the progress of disease. Persistence of high levels of MBP over a period of a few weeks was associated with little or no improvement in the clinical state of the patient or a higher mortality rate. Return to normal levels of MBP indicated a more favourable outcome of disease. Hence MBP estimation gave not only an indicator of the degree of neurological damage but also an important marker to evaluate patients' progress and response to treatment. (author)

  18. Orbital melanocytoma: When a tumor becomes a relieving surprise

    2018-06-01

    Full Text Available Purpose: Melanocytomas are rare pigmented tumors that arise form melanocytes and have been reported in the central nervous system. Orbital melanocytomas “also known as blue nevus” are rarely reported. The occurrence of choroidal melanoma and orbital melanocytomas has never been described. Observations: This is a case of orbital melanocytoma in a 34 year old female who presented with left proptosis and ecchymosis. She has the right eye enucleated to treat a large choroidal melanoma, 6 years earlier. Orbital metastasis was suspected. After orbital imaging and systemic evaluation, incisional biopsy was planned yet the mass could be totally excised and it turned out to be melanocytoma. The condition was not associated with nevus of Ota and the patient is not known to have any predisposing condition for melanocytic lesions. Conclusion and importance: Melanocytoma and malignant melanoma share the same cell of origin. The benign course, the well differentiated cells, absence of anaplasia and the positive reaction to Human Melanoma Black-45 (HMB-45 and S-100 proteins established the diagnosis of the former. Such diagnosis was a relief for this one eyed patient.(HMB-45:human melanoma black-45. Keywords: Orbit, Melanocytoma, Choroidal melanoma, HMB-45, S-100

    Full Text Available The occipital condyle fracture is rare injury of the craniocervical junction. Meningeal spinal cysts are rare tumors of the spinal cord. Depending on location, these lesions may be classified as extradural and subdural, but extradural spinal cysts are more common. We present the case of a 15-year-old girl who suffered from avulsion occipital condyle fracture treated with use of “halo-vest” system. We established that clinical effect after completed treatment is very good. Control MRI evaluation was performed 12 months after removal of “halo-vest” traction, and clinically silent extradural meningeal spinal cysts were detected at the ventral side of the spinal cord in the cervical segment of the spine. Due to clinically silent course of the disease, we decided to use the conservative treatment. The patient remains under control of our department.

    The N-methyl-d-aspartate receptor antagonist ketamine and its active enantiomer, S(+)-ketamine, have been injected in the epidural and subarachnoid spaces to treat acute postoperative pain and relieve neuropathic pain syndrome. In this study we evaluated the effects of a single dose of preservative-free S(+)-ketamine, in doses usually used in clinical practice, in the spinal cord and meninges of dogs. Under anesthesia (IV etomidate (2 mg/kg) and fentanyl (0.005 mg/kg), 16 dogs (6 to 15 kg) were randomized to receive a lumbar intrathecal injection (L5/6) of saline solution of 0.9% (control group) or S(+)-ketamine 1 mg/kg(-1) (ketamine group). All doses were administered in a volume of 1 mL over a 10-second interval. Accordingly, injection solution ranged from 0.6% to 1.5%. After 21 days of clinical observation, the animals were killed; spinal cord, cauda equina root, and meninges were removed for histological examination with light microscopy. Tissues were examined for demyelination (Masson trichrome), neuronal death (hematoxylin and eosin) and astrocyte activation (glial fibrillary acidic protein). No clinical or histological alterations of spinal tissue or meninges were found in animals from either control or ketamine groups. A single intrathecal injection of preservative-free S(+)-ketamine, at 1 mg/kg(-1) dosage, over a concentration range of 6 to 15 mg/mL injected in the subarachnoid space in a single puncture, did not produce histological alterations in this experimental model.

    Full Text Available Patient L.I., aged 47 years, with multiple hospitalizations in November 2013 for multiple neurological and infectious diseases. In October 2011, surgery was performed for vicious posttraumatic right acetabular callus, confirmed by computed tomography. Subsequently, in November 2013, the patient had lumbar pain radiating to the lower limbs, functional impotence, sphincter incontinence, septic state with positive hemocultures for Staphylococcus aureus, with multiple paravertebral abscesses involving the left iliopsoas muscle, confirmed by contrast magnetic resonance imaging of the dorsolumbar spine, operated phlegmon of the left leg, which were interpreted as diffuse secondary spinal meningitis, complicated by a cauda equina syndrome, for which adequate antibiotic treatment was administered at the Clinic of Infectious Diseases Cluj-Napoca. The patient also presented two episodes of Clostridium difficile acute enterocolitis, with two fecal transplant sessions. In May 2014, the patient was admitted to the Rehabilitation Hospital Cluj-Napoca for motor deficit of the lower limbs, walking disorders, micturition disorders, sexual dynamic disorders, pain in the lumbar spine radiating to the lower limbs, sudden onset sensitivity disorders at D10 level in a febrile context in November 2013, interpreted based on lumbar MRI as spinal meningitis secondary to dorsal and lumbar paravertebral abscesses. During the course of hospitalization, the patient received a complex medical rehabilitation treatment consisting of kinetotherapy (posturations, passive mobilizations, active mobilizations, transfers, proprioceptive neuromuscular facilitation techniques, walking rehabilitation, respiratory gymnastics, rehabilitation of sensitivity disorders, occupational therapy, massage, medium frequency currents for the rehabilitation of micturition disorders, with good results particularly in walking and urinary incontinence rehabilitation.

    A 7-year-old gray Mustang gelding weighing 454 kg was presented for evaluation of a brown mass within the left eye (OS) of 1 year's duration with recent enlargement. A nonpainful, 8 mm diameter, brown, vascularized mass was identified in the anterior chamber of the OS. Ocular B-scan ultrasound confirmed iris involvement and corneal endothelial contact. Histopathology confirmed the presumptive diagnosis of a uveal melanocytic neoplasm, and revealed 1-3 mitotic figures per high power (400x) field. The mass was removed via sector iridectomy without complications, but without complete margins. Three cutaneous melanocytomas noted 1.5 months postoperatively were completely excised. No tumor regrowth was noted 15 months postoperatively, supporting a diagnosis of melanocytoma for the iridal mass. Sector iridectomy is a reasonable treatment option for uncomplicated iridal melanocytomas in horses. Mitotic index and presence of cutaneous melanocytic neoplasms may be irrelevant to the prognosis of equine iridal melanocytic neoplasms.

    2015-10-01

    A 60-year old patient was referred for cataract surgery. The examination showed retrokeratic pigment in the left eye, which had an intraocular pressure of 24 mm Hg. The funduscopy showed a brown lesion on the left optic disk, with adjacent vitreous seeding of pigment. The patient was thus diagnosed with secondary pigment dispersion syndrome due to optic disk melanocytoma. Although melanocytoma is most commonly a benign, stationary tumor, it may present with major complications leading to significant visual loss. A patient with melanocytoma of the optic disk should be examined periodically. Copyright © 2014 Sociedad Española de Oftalmología. Published by Elsevier España, S.L.U. All rights reserved.

  4. A New Classification for Pathologies of Spinal Meninges-Part 2: Primary and Secondary Intradural Arachnoid Cysts.

    2017-08-01

    Spinal intradural arachnoid cysts are rare causes of radiculopathy or myelopathy. Treatment options include resection, fenestration, or cyst drainage. To classify intradural spinal arachnoid cysts and present results of their treatment. Among 1519 patients with spinal space occupying lesions, 130 patients demonstrated intradural arachnoid cysts. Neuroradiological and surgical features were reviewed and clinical data analyzed. Twenty-one patients presented arachnoid cysts as a result of an inflammatory leptomeningeal reaction related to meningitis, subarachnoid hemorrhage, intrathecal injections, intradural surgery, or trauma, ie, secondary cysts. For the remaining 109 patients, no such history could be elucidated, ie, primary cysts. Forty-six percent of primary and 86% of secondary cysts were associated with syringomyelia. Patients presented after an average history of 53 ± 88 months. There were 122 thoracic and 7 lumbar cysts plus 1 cervical cyst. Fifty-nine patients with primary and 15 patients with secondary cysts underwent laminotomies with complete or partial cyst resection and duraplasty. Mean follow-up was 57 ± 52 months. In the first postoperative year, profound improvements for primary cysts were noted, in contrast to marginal changes for secondary cysts. Progression-free survival for 10 years following surgery was determined as 83% for primary compared to 15% for secondary cysts. Despite differences in clinical presentation, progression-free survival was almost identical for patients with or without syringomyelia. Complete or partial resection leads to favorable short- and long-term results for primary arachnoid cysts. For secondary cysts, surgery can only provide clinical stabilization for a limited time due to the often extensive arachnoiditis. Copyright © 2017 by the Congress of Neurological Surgeons

    The clinical significance of pathologies of the spinal dura is often unclear and their management controversial. To classify spinal dural pathologies analogous to vascular aneurysms, present their symptoms and surgical results. Among 1519 patients with spinal space-occupying lesions, 66 patients demonstrated dural pathologies. Neuroradiological and surgical features were reviewed and clinical data analyzed. Saccular dural diverticula (type I, n = 28) caused by defects of both dural layers, dissections between dural layers (type II, n = 29) due to defects of the inner layer, and dural ectasias (type III, n = 9) related to structural changes of the dura were distinguished. For all types, symptoms consisted of local pain followed by signs of radiculopathy or myelopathy, while one patient with dural ectasia presented a low-pressure syndrome and 10 patients with dural dissections additional spinal cord herniation. Type I and type II pathologies required occlusion of their dural defects via extradural (type I) or intradural (type II) approaches. For type III pathologies of the dural sac no surgery was recommended. Favorable results were obtained in all 14 patients with type I and 13 of 15 patients with type II pathologies undergoing surgery. The majority of dural pathologies involving root sleeves remain asymptomatic, while those of the dural sac commonly lead to pain and neurological symptoms. Type I and type II pathologies were treated with good long-term results occluding their dural defects, while ectasias of the dural sac (type III) were managed conservatively.

    Following epidural administration, cerebrospinal fluid bioavailability of local anesthetics is low, one major limiting factor being diffusion across the arachnoid mater barrier. The aim of this study was to evaluate the influence of absorption enhancers on the meningeal permeability of epidurally administered ropivacaine. Five enhancers known for their ability to increase drug permeability via transcellular and/or paracellular pathways, i.e. palmitoyl carnitine, ethylenediaminetetraacetic acid, sodium caprate, dodecylphosphocholine and pentylglycerol, were tested ex vivo on fresh specimen of meninges removed from cervical to lumbar level of rabbit spine following laminectomy and placed in diffusion chambers. Among them, sodium caprate lead to the best permeability improvement for both marker and drug (440% and 112% for mannitol and ropivacaine, respectively) and was therefore selected for in vivo study in a sheep model using microdialysis technique to evaluate epidural and intrathecal ropivacaine concentrations following epidural administration. Resulting dialysate and plasma concentrations were used to calculate pharmacokinetic parameters. Following sodium caprate pre-treatment, ropivacaine intrathecal maximal concentration (Cmax) was 1.6 times higher (78 ± 16 μg ml(-1) vs 129 ± 26 μg ml(-1), p<0.05) but the influence of the absorption enhancer was only effective the first 30 min following ropivacaine injection, as seen with the significantly increase of intrathecal AUC(0-30 min) (1629 ± 437 μg min ml(-1) vs 2477 ± 559 μg min ml(-1), p<0.05) resulting in a bioavailable fraction 130% higher 30 min after ropivavaine administration. Co-administration of local anesthetics with sodium caprate seems to allow a transient and reversible improvement of transmeningeal passage into intrathecal space. Copyright © 2010 Elsevier B.V.

  16. The concentration of CYFRA 21-1, NSE and CEA in cerebro-spinal fluid can be useful indicators for diagnosis of meningeal carcinomatosis of lung cancer.

    Wang, Peng; Piao, Yingzhe; Zhang, Xiaohui; Li, Wenliang; Hao, Xishan

    2013-01-01

    We aimed to investigate the concentration of CYFRA 21-1, NSE and CEA in cerebro-spinal fluid (CSF) and to explore their clinical value in the meningeal carcinomatosis (MC) of lung cancer. So that, sensitive and specificity of CSF examination can be improved in the initial diagnosis of MC. A total of 35 lung cancer patients and 35 patients with benign brain tumor in the same period enrolled in this study. The concentrations of tumor markers CEA, CYFRA 21-1 and NSE in CSF and peripheral blood were examined. The concentrations of three tumor markers of CYFRA 21-1, NSE and CEA in blood serum and CSF were obviously higher than that of benign disease group. In MC patients, the concentrations of three tumor markers of CYFRA 21-1, NSE and CEA in blood serum were significant lower than that in CSF. The maximum of Youden's index was identified as the cutoff value of indicator of MC in three tumor markers in CSF which were CEA > 4.7 μg/L, NSE > 14.6 μg/L and CYFRA21-1 > 5.5 μg/L respectively. Based on the cutoff values, the CEA had the highest sensitivity while the CYFRA21-1 had the highest specificitiy. Three tumor markers in the CSF had higher positive rate than those in blood serum. We combined the levels of CEA, NSE and CYFRA21-1 in CSF to diagnosis of MC. Positive of CEA or CYFRA21-1 had the greatest sensitivity of 100% while the specificity of 91.4%; the positive of both CEA and CYFRA21-1 had the highest specificity of 100% while the sensitivity of 74.3%. Both positive predictive value and negative predictive value were 100% when combination positive were confirmed when the all three markers were positive. The combination of CEA and CYFRA21-1 can be recommended in early screening of meningeal carcinoma. Especially, for the patient who was difficult to be diagnosed by CSF histology and MRI, it will be a useful auxiliary marker in diagnosis of MC. The combination of CEA, NSE and CYFRA21-1 can be an effective clinically confirmation and exclusively diagnose indictor of

  17. Recurrent Meningitis.

    Rosenberg, Jon; Galen, Benjamin T

    2017-07-01

    Recurrent meningitis is a rare clinical scenario that can be self-limiting or life threatening depending on the underlying etiology. This review describes the causes, risk factors, treatment, and prognosis for recurrent meningitis. As a general overview of a broad topic, the aim of this review is to provide clinicians with a comprehensive differential diagnosis to aide in the evaluation and management of a patient with recurrent meningitis. New developments related to understanding the pathophysiology of recurrent meningitis are as scarce as studies evaluating the treatment and prevention of this rare disorder. A trial evaluating oral valacyclovir suppression after HSV-2 meningitis did not demonstrate a benefit in preventing recurrences. The data on prophylactic antibiotics after basilar skull fractures do not support their use. Intrathecal trastuzumab has shown promise in treating leptomeningeal carcinomatosis from HER-2 positive breast cancer. Monoclonal antibodies used to treat cancer and autoimmune diseases are new potential causes of drug-induced aseptic meningitis. Despite their potential for causing recurrent meningitis, the clinical entities reviewed herein are not frequently discussed together given that they are a heterogeneous collection of unrelated, rare diseases. Epidemiologic data on recurrent meningitis are lacking. The syndrome of recurrent benign lymphocytic meningitis described by Mollaret in 1944 was later found to be closely related to HSV-2 reactivation, but HSV-2 is by no means the only etiology of recurrent aseptic meningitis. While the mainstay of treatment for recurrent meningitis is supportive care, it is paramount to ensure that reversible and treatable causes have been addressed for further prevention.

    The authors report fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (OCT) findings of two consecutive patients who presented with optic disk melanocytoma (ODM). A retrospective study was performed by reviewing medical records and ophthalmic imaging examinations. Optical coherence tomography findings were sloped and brightly reflective anterior tumor surface, adjacent retinal desorganization and abrupt posterior optical shadowing. Vitreous seeds were found in one patient. Fundus autofluorescence revealed outstanding hypoautofluorescence at the tumor area and isoautofluorescence at the remaining retina. Optical coherence tomography findings of the reported cases are consistent with those reported in the reviewed literature. Fundus autofluorescence has been used in the assessment of choroidal melanocytic tumors, but not yet in melanocytomas. We assume that this is the first report of these findings and believe that when its pattern has become clearly defined, fundus autofluorescence will be a useful tool to avoid misdiagnosis in suspicious cases and for follow-up.

    The ratio between concentrations of 82 Br in serum and spinal fluid was determined in patients with meningitis. The ratio was found to be low in three patients strongly suspect for tuberculous meningitis and in eight of nine patients with purulent meningitis, but normal in 13 patients with non-tuberculous, serous meningitis. These results confirm previous investigations and determination of the 82 Br ratio is a simple, reliable aid in the diagnosis of tuberculous meningitis. (author)

  6. Meninges-derived cues control axon guidance.

    Suter, Tracey A C S; DeLoughery, Zachary J; Jaworski, Alexander

    2017-10-01

    The axons of developing neurons travel long distances along stereotyped pathways under the direction of extracellular cues sensed by the axonal growth cone. Guidance cues are either secreted proteins that diffuse freely or bind the extracellular matrix, or membrane-anchored proteins. Different populations of axons express distinct sets of receptors for guidance cues, which results in differential responses to specific ligands. The full repertoire of axon guidance cues and receptors and the identity of the tissues producing these cues remain to be elucidated. The meninges are connective tissue layers enveloping the vertebrate brain and spinal cord that serve to protect the central nervous system (CNS). The meninges also instruct nervous system development by regulating the generation and migration of neural progenitors, but it has not been determined whether they help guide axons to their targets. Here, we investigate a possible role for the meninges in neuronal wiring. Using mouse neural tissue explants, we show that developing spinal cord meninges produce secreted attractive and repulsive cues that can guide multiple types of axons in vitro. We find that motor and sensory neurons, which project axons across the CNS-peripheral nervous system (PNS) boundary, are attracted by meninges. Conversely, axons of both ipsi- and contralaterally projecting dorsal spinal cord interneurons are repelled by meninges. The responses of these axonal populations to the meninges are consistent with their trajectories relative to meninges in vivo, suggesting that meningeal guidance factors contribute to nervous system wiring and control which axons are able to traverse the CNS-PNS boundary.

  12. Diskitis, Osteomyelitis, Spinal Epidural Abscess, Meningitis, and Endocarditis Following Sacroiliac Joint Injection for the Treatment of Low-Back Pain in a Patient on Therapy for Hepatitis C Virus.

    Nagpal, Geeta; Flaherty, John P; Benzon, Honorio T

    Sacroiliac joint injections are frequently performed procedures in the management of acute and chronic low-back pain, including patients with various immunocompromised states. Infectious complications following these procedures along with other spinal injections are rarely reported, but the true incidence is unknown. The purpose of this report is to highlight the devastating neurologic sequela that can occur, and to discuss potential future management strategies. We present a patient who developed diskitis, osteomyelitis, spinal epidural abscess, meningitis, and endocarditis from Staphylococcus aureus, all of which developed shortly after a sacroiliac joint injection. The patient was on treatment for hepatitis C virus, and the resulting immunocompromised state likely contributed to the outcome. Immunocompromised patients should be identified prior to treatment, and the small possibility of devastating complications should be thoughtfully weighed against the potential benefit of the procedure. Conservative management should be maximized initially, and if a procedure is done, strict asepsis must be maintained. Prophylaxis for S. aureus should be considered for immunocompromised patients undergoing interventional spine procedures.

  13. A Case of Iris Melanocytoma Demonstrating Diffuse Melanocytic Proliferation with Uncontrolled Intraocular Pressure

    Mami Kusunose

    2017-03-01

    Full Text Available We report a rare case with histologically proven melanocytoma of the iris that demonstrated diffuse melanocytic proliferation with uncontrolled secondary glaucoma and investigate the etiology of the intraocular pressure elevation. The patient was a 78-year-old man with a history of darkened iris of his left eye. The intraocular pressure was 39 mm Hg. A slit-lamp examination showed a diffuse darkened iris, and a gonioscopic examination revealed open angle with circumferential heavy pigmentation. There was no pigment dispersion of the anterior chamber and no pigment deposition of the cornea. We suspected malignant ring melanoma in the left eye and enucleated it. The globe was examined with light and electron microscopy. Light microscopy revealed the presence of heavily pigmented tumor cells in the iris, ciliary body, trabecular meshwork, and Schlemm’s canal. A bleached preparation showed large tumor cells with central and paracentral nuclei without mitosis. Electron microscopy of the trabecular meshwork revealed melanin-bearing tumor cells invading the intertrabecular spaces, and the melanin granules were not phagocytosed in the trabecular cells. The mechanical obstruction of the aqueous flow by the tumor cells may be a major cause of secondary glaucoma in eyes with iris melanocytoma presenting diffuse proliferation.

  14. Does antimicrobial usage before meningitis lead to a higher risk of adult postsurgical Acinetobacter baumannii meningitis than that of Enterobacteriaceae meningitis?

    Demiraslan, Hayati; Ulutabanca, Halil; Ercal, Baris Derya; Metan, Gokhan; Alp, Emine

    2016-12-01

    Acinetobacter baumannii and Enterobacteriaceae are two pathogens responsible for postneurosurgical meningitis. The aim of this retrospective study was to evaluate the factors that influenced the outcomes in patients with postneurosurgical meningitis caused by A. baumannii and Enterobacteriaceae. Patients with post-surgical meningitis were identified from infection control committee charts between 2007 and 2015. Subjects over 16 years old who had positive cerebral spinal fluid cultures for A. baumannii or Enterobacteriaceae were enrolled in the study. Clinical and laboratory data for 30 patients with A. baumannii meningitis were compared with those of 12 patients with Enterobacteriaceae meningitis. The mean age of patients was 51.9 years and 57.1% were male. Eleven patients had comorbidities, the most common being diabetes mellitus. Most patients were due to intracranial haemorrhage (78.6%). The rate of the patients who received an appropriate antimicrobial therapy was 35.7%, and the crude mortality rate was 64.3%. In univariate analysis, previous antibiotic use, an infection before meningitis and mechanical ventilation had an increased risk of A. baumannii meningitis. Moreover, intrathecal antimicrobial use, inappropriate empirical antimicrobial use, antimicrobial resistance and alanine aminotransferase elevation were significantly higher in patients with A. baumannii meningitis than in those with Enterobacteriaceae meningitis. Antimicrobial use before meningitis (8.84 times) and mechanical ventilation (7.28 times) resulted in an increased risk of A. baumannii meningitis. None of the results affected 30-day mortality. Avoidance of unnecessarily prolonged antimicrobial usage may help to prevent a selection of A. baumannii.

    2015-03-01

    Full Text Available Objective To investigate the clinical, neuroimaging and pathological features of meningeal hemangiopericytoma.  Methods One case of meningeal hemangiopericytoma was reported, and the relevant literatures were also reviewed.  Results A 40-year-old male had caught a headache for about 3 months with muscle weakness in the left limb, and became progressively serious for 2 weeks. Brain MRI displayed a space-occupying lesion in the right temporal lobe with equal signals in T1WI, mixed signals in T2WI and obvious enhancements. In surgery, the tumor was found to be located in the cranial fossa, and was completely removed. The tumor was large, with rich blood supply, and had no capsule. In histology, the neoplasm was composed of dense spindle cells with mild atypia. The boundary of the tumor cells was unclear. The nuclei were circular, oval or spindle with obvious mitoses (4/10 HPF. There were plenty of thick-wall blood vessels and blood sinuses with characteristic "staghorn" shape. In immunohistochemistry, CD34 and vimentin (Vim were positive, epithelial membrane antigen (EMA was focally positive and Ki-67 labeling index was 17%-20%. Postoperative radiotherapy was adopted and no relapse was found during the 20-month follow-up period. Conclusions The meningeal hemangiopericytoma is easy to be misdiagnosed as meningioma, however, the prognosis of meningeal hemangiopericytoma is quite worse, thus the differential diagnosis is very important. A clear diagnosis often depends on pathological examination. DOI: 10.3969/j.issn.1672-6731.2015.03.011

    Carcinomatous meningitis is a serious complication of advanced stage solid tumours, which may become more common with improved survival. A 53-year-old woman with a recent history of breast cancer (pT2pN2M0) had been treated by mastectomy and adjuvant chemotherapy and radiotherapy. She presented with weakness, diplopia and vertigo raising the possibility of vertebrobasilar ischaemia or an intracranial mass. In another patient, a 62-year-old man with hypertension, a stenotic common bile duct had been diagnosed when examined for abdominal complaints. When he presented with a high blood pressure value accompanied by intensive headache, vomiting and bilateral hearing loss, he was thought to have a hypertensive crisis. The rapidly progressive neurological symptoms and the history of breast cancer and findings suggesting pancreatic head tumour, respectively, led to the clinical diagnosis of carcinomatous meningitis in both cases, despite any evidence on CT scans or a negative MR scan, though of limited value, in the first case. This diagnosis was confirmed by the laboratory and cytological findings of the cerebrospinal fluid, and also by the post mortem examination, since both patients died within a month after the onset of the symptoms. The primary tumour in the second patient proved to be a widely metastasizing diffuse type gastric cancer. Carcinomatous meningitis has a varying but characteristic presentation which generally makes it easy to diagnose, but it can sometimes present differential diagnostic problems. What we can learn from these two cases may help in recognizing this complication.

  17. Recurrent meningitis--a review of current literature.

    Janocha-Litwin, Justyna; Simon, Krzysztof

    2013-01-01

    The paper discusses epidemiology, aetiology and the most important predisposing factors associated with recurrent meningitis, as well as the possibilities to prevent this particularly challenging clinical problem. The frequency of recurrent meningitis is estimated to be 2-9%. However, the case fatality is lower compared to a single episode of meningitis. The main causes of recurrent meningitis are considered to be: head injury, congenital or acquired (post-traumatic or post-surgical) cranial or spinal defects, chronic intracranial inflammation, complement system dysfunction, as well as congenital and acquired humoral or cellular immunodeficiency.

  18. Melanocitoma do nervo óptico Optic disk melanocytoma: bibliographic review

    Full Text Available O melanocitoma do disco óptico é bem conhecido como uma variante do nervo melanocítico que geralmente ocorre no disco óptico. Historicamente o tumor foi confundido com melanoma maligno. Histopatologicamente é composto por células redondas densamente pigmentadas com citoplasma abundante e pequenos nucléolos. O melanocitoma é considerado um tumor benigno, estacionário e com pouca predisposição de sofrer malignação. Na maioria dos casos são assintomáticos, mas podem apresentar defeitos pupilares e no campo visual. É importante salientar que a transformação maligna em melanoma ocorre em 1 a 2% dos casos. Assim, os oftalmologistas devem familiarizar-se com o melanocitoma do disco óptico e os pacientes afetados devem ser acompanhados periodicamente.Melanocytoma of the optic disc is a well known variant of melanocytic nevus that usually occurs as a deeply pigmented lesion on the head of the optic disc. Historically, this tumor has often been confused with malignant melanoma. Histopathologically, it is composed of deeply pigmented round oval cells with abundant cytoplasm and small, round, bland nuclei. Melanocytomas is a benign, stationary tumors, with almost no propensity to undergo malignant transformation. Most cases that occur on the optic disc are visually asymptomatic, but they can cause an afferent pupillary and visual field defects. Importantly, it can exhibit malignant transformation into melanoma in 1 to 2% of the cases. The affected patients should have periodic follow up.

    The recent discovery of meningeal lymphatic vessels (LVs) has raised interest in their possible involvement in neuropathological processes, yet little is known about their development or maintenance. We show here that meningeal LVs develop postnatally, appearing first around the foramina in the basal parts of the skull and spinal canal, sprouting along the blood vessels and cranial and spinal nerves to various parts of the meninges surrounding the central nervous system (CNS). VEGF-C, expressed mainly in vascular smooth muscle cells, and VEGFR3 in lymphatic endothelial cells were essential for their development, whereas VEGF-D deletion had no effect. Surprisingly, in adult mice, the LVs showed regression after VEGF-C or VEGFR3 deletion, administration of the tyrosine kinase inhibitor sunitinib, or expression of VEGF-C/D trap, which also compromised the lymphatic drainage function. Conversely, an excess of VEGF-C induced meningeal lymphangiogenesis. The plasticity and regenerative potential of meningeal LVs should allow manipulation of cerebrospinal fluid drainage and neuropathological processes in the CNS. © 2017 Antila et al.

  2. Imaging procedures in spinal infectious diseases

    2001-01-01

    A targeted successful treatment of spinal infectious diseases requires clinical and laboratory data that are completed by the contribution of imaging procedures. Neuroimaging only provides essential informations on the correct topography, localisation, acuity and differential diagnosis of spinal infectious lesions. MRI with its sensitivity concerning soft tissue lesions is a useful tool in detecting infectious alterations of spinal bone marrow, intervertebral disks, leptomeninges and the spinal cord itself. Crucial imaging patterns of typical spinal infections are displayed and illustrated by clinical case studies. We present pyogenic, granulomatous and postoperative variants of spondylodicitis, spinal epidural abscess, spinal meningitis and spinal cord infections. The importance of intravenous contrastmedia application is pointed out. (orig.) [de

  3. Cryptococcal meningitis

    DING Wen-ting

    2013-01-01

    Full Text Available Cryptococcus neoformans is a kind of encapsulated fungal organism that widely exists in the nature. Because of its neurotropic nature, the central nervous system becomes its major target organ. Cryptococcus neoformans can use "transcellular pathway", "paracellular pathway" and "Trojan horse approach" to cross blood-brain barrier, and then make the devastating diffusion. Despite antifungal therapy, the mortality rate remains between 10% and 25% in patients with cryptococcal meningitis (CM and acquired immunodeficiency syndrome (AIDS, and at least one-third of patients have experienced failure of antifungal therapy. Consequently, it is very important for us to understand the pathogenesis of CM, to diagnose as soon as possible and to explore more reasonable treatment.

    Full Text Available Meningitis is an acute inflammation of the protective membranes covering the brain and spinal cord, which are known as the meninges. This infection may be caused by Streptococcus pneumonia bacteria. In this study, we presented the case of a female newborn with meningitis secondary to Streptococcus pneumonia. Her birth weight and height were normal. After 24 hours of birth, the neonate was diagnosed with tachypnea, without presenting any signs of fever or respiratory distress. The newborn was referred to Sheikh Children's Hospital, where chest X-ray showed clear lungs with no evidence of abnormality. Furthermore, the cardiothoracic ratio was normal. A complete blood count demonstrated white blood cell (WBC count of 5400/uL. In Blood/Culcture ratio (B/C test, Streptococcus pneumonia was reported, and the results of the cerebrospinal fluid (CSF analysis confirmed this result. Following 14 days of receiving antibiotic therapy, the results of CSF analysis were within the normal range. Her visual and hearing examinations were normal, and demonstrated improved situation. The infant was discharged with exclusive breastfeeding.

  8. Malignant melanomas of the meninges (MR and CT)

    Schuknecht, B.; Nadjmi, M.; Mueller, J.

    1990-01-01

    Malignant melanoma of the meninges is a rare neoplasm derived from melanocytes of the cranial or spinal meninges. Histologically classified as grade IV tumours, malignant melanoma may present either as a diffuse meningeal neoplasm, first described by Virchow in 1859, or as a circumscribed tumour attached to the meninges. Although diagnosis is rarely established prior to surgery or autopsy, MR and CT may provide indispensable information probably leading to earlier diagnosis. In 4 patients, diagnosis of a primary meningeal melanoma was based on MR and CT findings and histology. Histology was obtained in 3 cases by surgery, in one patient by autopsy and showed a melanotic and an amelanotic malignant melanoma in 2 patients each. Autopsy was carried out in 3 cases after survival of 4, 5, and 18 months; in a single case, the follow-up period is almost 3 years. (orig.) [de

    2017-05-01

    Full Text Available BACKGROUND Meningitis is an infection within the subarachnoid space characterised by a CNS inflammatory reaction. It is a serious condition requiring immediate diagnosis and appropriate treatment to be started at the earliest to prevent mortality as well as irreversible neurological deficits. CSF lactate has been found useful in differentiating bacterial meningitis from viral meningitis in many studies in the western population, but studies in Indian population are limited. The aim of the study is to study whether CSF lactate can be used to distinguish bacterial from viral meningitis and to study the levels of CSF lactate in tuberculosis meningitis. MATERIALS AND METHODS This was a descriptive study conducted in a tertiary care hospital. In this study, 78 cases of meningitis were selected. Cases are patients with bacterial, viral or tuberculosis meningitis admitted to the hospital under the Department of Medicine and Neurology. Cases are grouped into bacterial, viral and tuberculosis meningitis based on clinical picture, CSF analysis and imaging characteristics. CSF lactate estimation was done by dry chemistry method. Using appropriate statistical methods and SPSS software, CSF lactate levels were compared among these groups and analysed for any association with the final outcome. RESULTS The levels of CSF lactate in bacterial meningitis were higher than viral meningitis with a statistical significance of p 35 mg/dL for bacterial meningitis in this study was 95% and 100% respectively and the positive predictive value was 100% and the negative predictive value was 96%. The mean CSF lactate values in bacterial, viral and tuberculosis meningitis were 124.40 ± 35.85 mg/dL, 24.34 ± 6.05 mg/dL and 50.13 ± 9.89 mg/dL, respectively. CONCLUSION CSF lactate level was significantly elevated in bacterial meningitis than tuberculosis or viral meningitis and can be used as a marker for differentiating bacterial from viral meningitis.

    2009-01-01

    Objective: To investigate the pathway and MRI findings of meningeal metastasis original from lung cancer. Methods: 44 cases with cerebro-spinal meningeal metastasis original from lung cancer proven by clinical and pathology were retrospectively reviewed. All cases undergone plain MRI scan and Gd-DTPA enhanced MRI scan on brain and/or spine. Results: MRI plain scan indicated 28 cases with brain metastases, 3 cases with meningeal nodosity or irregularly patchy abnormal signal, 1 case with nodule in left cavernous sinus, 10 cases with abnormal signal in spine, 2 cases with abnormal signal in spinal dura mater. 34 cases with cerebro meningeal metastases were found in MRI enhancement scan. Among them, 11 cases displayed cerebral dura mater-arachnoid enhancement, 17 cases revealed cerebral pia mater-arachnoid enhancement and 6 cases with mixed typed enhancement. Osteoclasia in skull was found in 4 cases, spinal metastasis was revealed in 17 cases, and patchy abnormal enhancement in spinal dura mater was showed in 12 cases. Conclusion: Hematogenous metastasis is a main route of meningeal metastasis caused by lung cancer and enhanced MRI scan is of important diagnostic value. (authors)

    Drug-induced aseptic meningitis is a rare adverse effect of some drugs. We report a patient with four episodes of meningitis caused by ibuprofen. In all episodes the patient had taken ibuprofen for pain, and subsequently developed fever and cerebrovascular symptoms. Drug-induced meningitis cannot...... be distinguished from meningitis caused by other agents. Diagnosis is therefore based on close association between drug administration and onset of symptoms, as well as negative microbiology tests results, especially if previous episodes of drug-induced meningitis have occurred....

  12. MRI Findings of Early-Stage Hyperacute Hemorrhage Causing Extramedullary Compression of the Cervical Spinal Cord in a Dog with Suspected Steroid-Responsive Meningitis-Arteritis

    Full Text Available A 9-month-old female Weimaraner was presented to the emergency service due to episodes of fever and neck pain. Physical examination revealed a stiff neck posture and elevated body temperature. Shortly after clinical examination was performed, the dog developed peracute onset of non-ambulatory tetraparesis compatible with a C1–C5 spinal cord (SC lesion. Immediately thereafter (<1 h, MRI of the cervical SC was performed with a 3-T scanner. A left ventrolateral intradural-extramedullary SC compression caused by a round-shaped structure at the level of C3––C4 was evidenced. The structure was iso- to slightly hyperintense in T1-weighted (T1W sequences compared to SC parenchyma and hyperintense in T2-weighted, gradient echo, and fluid-attenuated inversion recovery. Moreover, the structure showed a strong homogeneous contrast uptake in T1W sequences. Cerebrospinal fluid (CSF analysis revealed a mixed pleocytosis, as well as elevated protein and erythrocyte count. Early-stage hyperacute extramedullary hemorrhage was suspected due to immune mediated vasculitis. The dog was maintained under general anesthesia and artificial ventilation for 24 h and long-term therapy with corticosteroids and physiotherapy was initiated. Eight weeks after initial presentation, the dog was ambulatory, slightly tetraparetic. Follow-up MRI showed a regression of the round-shaped structure and pleocytosis was not evident in CSF analysis. This report describes an early-stage hyperacute extramedullary hemorrhage, a condition rarely recorded in dogs even in experimental settings.

    Full Text Available AIM: To investigate the findings of infrared fundus autofluorescence (IR-AF and spectral-domain optical coherence tomography (SD-OCT in eyes with optic disc melanocytoma (ODM. METHODS: IR-AF findings and those of other ophthalmologic imaging examinations, including short-wave autofluorescence (SW-AF, fluorescein angiography (FA, fundus color photography, and SD-OCT of 8 eyes of 8 consecutive cases with ODM were assessed. RESULTS: The ODMs in all cases (100% presented similar IR-AF, SW-AF, and FA findings. On IR-AF images, ODMs showed outstanding hyper-AF with well-defined outline. On SW-AF images, the area of ODMs presented as hypo-AF. FA images revealed the leaking retinal telangiectasia on the surface of the ODMs. On SD-OCT images in 8 cases (100%, the ODMs were sloped with highly reflective surface, which were disorganized retina and optic nerve layers. In 7 cases (87.5%, peripapillary choroids were involved. The melanocytomas of 8 cases (100% presented as optically empty spaces. Vitreous seeds were found in one case (12.5%. CONCLUSION: IR-AF imaging may provide a new modality to evaluate the pathologic features of ODMs, and together with SW-AF imaging, offers a new tool to study biological characteristics associated with ODMs. SD-OCT is a valuable tool in delimitating the tumor extension and providing morphological information about the adjacent retinal tissue.

  16. [Meningitis carcinomatosa (author's transl)].

    Steinhäusl, H

    1979-06-20

    On the basis of a case report the clinical picture of meningitis carcinomatosa is discussed. The cerebrospinal fluid is the most important criterion for the diagnosis. All other examinations (EEG, brain-scan, X-ray) yield only imperfect information. The clinical picture of meningitis carcinomatosa is similar above all to meningitis tuberculosa. If cerebrospinal fluid shows inflammatory signs and there is a breakdown of cerebral nerves (blindness, deafness) meningitis carcinomatosa always should be considered, even if thorough examination does not succeed in proving a primary tumour.

  17. The meninges: new therapeutic targets for multiple sclerosis.

    Russi, Abigail E; Brown, Melissa A

    2015-02-01

    The central nervous system (CNS) largely comprises nonregenerating cells, including neurons and myelin-producing oligodendrocytes, which are particularly vulnerable to immune cell-mediated damage. To protect the CNS, mechanisms exist that normally restrict the transit of peripheral immune cells into the brain and spinal cord, conferring an "immune-specialized" status. Thus, there has been a long-standing debate as to how these restrictions are overcome in several inflammatory diseases of the CNS, including multiple sclerosis (MS). In this review, we highlight the role of the meninges, tissues that surround and protect the CNS and enclose the cerebral spinal fluid, in promoting chronic inflammation that leads to neuronal damage. Although the meninges have traditionally been considered structures that provide physical protection for the brain and spinal cord, new data have established these tissues as sites of active immunity. It has been hypothesized that the meninges are important players in normal immunosurveillance of the CNS but also serve as initial sites of anti-myelin immune responses. The resulting robust meningeal inflammation elicits loss of localized blood-brain barrier (BBB) integrity and facilitates a large-scale influx of immune cells into the CNS parenchyma. We propose that targeting the cells and molecules mediating these inflammatory responses within the meninges offers promising therapies for MS that are free from the constraints imposed by the BBB. Importantly, such therapies may avoid the systemic immunosuppression often associated with the existing treatments. Copyright © 2015 Elsevier Inc. All rights reserved.

  18. Stroke in tuberculous meningitis.

    Misra, Usha Kant; Kalita, Jayantee; Maurya, Pradeep Kumar

    2011-04-15

    Stroke in tuberculous meningitis (TBM) occurs in 15-57% of patients especially in advance stage and severe illness. The majority of strokes may be asymptomatic because of being in a silent area, deep coma or associated pathology such as spinal arachnoiditis or tuberculoma. Methods of evaluation also influence the frequency of stroke. MRI is more sensitive in detecting acute (DWI) and chronic (T2, FLAIR) stroke. Most of the strokes in TBM are multiple, bilateral and located in the basal ganglia especially the 'tubercular zone' which comprises of the caudate, anterior thalamus, anterior limb and genu of the internal capsule. These are attributed to the involvement of medial striate, thalamotuberal and thalamostriate arteries which are embedded in exudates and likely to be stretched by a coexistent hydrocephalus. Cortical stroke can also occur due to the involvement of proximal portion of the middle, anterior and posterior cerebral arteries as well as the supraclinoid portion of the internal carotid and basilar arteries which are documented in MRI, angiography and autopsy studies. Arteritis is more common than infarction in autopsy study. The role of cytokines especially tumor necrosis factor (TNFα), vascular endothelial growth factor (VEGF) and matrix metaloproteineases (MMPs) in damaging the blood brain barrier, attracting leucocytes and release of vasoactive autocoids have been suggested. The prothrombotic state may also contribute to stroke in TBM. Corticosteroids with antitubercular therapy were thought to reduce mortality and morbidity but their role in reducing strokes has not been proven. Aspirin also reduces mortality and its role in reducing stroke in TBM needs further studies. Copyright © 2010 Elsevier B.V. All rights reserved.

    1990-02-01

    A 35-year-old woman was treated with intraventricular methotrexate (MTX) with a total dose of 70 mg followed by cytosine arabinoside (Ara-C) with a total dose of 80 mg for meningeal metastasis of breast carcinoma. Radiation therapy was not given. Despite a response of the meningeal tumor the patient developed in the third week of MTX treatment a progressive visual loss and loss of consciousness which worsened during subsequent Ara-C treatment and led to death within 3 weeks. Postmortem examination revealed only minimal neoplastic infiltration of the meninges. Multiple foci of axonal degeneration and demyelination were found in the optic nerves and chiasm, the superficial layers of the brainstem, and spinal cord and to some extent in other cranial nerves and spinal nerve roots. The possible causes of this previously unreported early complication are discussed.

    Focal basal meningeal enhancement may produce a confusing CT picture in children with suspected tuberculous meningitis (TBM). To demonstrate the incidence, distribution and appearance of localized basal meningeal enhancement in children with TBM. CT scans of patients with definite (culture proven) and probable (CSF suggestive) TBM were retrospectively evaluated by two observers. Localized basal enhancement was documented as involving: unilateral cistern of the lateral fossa (CLF), unilateral sylvian fissure, unilateral CLF and sylvian fissure in combination, unilateral CLF and sylvian fissure with ipsi- or contralateral ambient cistern and isolated quadrigeminal plate cistern. The study included 130 patients with TBM (aged 2 months to 13 years 9 months). Focal basal enhancement was seen in 11 patients (8.5%). The sylvian fissure was involved most commonly, followed by the lateral fossa cistern. The ambient cistern was involved in three patients and the quadrigeminal plate cistern in one. Focal areas of enhancement corresponded to the areas of infarction in every patient. Focal basal meningeal enhancement is common (8.5%) in paediatric TBM. This must be kept in mind when evaluating CT scans in children presenting with focal neurological findings, seizures or meningism in communities where TBM is endemic. (orig.)

  3. Meninges in cancer imaging.

    Mahendru, G; Chong, V

    2009-10-02

    Primary malignant tumours arising from the meninges are distinctly uncommon, and when they occur, they are usually sarcomas. In contrast, metastatic meningeal involvement is increasingly seen as advances in cancer therapy have changed the natural history of malignant disease and prolonged the life span of cancer patients. The meninges can either be infiltrated by contiguous extension of primary tumours of the central nervous system, paranasal sinuses and skull base origin or can be diffusely infiltrated from haematogenous dissemination from distant primary malignancies. Imaging in these patients provides crucial information in planning management. This article reviews the pertinent anatomy that underlies imaging findings, discusses the mechanism of meningeal metastasis and highlights different imaging patterns of meningeal carcinomatosis and the pitfalls.

  4. MRI of primary meningeal sarcomas in two children: differential diagnostic considerations

    Pfluger, T.; Weil, S.; Weis, S.

    1997-01-01

    Meningeal sarcomas are very rare, highly aggressive tumours affecting children more frequently than adults. The clinical course and MRI of meningeal sarcomas in two cases are discussed with special regard to possible misinterpretation. In one case MRI demonstrated a circumscribed mass in contact with the meninges, with central areas of haemorrhage. In the other, a case of primary leptomeningeal sarcomatosis, several MRI examinations over the course of almost a year were unhelpful, despite severe neurological complaints. Then MRI revealed meningeal contrast enhancement all over the brain and spinal canal, together with cerebral infarcts. MRI of meningeal sarcomas has not been discussed in the literature. MRI did not permit specific diagnosis, but enabled visualisation of the extent of the tumour and/or meningeal involvement. Early histological diagnosis is indispensable for adequate treatment.

  5. Laboratorial diagnosis of lymphocytic meningitis

    Sérgio Monteiro de Almeida

    Full Text Available Meningitis is the main infectious central nervous system (CNS syndrome. Viruses or bacteria can cause acute meningitis of infectious etiology. The term "Aseptic Meningitis" denotes a clinical syndrome with a predominance of lymphocytes in the cerebrospinal fluid (CSF, with no common bacterial agents identified in the CSF. Viral meningitis is considered the main cause of lymphocyte meningitis. There are other etiologies of an infectious nature. CSF examination is essential to establish the diagnosis and to identify the etiological agent of lymphocytic meningitis. We examined CSF characteristics and the differential diagnosis of the main types of meningitis.

    1991-01-15

    MR studies were performed in three patients with paralysis in the lower extremities. Poliomyelitis-like paralysis can be caused by neurovirulent strains of nonpolioenteroviruses. Entervirus 71 (EV 71) is documented as one of the potentially neurovirulent strains and a causative agent of some epidemics (1-7). The clinical manifestations associated with the EV 71 infection include aseptic meningitis, hand-food-mouth disease (HFMD), acute respiratory illness and gastrointestinal disease(6). Although rarely fatal, flaccidparalysis can be followed by EV 71 induced aseptic meningitis. Anterior horn cell necrosis was suggested on MR in two patients with residual paralysis (7). MR features, however, have not yet been described in detail. In this report we present three cases of patients with clinical evidence of EV 71 induced aseptic meningitis whose MR studies showed residual changes in spinal cord.

    1983-07-01

    A case of 3-month-old female with ''granulomatous basal meningitis'' caused by pneumococcus was described. She suffered from high fever, vomiting, convulsion and loss of consciousness on January 28th, 1982. On admission the protein content of the spinal fluid was 280 mg/100 ml, the glucose 4 mg/100 ml and the cell count was 1206/3(L : 845, N : 361). Her symptoms and signs were deteriorated in spite of antibiotics and anticonvulsants. CT scan on the 10th day showed the enhanced basal cistern. She died on the 11th day but autopsy was not carried out. In this case, pneumococcus was cultured in CSF. This seemed to be the first case of ''granulomatous basal meningitis'' due to purulent meningitis in Japan.

  13. Communicating hydrocephalus subsequent to purulent meningitis

    Suzuki, Hiroshi; Ogawa, Kimio; Hibio, Shuichi; Goto, Kazuhiko; Shiihara, Hiroaki

    1984-01-01

    Based on CT findings one year after shunting, ventricular dialtion was classified into five degrees for examining prognosis of communicating hydrocephalus subsequent to purulent meningitis. Factors causing and aggravating hydrocephalus were also examined. Patients with hydrocephalus tended to have spasms frequently as the first symptom within one month after birth when there were few characteristic findings. Spasm and disturbance of consciousness occurred frequently during the first week of the occurrence of disease. Large numbers of cells in the spinal fluid and high volume of spinal cord protein were persistent in patients aged one month or less. Chloride transport decreased in patients aged two months or more. The occurrence of syndrome of the pyramidal tract, eye symptoms, movement of head to the left and right, and involuntary movement suggested serious conditions of the disease. Disturbance of movement could be relieved by giving adequate antibiotics as soon as meningitis was discovered within one month after birth and by giving chloramphenicol when symptoms suggesting the development of serious conditions occurred. However, mental retardation and epilepsy could not be prevented. (Namekawa, K.)

    Neurologic complications of bacterial meningitis can occur any time during the course of the disease and some of them need neurosurgical aproach. to determine the incidence of neurologic complications of bacterial meningitis in children requring neurosurgical treatment. a total of 277 children were followed and treated for bacterial meningitis at the Clinic of Infectious Diseases in Prishtina. The authors have analyzed cases who developed acute neurologic complications and treatment procedures. of the 277 children treated for bacterial meningitis, due to the suspicion for neurologic complications, 109 children underwent a head computerized tomography scan. About 47 cases (43%) had evident structural abnormalities while only 15/277 cases (5%) required neurosurgical treatment; 9/38 cases with subdural collections, 5 cases with hydrocephalus and 1 case of spinal abscess. Neurosurgical intervention were not common in pediatric bacterial meningitis cases (5%) but were highly significant in cases complicated with acute neurologic complications (32%).

    Primary meningeal rhabdomyosarcoma is a rare primary brain malignancy, with scant case reports. While most reports of primary intracranial rhabdomyosarcoma occur in pediatric patients, a handful of cases in adult patients have been reported in the medical literature. We report the case of a 44-year-old male who developed primary meningeal rhabdomyosarcoma. After developing episodes of right lower extremity weakness, word finding difficulty, and headaches, a brain magnetic resonance imaging (MRI) demonstrated a vertex lesion with radiographic appearance of a meningeal-derived tumor. Subtotal surgical resection was performed due to sagittal sinus invasion and initial pathology was interpreted as an anaplastic meningioma. Re-review of pathology demonstrated rhabdomyosarcoma negative for alveolar translocation t(2;13). Staging studies revealed no evidence of disseminated disease. He was treated with stereotactic radiotherapy with concurrent temozolamide to be followed by vincristine, actinomycin-D, and cyclophosphamide (VAC) systemic therapy. PMID:21772793

    To demonstrate the epidemiology, clinical manifestations and bacteriological profile of bacterial meningitis in children beyond the neonatal period in our hospital. This was a retrospective descriptive study conducted at Prince Rashid Hospital in Irbid, Jordan. The medical records of 50 children with the diagnosis of bacterial meningitis during 4 years period, were reviewed. The main cause of infection was streptococcus pneumoniae, followed by Haemophilus influenza and Niesseria meningitides. Mortality was higher in infants and meningococcal infection, while complications were more encountered in cases of streptococcus pneumoniae. Cerebrospinal fluid culture was positive in 11 cases and Latex agglutination test in 39. There is a significant reduction of the numbers of bacterial meningitis caused by Haemophilus influenza type B species. (author)

  2. High Yield of Adult Oligodendrocyte Lineage Cells Obtained from Meningeal Biopsy

    Sissi Dolci

    2017-10-01

    Full Text Available Oligodendrocyte loss can lead to cognitive and motor deficits. Current remyelinating therapeutic strategies imply either modulation of endogenous oligodendrocyte precursors or transplantation of in vitro expanded oligodendrocytes. Cell therapy, however, still lacks identification of an adequate source of oligodendrocyte present in adulthood and able to efficiently produce transplantable cells. Recently, a neural stem cell-like population has been identified in meninges. We developed a protocol to obtain high yield of oligodendrocyte lineage cells from one single biopsy of adult rat meningeal tissue. From 1 cm2 of adult rat spinal cord meninges, we efficiently expanded a homogenous culture of 10 millions of meningeal-derived oligodendrocyte lineage cells in a short period of time (approximately 4 weeks. Meningeal-derived oligodendrocyte lineage cells show typical mature oligodendrocyte morphology and express specific oligodendrocyte markers, such as galactosylceramidase and myelin basic protein. Moreover, when transplanted in a chemically demyelinated spinal cord model, meningeal-derived oligodendrocyte lineage cells display in vivo-remyelinating potential. This oligodendrocyte lineage cell population derives from an accessible and adult source, being therefore a promising candidate for autologous cell therapy of demyelinating diseases. In addition, the described method to differentiate meningeal-derived neural stem cells into oligodendrocyte lineage cells may represent a valid in vitro model to dissect oligodendrocyte differentiation and to screen for drugs capable to promote oligodendrocyte regeneration.

  5. Spinal infection: Evaluation with MR imaging and intraoperative spinal US

    Donovan Post, M.J.; Montalvo, B.M.; Quencer, R.M.; Katz, B.H.; Green, B.A.; Elsmont, F.

    1987-01-01

    MR spine images and/or intraoperative US scans in 15 patients were reviewed retrospectively and correlated with clinical and pathologic data to determine the diagnostic value of these modalities in spinal infection. In osteomyelitis and retrospinal abscess MR imaging was definitive; in myelitis it was positive but nonspecific. In epidural abscess concomitant with meningitis, myelography with CT and intraoperative US were superior to MR imaging. Intraoperative US could be used to distinguish these processes and to monitor surgical decompression. The authors recommend that MR imaging be performed at the screening examination in cases of spinal infection, accompanied by intraoperative US in all surgical cases

    Full Text Available Meningeal fibrosarcomas are rare tumors. Only 41 cases have been reported in the literature to date. Primary central nervous system fibrosarcomas are very aggressive neoplasms and have a poor prognosis. Hence they need to be correctly diagnosed. This is a case of a 13-year old boy with intracranial space occupying lesion. The mass was completely removed and histological examination was characteristic of meningeal fibrosarcoma. The pathological diagnosis is usually made on routine light microscopic examination; however, occasionally these may be difficult to distinguish from other malignant neoplasms such as gliomas, meningiomas and metastases. The diagnosis of fibrosarcoma is based on the identification of a predominant herringbone architectural pattern, the overall uniformity of the spindle cell population, the prominent vimentin positivity, and the presence of pericellular reticulin fibre network. IHC helps to exclude other diagnoses.

  9. Management of neoplastic meningitis.

    Roth, Patrick; Weller, Michael

    2015-06-01

    Leptomeningeal dissemination of tumor cells, also referred to as neoplastic meningitis, is most frequently seen in patients with late-stage cancer and mostly associated with a poor prognosis. Basically, neoplastic meningitis may affect all patients with a malignant tumor but is most common in patients affected by lung cancer, breast carcinoma, melanoma or hematologic neoplasms such as lymphoma and leukemia. Controlled clinical trials are largely lacking which results in various non-standardized treatment regimens. The presence of solid tumor manifestations in the CNS as well as the extracranial tumor load defines the most appropriate treatment approach. Radiation therapy, systemic chemotherapy and intrathecal treatment must be considered. For each patient, the individual situation needs to be carefully evaluated to determine the potential benefit as well as putative side effects associated with any therapy. A moderate survival benefit and particularly relief from pain and neurological deficits are the main treatment goals. Here, we summarize the management of patients with neoplastic meningitis and review the available treatment options.

    Lu, M Y; Lee, P I; Lee, C Y; Hsu, C J

    1996-01-01

    Mondini dysplasia is a congenital malformation of the inner ear, commonly associated with hearing impairment, cerebrospinal fluid otorrhea/rhinorrhea and recurrent meningitis. Two such cases are described, with hearing impairment, cerebrospinal fluid rhinorrhea, and several episodes of meningitis. Diagnosis was confirmed by high-resolution computed tomography. After surgical correction of the malformation, there was no recurrent episode of meningitis at subsequent follow-up. To avoid the suffering and the sequelae of recurrent meningitis, an early diagnosis and prompt surgical intervention are crucial for such patients.

  11. The incidence and risk factors of meningitis after major craniotomy in China: a retrospective cohort study.

    Chen Chen

    Full Text Available BACKGROUND: Meningitis after neurosurgery can result in severe morbidity and high mortality. Incidence varies among regions and limited data are focused on meningitis after major craniotomy. AIM: This retrospective cohort study aimed to determine the incidence, risk factors and microbiological spectrum of postcraniotomy meningitis in a large clinical center of Neurosurgery in China. METHODS: Patients who underwent neurosurgeries at the Department of Neurosurgery in Huashan Hospital, the largest neurosurgery center in Asia and the Pacific, between 1st January and 31st December, 2008 were selected. Individuals with only shunts, burr holes, stereotactic surgery, transsphenoidal or spinal surgery were excluded. The complete medical records of each case were reviewed, and data on risk factors were extracted and evaluated for meningitis. RESULTS: A total of 65 meningitides were identified among 755 cases in the study, with an incidence of 8.60%. The risk of meningitis was increased by the presence of diabetes mellitus (odds ratio [OR], 6.27; P = 0.009, the use of external ventricular drainage (OR, 4.30; P = 0.003 and the use of lumbar drainage (OR, 17.23; P<0.001. The isolated microorganisms included Acinetobacter baumannii, Enterococcus sp, Streptococcus intermedius and Klebsiella pneumonia. CONCLUSIONS: Meningitis remains an important source of morbidity and mortality after major craniotomy. Diabetic patients or those with cerebral spinal fluid shunts carry significant high risk of infection. Thus, identification of the risk factors as soon as possible will help physicians to improve patient care.

    The objective of this study was to investigate the antioxidant/oxidant status of serum and cerebrospinal fluid in children with meningismus and acute bacterial meningitis. Twenty-three children (age range, 0.75 to 9 years) with fever and meningeal signs that required analysis of the cerebrospinal fluid, but no cytologic or biochemical evidence of meningitis in their serum and cerebrospinal fluid, constituted the meningismus group. Thirty-one children (age range, 0.5 to 10 years) with acute bacterial meningitis constituted the meningitis group. Twenty-nine healthy children (age range, 0.5 to 11 years) were recruited as control subjects. Antioxidant status (ascorbic acid, albumin, thiol, uric acid, total bilirubin, total antioxidant capacity, catalase and ceruloplasmin concentrations) and oxidant status (lipid hydroperoxide and total oxidant status) were measured. The serum antioxidant status was lower, and oxidant status levels higher in both meningitis and meningismus subjects than in the control children (P antioxidant status was lower, and serum oxidant status was higher in children in the meningismus and meningitis groups, whereas cerebrospinal fluid oxidant status was higher in the meningismus group than in the meningitis group.

  13. MR myelography of sacral meningeal cysts

    Tsuchiya, K.; Katase, S.; Hachiya, J.

    1999-01-01

    Purpose: To describe the findings of sacral meningeal cysts (SMCs) on MR myelography and assess its value for the diagnosis of SMCs. Material and Methods: We evaluated the MR images and MR myelograms obtained from 10 patients with SMC. MR myelograms were obtained using a 2D or 3D single-shot fast spin-echo sequence. In 5 patients, X-ray myelograms and postmyelographic CT images were compared with the MR myelograms. Results: A total of 33 SMCs were diagnosed within the spinal canal and/or sacral foramen. MR myelograms clearly revealed each cyst as a well-defined mass showing hyperintensity (10 cysts) or isointensity (23 cysts) compared to cerebrospinal fluid. MR myelograms demonstrated SMCs better than X-ray myelograms and postmyelographic CT images in 3 of the 5 patients. Conclusion: MR myelography can be an adjunct to conventional imaging techniques when surgical treatment is indicated, because it can precisely delineate the extent of SMCs. (orig.)

    Two women in labor received intrapartum spinal anesthesia from the same anesthesiologist approximately 1 h apart. Within 15 h, both patients developed Streptococcus salivarius meningitis and one patient died. Blood and cerebrospinal fluid (CSF) samples from both patients and tongue swab specimens from the anesthesiologist yielded isolates of an indistinguishable S. salivarius strain. PMID:20504987

    Acquired recto-spinal fistula has been described elsewhere as a rare complication of colorectal malignancy and Crohn's enterocolitis. We treated a young man who developed a recto-spinal fistula as a result of a high fall injury. The patient presented with meningeal signs, sepsis and perianal laceration. Computerized axial tomography revealed air in the supersellar cistern. Gastrografin enema showed that contrast material was leaking from the rectum into the spinal canal. Surgical management included a diverting sigmoid colostomy, sacral bone curettage and wide presacral drainage. To the best of our knowledge, rectospinal fistula of traumatic origin has not been previously reported in the English literature. (orig.)

  17. Spinal cord injury arising in anaesthesia practice.

    Hewson, D W; Bedforth, N M; Hardman, J G

    2018-01-01

    Spinal cord injury arising during anaesthetic practice is a rare event, but one that carries a significant burden in terms of morbidity and mortality. In this article, we will review the pathophysiology of spinal cord injury. We will then discuss injuries relating to patient position, spinal cord hypoperfusion and neuraxial techniques. The most serious causes of spinal cord injury - vertebral canal haematoma, spinal epidural abscess, meningitis and adhesive arachnoiditis - will be discussed in turn. For each condition, we draw attention to practical, evidence-based measures clinicians can undertake to reduce their incidence, or mitigate their severity. Finally, we will discuss transient neurological symptoms. Some cases of spinal cord injury during anaesthesia can be ascribed to anaesthesia itself, arising as a direct consequence of its conduct. The injury to a spinal nerve root by inaccurate and/or incautious needling during spinal anaesthesia is an obvious example. But in many cases, spinal cord injury during anaesthesia is not caused by, related to, or even associated with, the conduct of the anaesthetic. Surgical factors, whether direct (e.g. spinal nerve root damage due to incorrect pedicle screw placement) or indirect (e.g. cord ischaemia following aortic surgery) are responsible for a significant proportion of spinal cord injuries that occur concurrently with the delivery of regional or general anaesthesia. © 2018 The Association of Anaesthetists of Great Britain and Ireland.

  18. Spontaneous pneumorrhachis and transverse myelitis complicating purulent meningitis

    Bouchra Amara

    2013-01-01

    Full Text Available Pneumorrhachis is the presence of air in the spinal canal; mostly, it has an iatrogenic origin. The association of this entity with spontaneous pneumomediastinum without any pneumothorax is rarely reported in the literature. The spontaneous resorption is the usual evolution. The association to acute transverse myelitis is discussed by the authors. The patient is a 21-year-old male with pneumorrhachis associated to a spontaneous pneumomediastinum was admitted at the emergency department for bacterial meningitis. The antibiotherapy has marked the clinical profile by disappearance of the meningeal signs in the 48 h after admission. In contrast, the neurological symptoms were of marked aggravation by appearance of a tetraparesis with a respiratory distress syndrome having required artificial ventilation. The computed tomography (CT scan showed a typical hypodensity corresponding to paramedullary air extending to several thoracic segments. The spinal magnetic resonance imaging (MRI showed a high cervical medullary edema without signs of compression. The patient died within 15 days with a profile of vasoparalysis resistant to vasoactive drugs. Pneumomediastinum associated to pneumorrhachis and transverse myelitis complicating purulent meningitis is a rare entity. Although the usual evolution is favorable, the occurrence of serious complications is possible.

  19. Pituitary apoplexy masquerading as meningitis

    meningeal irritation is not considered a classic feature of pituitary apoplexy.2,3 The pathophysiology behind this symptom complex involves leakage of blood into the subarachnoid space, which, in conjunction with the necrotic tissue in the pituitary itself, induces a cytokine response, resulting in meningeal irritation and the.

  2. Persistent Neutrophilic Meningitis in an Immunocompetent Patient after Basilar Skull Fracture: Case Report

    Uslan Daniel Z

    2011-05-01

    Full Text Available Abstract Background Persistent neutrophilic meningitis is an unusual form of chronic meningitis that is defined as clinical meningitis with a neutrophilic pleocytosis that persists for greater than 7 days despite empiric antimicrobial therapy. Although numerous disease processes can cause this syndrome, the majority of cases are due to opportunistic pathogens infecting immunocompromised hosts. Case Presentation A 47 year-old female presented after basilar skull fracture with persistent neutrophilic meningitis unresponsive to empiric broad-spectrum antibiotics. After more than weeks of intensive therapy, 4 hospitalizations and 3 relapses, Nocardia cyriacigeorgica was identified from cerebral spinal fluid. Induction therapy was begun with Ceftriaxone and trimethoprim-sulfamethoxazole (TMP-SMX for 6 weeks followed by therapy with TMP-SMX and doxycycline for one year. The patient made a complete recovery without sequelae. Conclusions Due to the difficulty in obtaining a microbiologic diagnosis, appropriate treatment in cases of persistent neutrophilic meningitis is often delayed leading to morbidity, This case highlights a number of the unique features of Nocardia meningitis and the importance of considering Nocardia infection as a cause of persistent neutrophilic meningitis even in immunocompetent patients.

  3. The Meningitis Vaccine Project.

    LaForce, F Marc; Konde, Kader; Viviani, Simonetta; Préziosi, Marie-Pierre

    2007-09-03

    Epidemic meningococcal meningitis is an important public health problem in sub-Saharan Africa. Current control measures rely on reactive immunizations with polysaccharide (PS) vaccines that do not induce herd immunity and are of limited effectiveness in those under 2 years of age. Conversely, polysaccharide conjugate vaccines are effective in infants and have consistently shown an important effect on decreasing carriage, two characteristics that facilitate disease control. In 2001 the Meningitis Vaccine Project (MVP) was created as a partnership between PATH and the World Health Organization (WHO) with the goal of eliminating meningococcal epidemics in Africa through the development, licensure, introduction, and widespread use of conjugate meningococcal vaccines. Since group A Neisseria meningitidis (N. meningitidis) is the dominant pathogen causing epidemic meningitis in Africa MVP is developing an affordable (US$ 0.40 per dose) meningococcal A (Men A) conjugate vaccine through an innovative international partnership that saw transfer of a conjugation and fermentation technology to a developing country vaccine manufacturer. A Phase 1 study of the vaccine in India has shown that the product is safe and immunogenic. Phase 2 studies have begun in Africa, and a large demonstration study of the conjugate vaccine is envisioned for 2008-2009. After extensive consultations with African public health officials a vaccine introduction plan has been developed that includes introduction of the Men A conjugate vaccine into standard Expanded Programme on Immunization (EPI) schedules but also emphasizes mass vaccination of 1-29 years old to induce herd immunity, a strategy that has been shown to be highly effective when the meningococcal C (Men C) conjugate vaccine was introduced in several European countries. The MVP model is a clear example of the usefulness of a "push mechanism" to finance the development of a needed vaccine for the developing world.

    2018-02-15

    Spinal cysts can be classified as meningeal, not meningeal, and tumor-associated cysts. Due to the widespread availability of high-resolution computed tomography and magnet resonance imaging, spinal cysts can be detected with high sensitivity these days. Concerning the variety of potential cystic differential diagnoses, a precise classification is difficult and can often only be realized after surgical inspection or histological examination. Spinal cysts are generally incidental findings during a routine diagnostic workup and need no further therapy. Surgical treatment can be necessary if the spinal cyst reaches a certain size and causes neurological symptoms due to the compression of the spinal cord or the nerve root. (orig.) [German] Spinale Zysten koennen in meningeale, nichtmeningeale und tumorassoziierte Zysten eingeteilt werden. Durch die weite Verbreitung von hochaufloesenden Computer- und Magnetresonanztomographen koennen spinale Zysten heutzutage mit einer hohen Sensitivitaet erkannt werden. Eine genaue Klassifikation kann sich unter der Vielzahl der moeglichen zystischen Differenzialdiagnosen schwierig gestalten und ist haeufig nur durch eine chirurgische Inspektion oder die histologische Untersuchung moeglich. Meistens werden spinale Zysten bei der Routinediagnostik als Zufallsbefunde entdeckt und benoetigen keine weitere Therapie. Erreichen sie allerdings eine gewisse Groesse, koennen sie raumfordernd auf das Myelon oder einzelne Nervenwurzeln wirken und somit ausgepraegte neurologische Symptome verursachen. In solchen Faellen ist ein chirurgisches Vorgehen zur Resektion einer spinalen Zyste notwendig. (orig.)

    2016-01-01

    Abstract The zoonotic pathogen Campylobacter fetus is a rare cause of bacterial meningitis. Little is known about the clinical characteristics, predisposing factors and outcome of C fetus meningitis in adults. We report cases of C fetus meningitis in a nationwide cohort study of adult bacterial meningitis patients in the Netherlands and performed a review of the literature. Two patients with C fetus meningitis were identified from January 2006 through May 2015. The calculated annual incidence was 0.02 per million adults. Combined with the literature, we identified 22 patients with a median age of 48 years. An immunocompromised state was present in 16 patients (73%), mostly due to alcoholism (41%) and diabetes mellitus (27%). The source of infection was identified in 13 out of 19 patients (68%), consisting of regular contact with domestic animals in 5 and working on a farm in 4. Recurrent fever and illness was reported in 4 patients (18%), requiring prolonged antibiotic treatment. Two patients died (9%) and 3 survivors (15%) had neurological sequelae. C fetus is a rare cause of bacterial meningitis and is associated with an immunocompromised state. Based on the apparent slow clinical response seen in this limited number of cases, the authors of this study recommend a prolonged course of antimicrobial therapy when C fetus is identified as a causative agent of bacterial meningitis. Cases appeared to do best with carbapenem therapy. PMID:26937916

    Watanabe, M.; Tanaka, R.; Takeda, N.

    1993-01-01

    Ten patients with meningeal carcinomatosis associated with nonhaemoatological neoplasms were examined: Six with breast, two with gastrointestinal and one with lung cancer, plus one with a tumour of unknown origin. Cytology was positive in all but one. The patients were classified into four groups according to the gadolinium-enhanced MRI (Gd-MRI) appearances: Group 1 had pure leptomeningeal carcinomatosis, group 2 dural carcinomatosis, group 3 spinal leptomeningeal carcinomatosis, and group 4 had normal Gd-MRI except for hydrocephalus. In group 1, Gd-MRI showed diffuse enhancement of the subarachnoid space, including the cisterns around the midbrain, the sylvian fissures, or cerebellar and cerebral sulci. In group 2, Gd-MRI showed diffuse, thick, partially nodular enhancement of the dura mater. No leptomeningeal or subependymal enhancement was evident. In group 3, nodular masses were seen only in the spinal canal. In group 4, no definite evidence of meningeal carcinomatosis was demonstrated on contrast-enhanced CT (CE-CT) or Gd-MRI. The median survival time was 2.0 months in group 1, 1.0 month in group 3, and 4.5 months in group 4, but the two patients in group 2 were alive 10 and 15 months after a definite diagnosis of meningeal carcinomatosis was made. In all patients examined by both CE-CT and Gd-MRI, the latter was superior for identification of meningeal carcinomatosis. Hydrocephalus is an important indirect sign of leptomeningeal carcinomatosis, but was not seen in patients with dural carcinomatosis despite the presence of increased intracranial pressure. (orig.)

    Meningitis after neurosurgery can result in severe morbidity and high mortality. Incidence varies among regions and limited data are focused on meningitis after major craniotomy. This retrospective cohort study aimed to determine the incidence, risk factors and microbiological spectrum of postcraniotomy meningitis in a large clinical center of Neurosurgery in China. Patients who underwent neurosurgeries at the Department of Neurosurgery in Huashan Hospital, the largest neurosurgery center in Asia and the Pacific, between 1st January and 31st December, 2008 were selected. Individuals with only shunts, burr holes, stereotactic surgery, transsphenoidal or spinal surgery were excluded. The complete medical records of each case were reviewed, and data on risk factors were extracted and evaluated for meningitis. A total of 65 meningitides were identified among 755 cases in the study, with an incidence of 8.60%. The risk of meningitis was increased by the presence of diabetes mellitus (odds ratio [OR], 6.27; P = 0.009), the use of external ventricular drainage (OR, 4.30; P = 0.003) and the use of lumbar drainage (OR, 17.23; PMeningitis remains an important source of morbidity and mortality after major craniotomy. Diabetic patients or those with cerebral spinal fluid shunts carry significant high risk of infection. Thus, identification of the risk factors as soon as possible will help physicians to improve patient care.

    Establishing characteristic epidemiologic and microbiologic features of acute meningitis in the Córdoba department. A descriptive epidemiological study was carried out between June 2002 and June 2004 at the Hospital San Jerónimo in Montería. All suspicious cases of meningitis were included; laboratory tests included cytological smear, biochemistry, latex, Gram stain and culture. 57 (11.3%) and 85 (16.8%) of the 503 samples of cerebrum spinal fluid (CSF) were confirmed by culture as being probable cases. There were 6 cases of polymicrobial infection, making a total of 63 isolates: 17 non-fermenting Gram-negative bacilli (26.9%), 16 Streptococcus pneumoniae (25.4%), 7 Enterobacteriaceae (11%), 5 Criptococcus neoformans (8%) 4 Neisseria meningitidis serotype B (6.3%), 3 S. viridans (4.8%), 2 Streptococcus group B (3.2%), 2 Haemophilus influenzae type B (3.2%), 2 Staphylococcus negative coagulase (3.2%), 2 S. aureus (3.2%), 2 Enterococcus (3.2%) and 1 Candida albicans (1.6%). The S. Pneumoniae serotypes found were: 5 (n=4), 23F (n=3), 14 (n=2), 18C (n=2), 18A (n=l1, 17F (n=l1, 1 (n=1). The study led to determining epidemiological and microbiological aspects of acute meningitis in the Códoba department which had been unknown up to now. Streptococcus pneumoniae (25.4% was the main aetiological agent of meningitis; the epidemiologic aspects so established confirmed the need for strengthening and implementing measures for controlling meningitis in C6ódoba and its surveillance there.

    Twenty nine infants with meningitis purulenta were classified into 5 groups according to CT findings in the acute stage: cerebral infarction group, subdural hygroma group, ventricular enlargement group, and a group of other diseases. In each group, clinical findings, surgical procedures and prognosis were evaluated. In the cerebral infarction group, although 3 of 4 patients underwent V-P shunt or subdural drainage, remarkable sequelae were found in all the cases. Of 4 subdural hygroma patients, 2 had subdural drainage, and 4 of 8 patients with ventricular enlargement underwent V-P shunt. All the patients of the two groups had favorable prognosis without any sequela. A patient with cerebral herniation in the group of other diseases died in its acute stage. Eleven infants without abnormal CT findings showed normal psychomotor development. (Ueda, J.)

  12. Lumbar meningeal enhancement after surgery in the posterior cranial fossa: a normal finding in children?

    Krampla, W.; Urban, M.; Newrkla, S.; Hruby, W.; Schatzer, R.; Knosp, E.

    2002-01-01

    Purpose: Spinal meningeal Gd-DTPA enhancement after cranial surgery is a known observation of a not well understood underlying mechanism. This paper demonstrates that this MRI finding is a normal meningeal reaction to subarachnoid hemorrhage, which should not be mistaken for metastatic spread. Material and methods: Three pediatric patients were examined by MRI for metastatic spread of malignant infratentorial tumors along the spinal canal two to nine days after the removal of the primary cerebral lesion. The findings were compared with a control group that underwent cranial surgery (cyst resection or fenestration of the posterior cranial fossa) without major bleeding into the subarachnoid space. Unenhanced and enhanced sequences were obtained to prove that the high singal within the CSF is caused by an abnormal Gd-DTPA uptake and not by methemoglobin. Results: Meningeal enhancement was observed in all patients with intraoperative bleeding resembling subarachnoid masses on enhanced T 1 -weighted images. This was not present in any patient of the control group. This finding lasts for approximately two weeks. Conclusion: The meningeal enhancement renders immediate postoperative studies inconclusive for the detection of metastatic spread. Consequently, the obligatory tumor staging along the spinal canal should ideally be done prior to the resection of a cerebral tumor. (orig.) [de

    2006-01-01

    The safety of ketamine when administered by the spinal route must be confirmed in various animal species before it is approved for use in humans. This study evaluates the ultrastructure of canine meninges after repeated doses of epidural S(+)-ketamine. Five dogs received S(+)-ketamine 5%, 1 mg/kg, twice a day for 10 days through an epidural catheter with its tip located at the L5 level. One dog received the same volume of normal saline at the same times. The spinal cord and meninges were processed for histopathological and ultrastructural studies. Clinical effects were assessed after each injection. Motor and sensory block appeared after each injection of S(+)-ketamine, but not in the dog receiving saline. No signs of clinical or neurologic alterations were observed. Using light microscopy, no meningeal layer showed alterations except focal infiltration at the catheter tip level by macrophages, lymphocytes, and a few mast cells. The cells of different layers were studied by electron microscopy and interpreted according to data from human and other animal species because no ultrastructural description of the canine meninges is currently available. There were no cellular signs of inflammation, phagocytosis, or degeneration in meningeal layers and no signs of atrophy, compression, or demyelinization in the areas of dorsal root ganglia and spinal cord around the arachnoid. These findings were common for dogs receiving S(+)-ketamine and the dog receiving saline. Repeated doses of epidural S(+)-ketamine 5%, 1 mg/kg, twice a day for 10 days was not associated to cellular alterations in canine meninges.

    Angela McCormick

    2012-12-01

    Full Text Available A 58-year-old male patient presented to the emergency department with complaints of severe neck pain. He admitted to drug use but denied using intravenous (IV drugs. On exam, he had a fever of 100.7 F, positive Kernig’s sign, and normal neurologic exam. The patient was suspected to have bacterial meningitis and was started on IV antibiotics. The next day the patient developed decreased hand grip. Magnetic resonance imaging of the spine the next day showed a soft-tissue mass impinging on the spinal canal. The patient was subsequently taken to the operating room where the epidural abscess was drained.

    Recently, tuberculous meningitis has become rather rare except in areas where tuberculosis is still endemic. Six adolescents and young adults with tuberculous meningitis were evaluated by means of serial computerized tomography (CT), and the results were correlated with the findings of surgical specimens or autopsies. All cases showed meningeal irritation and fever at onset. CSF cultures revealed the presence of tuberculous bacilli. Four cases advanced rapidly to the clinical stage III and expired in a short period-between two weeks to one month from onset. On initial CT scanning, the disappearance of the basal cistern was a characteristic finding in all these cases. With the progression, an enhancement of the basal cistern on contrast injection, a localized hypodensity in adjacent parenchyma, and symmetrical ventricular dilatation appeared. Two autopsied cases showed tuberculous granulomas with purulent materials, thickened meninges, and caseous necrosis in the parenchyma around the basal cistern. The other two cases progressed rather slowly. CT findings at Stage II showed multiple enhanced spots in the basal subcortical area following contrast injection. Tuberculous granulomas were identified in these parts by means of explorative craniotomy. The authors point out the pathognomonic CT findings of tuberculous meningitis and emphasize the necessity of serial CT for the early detection and management of tuberculous meningitis. (author)

    To evaluate the potential role of CSF lactate level in the diagnosis of acute bacterial meningitis and in the differentiation between viral and bacterial meningitis. This was a hospital based observational study, conducted at Infectious Diseases Unit, Rashid Hospital Dubai, United Arab Emirates, from July 2004 to June 2007. The patients with clinical diagnosis of acute bacterial meningitis and who had CSF Gram stain/culture positive, CSF analysis suggestive of bacterial meningitis with negative Gram stain and culture but blood culture positive for bacteria and patients with clinical diagnosis suggestive of viral meningitis supported by CSF chemical analysis with negative Gram stain and culture as well as negative blood culture for bacteria were included in the study. CT scan brain was done for all patients before lumber puncture and CSF and blood samples were collected immediately after admission. CSF chemical analysis including lactate level was done on first spinal tap. The CSF lactate level was tested by Enzymatic Colorimetric method. A total 95 adult patients of acute meningitis (53 bacterial and 42 viral) fulfilled the inclusion criteria. Among 53 bacterial meningitis patients, Neisseria meningitides were isolated in 29 (54.7%), Strept. Pneumoniae in 18 (33.96%), Staph. Aureus in 2 (3.77%), Klebsiell Pneumoniae in 2 (3.77%), Strept. Agalactiae in 1 (1.8%) and E. Coli in 1 (1.8%). All the patients with bacterial meningitis had CSF lactate > 3.8 mmol/l except one, whereas none of the patients with viral meningitis had lactate level > 3.8 mmol/l. The mean CSF lactate level in bacterial meningitis cases amounted to 16.51 +/- 6.14 mmol/l, whereas it was significantly lower in viral group 2.36 +/- 0.6 mmol/l, p < .0001. CSF lactate level was significantly high in bacterial than viral meningitis and it can provide pertinent, rapid and reliable diagnostic information. Furthermore, CSF lactate level can also differentiate bacterial meningitis from viral one in a quick

    2015-04-01

    Full Text Available Objective : To verify the relationship between intracranial pressure and flash visual evoked potentials (F-VEP in patients with cryptococcal meningitis. Method The sample included adults diagnosed with cryptococcal meningitis admitted at a reference hospital for infectious diseases. The patients were subjected to F-VEP tests shortly before lumbar puncture. The Pearson’s linear correlation coefficient was calculated and the linear regression analysis was performed. Results : Eighteen individuals were subjected to a total of 69 lumbar punctures preceded by F-VEP tests. At the first lumbar puncture performed in each patient, N2 latency exhibited a strong positive correlation with intracranial pressure (r = 0.83; CI = 0.60 - 0.94; p < 0.0001. The direction of this relationship was maintained in subsequent punctures. Conclusion : The intracranial pressure measured by spinal tap manometry showed strong positive association with the N2 latency F-VEP in patients with cryptococcal meningitis.

  5. CT scan of bacterial and aseptic meningitis

    Takemoto, Kazumasa; Saiwai, Shigeo; Tamaoka, Koichi

    1983-01-01

    CT scans of the patients with aseptic and bacterial meningitis were reviewed and compared to previous reports. In aseptic meningitis, no abnormal CT findings were observed. In bacterial meningitis, CT findings were ventricular dilatation, subdural fluid collection, parenchymal low density, intracerebral hematoma and meningeal enhancement after contrast injection. Three patients among 48 suffered from status epileptics during the course of the illness. All of 3 patients developed parenchymal inhomogeneous low density and progressive ventricular dilatation which did not improve after ventricular peritoneal shunt surgery. We believe that these changes are most likely due to hypoxic hypoxemia during epileptic seizure and meningitis itself seems to play a little role. (author)

  6. Meningeal mast cell-T cell crosstalk regulates T cell encephalitogenicity.

    Russi, Abigail E; Walker-Caulfield, Margaret E; Guo, Yong; Lucchinetti, Claudia F; Brown, Melissa A

    2016-09-01

    GM-CSF is a cytokine produced by T helper (Th) cells that plays an essential role in orchestrating neuroinflammation in experimental autoimmune encephalomyelitis, a rodent model of multiple sclerosis. Yet where and how Th cells acquire GM-CSF expression is unknown. In this study we identify mast cells in the meninges, tripartite tissues surrounding the brain and spinal cord, as important contributors to antigen-specific Th cell accumulation and GM-CSF expression. In the absence of mast cells, Th cells do not accumulate in the meninges nor produce GM-CSF. Mast cell-T cell co-culture experiments and selective mast cell reconstitution of the meninges of mast cell-deficient mice reveal that resident meningeal mast cells are an early source of caspase-1-dependent IL-1β that licenses Th cells to produce GM-CSF and become encephalitogenic. We also provide evidence of mast cell-T cell co-localization in the meninges and CNS of recently diagnosed acute MS patients indicating similar interactions may occur in human demyelinating disease.

  8. Cochlear implant after bacterial meningitis.

    Bille, Jesper; Ovesen, Therese

    2014-06-01

    The aim of this retrospective case study at a tertiary referral center was to investigate the outcome of cochlear implantation (CI) in children with sensorineural hearing loss due to meningitis compared to CI in children with deafness due to other reasons. This post-meningial group (PMG) consisted of 22 children undergoing CI due to deafness induced by meningitis, between December 1996 and January 2012. Five children had bilateral simultaneous implantation. None was excluded and the children were followed for at least 3 years. Operations were carried out by one of two surgeons using similar techniques in all cases. Each patient from the PMG was matched 2:1 with children having implantation for other reasons according to age and follow up (control group). Overall, the median category of auditory performance (CAP) and speech intelligibility rating (SIR) score were not statistically significantly different between the two groups. The presence of additional central nervous system (CNS) disorders (post-meningeal sequelae), however, correlated significantly with poorer outcome CI was a safe procedure without surgical complications in the present study. It is possible to restore auditory capacity and speech performance to a degree comparable to children undergoing implantation for other reasons. A statistically important variable is secondary CNS involvement. The rehabilitation program after CI should be adjusted according to these additional handicaps. It is recommended to screen meningitis patients as fast as possible to identify those with hearing loss and initiate treatment with hearing aids or CI. © 2013 The Authors.

    Koizumi, H; Ono, N; Horikoshi, S; Uki, J; Takeda, F [Saitama Cancer Center (Japan)

    1982-04-01

    CT findings of meningeal carcinomatosis were studied in 17 patients (seven with lung cancer, two with breast cancer, one with gastric cancer, one with malignant melanoma, five with leukemia, and one with malignant lymphoma). The diagnosis was confirmed by a cytological survey of the cerebrospinal fluid and/or autopsy. Signs and symptoms caused by meningeal carcinomatosis at the CT examination varied from individual to individual. Those most frequently observed were signs of increased intracranial pressure, often accompanied by cranial nerve palsies, paresthesia, motor weakness, cerebellar signs, and nuchal stiffness, CT scan revealed evidence of meningeal carcinomatosis in ten cases out of the seventeen. CT evidences were obtained in 16.7% of the cases with hematologic malignancy and in 81.8% of those with non-hematologic malignancies. The CT findings of meningeal carcinomatosis may be summarized as follows: I. 1) Obliteration and narrowing of the cisterns and sulci, with contrast enhancement along them. 2) Enhanced spots/areas beneath the brain surface, with contrast enhancement. 3) Diffuse, slightly high density of the brain surface, with contrast enhancement. 4) Enhancement of the ventricular wall. 5) Hydrocephalus.

  11. Mast cell activation and neutrophil recruitment promotes early and robust inflammation in the meninges in EAE.

    Christy, Alison L; Walker, Margaret E; Hessner, Martin J; Brown, Melissa A

    2013-05-01

    The meninges are often considered inert tissues that house the CSF and provide protection for the brain and spinal cord. Yet emerging data demonstrates that they are also active sites of immune responses. Furthermore, the blood-CSF barrier surrounding meningeal blood vessels, together with the blood-brain barrier (BBB), is postulated to serve as a gateway for the pathological infiltration of immune cells into the CNS in multiple sclerosis (MS). Our previous studies using mast cell-deficient (Kit(W/Wv)) mice demonstrated that mast cells resident in the dura mater and pia mater exacerbate experimental autoimmune encephalomyelitis (EAE), a rodent model of MS, by facilitating CNS inflammatory cell influx. Here we examined the underlying mechanisms that mediate these effects. We demonstrate that there are dramatic alterations in immune associated gene expression in the meninges in pre-clinical disease, including those associated with mast cell and neutrophil function. Meningeal mast cells are activated within 24 h of disease induction, but do not directly compromise CNS vascular integrity. Rather, through production of TNF, mast cells elicit an early influx of neutrophils, cells known to alter vascular permeability, into the meninges. These data add to the growing evidence that inflammation in the meninges precedes CNS immune cell infiltration and establish that mast cells are among the earliest participants in these disease-initiating events. We hypothesize that mast cell-dependent neutrophil recruitment and activation in the meninges promotes early breakdown of the local BBB and CSF-blood barrier allowing initial immune cell access to the CNS.

  12. Pigmented Epithelioid Melanocytoma (PEM)/Animal Type Melanoma (ATM): Quest for an Origin. Report of One Unusual Case Indicating Follicular Origin and Another Arising in an Intradermal Nevus.

    Tarasen, Ashley; Carlson, J Andrew; Leonard, M Kathryn; Merlino, Glenn; Kaetzel, David; Slominski, Andrzej T

    2017-08-15

    Pigmented epithelioid melanocytoma (PEM) is a tumor encompassing epithelioid blue nevus of Carney complex (EBN of CNC) and was previously termed animal-type melanoma. Histologically PEMs are heavily pigmented spindled and epithelioid dermal melanocytic tumors with infiltrative borders, however, their origin remains unclear. Stem cells for the epidermis and hair follicle are located in the bulge area of the hair follicle with the potential to differentiate into multiple lineages. Multiple cutaneous carcinomas, including follicular cutaneous squamous cell carcinoma (FSCC), are thought to arise from stem cells in the follicular bulge. We present two cases of PEM/ATM in a 63 year-old male on the scalp with follicular origin and a 72 year-old female on the upper back arising in an intradermal nevus. Biopsy of both cases revealed a proliferation of heavily pigmented dermal nests of melanocytes with atypia. The Case 1 tumor was in continuation with the outer root sheath of the hair follicle in the bulge region. Case 2 arose in an intradermal melanocytic nevus. Rare mitotic figures, including atypical mitotic figures, were identified in both cases. We present two cases of PEM, with histologic evidence suggesting two origins: one from the follicular bulb and one from an intradermal nevus.

    2005-04-01

    Full Text Available Noninvasive real-time in vivo bioluminescent imaging was used to assess the spread of Streptococcus pneumoniae throughout the spinal cord and brain during the acute stages of bacterial meningitis. A mouse model was established by lumbar (LP or intracisternal (IC injection of bioluminescent S. pneumoniae into the subarachnoid space. Bacteria replicated initially at the site of inoculation and spread progressively from the spinal cord to the brain or from the brain down to the cervical part of the spinal column and to the lower vertebral levels. After 24 hr, animals showed strong bioluminescent signals throughout the spinal canal, indicating acute meningitis of the intracranial and intraspinal meninges. A decline in bacterial cell viability, as judged by a reduction in the bioluminescent signal, was observed over time in animals treated with ceftriaxone, but not in untreated groups. Mice treated with the antibiotic survived infection, whereas all mice in untreated groups became moribund, first in the IC group then in the LP group. No untreated animal survived beyond 48 hr after induction of infection. Colony counts of infected cerebrospinal fluid (CSF correlated positively with bioluminescent signals. This methodology is especially appealing because it allows detecting infected mice as early as 3 hr after inoculation, provide temporal, sequential, and spatial distribution of bacteria within the brain and spinal cord throughout the entire disease process and the rapid monitoring of treatment efficacy in a nondestructive manner. Moreover, it avoids the need to sacrifice the animals for CSF sampling and the potential manipulative damage that can occur with other conventional methods.

    Increased anisotropy in brain abscesses has been shown to be due to adhesion of inflammatory cells and is suggestive of an active inflammatory process. The objective of this study was to determine if similar changes occur in the pia-arachnoid on the surface of the cerebral cortex in patients with pyogenic meningitis, and if these changes regress following antibiotic therapy. Diffusion tensor imaging (DTI) was performed on 14 term neonates (mean age 13 days) with bacterial meningitis and 10 healthy age- and sex-matched controls. Regions of interest (ROIs) were placed on areas including the leptomeninges, the cerebral cortex and adjoining subcortical white matter for quantitation of mean fractional anisotropy (FA) and diffusivity (MD) values. Follow-up MRI was performed in five of the neonates in the patient group after 2 weeks of antibiotic treatment. FA and MD values were compared in patients before and after antibiotic treatment as well as with those in the healthy controls. Significantly higher FA values but no difference in MD values were observed in the patient group as compared to the healthy controls at both time points (before and after antibiotic treatment). Significantly decreased FA values in the frontal, occipital and temporal cortical regions were observed in patients following antibiotic treatment. DTI-derived FA may be of value in the noninvasive assessment of meningeal inflammatory activity and treatment response in neonates. (orig.)

  17. Blurring of the vessels of the interhemispheric fissure in multislice CT angiography: a sign of meningeal carcinomatosis

    Ertl-Wagner, Birgit B.; Hoffmann, Ralf-Thorsten; Herrmann, Karin; Reiser, Maximilian F.; Bruening, Roland; Dichgans, Martin

    2004-01-01

    Meningeal carcinomatosis remains a challenging diagnosis to make, with both cerebrospinal fluid (CSF) analysis and radiological methods having a limited sensitivity. We aimed at describing a possible diagnostic sign of multislice CT angiography (MS-CTA) in the diagnosis of meningeal carcinomatosis. Upon retrospective analysis of MSCT angiographies of the brain, a conspicuous sign of the vessels of the interhemispheric fissure was noted in five patients. Cranial MSCT angiographies were performed with a standardized protocol (120 kV, 200 mA s, collimation of 4 x 1 mm, table feed per rotation 4 mm). We injected 120 ml of nonionic contrast medium as a bolus, and data acquisition was started after a fixed delay of 35 s. In order to elucidate the finding, correlation with clinical follow-up and/or CSF findings was performed for all patients. In five patients there was a blurring, an increased number, and a pathologic configuration of the vessels of the interhemispheric fissure. All five patients with this sign had clinical signs and symptoms of meningeal carcinomatosis. Three patients had positive CSF cytology, one further patient had follow-up spinal MRI 6 weeks later demonstrating meningeal carcinomatosis. One patient declined lumbar puncture. MS-CTA has the capacity to demonstrate a pathologic configuration of the vessels of the interhemispheric fissure in patients with meningeal carcinomatosis. This sign may serve as an indicator of meningeal carcinomatosis and should raise the suspicion of this disease entity. (orig.)

  19. Primary multifocal gliosarcoma of the spinal cord

    Ramesh M. Kumar

    2016-03-01

    Full Text Available Gliosarcoma (GS is a rare and exceedingly malignant neoplasm of the central nervous system. It displays clinical features similar to glioblastoma, yet is histologically unique as it harbors both gliomatous and sarcomatous cellular components. Involvement of the neuroaxis is predominantly limited to the cerebral parenchyma and meninges. Primary GS of the spinal cord is rarely encountered. We report a case of a 54 year old male who presented with 2 months of progressive, bilateral lower extremity sensory deficits. Magnetic resonance imaging of the neuro-axis revealed multiple intradural lesions involving the cervical and thoracic spinal cord without evidence of intracranial involvement. Surgical resection of a dural based, extramedullary cervical lesion and two exophytic, intramedullary thoracic lesions revealed gliosarcoma, WHO grade IV. The patient died approximately 11 months after presentation. This report confirms that GS is not limited to supratentorial involvement and can primarily affect the spinal cord.

    Full Text Available This article describes a case of listeria meningitis in a 41-year-old man. At the time of admission to hospital, the patient complained of fever, headache, vomiting, general weakness. An objective examination revealed cervical lymphadenopathy, meningeal signs (positive Kernig’s sign and doubtful rigidity of occipitals, with no focal symptoms. On the right hand it was revealed an abscess in the stage of healing. In the liquor we have detected: pleocytosis — 222 cells with a predominance of neutrophils — 73 %, рrotein — 0.49 g/l, the sugar level in the liquor is slightly reduced. During the bacteriological study of liquor we have isolated Listeria monocytogenes. Serological survey of blood serum using passive hemagglutination test and indirect hemagglutination test revealed levels of antibodies to Listeria monocytogenes — 1 : 800 and 3 (+, respectively.

  2. Multiple Cranial Nerve Involvement In Cryptococcal Meningitis

    2000-01-01

    Full Text Available Cryptococcal meningitis is an uncommon cause of multiple cranial nerve palsies. This case report illustrates one such case of cryptococcal meningitis clinically manifesting with extensive cranial nerve involvement in an HIV seronegative individual. Histology revealed infiltration of the cranial nerves by cryptococci causing axonal disruption with secondary demyelination in the absence of any evidence of inflammation or vasculitis. We believe that axonal damage underlies the pathogenesis of cranial nerve involvement in cryptococcal meningitis.

    Controlling vaccine-preventable infectious diseases is a public health priority in French Guiana but there is currently no epidemiological data on pediatric bacterial meningitis in this overseas department. Our aim was to describe data related to pediatric bacterial meningitis in French Guiana and compare it with that of metropolitan France. We conducted a multicenter retrospective study from 2000 to 2010 to describe the clinical picture, biological data, epidemiology, and outcome of pediatric bacterial meningitis case patients in French Guiana. The median age of bacterial meningitis patients was 6months [0-15] and the sex ratio 1.06. We observed a total of 60 bacterial meningitis case patients. Most presented with pneumococcal meningitis (24 patients; 40%); 11 with Haemophilus influenzae type b meningitis (23%), five with group B streptococcal meningitis (8.5%), and five others (8.5%) with staphylococcal meningitis (three patients presented with coagulase-negative staphylococci and two with Staphylococcus aureus). Only one patient presented with group B meningococcal meningitis, an 18-month-old infant. We recorded 14 deaths (overall case fatality: 23%); eight were due to Streptococcus pneumoniae (case fatality: 33%). The overall sequelae rate was 28%. It was 32% for patients presenting with pneumococcal meningitis. We observed that 38% of children who had never been vaccinated were infected by a vaccine-preventable bacterium. We observed many differences in the distribution of the bacteria and in the patients' prognosis when comparing the French Guiana data with that of metropolitan France. Improving vaccination coverage would decrease the incidence of H. influenzae meningitis. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    In a retrospective cohort of 494 children with meningitis in Sao Paulo, Brazil, the Bacterial Meningitis Score identified all the children with bacterial meningitis (sensitivity 100%, 95% confidence interval: 92-100% and negative predictive value 100%, 95% confidence interval: 98-100%). Addition of cerebrospinal fluid lactate to the score did not improve clinical prediction rule performance.

To date, there has been no documented report of brain abscess as a complication of spinal dermal sinus. Here, we report an 8-month-old girl who was presented initially with a brain abscess at early infancy but lumbar dermal sinus and associated spinal abscess were discovered afterwards. The probable mechanisms of this rare association have been discussed.Keywords: brain abscess, spinal dermal sinus, spinal abscess

  6. Radiation in the treatment of meningeal leukemia

    Jenkin, R.D.

    1979-01-01

    At the present time, a successful regimen for the eradication of occult meningeal leukemia is the combination of cranial radiotherapy in a dose of 1800 rads in 10 fractions in 12 to 14 days with six doses of intrathecal methotrexate. This regimen, when given with prednisone and vincristine can be expected to give a relapse rate for isolated meningeal leukemia of approximately 5% during the first 2 years of follow-up. A modification of this regimen utilizing craniospinal radiation with prior and concurrent intrathecal methotrexate is given for the treatment of overt meningeal leukemia at diagnosis or for an isolated first relapse with meningeal leukemia. Radiation technique and morbidity are discussed

  7. Supporting meningitis diagnosis amongst infants and children through the use of fuzzy cognitive mapping

    2012-01-01

    Background Meningitis is characterized by an inflammation of the meninges, or the membranes surrounding the brain and spinal cord. Early diagnosis and treatment is crucial for a positive outcome, yet identifying meningitis is a complex process involving an array of signs and symptoms and multiple causal factors which require novel solutions to support clinical decision-making. In this work, we explore the potential of fuzzy cognitive map to assist in the modeling of meningitis, as a support tool for physicians in the accurate diagnosis and treatment of the condition. Methods Fuzzy cognitive mapping (FCM) is a method for analysing and depicting human perception of a given system. FCM facilitates the development of a conceptual model which is not limited by exact values and measurements and thus is well suited to representing relatively unstructured knowledge and associations expressed in imprecise terms. A team of doctors (physicians), comprising four paediatricians, was formed to define the multifarious signs and symptoms associated with meningitis and to identify risk factors integral to its causality, as indicators used by clinicians to identify the presence or absence of meningitis in patients. The FCM model, consisting of 20 concept nodes, has been designed by the team of paediatricians in collaborative dialogue with the research team. Results The paediatricians were supplied with a form containing various input parameters to be completed at the time of diagnosing meningitis among infants and children. The paediatricians provided information on a total of 56 patient cases amongst children whose age ranged from 2 months to 7 years. The physicians’ decision to diagnose meningitis was available for each individual case which was used as the outcome measure for evaluating the model. The FCM was trained using 40 cases with an accuracy of 95%, and later 16 test cases were used to analyze the accuracy and reliability of the model. The system produced the results

  8. SPINAL CORD- A CADAVERIC STUDY

    Vijayamma K. N

    2018-01-01

    Full Text Available BACKGROUND Spinal cord is situated within the vertebral canal extending from the lower end of the medulla oblongata at the upper border of first cervical vertebra. In early foetal life, it extends throughout the length of the vertebral canal, and at the time of birth, it reaches the level of third lumbar vertebra. In adult, it ends at the lower border of first lumbar vertebra and thereafter continued as filum terminale, which gets attached to tip of coccyx. Spinal cord is covered by three protective membranes called spinal meninges, diameter, arachnoid and pia mater. The diameter and arachnoid mater extent up to second sacral vertebra and the pia mater forms filum terminale and extend at the tip of coccyx. MATERIALS AND METHODS Forty spinal cord cadaveric specimen were studied by dissection method after exposing the vertebral canal. The roots of spinal nerve were sectioned on both sides and the cord is released along with its coverings. The dura and arachnoid mater were incised longitudinally and the subarachnoid space, blood vessels, nerve roots, ligament denticulata, cervical and lumbar enlargements were observed. The blood vessels including radicular arteries were also studied photographed. RESULTS The spinal cord is a highly vascular structure situated within the vertebral canal, covered by diameter, arachnoid mater and pia mater. Spinal dura is thicker anteriorly than posteriorly. The pia mater forms linea splendens, which extend along the whole length of the cord in front of the anterior median fissure. The average length of the cord is 38 cm. The length and breadth of cervical enlargement was more compared to lumbar enlargement. The number of rootlets in both dorsal and ventral roots accounts more in cervical compared to other regions of the cord. The ligament denticulata is a thin transparent bands of pia mater attached on either sides of the cord between the dorsal and ventral roots of spinal nerves. The tooth like extensions are well

    participants; moderate-certainty evidence), but may reduce neurological disability (RR 0.73, 95% CI 0.53 to 1.00; 5 studies, 1270 participants; low-certainty evidence). Glycerol may have little or no effect on seizures during treatment for meningitis (RR 1.08, 95% CI 0.90 to 1.30; 4 studies, 1090 participants; low-certainty evidence). Glycerol may reduce the risk of subsequent deafness (RR 0.64, 95% CI 0.44 to 0.93; 5 studies, 922 participants; low to moderate-certainty evidence). Glycerol probably has little or no effect on gastrointestinal bleeding (RR 0.93, 95% CI 0.39 to 2.19; 3 studies, 607 participants; moderate-certainty evidence). The evidence on nausea, vomiting and diarrhoea is uncertain (RR 1.09, 95% CI 0.81 to 1.47; 2 studies, 851 participants; very low-certainty evidence). Authors' conclusions Glycerol was the only osmotic therapy evaluated, and data from trials to date have not demonstrated an effect on death. Glycerol may reduce neurological deficiency and deafness. Osmotic therapies added to antibiotics for acute bacterial meningitis What is the aim of this review? The aim of this Cochrane Review is to collect and analyse trials evaluating osmotic therapies given orally or intravenously to people with acute bacterial meningitis. Cochrane authors collected and analysed all relevant studies to answer this question; they found five relevant studies. Key messages Giving glycerol, an osmotic diuretic, probably has little or no effect on death (moderate-certainty evidence), but may reduce subsequent deafness (moderate-certainty evidence) or neurological disability (low-certainty evidence). The evidence is current to 17 February 2017. What was studied in the review? In meningitis, the cerebrospinal fluid that surrounds the brain and spinal cord is infected, usually as a result of spread from the blood. Any form of meningitis can result in death or severe disability, but acute bacterial meningitis is rapidly fatal without treatment. Even with antibiotics, 10% to 15% of

  11. Cerebrospinal fluid flow abnormalities in patients with neoplastic meningitis. An evaluation using 111In-DTPA ventriculography

    Grossman, S.A.; Trump, D.L.; Chen, D.C.; Thompson, G.; Camargo, E.E.

    1982-01-01

    Cerebrospinal fluid flow dynamics were evaluated by 111 In-diethylenetriamine pentaacetic acid ( 111 In-DTPA) ventriculography in 27 patients with neoplastic meningitis. Nineteen patients (70 percent) had evidence of cerebrospinal fluid flow disturbances. These occurred as ventricular outlet obstructions, abnormalities of flow in the spinal canal, or flow distrubances over the cortical convexities. Tumor histology, physical examination, cerebrospinal fluid analysis, myelograms, and computerized axial tomographic scans were not sufficient to predict cerebrospinal fluid flow patterns. These data indicate that cerebrospinal fluid flow abnormalities are common in patients with neoplastic meningitis and that 111 In-DTPA cerebrospinal fluid flow imaging is useful in characterizing these abnormalities. This technique provides insight into the distribution of intraventricularly administered chemotherapy and may provide explanations for treatment failure and drug-induced neurotoxicity in patients with neoplastic meningitis

  12. Endocarditis in adults with bacterial meningitis.

    2013-05-21

    Endocarditis may precede or complicate bacterial meningitis, but the incidence and impact of endocarditis in bacterial meningitis are unknown. We assessed the incidence and clinical characteristics of patients with meningitis and endocarditis from a nationwide cohort study of adults with community-acquired bacterial meningitis in the Netherlands from 2006 to 2012. Endocarditis was identified in 24 of 1025 episodes (2%) of bacterial meningitis. Cultures yielded Streptococcus pneumoniae in 13 patients, Staphylococcus aureus in 8 patients, and Streptococcus agalactiae, Streptococcus pyogenes, and Streptococcus salivarius in 1 patient each. Clues leading to the diagnosis of endocarditis were cardiac murmurs, persistent or recurrent fever, a history of heart valve disease, and S aureus as the causative pathogen of bacterial meningitis. Treatment consisted of prolonged antibiotic therapy in all patients and surgical valve replacement in 10 patients (42%). Two patients were treated with oral anticoagulants, and both developed life-threatening intracerebral hemorrhage. Systemic (70%) and neurological (54%) complications occurred frequently, leading to a high proportion of patients with unfavorable outcome (63%). Seven of 24 patients (29%) with meningitis and endocarditis died. Endocarditis is an uncommon coexisting condition in bacterial meningitis but is associated with a high rate of unfavorable outcome.

    Full Text Available Objective: Enterovirus 71(EV 71 causes wide spectrum of infections ranging from asymptomatic conditions to clinical syndromes like diarrhea, rash, hand-foot-and mouth disease (HFMD, herpangina, aseptic meningitis, encephalitis, myocarditis, acute flaccid paralysis, bulbar and brainstem encephalitis Guillain Barre syndrome, pulmonary haemorrhage. This study deals with an outbreak of aseptic meningitis in children caused by EV 71 virus. Methods: The authors report an outbreak of aseptic meningitis in children in and around Calicut in June 2008. Clinical and laboratory study was done in collaboration with National Centre for Disease Control, New Delhi. 149 children with aseptic meningitis were studied and followed up from June 2008 to May 2009. Result: All children had clinical features suggestive of aseptic meningitis and serology showed the rising antibody titre against EV 71 virus infection. CSF analysis also showed four fold rise in antibodies in one and ≥ 1:2 neutralising antibodies titer against EV- 71 in four samples indicating meningitis due to EV-71. Conclusion: EV 71 was identified as the causative agent of the outbreak of aseptic meningitis in the study and the fact that the EV 71 infection has evolved from minor illness like HFMD to major illness like aseptic meningitis from the same locality is truly alarming.

    2011-02-01

    In the central nervous system of patients with multiple sclerosis, B cell aggregates populate the meninges, raising the central question as to whether these structures relate to the B cell infiltrates found in parenchymal lesions or instead, represent a separate central nervous system immune compartment. We characterized the repertoires derived from meningeal B cell aggregates and the corresponding parenchymal infiltrates from brain tissue derived primarily from patients with progressive multiple sclerosis. The majority of expanded antigen-experienced B cell clones derived from meningeal aggregates were also present in the parenchyma. We extended this investigation to include 20 grey matter specimens containing meninges, 26 inflammatory plaques, 19 areas of normal appearing white matter and cerebral spinal fluid. Analysis of 1833 B cell receptor heavy chain variable region sequences demonstrated that antigen-experienced clones were consistently shared among these distinct compartments. This study establishes a relationship between extraparenchymal lymphoid tissue and parenchymal infiltrates and defines the arrangement of B cell clones that populate the central nervous system of patients with multiple sclerosis.

    Spinal cysticercosis is an extremely uncommon condition. We have examined four patients with complaints that resembled nervous root compression by disk herniation. Myelography was shown to be an efficient method to evaluate spinal involvement, that was characterized by findings of multiple filling defect images (cysts) plus signs of adhesive arachnoiditis. One cyst was found to be mobile. Because of the recent development of medical treatment, a quick and precise diagnosis is of high importance to determine the prognosis of this condition. (author)

  5. Meningitis and encephalitis in Poland in 2014

    Paradowska-Stankiewicz, Iwona; Piotrowska, Anna

    The aim of this study was to assess the epidemiology of meningitis and/or encephalitis in Poland in 2014. In the last three years in Poland, about 3000 cases of meningitis and/or encephalitis of viral or bacterial etiology were recorded annually. Assessment of the epidemiological situation of meningitis and/or encephalitis in Poland in 2014, was based on the results of the analysis of epidemiological reports sent to the NIZP-PZH by the Regional Sanitary-Epidemiological Stations published in the annual bulletin “Infectious diseases and poisonings in Poland in 2014” and “Preventive immunizations in Poland in 2014”. In 2014 in Poland 3488 cases of bacterial meningitis and/or encephalitis were recorded. Almost 61.3% of these were viral infections. In 2014, in comparison to 2013, a 1.1% increase in the number of cases of meningitis and/or encephalitis was observed and 91% with viral etiology.

    Full Text Available Foram estudados 3 casos de carcinomatose das meninges, autopsiados no serviço de Anatomia Patológica do Hospital Prof. Edgard Santos. O quadro neurológico apresentado era proeminente e representado por sinto- matologia decorrente do envolvimento meníngeo e encefálico, razão pela qual foram considerados como portadores de meningite tuberculosa e encefalomielite. O aspecto de maior interesse neste estudo foi a discrepância entre o quadro clínico e os dados anátomo-patológicos do exame do encéfalo. A sintomatologia clínica foi proeminente, enquanto as lesões anatômicas foram apenas discretas ou moderadas e representadas por espessamento e granulosidade das meninges, com infiltração difusa do espaço subaracnoideano pela neoplasia. Nos casos 1 e 3 a neoplasia estava representada por adenocarcinoma, cujos focos primitivos foram localizados no pulmão e vesícula biliar, respectivamente. O caso 2 era um carcinoma indiferenciado do estômago, com envolvimento difuso do espaço subaracnoideano e subdural, havendo neste último extensa hemorragia recente. Os critérios diagnósticos e a maneira de disseminação desta condição são discutidos.A diffuse involvement of the meninges by carcinoma is described in three cases characterizing the so called "meningeal carcinomatosis". The neurologic symptoms were those of the chronic meningitis or encephalomyelitis, with changes in the spinal fluid. The morphologic features were identical in the three cases and represented by slight to moderate thickening of the meninges by diffuse infiltration of tumor cells and few foci of inflamatory reaction. The cases 1 and 3 were represented by well differentiated adenocarcinoma with primary site in the lung and gallbladder, respectively. In case 2 the tumor was a poorly differentiated carcinoma of stomach with diffuse involvement of the arachnoid and dura mater associated with recent hemorrhage. An interesting point was the lack of correlation between

    Central nervous system (CNS) involvement by rheumatoid arthritis (RA) in the form of rheumatoid meningitis (RM) is rare and most commonly occurs in the setting of longstanding severe RA. Due to a wide range of clinical presentations and nonspecific laboratory findings, it presents a diagnostic challenge often requiring brain biopsy. Only a few histopathologically confirmed cases have been described in the literature. Our aim is to describe two cases of RM and review the literature. The first case is of a previously healthy 37-year-old man who presented with severe headaches and focal neurologic deficits. Magnetic resonance imaging demonstrated abnormal leptomeningeal enhancement in the left frontal and parietal sulci. The second case is of a 62-year-old woman with a history of mild chronic joint pain who presented with confusion, personality changes and seizures. Both patients ultimately underwent brain biopsy which demonstrated RM on pathologic examination. Administration of corticosteroids resulted in significant clinical improvement in both cases. To our knowledge, our unusual case of RM in the young man is the fifth reported case of rheumatoid meningitis in a patient with no prior history of RA. Such an atypical presentation makes diagnosis even more difficult and highlights the need for awareness of this entity in the diagnostic consideration of a patient presenting with unexplained neurologic symptoms. Our literature review underscores the clinical and pathologic heterogeneity of CNS involvement in RA. © 2015 Japanese Society of Neuropathology.

  11. In Brief: Forecasting meningitis threats

    Showstack, Randy

    2008-12-01

    The University Corporation for Atmospheric Research (UCAR), in conjunction with a team of health and weather organizations, has launched a project to provide weather forecasts to medical officials in Africa to help reduce outbreaks of meningitis. The forecasts will enable local health care providers to target vaccination programs more effectively. In 2009, meteorologists with the National Center for Atmospheric Research, which is managed by UCAR, will begin issuing 14-day forecasts of atmospheric conditions in Ghana. Later, UCAR plans to work closely with health experts from several African countries to design and test a decision support system to provide health officials with useful meteorological information. ``By targeting forecasts in regions where meningitis is a threat, we may be able to help vulnerable populations. Ultimately, we hope to build on this project and provide information to public health programs battling weather-related diseases in other parts of the world,'' said Rajul Pandya, director of UCAR's Community Building Program. Funding for the project comes from a $900,000 grant from Google.org, the philanthropic arm of the Internet search company.

    2014-07-14

    The purpose of this study was to present the epidemiologic features of bacterial meningitis in the developing country of Kosovo. Data were collected from active surveillance of bacterial meningitis cases treated at the University Clinical Center of Kosovo in the years 2000 (first post-war year) and 2010. Meningitis cases in 2000 compared with 2010 showed a 35.5% decline in incidence (from 4.8 to 3.1 cases per 100,000 population) and a decrease in the case fatality rate from 10% to 5%. In children, there was a lower mortality rate (5% versus 2%) and a lower incidence of neurological complications (13% versus 16%) as compared to adults (32% versus 10% and 16% versus 35%, respectively). Neisseria meningitidis was the most common pathogen of bacterial meningitis in both study periods. Bacterial meningitis was most prevalent in the pediatric population, and showed an increase in the median age, from three years in 2000 to seven years in 2010. A steady number of bacterial meningitis cases in adults throughout last decade (around 20 cases per year) was recorded. During the last decade, gradual changes have been observed in the epidemiology of bacterial meningitis that are unrelated to the introduction of new vaccines, but are partly due to the improvement of living conditions.

  13. An interesting case of primary spinal arachnoiditis.

    Vaughan, Denis

    2012-02-27

    Spinal arachnoiditis describes inflammation of the meninges, subarachnoid space and, in most cases, also involve the pial layer. The vast majority of cases described are secondary and are preceded by a known event, for example,. trauma, infections or irritative substances. Here, we present the case of primary spinal arachnoiditis. A 35-year-old lady was referred to the neurosurgical services in Dublin, Ireland with a 15-month history of progressive, right lower limb weakness. Magnetic resonance imaging revealed cystic distortion of the lumbar spinal canal extending up to the conus. Initially, an L2-L4 laminectomy was performed revealing thickened and adherent arachnoid with a large cyst in the spinal canal. Four months after initial operation, the patient represented with bilateral lower limb weakness and loss of detrusor function. Repeat magnetic resonance imaging was performed, which showed the development of a syrinx in the patient\\'s thoracic spine. We then performed a T9-T10 laminectomy, midline myelotomy and insertion of a syringe-arachnoid shunt. Post-operative imaging showed resolution of the syrinx and a vast improvement in lower limb power. The patient also regained bladder control. In conclusion, spinal arachnoiditis is a clearly defined pathological and radiological entity with a highly variable clinical presentation. It is exceedingly difficult to treat as there is no recognised treatment currently, with most interventions aimed at symptomatic relief.

    Spinal tumors are uncommon lesions but may cause significant morbidity in terms of limb dysfunction. In establishing the differential diagnosis for a spinal lesion, location is the most important feature, but the clinical presentation and the patient's age and gender are also important. Magnetic resonance (MR) imaging plays a central role in the imaging of spinal tumors, easily allowing tumors to be classified as extradural, intradural-extramedullary or intramedullary, which is very useful in tumor characterization. In the evaluation of lesions of the osseous spine both computed tomography (CT) and MR are important. We describe the most common spinal tumors in detail. In general, extradural lesions are the most common with metastasis being the most frequent. Intradural tumors are rare, and the majority is extramedullary, with meningiomas and nerve sheath tumors being the most frequent. Intramedullary tumors are uncommon spinal tumors. Astrocytomas and ependymomas comprise the majority of the intramedullary tumors. The most important tumors are documented with appropriate high quality CT or MR images and the characteristics of these tumors are also summarized in a comprehensive table. Finally we illustrate the use of the new World Health Organization (WHO) classification of neoplasms affecting the central nervous system

  15. Meninges: from protective membrane to stem cell niche

    Decimo, Ilaria; Fumagalli, Guido; Berton, Valeria; Krampera, Mauro; Bifari, Francesco

    2012-01-01

    Meninges are a three tissue membrane primarily known as coverings of the brain. More in depth studies on meningeal function and ultrastructure have recently changed the view of meninges as a merely protective membrane. Accurate evaluation of the anatomical distribution in the CNS reveals that meninges largely penetrate inside the neural tissue. Meninges enter the CNS by projecting between structures, in the stroma of choroid plexus and form the perivascular space (Virchow-Robin) of every pare...

  16. Is repair of the protruded meninges sufficient for treatment of meningocele?

    Yun-Hai, Song; Nan, Bao; Ping-Ping, Gao; Bo, Yang; Cheng, Chen

    2015-11-01

    The present study aimed to investigate the relationship between meningocele and tethered cord syndrome, diagnosis of meningocele associated with tethered cord syndrome, and when to perform surgery and the best surgical procedure. Sixty-nine children with meningocele who were admitted to Shanghai Children's Medical Center were analyzed. The relationship between meningocele and other lesions causing tethered cord syndrome was studied by combining magnetic resonance imaging (MRI) and intraoperative findings. The MRI results and intraoperative findings showed that 67 children (97%) had associated lesions such as tight filum terminale, fibrous band tethering, spinal cord or cauda equina adhesion, diastematomyelia, arachnoid cyst, and epidermoid cyst. The protruded meninges were repaired, and the intraspinal lesions were treated at the same time. Also, the tethered spinal cord was released. No neurological injuries were observed after surgery. The rate of meningocele associated with tethered cord syndrome is very high. MRI is necessary for the diagnosis of meningocele. Active surgical treatment is recommended immediately after definite diagnosis. During surgery, the surgeon should not only repair the protruded meninges but also explore the spinal canal and release the tethered cord.

  17. Chronic Meningitis: Simplifying a Diagnostic Challenge.

    Baldwin, Kelly; Whiting, Chris

    2016-03-01

    Chronic meningitis can be a diagnostic dilemma for even the most experienced clinician. Many times, the differential diagnosis is broad and encompasses autoimmune, neoplastic, and infectious etiologies. This review will focus on a general approach to chronic meningitis to simplify the diagnostic challenges many clinicians face. The article will also review the most common etiologies of chronic meningitis in some detail including clinical presentation, diagnostic testing, treatment, and outcomes. By using a case-based approach, we will focus on the key elements of clinical presentation and laboratory analysis that will yield the most rapid and accurate diagnosis in these complicated cases.

  18. Spinal tuberculosis.

    Dunn, R N; Ben Husien, M

    2018-04-01

    Tuberculosis (TB) remains endemic in many parts of the developing world and is increasingly seen in the developed world due to migration. A total of 1.3 million people die annually from the disease. Spinal TB is the most common musculoskeletal manifestation, affecting about 1 to 2% of all cases of TB. The coexistence of HIV, which is endemic in some regions, adds to the burden and the complexity of management. This review discusses the epidemiology, clinical presentation, diagnosis, impact of HIV and both the medical and surgical options in the management of spinal TB.

    2012-04-15

    Background: Infarctions in tuberculous meningitis (TBM) are common but there is a paucity of studies on MR angiography (MRA). Purpose: To evaluate the pattern and predictors of MRA abnormality in patients with TBM. Material and Methods: Sixty-seven patients with TBM were subjected to clinical, laboratory, magnetic resonance imaging (MRI), and MRA evaluation. The severity of meningitis, focal deficit, CSF findings, and stroke co-morbidities were recorded. Presence of exudates, infarction, hydrocephalous, and tuberculoma on MRI were noted. On intracranial MRA, occlusion or more than 50% narrowing of proximal middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA), and basilar artery were considered abnormal. The MRA abnormality was correlated with clinical, laboratory, and MRI findings. Results: Sixty-seven patients, aged 3-75 years (median 34 years) were included. MRI was abnormal in 61 (91%) patients; basal exudates in 24, hydrocephalous in 23, tuberculoma in 33, and infarction in 40. MRA was abnormal in 34 (50.7%); MCA was most commonly involved (n = 21), followed by PCA (n = 14), ICA (n = 8), ACA (n 5), basilar artery (n = 5), and vertebral and superior cerebellar artery (1 each). One-fourth of the patients had abnormality in both anterior and posterior circulations. MRA abnormality was related to hydrocephalous and infarction; corresponding infarct was present in 61.8% patients; 41.7% patients with abnormal MRA developed infarct at 3 months but none with normal MRA. Conclusion: Half the patients with TBM had MRA abnormality involving both anterior and posterior circulations and 61.8% of them had corresponding infarcts

    2015-01-01

    The commonest sequelae of bacterial meningitis are related to the inner ear. Little is known about the inner ear immune defense. Evidence suggests that the endolymphatic sac provides some protection against infection. A potential involvement of the endolymphatic sac in bacterial meningitis...... is largely unaccounted for, and thus the object of the present study. A well-established adult rat model of Streptococcus pneumoniae meningitis was employed. Thirty adult rats were inoculated intrathecally with Streptococcus pneumoniae and received no additional treatment. Six rats were sham...... days. Bacteria invaded the inner ear through the cochlear aquaduct. On days 5-6, the bacteria invaded the endolymphatic sac through the endolymphatic duct subsequent to invasion of the vestibular endolymphatic compartment. No evidence of direct bacterial invasion of the sac through the meninges...

  6. [The meninges, an anatomical point of view].

    Sakka, L; Chazal, J

    2005-03-01

    The meninges correspond to an anatomical concept. For the morphologist, the microscopic organization, the hypothetical presence of a subdural space, the nature of the interface between the deep meningeal layer and the nervous parenchyma in the perivascular spaces are the central issues. For the clinician, dynamic aspects of cerebrospinal fluid flow, secretion, and resorption are essential factors with practical consequences in terms of disease and patient management. Comparative anatomy, embryology, and organogenesis provide an interesting perspective for the descriptive and functional anatomy of the meninges. Usually considered as protective membranes, the meninges play a prominent role in the development and maintenance of the central nervous system. The meninges are in constant evolution, from their formation to senescence. The meninges present three layers in children and adults: the dura mater, the arachnoid and the pia mater. The cerebrospinal fluid is secreted by the choroid plexuses, flows through the ventricles and the subarachnoid space, and is absorbed by arachnoid granulations. Other sites of secretion and resorption are suggested by comparative anatomy and human embryology and organogenesis.

  7. Enteroviral Meningitis: Peculiarities of the Course and Diagnosis at the Present Stage

    L.R. Shostakovych-Koretskaya

    2016-11-01

    Full Text Available Background. Enteroviral infection is characterized by a variety of clinical forms: non-specific enterovirus fever, herpangina, hand-foot-and-mouth disease, pleurodynia, meningitis, gastroenteritis, nonspecific enteroviral rash. Enteroviral meningitis is the most urgent clinical form of enteroviral infection, usually with a favorable course and mild to moderate severity. Materials and methods. A retrospective analysis of case histories of 44 children diagnosed with confirmed enteroviral meningitis was performed in this work. Diagnosis of enteroviral meningitis was verified by detection of viral RNA in cerebro-spinal fluid in all patients with polymerase chain reaction method. Age of patients ranged from 3 to 17 years, males and females distribution was close to equal. In addition to routine examinations, in some patients electrocardiography (ECG was conducted. Results. One-third of patients (n = 10; 30.3 % showed some changes on ECG, characteristic of myocarditis, in the absence of clinical manifestations of heart disease. This fact points to the need for more careful attention to the diagnosis of mild clinically forms of myocarditis in patients with enteroviral infection that allows recommend the inclusion into the mandatory algorithm of examination of the cardiac pathology with the following activities: conducting ECG studies and research of biochemical cardiac markers (creatine phosphokinase-MB, troponin I, aspartate aminotransferase, alanine transaminase, lactic dehydrogenasefraction. In our study, ECG was performed in 13 patients (39.4 %. Of these, 10 patients (30.3 % had evidence of heart disease on the ECG with absence of any clinical manifestation suggestive of heart involvement. Conclusions. Epidemiology of enteroviral meningitis preserves its typical features of summer-autumn seasonal pattern, dominant position in the etiological structure of meningitis and most common involvement of pre-pubertate age children (7 to 12 years. In all

  8. Modeling tuberculous meningitis in zebrafish using Mycobacterium marinum

    Lisanne M. van Leeuwen

    2014-09-01

    Full Text Available Tuberculous meningitis (TBM is one of the most severe extrapulmonary manifestations of tuberculosis, with a high morbidity and mortality. Characteristic pathological features of TBM are Rich foci, i.e. brain- and spinal-cord-specific granulomas formed after hematogenous spread of pulmonary tuberculosis. Little is known about the early pathogenesis of TBM and the role of Rich foci. We have adapted the zebrafish model of Mycobacterium marinum infection (zebrafish–M. marinum model to study TBM. First, we analyzed whether TBM occurs in adult zebrafish and showed that intraperitoneal infection resulted in granuloma formation in the meninges in 20% of the cases, with occasional brain parenchyma involvement. In zebrafish embryos, bacterial infiltration and clustering of infected phagocytes was observed after infection at three different inoculation sites: parenchyma, hindbrain ventricle and caudal vein. Infection via the bloodstream resulted in the formation of early granulomas in brain tissue in 70% of the cases. In these zebrafish embryos, infiltrates were located in the proximity of blood vessels. Interestingly, no differences were observed when embryos were infected before or after early formation of the blood-brain barrier (BBB, indicating that bacteria are able to cross this barrier with relatively high efficiency. In agreement with this observation, infected zebrafish larvae also showed infiltration of the brain tissue. Upon infection of embryos with an M. marinum ESX-1 mutant, only small clusters and scattered isolated phagocytes with high bacterial loads were present in the brain tissue. In conclusion, our adapted zebrafish–M. marinum infection model for studying granuloma formation in the brain will allow for the detailed analysis of both bacterial and host factors involved in TBM. It will help solve longstanding questions on the role of Rich foci and potentially contribute to the development of better diagnostic tools and therapeutics.

  9. Central projections of the sensory innervation of the rat middle meningeal artery

    Liu, Y.; Broman, J.; Edvinsson, L.

    2008-01-01

    Headaches, especially migraine, involve not only pain but also aspects such as vasodilation of cranial vessels and sensitization of nerve endings, processes dependent on and connected to the central nervous system. To understand pathogenic mechanisms of headache, it is important to elucidate...... the central projections of sensory nerves that innervate cranial vessels, of which the middle meningeal artery (MMA) is the largest artery supplying the dura mater. In this study, cholera toxin subunit b (CTb) or wheat germ agglutinin-horseradish peroxidase conjugate (WGA-HRP) was applied on the adventitia....... Labeled nerve terminations were found ipsilaterally in the lateral part of the spinal dorsal horn of segments C1-C3 and in the caudal and interpolar parts of the spinal trigeminal nucleus. WGA-HRP labeled terminations were mainly located in laminae I and II, whereas CTb labeled terminations located...

  10. Meningitis and Climate: From Science to Practice

    Perez Garcia-Pando, Carlos; Thomson, Madeleine C.; Stanton, Michelle C.; Diggle, Peter J.; Hopson, Thomas; Pandya, Rajul; Miller, Ron L.; Hugonnet, Stephane

    2014-01-01

    Meningococcal meningitis is a climate sensitive infectious disease. The regional extent of the Meningitis Belt in Africa, where the majority of epidemics occur, was originally defined by Lapeysonnie in the 1960s. A combination of climatic and environmental conditions and biological and social factors have been associated to the spatial and temporal patterns of epidemics observed since the disease first emerged in West Africa over a century ago. However, there is still a lack of knowledge and data that would allow disentangling the relative effects of the diverse risk factors upon epidemics. The Meningitis Environmental Risk Information Technologies Initiative (MERIT), a collaborative research-to-practice consortium, seeks to inform national and regional prevention and control strategies across the African Meningitis Belt through the provision of new data and tools that better determine risk factors. In particular MERIT seeks to consolidate a body of knowledge that provides evidence of the contribution of climatic and environmental factors to seasonal and year-to-year variations in meningococcal meningitis incidence at both district and national scales. Here we review recent research and practice seeking to provide useful information for the epidemic response strategy of National Ministries of Health in the Meningitis Belt of Africa. In particular the research and derived tools described in this paper have focused at "getting science into policy and practice" by engaging with practitioner communities under the umbrella of MERIT to ensure the relevance of their work to operational decision-making. We limit our focus to that of reactive vaccination for meningococcal meningitis. Important but external to our discussion is the development and implementation of the new conjugate vaccine, which specifically targets meningococcus A

    Spinal cord injury is a major cause of disability with devastating neurological outcomes and limited therapeutic opportunities, even though there are thousands of publications on spinal cord injury annually. There are two major types of spinal cord injury, transaction of the spinal cord and spinal cord contusion. Both can theoretically be treated, but there is no well documented treatment in human being. As for spinal cord contusion, we have developed an operation with fabulous result.

  1. Meningitis in a Chinese adult patient caused by Mycoplasma hominis: a rare infection and literature review.

    Zhou, Menglan; Wang, Peng; Chen, Sharon; Du, Bin; Du, Jinlong; Wang, Fengdan; Xiao, Meng; Kong, Fanrong; Xu, Yingchun

    2016-10-12

    Mycoplasma hominis, a well known cause of neonatal infection, has been reported as a pathogen in urogenital infections in adults; however, central nervous system (CNS) infections are rare. We report here the first case of M. hominis meningitis in China, post neurosurgical treatment for an intracerebral haemorrhage in a 71-year-old male. We describe a 71-year-old man who developed M. hominis meningitis after neurosurgical treatment and was successfully treated with combined azithromycin and minocycline therapy of 2 weeks duration, despite delayed treatment because the Gram stain of cerebrospinal fluid (CSF) yielded no visible organisms. The diagnosis required 16S rDNA sequencing analysis of the cultured isolate from CSF. Literature review of M. hominis CNS infections yielded 19 cases (13 instances of brain abscess, 3 of meningitis, 1 spinal cord abscess and 1 subdural empyema each). Delay in diagnosis and initial treatment failure was evident in all cases. With appropriate microbiological testing, antibiotic therapy (ranging from 5 days to 12 weeks) and often, multiple surgical interventions, almost all the patients improved immediately. Both our patient findings and the literature review, highlighted the pathogenic potential of M. hominis together with the challenges prompted by rare infectious diseases in particular for developing countries laboratories with limited diagnostic resources.

    Valappil, Ashraf V; Thiruvoth, Sohanlal; Peedikayil, Jabir M; Raghunath, Praveenkumar; Thekkedath, Manojan

    2017-12-01

    The involvement of the central nervous system in the form of meningitis or meningoencephalitis is common in scrub typhus and is an important differential diagnosis of other lymphocytic meningitis like tuberculous meningitis (TBM). The aim of this study was to identify the clinical and laboratory parameters that may be helpful in differentiating scrub typhus meningitis from TBM. We compared of the clinical and laboratory features of 57 patients admitted with scrub typhus meningitis or TBM during a 3-year period. Patients who had abnormal cerebrospinal fluid (CSF) and positive scrub typhus enzyme-linked immunosorbent assay serology (n=28) were included in the scrub typhus meningitis group, while the TBM group included those who satisfied the consensus diagnostic criteria of TBM (n=29). Compared with the TBM group, the mean duration of symptoms was less in patients with scrub typhus meningitis, who also had a lower magnitude of neurological deficits, such as altered mental status and cranial nerve and motor deficits. Patients with scrub typhus meningitis had a lower CSF white blood-cell count (WBC) than the TBM group (130.8±213 195±175 cells/mm 3 , P=0.002), lower CSF protein elevation (125±120 vs. 195.2±108.2mg/dl, P=0.002), and higher CSF sugar (70.1±32.4 vs. 48.7±23.4mg/dl, P=0.006). Features predictive of the diagnosis of scrub typhus meningitis included the absence of neurological impairment at presentation, blood serum glutamic-oxaloacetic transaminase>40 international units (IU)/L, serum glutamic-pyruvic transaminase>60 IU/L, total blood leukocyte count>10,000/mm 3 , CSF protein50mg/dl, CSF WBC<100 cells/mm 3 . All patients with scrub typhus meningitis recovered completely following doxycycline therapy CONCLUSIONS: This study suggests that, clinical features, including duration of fever, neurological deficits at presentation and laboratory parameters such as CSF pleocytosis,CSF protein elevation, CSF sugar levels and liver enzyme values are helpful in

  6. Meningeal enhancement on MRI after craniotomy

    Nomura, Motohiro; Hasegawa, Mitsuhiro; Yamashima, Tetsumori; Yamashita, Junkoh; Suzuki, Masayuki

    1991-01-01

    Gd-DPTA-enhanced MR images in 94 patients who had undergone craniotomy were studied, with particular attention paid to the meningeal enhancement. Such enhancement was noted in 26 of the 94 (27.6%) in the portion surrounding the craniotomy site. Meningeal enhancement, presumably of the subdural neomembrane, was apparent as a third line of a high signal intensity on T 1 -weighted MR images. The outer two high-intensity lines were derived from fat in the subcutaneous tissues of the scalp and fat in the bone marrow of the calvaria. We designated this characteristic enhancement as a 'triple white line'. Of the 26 patients with meningeal enhancement, 22 cases (23.4%) showed such a 'triple white line', 11 cases (11.7%) showed falx enhancement, and 12 cases (12.8%) showed tentorial enhancement. The intervals between surgery and the appearance of the meningeal enhancement ranged from 4 days to 88 weeks. A small amount of bleeding into the dura-arachnoid interface induced by surgery might result in the subdural neomembrane, as has previously been reported. This neomembrane might be enhanced by the leakage of Gd-DTPA through the proliferating capillaries. As meningeal enhancement occurs in approximately a third of the cases following craniotomy, much care should be taken in the differential diagnosis of the infection, inflammation, and metastasis or dissemination of malignant brain tumors.

  7. MR imaging of the meningeal diseases

    Schoerner, W.; Henkes, H.; Felix, R.

    1988-01-01

    The value of MR imaging in the diagnosis of meningeal diseases was studied in 22 patients with various meningeal alterations (tumor, inflammation, trauma, radiation). MR studies (0.5 T) included T2-weighted (spin echo [SE] 1,600/70 [repetition time msec/echo time msec]) images in 20 of 22 patients and T1-weighted images (SE 400/30) in all patients, before and after Gd-DTPA enhancement. As compared with a control group (20 cases), 16 of 20 T2-weighted studies of the patient group showed pathologically increased signal intensity of the subarchnoidal space. Whereas only normal findings were seen on T1-weighted images in the patient group, 21 of 22 patients had pathologically increased contrast accumulation of the meninges. In conclusion, pathologic changes of the meninges could be demonstrated on plain T2-weighted and contrast-enhanced T1-weighted images. In selected cases, detection of meningeal disease could be achieved only with Gd-DTPA-enhanced studies

  8. Human Meningitis-Associated Escherichia coli

    KIM, KWANG SIK

    2016-01-01

    E. coli is the most common Gram-negative bacillary organism causing meningitis and E. coli meningitis continues to be an important cause of mortality and morbidity throughout the world. Our incomplete knowledge of its pathogenesis contributes to such mortality and morbidity. Recent reports of E. coli strains producing CTX-M-type or TEM-type extended-spectrum β-lactamases create a challenge. Studies using in vitro and in vivo models of the blood-brain barrier have shown that E. coli meningitis follows a high-degree of bacteremia and invasion of the blood-brain barrier. E. coli invasion of the blood-brain barrier, the essentials step in the development of E. coli meningitis, requires specific microbial and host factors as well as microbe- and host-specific signaling molecules. Blockade of such microbial and host factors contributing to E. coli invasion of the blood-brain barrier is shown to be efficient in preventing E. coli penetration into the brain. The basis for requiring a high-degree of bacteremia for E. coli penetration of the blood-brain barrier, however, remains unclear. Continued investigation on the microbial and host factors contributing to a high-degree of bacteremia and E. coli invasion of the blood-brain barrier is likely to identify new targets for prevention and therapy of E. coli meningitis.

  9. Monitoring of Intracranial Pressure in Meningitis.

    Depreitere, Bart; Bruyninckx, Dominike; Güiza, Fabian

    2016-01-01

    The literature on intracranial pressure (ICP) monitoring in meningitis is limited to case reports and a handful of descriptive series. The aim of this study is to investigate relationships among ICP, cerebral perfusion pressure (CPP), and outcome in meningitis and to identify whether ICP affected clinical decisions. Between 1999 and 2011, a total of 17 patients with meningitis underwent ICP monitoring at the University Hospitals Leuven. Charts were reviewed for clinical history, ICP/CPP data, imaging findings, and Glasgow Outcome Scale score. Univariate correlations were computed for outcome and ICP/CPP variables, computed tomography characteristics, and Corticosteroid Randomization After Significant Head Injury outcome model variables. Treatment decisions were assessed regarding whether or not they were based on ICP. At drain placement, Glasgow Coma Scale scores showed a median of 8 (range 3-12). Six of 17 patients had either one or two nonreactive pupils. Significant correlations with outcome were found for the highest documented ICP value (r = -0.70), the number of episodes when CPP meningitis high ICP and low CPP represent secondary insults. The poor condition of the patients illustrates that the level of suspicion for increased ICP in meningitis may not be high enough.

    Stadalnik, R.C.; Goldstein, E.; Hoeprich, P.D.; McGahan, J.P.

    1981-01-01

    The diagnostic utility of pentetate indium trisodium CSF studies, technetium Tc 99m brain scans, and computerized tomographic (CT) scans was evaluated in eight patients in whom coccidioidal meningitis developed following a dust storm in the Central Valley of California. The 111In flow studies and the CT scans demonstrated hydrocephalus in five patients with clinical findings suggesting this complication. Ventriculitis has not previously been diagnosed before death in patients with coccidioidal meningitis; however, it was demonstrated in two patients by the technetium Tc 99m brain scan. The finding that communicating hydrocephalus occurs early in meningitis and interferes with CSF flow into infected basilar regions has important therapeutic implications in that antifungal agents injected into the lumbar subarachnoid space may not reach these regions

  14. Meningitis after cochlear implantation in Mondini malformation.

    Page, E L; Eby, T L

    1997-01-01

    Although the potential for CSF leakage and subsequent meningitis after cochlear implantation in the malformed cochlea has been recognized, this complication has not been previously reported. We report a case of CSF otorhinorrhea and meningitis after minor head trauma developing 2 years after cochlear implantation in a child with Mondini malformation. Leakage of CSF was identified from the cochleostomy around the electrode of the implant, and this leak was sealed with a temporalis fascia and muscle plug. Although this complication appears to be rare, care must be taken to seal the cochleostomy in children with inner ear malformations at the initial surgery, and any episode of meningitis after surgery must be thoroughly investigated to rule out CSF leakage from the labyrinth.

  16. Protection of cortex by overlying meninges tissue during dynamic indentation of the adolescent brain.

    MacManus, David B; Pierrat, Baptiste; Murphy, Jeremiah G; Gilchrist, Michael D

    2017-07-15

    Traumatic brain injury (TBI) has become a recent focus of biomedical research with a growing international effort targeting material characterization of brain tissue and simulations of trauma using computer models of the head and brain to try to elucidate the mechanisms and pathogenesis of TBI. The meninges, a collagenous protective tri-layer, which encloses the entire brain and spinal cord has been largely overlooked in these material characterization studies. This has resulted in a lack of accurate constitutive data for the cranial meninges, particularly under dynamic conditions such as those experienced during head impacts. The work presented here addresses this lack of data by providing for the first time, in situ large deformation material properties of the porcine dura-arachnoid mater composite under dynamic indentation. It is demonstrated that this tissue is substantially stiffer (shear modulus, μ=19.10±8.55kPa) and relaxes at a slower rate (τ 1 =0.034±0.008s, τ 2 =0.336±0.077s) than the underlying brain tissue (μ=6.97±2.26kPa, τ 1 =0.021±0.007s, τ 2 =0.199±0.036s), reducing the magnitudes of stress by 250% and 65% for strains that arise during indentation-type deformations in adolescent brains. We present the first mechanical analysis of the protective capacity of the cranial meninges using in situ micro-indentation techniques. Force-relaxation tests are performed on in situ meninges and cortex tissue, under large strain dynamic micro-indentation. A quasi-linear viscoelastic model is used subsequently, providing time-dependent mechanical properties of these neural tissues under loading conditions comparable to what is experienced in TBI. The reported data highlights the large differences in mechanical properties between these two tissues. Finite element simulations of the indentation experiments are also performed to investigate the protective capacity of the meninges. These simulations show that the meninges protect the underlying brain tissue

  18. Innervation of the human middle meningeal artery

    Edvinsson, L; Gulbenkian, S; Barroso, C P

    1998-01-01

    The majority of nerve fibers in the middle meningeal artery and branching arterioles are sympathetic, storing norepinephrine and neuropeptide Y (NPY). A sparse supply of fibers contain acetylcholinesterase activity and immunoreactivity toward vasoactive intestinal peptide (VIP), peptidine histidine...... methionine (PHM), and calcitonin gene-related peptide (CGRP). Only few substance P and neuropeptide K immunoreactive fibers are noted. Electronmicroscopy shows axons and terminals at the adventitial medial border of the human middle meningeal artery, with a fairly large distance to the smooth muscle cells...

  19. Meningeal involvement in Behcet's disease: MRI

    Guma, A.; Aguilera, C.; Pons, L.; Acebes, J.; Arruga, J.

    1998-01-01

    Behcet's disease is a multisystem disease that involves the central nervous system up to half of cases. Presentation with neurologic symptoms occurs in 5 % of cases and cerebral venous thrombosis is one of its major manifestations. A feature not previously reported is progressive meningeal thickening with involvement of both optic nerves. We report a patient with cerebral venous thrombosis, meningeal thickening and contrast enhancement on MRI. This patient had two other unusual features: positive antineutrophil cytoplasmic antibodies and later development of central diabetes insipidus. (orig.)

  20. Anthrax Meningitis - Report Of An Autopsied Case

    1999-01-01

    Full Text Available Anthrax is a rare cause of hemorrhagic meningitis in man. This report illustrates the characteristic hemorrhagic manifestations in the brain of a patient dying of anthrax meningitis secondary to overwhelming bacteremia. Gross examination of the brain revealed a thick dense subarachnoid hemorrhage with numerous petechial hemorrhages in the cortex. Histologically, meningoencephalitis with vascular necrosis, edema, perivascular cortical hemorrhages and clumps of Gram positive bacilli in the vascular lumen and invading vessel wall were the salient features. The anthrax bacillus was isolated from CSF and brain tissue and further its pathogenecity was confirmed by animal inoculation.

    2014-01-01

    We aimed to provide data on the diagnosis of tuberculous meningitis (TBM) in this largest case series ever reported. The Haydarpasa-1 study involved patients with microbiologically confirmed TBM in Albania, Croatia, Denmark, Egypt, France, Hungary, Iraq, Italy, Macedonia, Romania, Serbia, Slovenia......, Syria and Turkey between 2000 and 2012. A positive culture, PCR or Ehrlich-Ziehl-Neelsen staining (EZNs) from the cerebrospinal fluid (CSF) was mandatory for inclusion of meningitis patients. A total of 506 TBM patients were included. The sensitivities of the tests were as follows: interferon-γ release.......05). Combination of L-J and ACS was superior to using these tests alone (p

  2. Nasopharyngeal glial heterotopia with delayed postoperative meningitis.

    Maeda, Kenichi; Furuno, Kenji; Chong, Pin Fee; Morioka, Takato

    2017-06-22

    A male infant, who underwent radical resection of a large glial heterotopia at the nasopharynx at 8 days, developed delayed postoperative bacterial meningitis at 9 months. Neuroradiological examination clearly demonstrated that meningitis had occurred because of the intracranial and extracranial connections, which were scarcely seen in the perioperative period. A transsphenoidal extension of hypothalamic hamartoma is possible because the connection started from the right optic nerve, running through the transsphenoidal canal in the sphenoid bone and terminating at the recurrent mass in the nasopharyngeal region. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    2008-01-01

    Full text: The total number of tuberculosis cases in the world is increasing, and less common forms of tuberculous meningitis (TBM) with varying imaging manifestations are being encountered more often. We describe anterior interhemispheric variety of TBM, which has not been previously described to the best of our knowledge in the literature. Common imaging findings in these five patients include predominant involvement of the meninges in the anterior interhemispheric fissure with relatively little enhancement of the basal cisterns. Knowledge of uncommon radiological findings is vital in early diagnosis and treatment of this common disease.

  6. Anatomy and imaging of the normal meninges.

    Patel, Neel; Kirmi, Olga

    2009-12-01

    The meninges are an important connective tissue envelope investing the brain. Their function is to provide a protective coating to the brain and also participate in the formation of blood-brain barrier. Understanding their anatomy is fundamental to understanding the location and spread of pathologies in relation to the layers. It also provides an insight into the characteristics of such pathologies when imaging them. This review aims to describe the anatomy of the meninges, and to demonstrate the imaging findings of specific features.

  7. MODERN CLINICAL AND LABORATORY FEATURES OF ENTEROVIRAL MENINGITIS

    O. V. Usacheva

    2014-04-01

    Full Text Available Among numerous viral meningitises from 80% to 90% of cases are accounted for meningitis of enteroviral etiology according to the international data. Despite the favorable disease course, there are forms which are characterized by severe damage of CNS. In order to improve diagnostics of enteroviral meningitis in this article we have made a comparative analysis of clinical and laboratory parameters in 23 patients with enteroviral meningitis and 18 patients with serous meningitis of non-enteroviral etiology. Anamnesis data and the major clinical manifestations of the disease dynamics were analyzed. Particular attention is paid to the comparison of diagnoses, by which patients were sent to infectious hospital, the symptoms that occurred during patients’ admission into hospitals and their severity. The presence and severity of meningeal symptoms and the indices of cerebrospinal fluid in the patients of the comparison group were analyzed in detail. It is shown that enteroviruses are the important factor in the development of meningitis in the children of younger age. The clinical picture of enteroviral meningitis often develops gradually for 2-3 days and includes the typical syndromes: intoxication and meningeal ones. Every third patient with enterovirus infection has diarrhea and catarrhal symptoms, that’s why it is difficult to diagnose meningitis in its early stages, but it allows to assume enteroviral etiology of the disease. The meningitis of enteroviral etiology is characterized by multiple meningeal signs, while the non-enteroviral meningitis is characterized by dissociation with the prevalence of the of Kernig’s and Brudzinski’s symptoms. The analysis of the laboratory data showed that the enteroviral meningitis is characterized by low (over 50-100 cells "mixed" pleocytosis (the ratio of lymphocytes and neutrophils is about 1:1. These data can be used for differential diagnosis between enteroviral meningitis and serous meningitis of

    Schoerner, W.; Henkes, H.; Sander, B.; Felix, R.

    1988-01-01

    The MR appearance of normal and pathological meninges was studied in 23 patients. Amongst twelve normals, T 1 -weighted images demonstrated the meninges as slightly hyperintense density structures (compared with CSF) which increased in signal intensity somewhat after the administration of gadolinium-DTPA. On T 2 -weighted images, the subarachnoid space and meninges were isointense. In eleven patients with inflammatory disease or tumourous infiltration of the meninges, abnormal findings were evident in the unenhanced images as well as after administration of gadolinium-DTPA. Compared with CT, MR proved greatly superior in the diagnosis of meningeal abnormalities. (orig.) [de

    2001-03-01

    Full Text Available Introduction. Central nervous system infections are among the most serious conditions in of medical practice. C-reactive Protein has recently been evaluated in terms of its ability to diffeccentiate bacterial from nonbacterial central nervous system inflammations.
    Methods. We studied the frequency of positive CRP in 61 patients who had signs of meningitis. All the specimens referred to one laboratory and were examined by Slide method.
    Results. Positive CRP was found in 97.6 percent of those who were finally diagnosed as bacterial meningitis. The frequency of CRP for other types of meningitis was 16.6 percent (P < 0.05.
    Discussion. In the absence of infection, CSF is free of CRP. Positive CRP may help to the differentiate the different types of meningitis.

    ABSTRACT: BACKGROUND: Bacteremia and systemic complications both play important roles in brain pathophysiological alterations and the outcome of pneumococcal meningitis. Their individual contributions to the development of brain damage, however, still remain to be defined. METHODS: Using an adult...... rat pneumococcal meningitis model, the impact of bacteremia accompanying meningitis on the development of hippocampal injury was studied. The study comprised of the three groups: I. Meningitis (n=11), II. meningitis with attenuated bacteremia resulting from iv injection of serotype......-specific pneumococcal antibodies (n=14), and III. uninfected controls (n=6). RESULTS: Pneumococcal meningitis resulted in a significantly higher apoptosis score 0.22 (0.18-0.35) compared to uninfected controls (0.02 (0.00-0.02), Mann Whitney test, P=0.0003). Also, meningitis with an attenuation of bacteremia...

    Highlights: • Purpose of this review is to address the current concepts on the pathophysiology of discogenic, radicular, facet and dysfunctional spinal pain, focusing on the role of the imaging in the diagnostic setting, to potentially address a correct approach also to minimally invasive interventional techniques. • Special attention will be given to the discogenic pain, actually considered as the most frequent cause of chronic low back pain. • The correct distinction between referred pain and radicular pain contributes to give a more correct approach to spinal pain. • The pathogenesis of chronic pain renders this pain a true pathology requiring a specific management. - Abstract: The spinal pain, and expecially the low back pain (LBP), represents the second cause for a medical consultation in primary care setting and a leading cause of disability worldwide [1]. LBP is more often idiopathic. It has as most frequent cause the internal disc disruption (IDD) and is referred to as discogenic pain. IDD refers to annular fissures, disc collapse and mechanical failure, with no significant modification of external disc shape, with or without endplates changes. IDD is described as a separate clinical entity in respect to disc herniation, segmental instability and degenerative disc desease (DDD). The radicular pain has as most frequent causes a disc herniation and a canal stenosis. Both discogenic and radicular pain also have either a mechanical and an inflammatory genesis. For to be richly innervated, facet joints can be a direct source of pain, while for their degenerative changes cause compression of nerve roots in lateral recesses and in the neural foramina. Degenerative instability is a common and often misdiagnosed cause of axial and radicular pain, being also a frequent indication for surgery.

  14. Meningeal infiltration in recurrent nasopharyngeal carcinoma

    Chong, V.F.H.; Fan, Y.-F.

    2000-01-01

    Permeative infiltration of the meninges appears to be a distinct form of recurrent nasopharyngeal carcinoma (NPC). The present report of eight patients with recurrent NPC illustrates meningeal infiltration following basal foramina extension. Seven of the eight patients (88%) showed jugular foramen involvement. Three patients had concomitant infiltration of the foramen magnum. There was one patient showing spread through the foramen lacerum. Only four (50%) of these patients had clinically detectable tumour in the nasopharynx, while the other half showed deep submucosal recurrence with endoscopically unremarkable findings. Permeative meningeal infiltration appears to be a distinct form of NPC recurrence. It is important to recognize this phenomenon so as to optimize the treatment options. The imaging studies were reviewed and the following features were recorded: local nasopharyngeal recurrence, the manner of intracranial spread and site of meningeal infiltration. Four patients had only MRI, two had only CT and two patients had both CT and MRI. The presence or absence of intracranial tumour before treatment was also recorded. Two observers reviewed the images and results were arrived at by consensus. Copyright (1999) Blackwell Science Pty Ltd

    Hutzelmann, A.; Palmie, S.; Zimmer, C.; Benz, T.; Leweke, F.; Freund, M.

    1996-01-01

    To evaluate the occurrence of the meningeal sign in meningiomas and metastases. We studied 20 patients with meningiomas and 17 patients with cerebral metastases adjacent to the dura. MRI studies (Siemens, Magnetom 1,5) included axial T 1 -weighted and T 2 -weighted unenhanced as well as gadolinium-DTPA enhanced T 1 -weighted (axial, coronal, sagittal) SE imaging. In all patients the tumours were resected with the attached dura mater. Histopathological examinations were done, which corresponded to the area of marked enhancement by gadolinium-DTPA. There was no correlation between the occurrence of the meningeal sign and the histopathological examinations. In 20 patients with meningiomas adjacent to the dura we found the meningeal sign in 11 cases. Histologically we observed an increase of collagen fibres and fibrocytes. In 5 to 17 cases with superficial cerebral as dura infiltrations and microbleedings. The meningeal sign is not specific for meningiomas and can be observed in a wide variety of pathological entities.

Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

  19. Cryptococcal meningitis: epidemiology, immunology, diagnosis and therapy.

    HIV-associated cryptococcal meningitis is by far the most common cause of adult meningitis in many areas of the world that have high HIV seroprevalence. In most areas in Sub-Saharan Africa, the incidence of cryptococcal meningitis is not decreasing despite availability of antiretroviral therapy, because of issues of adherence and retention in HIV care. In addition, cryptococcal meningitis in HIV-seronegative individuals is a substantial problem: the risk of cryptococcal infection is increased in transplant recipients and other individuals with defects in cell-mediated immunity, and cryptococcosis is also reported in the apparently immunocompetent. Despite therapy, mortality rates in these groups are high. Over the past 5 years, advances have been made in rapid point-of-care diagnosis and early detection of cryptococcal antigen in the blood. These advances have enabled development of screening and pre-emptive treatment strategies aimed at preventing the development of clinical infection in patients with late-stage HIV infection. Progress in optimizing antifungal combinations has been aided by evaluation of the clearance rate of infection by using serial quantitative cultures of cerebrospinal fluid (CSF). Measurement and management of raised CSF pressure, a common complication, is a vital component of care. In addition, we now better understand protective immune responses in HIV-associated cases, immunogenetic predisposition to infection, and the role of immune-mediated pathology in patients with non-HIV associated infection and in the context of HIV-associated immune reconstitution reactions.

  20. Bilateral optic neuropathy in acute cryptococcal meningitis

    Qi Zhe Ngoo; Li Min Evelyn Tai; Wan Hazabbah Wan Hitam; John Tharakan

    2016-01-01

    We reported a case of cryptococcal meningitis presenting with bilateral optic neuropathy in an immunocompetent patient. A 64-year-old Malay gentleman with no medical comorbidities presented with acute bilateral blurring of vision for a week, which was associated with generalised throbbing headache and low grade fever. He also had som-nolence and altered consciousness. Visual acuity in both eyes was no perception of light with poor pupillary reflexes. Extraocular muscle movements were normal. Anterior segments were unremarkable bilaterally. Fundoscopy revealed bilateral optic disc swelling. CT scan of the brain showed multifocal infarct, but no meningeal enhancement or mass. Cerebrospinal fluid opening pressure was normal, while its culture grew Cryptococcus neoformans. A diagnosis of cryptococcal meningitis with bilateral optic neuropathy was made. Patient was treated with a six-week course of intravenous flu-conazole and started concomitantly on a fortnight's course of intravenous amphotericin B. After that, his general condition improved, but there was still no improvement in his visual acuity. On reviewing at two months post-initiation of treatment, fundi showed bilateral optic atrophy. Bilateral optic neuropathy secondary to cryptococcal meningitis was rare. The prognosis was guarded due to the sequelae of optic atrophy. Anti-fungal medication alone may not be sufficient to manage this condition. However, evidence for other treatment modalities is still lacking and further clinical studies are required.

  4. Pathogenesis and Pathophysiology of Pneumococcal Meningitis

    Mook-Kanamori, Barry B.; Geldhoff, Madelijn; van der Poll, Tom; van de Beek, Diederik

    2011-01-01

    Summary: Pneumococcal meningitis continues to be associated with high rates of mortality and long-term neurological sequelae. The most common route of infection starts by nasopharyngeal colonization by Streptococcus pneumoniae, which must avoid mucosal entrapment and evade the host immune system after local activation. During invasive disease, pneumococcal epithelial adhesion is followed by bloodstream invasion and activation of the complement and coagulation systems. The release of inflammatory mediators facilitates pneumococcal crossing of the blood-brain barrier into the brain, where the bacteria multiply freely and trigger activation of circulating antigen-presenting cells and resident microglial cells. The resulting massive inflammation leads to further neutrophil recruitment and inflammation, resulting in the well-known features of bacterial meningitis, including cerebrospinal fluid pleocytosis, cochlear damage, cerebral edema, hydrocephalus, and cerebrovascular complications. Experimental animal models continue to further our understanding of the pathophysiology of pneumococcal meningitis and provide the platform for the development of new adjuvant treatments and antimicrobial therapy. This review discusses the most recent views on the pathophysiology of pneumococcal meningitis, as well as potential targets for (adjunctive) therapy. PMID:21734248

    Bacterial meningitis kills or maims about a fifth of people with the disease. Early antibiotic treatment improves outcomes, but the effectiveness of widely available antibiotics is threatened by global emergence of multidrug-resistant bacteria. New antibiotics, such as fluoroquinolones, could have a

    Objective: To evaluate the relationship of clinical and magnetic resonance imaging (MRI) findings in patients with tuberculous meningitis (TBM), and to improve the understanding of TBM. Methods: The clinical and MRI findings in 42 patients with confirmed TBM were analyzed retrospectively. MRI examination was performed using a 1 Tesla system, including SE T 1 WI and T 2 WI. Intravenous contrast was injected in 29 patients, and follow-up scans were performed on 17 patients. Results: Of 24 patients with early TBM, MRI was abnormal in 5(21%) with slight Tl-hypointense meningeal (4) or ependymal thickening (1). MRI on 33/35 (94%) patients with late stage TBM was abnormal with T 1 hypointensity and T 2 hyperintensity including meningeal thickening (19), mild surrounding brain edema (10), nodules (11), tuberculoma (5) and abscess (2). There was significant plaque-like, nodular or rim enhancement with surrounding brain edema. Conclusion: Tuberculous meningitis has minimal clinical and MRI findings in the early phase and significant clinical and MRI findings in the late phase. The enhanced scan may help to detect the abnormality. (authors)

  12. Meninges: from protective membrane to stem cell niche.

    Decimo, Ilaria; Fumagalli, Guido; Berton, Valeria; Krampera, Mauro; Bifari, Francesco

    2012-01-01

    Meninges are a three tissue membrane primarily known as coverings of the brain. More in depth studies on meningeal function and ultrastructure have recently changed the view of meninges as a merely protective membrane. Accurate evaluation of the anatomical distribution in the CNS reveals that meninges largely penetrate inside the neural tissue. Meninges enter the CNS by projecting between structures, in the stroma of choroid plexus and form the perivascular space (Virchow-Robin) of every parenchymal vessel. Thus, meninges may modulate most of the physiological and pathological events of the CNS throughout the life. Meninges are present since the very early embryonic stages of cortical development and appear to be necessary for normal corticogenesis and brain structures formation. In adulthood meninges contribute to neural tissue homeostasis by secreting several trophic factors including FGF2 and SDF-1. Recently, for the first time, we have identified the presence of a stem cell population with neural differentiation potential in meninges. In addition, we and other groups have further described the presence in meninges of injury responsive neural precursors. In this review we will give a comprehensive view of meninges and their multiple roles in the context of a functional network with the neural tissue. We will highlight the current literature on the developmental feature of meninges and their role in cortical development. Moreover, we will elucidate the anatomical distribution of the meninges and their trophic properties in adult CNS. Finally, we will emphasize recent evidences suggesting the potential role of meninges as stem cell niche harbouring endogenous precursors that can be activated by injury and are able to contribute to CNS parenchymal reaction.

  13. Spinal stenosis

    Beale, S.; Pathria, M.N.; Ross, J.S.; Masaryk, T.J.; Modic, M.T.

    1988-01-01

    The authors studied 50 patients who had spinal stenosis by means of MR imaging. All patients had undergone myelography and CT. Thirty patients underwent surgery. MR imaging included T1-weighted spin echo sequences with repetition time = 600 msec, echo time = 20 (600/20) sagittal and axial sections 4 mm thick with 2 mm gap. T2-weighted 2,000/60 axial images were obtained on 14 patients. Examinations were retrospectively evaluated for central stenosis, lateral recess narrowing, and foraminal encroachment. Measurements of sagittal, interpedicular, interfacet, and recess dimensions were made at L3-5. On MR images, 20 patients had single-level and 30 had multiple-level stenosis. There was excellent agreement between modalities with central canal stenosis, but a discrepancy in six patients with bony foraminal stenosis. MR imaging was an accurate method for assessment of lumbar stenosis, but CT appears marginally better for detection of bony foraminal stenosis in certain cases

    2012-03-01

    Full Text Available Abstract Background S. pneumoniae is the most common causative agent of meningitis, and is associated with high morbidity and mortality. We aimed to develop an integrated and representative pneumococcal meningitis mouse model resembling the human situation. Methods Adult mice (C57BL/6 were inoculated in the cisterna magna with increasing doses of S. pneumoniae serotype 3 colony forming units (CFU; n = 24, 104, 105, 106 and 107 CFU and survival studies were performed. Cerebrospinal fluid (CSF, brain, blood, spleen, and lungs were collected. Subsequently, mice were inoculated with 104 CFU S. pneumoniae serotype 3 and sacrificed at 6 (n = 6 and 30 hours (n = 6. Outcome parameters were bacterial outgrowth, clinical score, and cytokine and chemokine levels (using Luminex® in CSF, blood and brain. Meningeal inflammation, neutrophil infiltration, parenchymal and subarachnoidal hemorrhages, microglial activation and hippocampal apoptosis were assessed in histopathological studies. Results Lower doses of bacteria delayed onset of illness and time of death (median survival CFU 104, 56 hrs; 105, 38 hrs, 106, 28 hrs. 107, 24 hrs. Bacterial titers in brain and CSF were similar in all mice at the end-stage of disease independent of inoculation dose, though bacterial outgrowth in the systemic compartment was less at lower inoculation doses. At 30 hours after inoculation with 104 CFU of S. pneumoniae, blood levels of KC, IL6, MIP-2 and IFN- γ were elevated, as were brain homogenate levels of KC, MIP-2, IL-6, IL-1β and RANTES. Brain histology uniformly showed meningeal inflammation at 6 hours, and, neutrophil infiltration, microglial activation, and hippocampal apoptosis at 30 hours. Parenchymal and subarachnoidal and cortical hemorrhages were seen in 5 of 6 and 3 of 6 mice at 6 and 30 hours, respectively. Conclusion We have developed and validated a murine model of pneumococcal meningitis.

  15. Brain and spinal cord neoplasms

    Anderson, R.E.; Bragg, D.G.; Youker, J.E.

    1985-01-01

    Traditional means of detecting CNS neoplasms include plain film studies, isotope brain scans, angiography, pneumoencephalography, and myelography. Computed tomography (CT) scanning has replaced nearly all of these studies in both the initial detection and follow-up of brain tumors. Air studies (pneumoencephalography and ventriculography) have been virtually eliminated, except in certain unusual circumstances when two positions need to be checked, or hydrocephalus followed. The nuclear brain scan has a very limited role at present, being useful primarily for detecting skull or meningeal metastases. Myelography, however, remains a valuable imaging tool for the assessment of tumors of the spinal canal. CT scanning has not only improved our ability to detect smaller brain tumors, but also CT guided stereotactic biopsy techniques provide a safer means of obtaining tissue from these smaller lesions, regardless of location. Surgical techniques, guided by CT sterotactic techniques, show promise as well, but the impact of these therapeutic techniques on survival statistics remains to be defined. CT has revolutionized the approach to the detection and diagnosis of space-occupying lesions in the brain. Tumors can be detected at a smaller site

  17. MRI of primary meningeal tumours in children

    Yoon, H.K.; Na, D.G.; Byun, H.S.; Han, B.K.; Kim, S.S.; Kim, I.O.; Shin, H.J.

    1999-01-01

    Childhood meningeal tumours are uncommon and mostly meningiomas. We reviewed the histological and radiological findings in meningeal tumours in six children aged 12 years or less (four benign meningiomas, one malignant meningioma and one haemangiopericytoma). Compared to the adult counterpart, childhood meningiomas showed atypical features: cysts, haemorrhage, aggressiveness and unusual location. MRI features varied according to the site of the tumour, histology, haemorrhage, and presence of intra- or peritumoral cysts. Diagnosis of the extra-axial tumour was relatively easy in two patients with meningiomas, one malignant meningioma and one haemangiopericytoma. MRI findings strongly suggested an intra-axial tumour in two patients with benign meningiomas, because of severe adjacent edema. Awareness of the variable findings of childhood meningiomas and similar tumours may help in differentiation from brain tumours. (orig.)

  18. Mumps vaccine virus strains and aseptic meningitis.

    Bonnet, Marie-Claude; Dutta, Anil; Weinberger, Clement; Plotkin, Stanley A

    2006-11-30

    Mumps immunization can easily be included in national schedules, particularly if combined with measles or measles and rubella vaccines, but debate continues concerning the relative safety of various licensed mumps vaccine strains. The opportunities for control of mumps are also being affected by differences in the cost of the vaccines prepared with different strains of mumps virus. The present report evaluates available data on the association of the Urabe and other strains of mumps vaccine with the occurrence of aseptic meningitis. We also review the comparative immunogenicity and efficacies of the most widely used mumps vaccines in controlled clinical trials and field evaluations, and briefly examine relative cost as it relates to the implementation of national immunization programs. We conclude that extensive experience with the most widely used mumps vaccine strains in many countries has shown that the risk-benefit ratio of live mumps vaccines is highly favourable for vaccination, despite the occasional occurence of aseptic meningitis.

  15. Transethmoidal intranasal meningoencephalocele in an adult with recurrent meningitis.

    Hasegawa, Takafumi; Sugeno, Naoto; Shiga, Yusei; Takeda, Atsushi; Karibe, Hiroshi; Tominaga, Teiji; Itoyama, Yasuto

    2005-08-01

    Intranasal meningoencephalocele is a rarely encountered congenital malformation. We report a case of transethmoidal intranasal meningoencephalocele in a 52-year old man with recurrent purulent meningitis. After treatment of the acute meningitis, frontal craniotomy followed by the removal of the stalk of the meningoencephalocele and repair of the bony defect was successfully performed. He has had no further meningitis or CSF rhinorrhea post-operatively. Detailed neuroradiological examination and appropriate surgical treatment are important to prevent fatal neurological complications of intranasal meningoencephalocele.

  16. Isolated Meningeal Recurrence of Transitional Cell Carcinoma of the Bladder

    Catherine Butchart

    2010-06-01

    Full Text Available Meningeal carcinomatosis occurs in 1–18% of patients with solid tumours, most commonly carcinomas of the breast and lung or melanomas. There are relatively few reports of meningeal carcinomatosis in transitional cell carcinoma of the bladder. Isolated meningeal recurrence is particularly uncommon, and we present an unusual case of this in a 58-year-old man. The case was further complicated by the somewhat atypical presentation with a confirmed ischaemic stroke. The patient died one month after presentation.

  18. Congenital malformations of the skull and meninges.

    Kanev, Paul M

    2007-02-01

    The surgery and management of children who have congenital malformations of the skull and meninges require multidisciplinary care and long-term follow-up by multiple specialists in birth defects. The high definition of three-dimensional CT and MRI allows precise surgery planning of reconstruction and management of associated malformations. The reconstruction of meningoencephaloceles and craniosynostosis are challenging procedures that transform the child's appearance. The embryology, clinical presentation, and surgical management of these malformations are reviewed.

  19. The Role of Vancomycin on Meningitis

    Ahmed I. Shatat and P.I.C.U team

    2014-06-01

    Conclusion: After the previous discussion of the results obtained from this study, the researchers concluded that most of the cases diagnosed meningitis was aseptic and there was no need for antibiotics. Also in those who diagnosed as bacterial vancomycin was not essential in all cases, this confirmed by the absence of any differences in the outcome. [Cukurova Med J 2014; 39(3.000: 501-511

  1. Spinal segmental dysgenesis

    N Mahomed

    2009-06-01

    Full Text Available Spinal segmental dysgenesis is a rare congenital spinal abnormality , seen in neonates and infants in which a segment of the spine and spinal cord fails to develop normally . The condition is segmental with normal vertebrae above and below the malformation. This condition is commonly associated with various abnormalities that affect the heart, genitourinary, gastrointestinal tract and skeletal system. We report two cases of spinal segmental dysgenesis and the associated abnormalities.

  2. A 51-year-old man with intramedullary spinal cord abscess having a patent foramen ovale

    Higuchi, Kanako; Ishihara, Hiroyuki; Okuda, Shiho; Kanda, Fumio

    2011-01-01

    The authors report a case of a 51-year-old man with intramedullary spinal cord abscess (ISCA) having a patent foramen ovale (PFO). He developed fever and tetraplegia after a recent dental treatment. MRI showed ISCA with longitudinal swelling from the upper cervical to the lumbar spinal cord. Cerebrospinal fluid (CSF) analysis indicated bacterial meningitis, and the culture of CSF revealed Streptococcus viridans. Transoesophageal echocardiography revealed the existence of a PFO. We suspected another possibility other than systemic bacteraemia, that paradoxical bacteric embolisation through PFO after the dental treatment caused ISCA. While several reports of brain abscess with PFO are available, this is the first report of ISCA with PFO. PMID:22696715

  3. Gd-DTPA-enhanced MR imaging in meningitis

    Han, M.H.; Chang, K.H.; Roh, J.K.; Kim, I.O.; Han, M.C.; Kim, C.W.

    1988-01-01

    Gd-DPTA-enhanced MR imaging was performed in 16 patients with meningitis (seven tuberculous, four bacterial, three fungal, and two viral) on a 2.0-T unit. Hemorrhagic infarcts of basal ganglia and localized enhancement of thickened dura adjacent were demonstrated on T1-weighted images in three patients with tuberculous meningitis and four with bacterial meningitis, respectively, that were not seen on CT. Enhanced T1-weighted images readily differentiated leptomeningeal enhancement from vessels in two cases with CT of equivocal meningeal enhancement. Nonenhanced T2-weighted images were most sensitive for demonstrating ischemia/infarct and edema. Otherwise, MR images generally matched CT scans

  4. Postoperative meningeal enhancement on MRI in children with brain neoplasms

    Lee, Min Hee; Han, Bokyung Kim; Yoon, Hye Kyung; Shin, Hyung Jin

    2000-01-01

    The meninges composed of the dura, the arachnoid and the pia are significant sites of blood-brain barrier. Physical disruption of the integrity of the meninges from a variety of causes including surgery results in various patterns of meningeal enhancement on contrast enhanced MR images. It is important to distinguish normal reactive or benign postoperative enhancement from more serious leptomeningeal metastasis or infection, particularly in children with intracranial neoplasms. We present various patterns of meningeal enhancement on MRI in children following surgery for brain neoplasms. (author)

  5. Pneumococcal meningitis post-cochlear implantation: preventative measures.

    Wei, Benjamin P C; Shepherd, Robert K; Robins-Browne, Roy M; Clark, Graeme M; O'Leary, Stephen J

    2010-11-01

    Both clinical data and laboratory studies demonstrated the risk of pneumococcal meningitis post-cochlear implantation. This review examines strategies to prevent post-implant meningitis. Medline/PubMed database; English articles after 1980. Search terms: cochlear implants, pneumococcus meningitis, streptococcus pneumonia, immunization, prevention. Narrative review. All articles relating to post-implant meningitis without any restriction in study designs were assessed and information extracted. The presence of inner ear trauma as a result of surgical technique or cochlear implant electrode array design was associated with a higher risk of post-implant meningitis. Laboratory data demonstrated the effectiveness of pneumococcal vaccination in preventing meningitis induced via the hematogenous route of infection. Fibrous sealing around the electrode array at the cochleostomy site, and the use of antibiotic-coated electrode array reduced the risk of meningitis induced via an otogenic route. The recent scientific data support the U.S. Food and Drug Administration recommendation of pneumococcal vaccination for the prevention of meningitis in implant recipients. Nontraumatic cochlear implant design, surgical technique, and an adequate fibrous seal around the cochleostomy site further reduce the risk of meningitis.

    Spontaneous,non-surgical haematogenous Staphylococcus aureus meningitis is rare and associated with high mortality.Mixed infection causing meningitis (pyogenic and tubercular)is further rarer,poses a difficult diag-nostic and management challenge,which warrants early diagnosis and aggressive therapy.We present a case of concurrent pyogenic and tubercular meningitis in a child managed successfully.It seems that in present case initial pyogenic infection resulted in the immunocompromised state for the child that would had lead to the acti-vation of tubercular foci resulting in tubercular meningitis.

  7. Incidental finding of cutaneous meningeal heterotopia in aplasia cutis congenita.

    Kenyon, Katharine; Zedek, Daniel; Sayed, Christopher

    2016-07-01

    Aplasia cutis congenita and cutaneous meningeal heterotopia are both rare congenital conditions that most commonly occur on the scalp and may appear clinically and histologically similar. A subtype of aplasia cutis congenita, membranous aplasia cutis congenita, and cutaneous meningeal heterotopia are both proposed to result from neural tube closure errors. However, neither non-membranous nor membranous aplasia cutis congenita are known to occur together with cutaneous meningeal heterotopia in the same lesion. We report the incidental finding of cutaneous meningeal heterotopia within a lesion of aplasia cutis congenita. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  8. Sub-meninges implantation reduces immune response to neural implants.

    Markwardt, Neil T; Stokol, Jodi; Rennaker, Robert L

    2013-04-15

    Glial scar formation around neural interfaces inhibits their ability to acquire usable signals from the surrounding neurons. To improve neural recording performance, the inflammatory response and glial scarring must be minimized. Previous work has indicated that meningeally derived cells participate in the immune response, and it is possible that the meninges may grow down around the shank of a neural implant, contributing to the formation of the glial scar. This study examines whether the glial scar can be reduced by placing a neural probe completely below the meninges. Rats were implanted with sets of loose microwire implants placed either completely below the meninges or implanted conventionally with the upper end penetrating the meninges, but not attached to the skull. Histological analysis was performed 4 weeks following surgical implantation to evaluate the glial scar. Our results found that sub-meninges implants showed an average reduction in reactive astrocyte activity of 63% compared to trans-meninges implants. Microglial activity was also reduced for sub-meninges implants. These results suggest that techniques that isolate implants from the meninges offer the potential to reduce the encapsulation response which should improve chronic recording quality and stability.

  13. From Epidemic Meningitis Vaccines for Africa to the Meningitis Vaccine Project.

    Aguado, M Teresa; Jodar, Luis; Granoff, Dan; Rabinovich, Regina; Ceccarini, Costante; Perkin, Gordon W

    2015-11-15

    Polysaccharide vaccines had been used to control African meningitis epidemics for >30 years but with little or modest success, largely because of logistical problems in the implementation of reactive vaccination campaigns that are begun after epidemics are under way. After the major group A meningococcal meningitis epidemics in 1996-1997 (250,000 cases and 25,000 deaths), African ministers of health declared the prevention of meningitis a high priority and asked the World Health Organization (WHO) for help in developing better immunization strategies to eliminate meningitis epidemics in Africa. WHO accepted the challenge and created a project called Epidemic Meningitis Vaccines for Africa (EVA) that served as an organizational framework for external consultants, PATH, the US Centers for Disease Control and Prevention (CDC), and the Bill & Melinda Gates Foundation (BMGF). Consultations were initiated with major vaccine manufacturers. EVA commissioned a costing study/business plan for the development of new group A or A/C conjugate vaccines and explored the feasibility of developing these products as a public-private partnership. Representatives from African countries were consulted. They confirmed that the development of conjugate vaccines was a priority and provided information on preferred product characteristics. In parallel, a strategy for successful introduction was also anticipated and discussed. The expert consultations recommended that a group A meningococcal conjugate vaccine be developed and introduced into the African meningitis belt. The results of the costing study indicated that the "cost of goods" to develop a group A - containing conjugate vaccine in the United States would be in the range of US$0.35-$1.35 per dose, depending on composition (A vs A/C), number of doses/vials, and presentation. Following an invitation from BMGF, a proposal was submitted in the spring of 2001. In June 2001, BMGF awarded a grant of US$70 million to create the Meningitis

  14. Patterns of contrast enhancement in the brain and meninges.

    Smirniotopoulos, James G; Murphy, Frances M; Rushing, Elizabeth J; Rees, John H; Schroeder, Jason W

    2007-01-01

    Contrast material enhancement for cross-sectional imaging has been used since the mid 1970s for computed tomography and the mid 1980s for magnetic resonance imaging. Knowledge of the patterns and mechanisms of contrast enhancement facilitate radiologic differential diagnosis. Brain and spinal cord enhancement is related to both intravascular and extravascular contrast material. Extraaxial enhancing lesions include primary neoplasms (meningioma), granulomatous disease (sarcoid), and metastases (which often manifest as mass lesions). Linear pachymeningeal (dura-arachnoid) enhancement occurs after surgery and with spontaneous intracranial hypotension. Leptomeningeal (pia-arachnoid) enhancement is present in meningitis and meningoencephalitis. Superficial gyral enhancement is seen after reperfusion in cerebral ischemia, during the healing phase of cerebral infarction, and with encephalitis. Nodular subcortical lesions are typical for hematogenous dissemination and may be neoplastic (metastases) or infectious (septic emboli). Deeper lesions may form rings or affect the ventricular margins. Ring enhancement that is smooth and thin is typical of an organizing abscess, whereas thick irregular rings suggest a necrotic neoplasm. Some low-grade neoplasms are "fluid-secreting," and they may form heterogeneously enhancing lesions with an incomplete ring sign as well as the classic "cyst-with-nodule" morphology. Demyelinating lesions, including both classic multiple sclerosis and tumefactive demyelination, may also create an open ring or incomplete ring sign. Thick and irregular periventricular enhancement is typical for primary central nervous system lymphoma. Thin enhancement of the ventricular margin occurs with infectious ependymitis. Understanding the classic patterns of lesion enhancement--and the radiologic-pathologic mechanisms that produce them--can improve image assessment and differential diagnosis.

  15. Trauma: Spinal Cord Injury.

    Eckert, Matthew J; Martin, Matthew J

    2017-10-01

    Injuries to the spinal column and spinal cord frequently occur after high-energy mechanisms of injury, or with lower-energy mechanisms, in select patient populations like the elderly. A focused yet complete neurologic examination during the initial evaluation will guide subsequent diagnostic procedures and early supportive measures to help prevent further injury. For patients with injury to bone and/or ligaments, the initial focus should be spinal immobilization and prevention of inducing injury to the spinal cord. Spinal cord injury is associated with numerous life-threatening complications during the acute and long-term phases of care that all acute care surgeons must recognize. Published by Elsevier Inc.

    Nielsen, Jens Bo

    2016-01-01

    Human studies in the past three decades have provided us with an emerging understanding of how cortical and spinal networks collaborate to ensure the vast repertoire of human behaviors. We differ from other animals in having direct cortical connections to spinal motoneurons, which bypass spinal...... the central motor command by opening or closing sensory feedback pathways. In the future, human studies of spinal motor control, in close collaboration with animal studies on the molecular biology of the spinal cord, will continue to document the neural basis for human behavior.

  17. The meninges is a source of retinoic acid for the late-developing hindbrain.

    Zhang, Jinghua; Smith, Deborah; Yamamoto, Miyuki; Ma, Lanhua; McCaffery, Peter

    2003-08-20

    One general function for retinoic acid (RA) is pattern organization in the CNS. This regulatory factor has an essential role in spinal cord motor neuron and early posterior hindbrain development. In the anterior CNS, however, there is only a limited number of foci of RA synthesis, and less attention has been placed on regions such as the anterior hindbrain where RA synthesizing enzymes are absent. This study shows that a rich source of RA lies around the hindbrain from the RA synthetic enzyme retinaldehyde dehydrogenase-2 (RALDH2) present in the surrounding meninges and mesenchyme by embryonic day 13. RALDH2 is not distributed uniformly throughout the meninges but is restricted to territories over the developing hindbrain, suggesting that RA signaling may be localized to those regions. Further regulation of RA signaling is provided by the presence of a RA sink in the form of the CYP26B1 RA catabolic enzyme expressed in deeper regions of the brain. As a guide to the neural anatomy of hindbrain RA signaling, we used a mouse transgenic for a lacZ reporter gene driven by a RA response element (RAREhsplacZ) to identify regions of RA signaling. This reporter mouse provides evidence that RA signaling in the hindbrain after embryonic day 13 occurs in the regions of the cerebellum and precerebellar system adjacent to sources of RA, including the inferior olive and the pontine nuclei.

  18. Ehrlichia Meningitis Mimicking Aneurysmal Subarachnoid Hemorrhage: A Case Study for Medical Decision-Making Heuristics.

    Dredla, Brynn; Freeman, William D

    2016-04-01

    Thunderclap headache is a sudden and severe headache that can occur after an aneurysmal subarachnoid hemorrhage (SAH). Subarachnoid hemorrhage is a medical emergency that requires prompt attention and hospitalization. Patients with thunderclap headache often undergo a noncontrast head computed tomography (CT) scan to ascertain SAH bleeding and, if the scan is negative, then undergo a lumbar puncture to look for cerebrospinal fluid (CSF) red blood cells (RBCs), which would be consistent with an aneurysmal leak. If the initial CT is negative and CSF is positive for RBCs, patients are usually admitted to the hospital for evaluation of intracranial aneurysm. We encountered a patient with thunderclap headache whose initial head CT was negative for SAH and whose CSF tested positive for RBCs. The patient was referred to our center for evaluation and management of aneurysmal SAH. However, on careful review of the patient's medical history, serum laboratory values, and spinal fluid values, the patient was diagnosed with Ehrlichia chaffeensis meningitis. While Ehrlichia meningitis is rare, it is important to recognize the clinical clues that could help avoid formal cerebral angiography, a costly and potentially unnecessary procedure. We present how this case represented a cognitive framing bias and anchoring heuristic as well as steps that medical providers can use to prevent such cognitive errors in diagnosis.

  19. Mast cell inflammasome activity in the meninges regulates EAE disease severity.

    Russi, Abigail E; Walker-Caulfield, Margaret E; Brown, Melissa A

    2018-04-01

    Inflammasomes are multiprotein complexes that assemble in response to microbial and other danger signals and regulate the secretion of biologically active IL-1β and IL-18. Although they are important in protective immunity against bacterial, viral and parasitic infections, aberrant inflammasome activity promotes chronic inflammation associated with autoimmune disease. Inflammasomes have been described in many immune cells, but the majority of studies have focused on their activity in macrophages. Here we discuss an important role for mast cell-inflammasome activity in EAE, the rodent model of multiple sclerosis, a CNS demyelinating disease. We review our evidence that mast cells in the meninges, tissues that surround the brain and spinal cord, interact with infiltrating myelin-specific T cells in early disease. This interaction elicits IL-1β expression by mast cells, which in turn, promotes GM-CSF expression by T cells. In view of the essential role that GM-CSF plays in T cell encephalitogenicity, we propose this mast cell-T cell crosstalk in the meninges is critical for EAE disease development.

  20. A novel fibrous duct structure discovered in the brain meninges by using polarized light microscopy

    Nam, Min-Ho; Jung, Sharon Jiyoon; Soh, Kwang-Sup; Lim, Jaekwan; Seo, Eunseok; Lim, Jun; Baek, Miok; Lee, Sang Joon

    2016-05-01

    We have previously reported the discovery of a novel fibrous structure (NFS) consisting of unidirectionally arranged collagen fibers in the spinal pia mater. Due to its unique structure, it was easily detected using polarized light microscopy. In the current study, we describe the discovery of a similar NFS in the brain meninges of rats by using polarized light microscopy. This NFS is located beneath the superior sagittal sinus. Initially, we systemically analyzed the polarization properties of the NFS. The change in the light intensity of the NFS, with respect to the polarization angle, was eight times greater than that of blood vessels, showing that the collagen fibers are oriented in a particular direction with almost perfect parallelism (0.99). The orientation angle of the polarization ellipse confirmed the orientation of the collagen fibers in the NFS. Histological studies further confirmed that the unidirectionally arranged collagen fibers were responsible for this distinct polarization property. Surprisingly, X-ray microtomography and 3D confocal imaging revealed that the NFS contains within it a duct structure, a putative primo vessel. In conclusion, we report a NFS in the brain meninges, detected by using polarized light microscopy, that provides space for a putative primo vessel, not a blood vessel.

    Full Text Available Extraosseous Ewing’s sarcoma (EES involving the central nervous system is rare, but can be diagnosed and distinguished from other primitive neuroectodermal tumors (PNET by identification of the chromosomal translocation (11;22(q24;q12. We report EES arising from the spinal intradural extramedullary space, based on imaging, histopathological, and molecular data in two men, ages 50 and 60 years old and a review of the literature using PubMed (1970-2009. Reverse transcriptase polymerase chain reaction (RT-PCR identified the fusion product FL1-EWS. Multimodal therapy, including radiation and alternating chemotherapy including vincristine, cyclophosphamide, doxorubicin and ifosfamide and etoposide led to local tumor control and an initial, favorable therapeutic response. No systemic involvement was seen from the time of diagnosis to the time of last follow-up (26 months or death (4 years. This report confirms that EES is not confined to the earliest decades of life, and like its rare occurrence as an extra-axial meningeal based mass intracranially, can occasionally present as an intradural mass in the spinal canal without evidence of systemic tumor. Gross total resection followed by multimodal therapy may provide for extended progression free and overall survival.

    2009-10-30

    Extrinsic signals controlling generation of neocortical neurons during embryonic life have been difficult to identify. In this study we demonstrate that the dorsal forebrain meninges communicate with the adjacent radial glial endfeet and influence cortical development. We took advantage of Foxc1 mutant mice with defects in forebrain meningeal formation. Foxc1 dosage and loss of meninges correlated with a dramatic reduction in both neuron and intermediate progenitor production and elongation of the neuroepithelium. Several types of experiments demonstrate that retinoic acid (RA) is the key component of this secreted activity. In addition, Rdh10- and Raldh2-expressing cells in the dorsal meninges were either reduced or absent in the Foxc1 mutants, and Rdh10 mutants had a cortical phenotype similar to the Foxc1 null mutants. Lastly, in utero RA treatment rescued the cortical phenotype in Foxc1 mutants. These results establish RA as a potent, meningeal-derived cue required for successful corticogenesis.

  11. Intraventricular antibiotics for bacterial meningitis in neonates.

    Shah, Sachin S; Ohlsson, Arne; Shah, Vibhuti S

    2012-07-11

    Neonatal meningitis may be caused by bacteria, especially gram-negative bacteria, which are difficult to eradicate from the cerebrospinal fluid (CSF) using safe doses of antibiotics. In theory, intraventricular administration of antibiotics would produce higher antibiotic concentrations in the CSF than intravenous administration alone, and eliminate the bacteria more quickly. However, ventricular taps may cause harm. To assess the effectiveness and safety of intraventricular antibiotics (with or without intravenous antibiotics) in neonates with meningitis (with or without ventriculitis) as compared to treatment with intravenous antibiotics alone. The Cochrane Library, Issue 2, 2007; MEDLINE; EMBASE; CINAHL and Science Citation Index were searched in June 2007. The Oxford Database of Perinatal Trials was searched in June 2004. Pediatric Research (abstracts of proceedings) were searched (1990 to April 2007) as were reference lists of identified trials and personal files. No language restrictions were applied.This search was updated in May 2011. Selection criteria for study inclusion were: randomised or quasi-randomised controlled trials in which intraventricular antibiotics with or without intravenous antibiotics were compared with intravenous antibiotics alone in neonates (antibiotics compared to the group receiving intravenous antibiotics alone (RR 3.43; 95% CI 1.09 to 10.74; RD 0.30; 95% CI 0.08 to 0.53); NNTH 3; 95% CI 2 to 13). Duration of CSF culture positivity did not differ significantly (MD -1.20 days; 95% CI -2.67 to 0.27). In one trial that enrolled infants with gram-negative meningitis and ventriculitis, the use of intraventricular antibiotics in addition to intravenous antibiotics resulted in a three-fold increased RR for mortality compared to standard treatment with intravenous antibiotics alone. Based on this result, intraventricular antibiotics as tested in this trial should be avoided. Further trials comparing these interventions are not justified in

  12. CHEMICAL VERSUS SERUM TREATMENT OF EPIDEMIC MENINGITIS.

    Flexner, S; Amoss, H L

    1916-05-01

    Claims of efficiency have been made at two widely separated periods for the chemical treatment of epidemic meningitis, in the first instance for lysol and in the second for protargol. The use of lysol was long since abandoned; the recommendation for protargol is based on a single series of cases, small in number. Because of the variable severity of epidemics of meningitis, small reliance can be placed on results of treatment limited in extent to small numbers of cases and to one locality. A more uniform and accurate measure of the value of a method of treatment is provided by animals infected experimentally with pathogenic cultures of meningococci. Young guinea pigs respond in a definite manner to intraperitoneal inoculation of virulent meningococci. Neither protargol nor lysol proved to have any curative action on the experimental infection thus produced in these animals. Monkeys respond in a characteristic manner to the inoculation of virulent cultures into the subarachnoid space. Protargol displayed no curative action on the experimental infection thus produced in these animals. On the contrary, both lysol and protargol exert antileukotactic and antiphagocytic effects, and are also potent protoplasmic poisons, and the leukocytes with which they come in contact are injured and made to degenerate. According to the extent to which these harmful properties are exerted, the chemicals promote the advance rather than restrain the progress of meningococcic infection. Recovery from meningococcic infection in man and animals is accomplished chiefly through the process of phagocytosis. The specific antiserum acts curatively by increasing the emigration of leukocytes, by promoting phagocytosis directly, and by agglutinating the meningococci, and also by neutralizing endotoxin. Any means which interfere with and reduce these essential processes retard or prevent recovery. Both lysol and protargol interfere with and diminish the emigration of leukocytes and the phagocytosis

    1992-01-01

    The locations of cerebral infarctions were studied in 14 patients with tuberculous meningitis (TBM) and 173 patients with noninflammatory ischemic stroke (IS). In patients with TBM, 75% of infarctions occurred in the 'TB zone' supplied by medial striate and thalamoperforating arteries; only 11% occurred in the 'IS zone' supplied by lateral striate, anterior choroidal and thalamogeniculate arteries. In patients with IS, 29% of infarctions occurred in the IS zone, 29% in the subcortical white matter, and 24% in (or involving) the cerebral cortex. Only 11% occurred in the TB zone. Bilaterally symmetrical infarctions of the TB zone were common with TBM (71%) but rare with IS (5%). (orig.)

    1996-01-01

    The purpose of this study was to evaluate the usefulness of computed tomography(CT) and magnetic resonance imaging(MRI) in experimental bacterial meningitis. CT and MR images of experimental bacterial meningitis were obtained after inoculation of 1ml suspension of 10-6/ml Staphylococcus aureus directly into the supratentorial arachnoid space of 18 New Zealand white rabbits. Each animal was studied with both pre-enhanced and post-enhanced CT and MRI at 12, 24, 48 hours and 1 week. Cerebrospinal fluid of all of 18 rabbits were sampled and cultured for bacterial growth. All of 18 rabbits had the clinical symptoms such as neck stiffness and anorexia within 24 hours after the inoculation. Cerebrospinal fluid cultures were positive for Staphylococcus aureus growth. Gd-enhanced MRI exhibited diffuse enhancement along the thickened supratentorial meninges earlier than CT. In Gd-enhanced MRI, the mean contrast enhancement along the thickened supratentorial meninges earlier than CT. In Gd-enhanced MRI, the mean contrast enhancement ratio(CER) at supratentorial meninges increased to 1.93 at 12 hours and 2.99 at 24 hours from 1.06 at 0 hour. Histologic evaluation demonstrated inflammatory cell infiltration into the meninges. MRI also identified the complications of meningitis such as ependymitis and hydrocephalus more effectively than CT. These results indicated that Fd-enhanced MRI detectred earlier the abnormal findingfs of bacterial meningitis and evaluated more effectively the complications of meningitis compared with CT. MRI was more useful than CT in evaluation of the bacterial meningitis

In Gd-enhanced MRI, the mean contrast enhancement ratio(CER) at supratentorial meninges increased to 1.93 at 12 hours and 2.99 at 24 hours from 1.06 at 0 hour. Histologic evaluation demonstrated inflammatory cell infiltration into the meninges. MRI also identified the complications of meningitis such as ependymitis and hydrocephalus more effectively than CT. These results indicated that Fd-enhanced MRI detectred earlier the abnormal findingfs of bacterial meningitis and evaluated more effectively the complications of meningitis compared with CT. MRI was more useful than CT in evaluation of the bacterial meningitis.

    A high dose of anti-infective agents is recommended when treating infectious meningitis. High creatinine clearance (CrCl) may affect the pharmacokinetic / pharmacodynamic relationships of anti-infective drugs eliminated by the kidneys. We recorded the incidence of high CrCl in intensive care unit (ICU) patients admitted with meningitis and assessed the diagnostic accuracy of two common methods used to identify high CrCl. Observational study performed in consecutive patients admitted with community-acquired acute infectious meningitis (defined by >7 white blood cells/mm3 in cerebral spinal fluid) between January 2006 and December 2009 to one medical ICU. During the first 7 days following ICU admission, CrCl was measured from 24-hr urine samples (24-hr-UV/P creatinine) and estimated according to Cockcroft-Gault formula and the simplified Modification of Diet in Renal Disease (MDRD) equation. High CrCl was defined as CrCl >140 ml/min/1.73 m2 by 24-hr-UV/P creatinine. Diagnostic accuracy was performed with ROC curves analysis. Thirty two patients were included. High CrCl was present in 8 patients (25%) on ICU admission and in 15 patients (47%) during the first 7 ICU days for a median duration of 3 (1-4) days. For the Cockcroft-Gault formula, the best threshold to predict high CrCl was 101 ml/min/1.73 m2 (sensitivity: 0.96, specificity: 0.75, AUC = 0.90 ± 0.03) with a negative likelihood ratio of 0.06. For the simplified MDRD equation, the best threshold to predict high CrCl was 108 ml/min/1.73 m2 (sensitivity: 0.91, specificity: 0.80, AUC = 0.88 ± 0.03) with a negative likelihood ratio of 0.11. There was no difference between the estimated methods in the diagnostic accuracy of identifying high CrCl (p = 0.30). High CrCl is frequently observed in ICU patients admitted with community-acquired acute infectious meningitis. The estimated methods of CrCl could be used as a screening tool to identify high CrCl.

    Streptococcus mitis, an important member of viridans streptococci, is found in the normal flora of the oropharynx, gastrointestinal tract, female genital tract and skin. Although it is of low pathogenicity and virulence, it may cause serious infections in immunocompromised patients. Meningitis caused by S.mitis has been described in patients with previous spinal anesthesia, neurosurgical procedure, malignancy, bacterial endocarditis with neurological complications and alcoholics, but it is rare in patients who are previously healthy. In this report, a rare case of meningoencephalitis caused by S.mitis developed in a previously healthy child has been presented. A previously healthy eight-year-old girl who presented with fever, altered state of consciousness, and headache was hospitalized in intensive care unit with the diagnosis of meningitis. Past history revealed that she was treated with amoxicillin-clavulanate for acute sinusitis ten days before her admission. Whole blood count revealed the followings: hemoglobin 13 g/dl, white blood cell count 18.6 x 109/L (90% neutrophils), platelet count 200 x 109/L and 150 leucocytes were detected on cerebrospinal fluid (CSF) examination. Protein and glucose levels of CSF were 80 mg/dl and 40 mg/dl (concomitant blood glucose 100 mg/dl), respectively. Brain magnetic resonance imaging (MRI) revealed widespread white matter lesions, and alpha-hemolytic streptococci were grown in CSF culture. The isolate was identified as S.mitis with conventional methods, and also confirmed by VITEK2 (bioMerieux, France) and API 20 STREP (bioMerieux, France) systems. Isolate was found susceptible to penicillin, erythromycin, clindamycin, tetracycline, cefotaxime, vancomycin and chloramphenicol. Regarding the etiology, echocardiography revealed no vegetation nor valve pathology, and peripheral blood smear showed no abnormality. Immunoglobulin and complement levels were within normal limits. Ongoing inflammation in maxillary sinuses detected in

    Objective: To determine the frequencies and percentages of various clinicoradiologic variables of tuberculosis meningitis (TBM) with reference to British Medical Research Council (BMRC) staging of the disease. Study Design: A case series. Place and Duration of Study: Department of Neurology, Jinnah Postgraduate Medical Centre, Karachi, from October 2010 to September 2011. Methodology: The study included 93 adult patients with the diagnosis of tuberculous meningitis (TBM) at the study place. Patients were divided in three groups according to British Medical Research Council (BMRC) staging of TBM. Different clinical and radiological findings were analyzed at different stages of the disease. Data was analyzed using SPSS (Statistical Package of Social Sciences) version 11.0. Results: A majority of patients were found to be in stage-II disease at the time of admission. History of illness at the time of admission was more than 2 weeks in 50% of stage-I patients but around 80% in stage-II and stage-III patients. Neck stiffness was the most commonly reported finding in all stages. Cranial nerve palsies were higher in stage-III (75%) than in stage-II (43%) and in stage-I (24%) patients. Hydrocephalus and basal enhancement was the most frequently reported radiographic abnormalities. Conclusion: Duration of illness and cranial nerve palsies are important variables in the diagnosis of TBM stages and if TBM is suspected, empiric treatment should be started immediately without bacteriologic proof to prevent morbidity and mortality.

    Vicuña-González, R M; Rivera-Salgado, M I; García-Velarde, P M Pasquel; de León-Bojorge, B; Ortiz-Hidalgo, C

    Inflammatory pseudotumor is a reactive process in which the etiology and pathogenesis are not well defined, that can be found in any location. The cases with central nervous system affection have been described in meninges, brain, choroid plexus and cranial and spinal nerves. Multicentric cases, synchronous and asynchronous have been described. A 45 years-old woman with a rheumatologic disease (a seronegative spondiloarthropathy) who developed an inflammatory pseudotumor in spleen, liver and abdominal lymph nodes in 1995, associated to fever of unknown origin, six years later she presented with an inflammatory pseudotumor of the meninges in the convexity of the right frontoparietal region, with fever, malaise, and increase of globular sedimentation rate, microcytic hypochromic anemia and thrombocytosis. The clinicopathologic features of this lesion are revised, including the different theories in regard to the etiology and pathogenesis, and the role of cytokines produced by inflammatory cells in the tumor.

    Spinal injuries are very common among professional or amateur athletes. Spinal sport lesions can be classified in overuse and acute injuries. Overuse injuries can be found after years of repetitive spinal load during sport activity; however specific overuse injuries can also be found in adolescents. Acute traumas are common in contact sports. Most of the acute injuries are minor and self-healing, but severe and catastrophic events are possible. The aim of this article is to review the wide spectrum of spinal injuries related to sport activity, with special regard to imaging finding.

  3. Spinal CT scan, 1

    Nakagawa, Hiroshi

    1982-01-01

    Methods of CT of the cervical and thoracic spines were explained, and normal CT pictures of them were described. Spinal CT was evaluated in comparison with other methods in various spinal diseases. Plain CT revealed stenosis due to spondylosis or ossification of posterior longitudinal ligament and hernia of intervertebral disc. CT took an important role in the diagnosis of spinal cord tumors with calcification and destruction of the bone. CT scan in combination with other methods was also useful for the diagnosis of spinal injuries, congenital anomalies and infections. (Ueda, J.)

  4. MULTIPLE SPINAL CANAL MENINGIOMAS

    Nandigama Pratap Kumar

    2016-10-01

    Full Text Available BACKGROUND Meningiomas of the spinal canal are common tumours with the incidence of 25 percent of all spinal cord tumours. But multiple spinal canal meningiomas are rare in compare to solitary lesions and account for 2 to 3.5% of all spinal meningiomas. Most of the reported cases are both intra cranial and spinal. Exclusive involvement of the spinal canal by multiple meningiomas are very rare. We could find only sixteen cases in the literature to the best of our knowledge. Exclusive multiple spinal canal meningiomas occurring in the first two decades of life are seldom reported in the literature. We are presenting a case of multiple spinal canal meningiomas in a young patient of 17 years, who was earlier operated for single lesion. We analysed the literature, with illustration of our case. MATERIALS AND METHODS In September 2016, we performed a literature search for multiple spinal canal meningiomas involving exclusively the spinal canal with no limitation for language and publication date. The search was conducted through http://pubmed.com, a wellknown worldwide internet medical address. To the best of our knowledge, we could find only sixteen cases of multiple meningiomas exclusively confined to the spinal canal. Exclusive multiple spinal canal meningiomas occurring in the first two decades of life are seldom reported in the literature. We are presenting a case of multiple spinal canal meningiomas in a young patient of 17 years, who was earlier operated for solitary intradural extra medullary spinal canal meningioma at D4-D6 level, again presented with spastic quadriparesis of two years duration and MRI whole spine demonstrated multiple intradural extra medullary lesions, which were excised completely and the histopathological diagnosis was transitional meningioma. RESULTS Patient recovered from his weakness and sensory symptoms gradually and bladder and bowel symptoms improved gradually over a period of two to three weeks. CONCLUSION Multiple

    There is limited understanding of the epidemiology of meningitis among human immunodeficiency virus (HIV)-infected populations in sub-Saharan Africa. We conducted a prospective cohort study of HIV-infected adults with suspected meningitis in Uganda, to comprehensively evaluate the etiologies of meningitis. Intensive cerebrospiral fluid (CSF) testing was performed to evaluate for bacterial, viral, fungal, and mycobacterial etiologies, including neurosyphilis,16s ribosomal DNA (rDNA) polymerase chain reaction (PCR) for bacteria, Plex-ID broad viral assay, quantitative-PCR for HSV-1/2, cytomegalovirus (CMV), Epstein-Barr virus (EBV), and Toxoplasma gondii; reverse transcription-PCR (RT-PCR) for Enteroviruses and arboviruses, and Xpert MTB/RIF assay. Cryptococcal meningitis accounted for 60% (188 of 314) of all causes of meningitis. Of 117 samples sent for viral PCR, 36% were EBV positive. Among cryptococcal antigen negative patients, the yield of Xpert MTB/RIF assay was 22% (8 of 36). After exclusion of cryptococcosis and bacterial meningitis, 61% (43 of 71) with an abnormal CSF profile had no definitive diagnosis. Exploration of new TB diagnostics and diagnostic algorithms for evaluation of meningitis in resource-limited settings remains needed, and implementation of cryptococcal diagnostics is critical. © The American Society of Tropical Medicine and Hygiene.

    Full Text Available Objective: To evaluate the influence of environmental enrichment (EE on memory, cytokines, and brain-derived neurotrophic factor (BDNF in the brain of adult rats subjected to experimental pneumococcal meningitis during infancy. Methods: On postnatal day 11, the animals received either artificial cerebrospinal fluid (CSF or Streptococcus pneumoniae suspension intracisternally at 1 × 106 CFU/mL and remained with their mothers until age 21 days. Animals were divided into the following groups: control, control + EE, meningitis, and meningitis + EE. EE began at 21 days and continued until 60 days of age (adulthood. EE consisted of a large cage with three floors, ramps, running wheels, and objects of different shapes and textures. At 60 days, animals were randomized and subjected to habituation to the open-field task and the step-down inhibitory avoidance task. After the tasks, the hippocampus and CSF were isolated for analysis. Results: The meningitis group showed no difference in performance between training and test sessions of the open-field task, suggesting habituation memory impairment; in the meningitis + EE group, performance was significantly different, showing preservation of habituation memory. In the step-down inhibitory avoidance task, there were no differences in behavior between training and test sessions in the meningitis group, showing aversive memory impairment; conversely, differences were observed in the meningitis + EE group, demonstrating aversive memory preservation. In the two meningitis groups, IL-4, IL-10, and BDNF levels were increased in the hippocampus, and BDNF levels in the CSF. Conclusions: The data presented suggest that EE, a non-invasive therapy, enables recovery from memory deficits caused by neonatal meningitis.

  8. Primary cellular meningeal defects cause neocortical dysplasia and dyslamination

    Hecht, Jonathan H.; Siegenthaler, Julie A.; Patterson, Katelin P.; Pleasure, Samuel J.

    2010-01-01

    Objective Cortical malformations are important causes of neurological morbidity, but in many cases their etiology is poorly understood. Mice with Foxc1 mutations have cellular defects in meningeal development. We use hypomorphic and null alleles of Foxc1 to study the effect of meningeal defects on neocortical organization. Methods Embryos with loss of Foxc1 activity were generated using the hypomorphic Foxc1hith allele and the null Foxc1lacZ allele. Immunohistologic analysis was used to assess cerebral basement membrane integrity, marginal zone heterotopia formation, neuronal overmigration, meningeal defects, and changes in basement membrane composition. Dysplasia severity was quantified using two measures. Results Cortical dysplasia resembling cobblestone cortex, with basement membrane breakdown and lamination defects, is seen in Foxc1 mutants. As Foxc1 activity was reduced, abnormalities in basement membrane integrity, heterotopia formation, neuronal overmigration, and meningeal development appeared earlier in gestation and were more severe. Surprisingly, the basement membrane appeared intact at early stages of development in the face of severe deficits in meningeal development. Prominent defects in basement membrane integrity appeared as development proceeded. Molecular analysis of basement membrane laminin subunits demonstrated that loss of the meninges led to changes in basement membrane composition. Interpretation Cortical dysplasia can be caused by cellular defects in the meninges. The meninges are not required for basement membrane establishment but are needed for remodeling as the brain expands. Specific changes in basement membrane composition may contribute to subsequent breakdown. Our study raises the possibility that primary meningeal defects may cortical dysplasia in some cases.

    Cano Vargas-Machuca, E; Mondéjar-Marín, B; Navarro-Muñoz, S; Pérez-Molina, I; Garrido-Robres, J A; Alvarez-Tejerina, A

    Aseptic meningitis is a process that is characterised by an inflammatory reaction of the meninges that is not due to any infectious agent. Its aetiology is varied and is most frequently caused by rheumatologic and/or autoimmune processes, chemical or medication-induced meningitis, the most notable drugs involved being antibiotics and non-steroidal anti-inflammatory drugs (NSAI). We report the case of a 70-year-old male, with no relevant history, who was admitted to hospital five times over a period of 16 months because of acute meningitis with polymorphonuclear pleocytosis, high protein levels in cerebrospinal fluid and normal glucose in cerebrospinal fluid. No evidence of an infectious causation, chemical meningitis, carcinomatosis or autoimmune disease was found and the patient was diagnosed with recurrent aseptic meningitis. It was found that the patient had taken ibuprofen or ketorolac on several occasions, a few hours before the appearance of symptoms. These episodes were quickly resolved after withdrawal of this medication. A number of NSAI have been reported as inducers of aseptic meningitis, one of the most notable being ibuprofen. We report the case of a patient who, as a consequence of taking ibuprofen and ketorolac, presented episodes of recurrent aseptic meningitis. To our knowledge this side effect of ketorolac has not been reported before. Its clinical features are impossible to differentiate from those of infectious meningitis. Diagnosis is reached by exclusion and a careful pharmacological study, including over-the-counter drugs like some of the NSAI, must be performed in patients with this condition, since it is a problem that can easily be solved by withdrawing the drug that causes it.

    2015-01-01

    BACKGROUND: Colloid cysts are benign third ventricle lesions that need to be diagnosed correctly because of their association with sudden death. Chemical or aseptic meningitis is a rare presentation of a colloid cyst. METHODS: We present a case of a 69-year-old man with fever, alteration of mental...... status, and meningismus. Microbiological examination of the cerebrospinal fluid revealed aseptic meningitis. Brain imaging revealed a third ventricular colloid cyst with hydrocephalus. RESULTS: The tumor was resected via endoscopic intervention. There were no persistent operative complications related...... to the endoscopic procedure. CONCLUSIONS: Chemical or aseptic meningitis is an unusual clinical manifestation of a colloid cyst, complicating the differential diagnosis, especially in the elderly....

    A 73-year-old man was admitted to our hospital with disturbance of consciousness, fever and headache. Cerebrospinal fluid (CSF) analysis revealed pleocytosis with neutrophil predominance, increased protein and low glucose. CSF and blood cultures yielded negative results. Antibiotics and antituberculous drugs were started for meningitis. An antimycotic was also added. The patient died from transtentorial hernia 99 days after admission. Autopsy revealed meningitis, ventriculitis and brain abscess, and Nocardia araoensis was detected in pus from the left lateral ventricle. This appears to represent the first report of N. araoensis meningitis complicated by ventriculitis and brain abscess.

    A boy with bilateral hearing impairment developed pneumococcal meningitis at 14-month-old. Further examination revealed cerebrospinal fluid leakage due to bilateral Mondini dysplasia. He was cured by treatment with panipenem/betamiprone and dexamethasone, and then, he was performed an operation to fill the inner ear on day 30. He did not have bacterial meningitis 19 months after the operation. Children with congenital hearing impairment should be examined for malformation of the inner ear because the inner ear malformation has cerebrospinal fluid leakage and bacterial meningitis frequently.

    Mondini's dysplasia is a developmental anomaly of the middle ear characterized by cochlear malformation with dilation of the vestibular aquaduct, vestibule, and ampullar ends of the semicircular canals. These deformities may result in a connection between subarachnoid space and the middle ear resulting in recurrent episodes of meningitis. Additionally, it is commonly associated with hearing impairment. We describe here a boy with recurrent meningitis and unilateral sensorineural hearing loss. Mondini dysplasia was demonstrated with computed tomographic scans of the temporal bones in the search for pathogenesis of recurrent meningitis.

  14. Streptococcus suis Meningitis: First Case Reported in Quebec

    Sophie Michaud

    1996-01-01

    Full Text Available Very few Streptococcus suis infections in humans have been reported in Canada, although the condition is frequent in pigs. Meningitis, often accompanied by severe hearing loss, is the most common clinical manifestation. The disease is an occupational illness affecting persons in contact with pigs and may be underdiagnosed because of misidentification of the responsible bacterium. Since Quebec is the leading province for swine production in Canada, physicians and microbiologists should be aware of this infection, especially when a streptococcal meningitis is diagnosed in swine workers. The first case of S suis type 2 meningitis reported in Quebec is described.

    Full Text Available Chronic aseptic meningitis is a rare manifestation of systemic lupus erythematosus (SLE. Apart from immunological causes and drugs, the aseptic meningitis group can include some unidentified viral infections that cannot be detected by routine microbiological testing. It is imperative to do complete cerebrospinal fluid (CSF workup before implicating the symptoms to disease activity or drugs, as untreated infections cause significant mortality in SLE. We present a case of young female with SLE who presented with chronic meningitis of an uncommon etiology.

    Full Text Available Aim: The aim of our study was to evaluate the epidemiologic, clinic and laboratory results and the answers to treatment of meningitis cases. Material and Method: In this study, the epidemiologic, clinic and laboratory results of 197 patients hospitalized with central nervous system infection diagnosis in the Department of Pediatric Health and Diseases of the Faculty of Medicine of Dicle University between 1st of January 2003 and 1st of January 2006 have been studied retrospectively. The files have been studied in details for age, sex, complaints, and results of physical examination, laboratory results, radiological results and treatments applied. Results: 118 of the patients were male, 79 were women and the mean age calculated was 62,2±47,3 months.137, 27 and 33 patients have been respectively considered as ABM, AM and TM. The most frequent complaints of application to hospital were fever (95,4%, vomiting (82,7%, headache (45,6% and change of consciousness (21,3%. The presence of many risks about meningitis has been observed. The most frequent risk factors were head trauma history, parenchymal lung tuberculosis, military tuberculosis, presence of V-P shunt, meningocele, varicella history, having mumps, and the presence of purulent ear discharge. BOS has developed in 7 patients and for five patients, reproduction occurred in blood culture. The most important central nervous system sequels or complications were in order of frequency hydrocephalies requiring the installation of V-P shunt, brain edema, epilepsies, subdural effusions, tuberculoma, retention of head pair, and brain apses. The rate of mortality was (% 13,1. Discussion: During the period of execution of the study, the mortality and morbidity of central nervous system diseases were still at high risk. But this may be associated to the absence of vaccination programs for frequent meningitis factors such as pneumococcus and H. influenza were not in routine vaccination program in our

    2004-01-01

    Background: extracranial seeding of glioblastoma multiforme (GBM) is very rare and its development depends on several factors. This case report describes two patients suffering from GBM with spinal seeding. In both cases, the anatomic localization of the primary tumor close to the cerebrospinal fluid (CSF) was the main factor for spinal seeding. Case reports: two patients with GBM and spinal seeding are presented. After diagnosis of spinal seeding, both patients were highly symptomatic from their spinal lesions. Case 1 experienced severe pain requiring opiates, and case 2 had paresis of lower limbs as well as urinary retention/incontinence. Both patients were treated with spinal radiation therapy. Nevertheless, they died 3 months after diagnosis of spinal seeding. Results: in both patients the diagnosis of spinal seeding was made at the time of cranial recurrence. Both tumors showed close contact to the CSF initially. Even though the patients underwent intensive treatment, it was not possible to keep them in a symptom-free state. Conclusion: because of short survival periods, patients deserve optimal pain management and dedicated palliative care. (orig.)

  4. Chronic spinal subdural hematoma

    Hagen, T.; Lensch, T.

    2008-01-01

    Compared with spinal epidural hematomas, spinal subdural hematomas are rare; chronic forms are even more uncommon. These hematomas are associated not only with lumbar puncture and spinal trauma, but also with coagulopathies, vascular malformations and tumors. Compression of the spinal cord and the cauda equina means that the patients develop increasing back or radicular pain, followed by paraparesis and bladder and bowel paralysis, so that in most cases surgical decompression is carried out. On magnetic resonance imaging these hematomas present as thoracic or lumbar subdural masses, their signal intensity varying with the age of the hematoma. We report the clinical course and the findings revealed by imaging that led to the diagnosis in three cases of chronic spinal subdural hematoma. (orig.) [de

    Full Text Available Carcinomatous meningitis (CM occurs in 3 to 8% of cancer patients. Patients present with a focal symptom, and multifocal signs are often found following neurological examination. The gold standard for diagnosis remains the demonstration of carcinomatous cells in the cerebrospinal fluid on cytopathological examination. Despite the poor prognosis, palliative treatment could improve quality of life and, in some cases, overall survival. We report on a patient who presented with vertigo, tinnitus and left-sided hearing loss followed by progressive diffuse facial nerve paralysis. Lumbar cerebrospinal fluid confirmed the diagnosis of CM. However, no primary tumor was discovered, even after multiple invasive investigations. This is the first reported case in the English-language medical literature of CM resulting from a carcinoma of unknown primary origin.

  6. [Acute bacterial meningitis as an occupational disease].

    Seixas, Diana; Lebre, Ana; Crespo, Pedro; Ferreira, Eugénia; Serra, José Eduardo; Saraiva da Cunha, José Gabriel

    2014-01-01

    Streptococcus suis is a zoonotic pathogen with worldwide distribution, responsible for more than 700 human cases globally reported. This infection affects mostly men, exposed to pig or pork, which leads to its usual classification as an occupational disease. We report a case of acute bacterial meningitis in a 44 years old male. According to his past medical history, the patient had chronic alcoholism and worked in a restaurant as a piglet roaster. Microbiological examination of blood and CSF revealed S. suis. After 14 days of ceftriaxone the patient fully recovered. The authors review the clinical reports previously described in Portugal. In all of them was possible to identify risk exposition to pork. We alert to this microorganism's importance in Portugal where it is probably underdiagnosed.

  7. Telocytes in meninges and choroid plexus.

    Popescu, B O; Gherghiceanu, M; Kostin, S; Ceafalan, L; Popescu, L M

    2012-05-16

    Telocytes (TCs) are a recently identified type of interstitial cells present in a wide variety of organs in humans and mammals (www.telocytes.com). They are characterized by a small cell body, but extremely long cell processes - telopodes (Tp), and a specific phenotype. TCs establish close contacts with blood capillaries, nerve fibers and stem cells. We report here identification of TCs by electron microscopy and immunofluorescence in rat meninges and choroid plexus/subventricular zone, in the vicinity of putative stem cells. The presence of TCs in brain areas involved in adult neurogenesis might indicate that they have a role in modulation of neural stem cell fate. Copyright © 2012 Elsevier Ireland Ltd.

    Faurholt-Jepsen, Daniel; Lillebæk, Troels; Nielsen, Ming-Yuan

    2014-01-01

    In Denmark, tuberculous meningitis is rare. Central nervous system (CNS) involvement with Mycobacterium bovis is even rarer and has only been seen three times since 1992. We present a case of M. bovis meningitis in a previously healthy young Nigerian-born male, who had been exposed to unpasteurized...... dairy products in Nigeria but had no known contact with larger mammals. Before the development of meningitis, the patient had several contacts with the health system due to fever and non-specific symptoms. Finally, upon hospital admission, the patient was diagnosed with M. tuberculosis complex...... meningitis and treated empirically. After 13 days he was discharged without neurological sequelae. Later, the culture revealed M. bovis and treatment was adjusted accordingly....

  12. Isolated Torticollis May Present as an Atypical Presentation of Meningitis

    Roger Chirurgi

    2012-01-01

    Full Text Available Background. Bacterial meningitis is a life-threatening medical emergency that requires urgent diagnosis and treatment. Diagnosis is infrequently missed if the patient presents with the classic symptoms of fever, headache, rash, nuchal rigidity, or Kernig or Brudzinski sign. However, it may be less obvious in neonates, elderly, or immunocompromised patients. Meningitis which presents as isolated torticollis, without any other signs or symptoms, is exceedingly rare. Objective. To identify an abnormal presentation of meningitis in an adult immunocompromised patient. Case Report. We present a case of an adult diabetic male who presented multiple times to the ED with complaint of isolated torticollis, who ultimately was diagnosed with bacterial meningitis. Conclusion. We propose that in the absence of sufficient explanation for acute painful torticollis in an immunocompromised adult patient, further evaluation, possibly including a lumbar puncture may be warranted.

  18. Unrecognised ventriculitis/meningitis presenting as hydrocephalus in infancy.

    Udani, Vrajesh; Udani, Soonu; Merani, Rohan; Bavdekar, Manisha

    2003-09-01

    Infantile hydrocephalus due to unrecognized neonatal-onset meningitis/ventriculitis, was studied retrospectively using 1991-1998 chart review. Seventy two patients with hydrocephalus were reviewed. Thirteen infants had hydrocephalus associated with active meningitis/ventriculitis which had remained unrecognized. Active meningitis/ventriculitis was confirmed by the finding of an abnormal lumbar and ventricular CSF with or without positive culture. All had perinatal risk factors and 10/13 had been given antibiotics in the postnatal period. 6/13 infants appeared to be well. The most common presentation was increasing head size. All lumbar and ventricular CSFs were abnormal and 10/13 had positive cultures as well. Imaging revealed hydrocephalus in all. The infants were treated with antibiotics for a mean of 32.8 days before VP shunting. 7/11 were severely disabled. Unrecognized active meningitis/ventriculitis is an important cause of infantile hydrocephalus.

  20. Regulation of radial glial survival by signals from the meninges.

    Radakovits, Randor; Barros, Claudia S; Belvindrah, Richard; Patton, Bruce; Müller, Ulrich

    2009-06-17

    Radial glial cells (RGCs) in the developing cerebral cortex are progenitors for neurons and glia, and their processes serve as guideposts for migrating neurons. So far, it has remained unclear whether RGC processes also control the function of RGCs more directly. Here, we show that RGC numbers and cortical size are reduced in mice lacking beta1 integrins in RGCs. TUNEL stainings and time-lapse video recordings demonstrate that beta1-deficient RGCs processes detach from the meningeal basement membrane (BM) followed by apoptotic death of RGCs. Apoptosis is also induced by surgical removal of the meninges. Finally, mice lacking the BM components laminin alpha2 and alpha4 show defects in the attachment of RGC processes at the meninges, a reduction in cortical size, and enhanced apoptosis of RGC cells. Our findings demonstrate that attachment of RGC processes at the meninges is important for RGC survival and the control of cortical size.

  2. Meningococcal carriage in the African meningitis belt

    2013-01-01

    A meningococcal serogroup A polysaccharide/tetanus toxoid conjugate vaccine (PsA-TT) (MenAfriVac#x2122;) is being deployed in countries of the African meningitis belt. Experience with other polysaccharide/protein conjugate vaccines has shown that an important part of their success has been their ability to prevent the acquisition of pharyngeal carriage and hence to stop transmission and induce herd immunity. If PsA-TT is to achieve the goal of preventing epidemics, it must be able to prevent the acquisition of pharyngeal carriage as well as invasive meningococcal disease and whether PsA-TT can prevent pharyngeal carriage needs to be determined. To address this issue, a consortium (the African Meningococcal Carriage (MenAfriCar) consortium) was established in 2009 to investigate the pattern of meningococcal carriage in countries of the African meningitis belt prior to and after the introduction of PsA-TT. This article describes how the consortium was established, its objectives and the standardised field and laboratory methods that were used to achieve these objectives. The experience of the MenAfriCar consortium will help in planning future studies on the epidemiology of meningococcal carriage in countries of the African meningitis belt and elsewhere. Un vaccin conjugué contenant un polysaccharide du sérogroupe A méningococcique et une anatoxine du tétanos (PsA-TT) (MenAfriVac™) est en cours de déploiement dans les pays de la ceinture africaine de la méningite. L’ expérience avec d’ autres vaccins conjugués polysaccharide/protéine a montré qu’ une partie importante de leur succès a été leur capacité à empêcher l’ acquisition du portage pharyngé et donc à arrêter la transmission et à induire une immunité de group. Si PsA-TT doit d’ atteindre l’ objectif de prévenir les épidémies, il devrait être en mesure d’ empêcher l’ acquisition du portage pharyngé ainsi que la méningococcie invasive et le fait que PsA-TT puisse emp

    Liu, Yu-Ting; Lin, Chin-Fu; Lee, Ya-Ling

    2013-05-01

    We report a case of acute purulent meningitis caused by Streptococcus sanguinis after endoscopic ligation for oesophageal variceal haemorrhage in a cirrhotic patient without preceding symptoms of meningitis. Initial treatment with flomoxef failed. The patient was cured after 20 days of intravenous penicillin G. This uncommon infection due to S. sanguinis adds to the long list of infectious complications among patients with oesophageal variceal haemorrhage.

  6. Epidemiology of infectious meningitis in the State of Amazonas, Brazil

    Maria das Graças Gomes Saraiva

    2015-06-01

    Full Text Available INTRODUCTION: In the State of Amazonas, particularly in the capital Manaus, meningitis has affected populations of different cultures and social strata over the years. Bacterial meningitis is caused by several different species and represents a major issue of public health importance. The present study reports the meningitis case numbers with different etiologies in Amazonas from January 1976 to December 2012. METHODS: Since the 1970s, the (currently named Tropical Medicine Foundation of Doutor Heitor Vieira Dourado [Fundação de Medicina Tropical Doutor Heitor Vieira Dourado (FMT-HVD] has remained a reference center in Amazonas for the treatment of meningitis through the diagnosis and notification of cases and the confirmation of such cases using specific laboratory tests. RESULTS: The foundation has achieved coverage of over 90% of the state medical records for many years. Between 1990 and 2012, meningitis cases caused by Haemophilus influenzae decreased with the introduction of the H. influenzae vaccine. Meningococcal disease previously had a higher frequency of serogroup B disease, but starting in 2008, the detection of serogroup C increased gradually and has outpaced the detection of serogroup B. Recently, surveillance has improved the etiological definition of viral meningitis at FMT-HVD, with enteroviruses, Epstein-Barr virus (EBV and varicella zoster virus (VZV prevailing in this group of pathogens. With the advent of acquired immunodeficiency syndrome (AIDS, cryptococcal meningitis has become an important disease in Amazonas. Additionally, infectious meningitis is an important burden in the State of Amazonas. CONCLUSIONS: Changes in the epidemiological profile for the different etiology-defined cases are the result of continuous epidemiological surveillance and laboratory capacity improvements and control measures, such as Haemophilus influenzae vaccination.

  7. Chemical meningitis from a leaking craniopharyngioma: a case report.

    2018-06-01

    Recurrent chemical meningitis from cyclic leakage of cyst content from a craniopharyngioma is a rare phenomenon. Here, we report a case of leaking cystic craniopharyngioma presenting with recurrent episodes of sterile meningitis, depression, and paranoia. The diagnosis after an initial craniotomy and exploration was hypophysitis. Signs and symptoms were not alleviated by puncture and biopsy of the tumour but they disappeared after complete resection with a final histological diagnosis of craniopharyngioma.

    2011-05-01

    The authors report the case of 5-year-old girl who presented with 4 episodes of recurrent meningitis. Her initial workup revealed a lumbosacral dermoid sinus associated with diastematomyelia and a tethered cord. Therefore, a surgical repair to correct the anomaly was performed. However, another episode of meningitis occurred after surgery, and a subsequent temporal bone scan revealed the presence of left Mondini dysplasia. To the authors' knowledge, this is the first report of Mondini dysplasia in association with diastematomyelia.

    2017-09-01

    To determine age-stratified prevalence of concomitant bacterial meningitis in infants ≤60 days with a urinary tract infection, we performed a 23-center, retrospective study of 1737 infants with urinary tract infection. Concomitant bacterial meningitis was rare, but more common in infants 0-28 days of age [0.9%; 95% confidence interval (CI): 0.4%-1.9%) compared with infants 29-60 days of age (0.2%; 95% CI: 0%-0.8%).

  13. [Congenital skull base defect causing recurrent bacterial meningitis].

    Berliner, Elihay; Bar Meir, Maskit; Megged, Orli

    2012-08-01

    Bacterial meningitis is a life threatening disease. Most patients will experience only one episode throughout life. Children who experience bacterial meningitis more than once, require further immunologic or anatomic evaluation. We report a 9 year old child with five episodes of bacterial meningitis due to a congenital defect of the skull base. A two and a half year old boy first presented to our medical center with pneumococcal meningitis. He was treated with antibiotics and fully recovered. Two months later he presented again with a similar clinical picture. Streptococcus pneumoniae grew in cerebrospinal fluid (CSF) culture. CT scan and later MRI of the brain revealed a defect in the anterior middle fossa floor, with protrusion of brain tissue into the sphenoidal sinus. Corrective surgery was recommended but the parents refused. Three months later, a third episode of pneumococcal meningitis occurred. The child again recovered with antibiotics and this time corrective surgery was performed. Five years later, the boy presented once again with clinical signs and symptoms consistent with bacterial meningitis. CSF culture was positive, but the final identification of the bacteria was conducted by broad spectrum 16S ribosomal RNA PCR (16S rRNA PCR) which revealed a sequence of Neisseria lactamica. CT and MRI showed recurrence of the skull base defect with encephalocele in the sphenoid sinus. The parents again refused neurosurgical intervention. A year later the patient presented with bacterial meningitis. CSF culture obtained after initiation of antibiotics was negative, but actinobacillus was identified in the CSF by 16S rRNA PCR. The patient is scheduled for neurosurgical intervention. In patients with recurrent bacterial meningitis caused by organisms colonizing the oropharynx or nasopharynx, an anatomical defect should be carefully sought and surgically repaired.

  14. Computed tomography in cases of coccidioidal meningitis, with clinical correlation

    Shetter, A.G.; Fischer, D.W.; Flom, R.A.

    1985-01-01

    Cranial computed tomographic (CT) scans of 22 patients with coccidioidal meningitis were reviewed and their clinical course was analyzed. Abnormalities of the ventricular system or the basilar cisterns or both were present in 16 instances. Although it is not a definitive diagnostic tool, the CT scan is helpful in suggesting a diagnosis of coccidioidal meningitis and in predicting the prognosis of patients affected by the disease. 19 references, 4 figures, 2 tables

  15. CNS fungal meningitis to the "Top of the basilar"

    Logan CS; Kirschner RC; Simonds GR

    2013-01-01

    Central nervous system(CNS) infections are a rare complication of epidural steroid injections and without strong clinical suspicion, fungal organisms may be overlooked among the long differential of causes of meningitis.Rare sequela of fungal meningitis is the development of stroke.To our knowledge, we present the first case of post epidural steroid injection(ESI) fungal meningitis leading toa basilar artery stroke, otherwise known as“top of the basilar” syndrome.We present a49-year-old female with a history ofESIs who presented to the emergency department with headache, neck stiffness, and abdominal pain.She was discharged after her labs and symptoms were deemed inconsistent with meningitis.She was eventually admitted and twelve days after her originalED visit, she was diagnosed with meningitis and started on anti-fungal treatment.She was discharged88 days later but was readmitted due to left sided weakness and mental status changes.She quickly lost motor and bulbar functions.AnMRA showed diminished distal flow through the basilar artery, suggesting near complete occlusion.Although appropriate long term anti-fungal treatment was started, the patient still succumbed to a rare vascular event.Physicians who are treating patients forESI meningitis should be aware of the potential for vasculitic and encephalitic complications.

  16. Disorders of spinal blood circulation

    Hevyak, O.M.; Kuzminskyy, A.P.

    2017-01-01

    Spinal strokes are rare. The most common causes of the haemorrhage are spinal cord trauma, vasculitis with signs of haemorrhagic diathesis, spinal vascular congenital anomalies (malformations) and haemangioma. By localization, haemorrhagic strokes are divided into three groups: haematomyelia, spinal subarachnoid haemorrhage, epidural hematoma. Most cavernous malformations are localized at the cervical level, fewer — at thoracic and lumbar levels of the spinal cord. The clinical case of diagno...

    2008-09-01

    Full Text Available Se describe un caso de meningitis por Streptococcus suis en un paciente inmunocompetente. Presentaba astenia, debilidad generalizada, fiebre (39 °C, vómitos, deterioro del sensorio y desorientación témporo-espacial. Los cultivos de sangre (2/2 y de líquido cefalorraquídeo fueron positivos. La identificación preliminar se realizó utilizando las pruebas bioquímicas convencionales y fue completada en el Servicio Bacteriología Especial del INEI-ANLIS "Dr. Carlos G. Malbrán". Se comenzó el tratamiento con ampicilina y ceftriaxona. El microorganismo aislado demostró sensibilidad a ampicilina, cefotaxima y vancomicina. El paciente evolucionó favorablemente, pero se comprobó leve hipoacusia. Reingresó a los 4 meses con marcha atáxica, anacusia en oído izquierdo e hipoacusia en oído derecho. Continúa con seguimiento neurológico y audiométrico. Retrospectivamente se constató el contacto del paciente con cerdos. Se destaca la importancia de la anamnesis para alertar la sospecha de este agente etiológico en meningitis y bacteriemias.A case of Streptococcus suis meningitis is described in an immunocompetent patient presenting asthenia, general weakness, fever, vomiting, sensory deterioration and temporospatial disorder. The cerebrospinal fluid and two blood cultures (2/2 bottles were positive. The isolate was preliminary identified by conventional biochemical tests, and the identification was completed at the Special Bacteriology Service of INEI-ANLIS "Dr. Carlos G. Malbrán". Ampicillin and ceftriaxone treatment was initiated. The isolate was susceptible to ampicillin, cefotaxime and vancomycin. The patient experienced a good outcome but suffered hearing loss. However, after four months he returned with walking ataxia, deafness in his left ear, and hearing loss in the right ear. The patient’s retrospective exposure to pigs had been verified. It is important to evaluate predisposing and epidemiologic factors in order to alert about

    Full Text Available OBJECTIVE: Extradural arachnoid cysts (EACs are rare causes of spinal cord compression and cauda equina. These benign lesions appear in the literature mainly as single case reports. In this article, we present the largest series found in literature, with four new cases of spinal extradural arachnoid cysts. The characteristic imaging features, details of surgical steps and strategies to prevent postoperative kyphosis in this cystic pathology will be discussed.

  2. FDG PET in the diagnosis of meningeal carcinomatosis

    Guan, Y. H.; Zuo, C.T.; Zhao, J.; Hua, F.C.; Lin, X.T.

    2002-01-01

    Objective: Meningeal involvement is frequent in metastatic lymphoma, leukemia, and other metastatic tumor. Functional signs may be misleading and the neurological examination may be normal or non-specific. Certain diagnosis requires identification of tumor cells in the cerebrospinal fluid. CSF cytology is however sometimes negative and MRI maybe help in providing the diagnosis. The aim of our retrospective study was to assess the role of FDG PET in the diagnosis of meningeal carcinomatosis. Patients and Methods: The diagnosis of meningeal carcinomatosis was made in 5 patients between 1999 and 2001. Two of the patients were suffer from lymphoma, two were lung cancer patients, and another was a breast cancer patient. Cytology examination of the cerebrospinal fluid provided the diagnosis of meningeal carcinomatosis in these 5 patients. All the patients had signs of neurological function impairment, but the neurological examination cannot demonstrate the site of lesions. Therefore, All the patients had MRI examination, but only 1 case was diagnosis correctly (the MRI showing meningeal enhancement). 3 patients' MRI results show normal .Another MRI was suspicious of ischemic change. Results: A brain FDG PET using an ECAT HR + PET examined all the 5 patients. All the FDG PET results show the hypermetabolic foci respectively. The foci were diffused on the brain meninges. Their size is bigger than the foci detected by MRI . 3 of the patients repeated the FDG PET scan after treatment (chemotherapy and radiotherapy). The therapeutic effect can be reflecting by FDG PET (the foci dismissed as the neurological symptoms disappeared), although the simultaneity MRI shows no change before and after treatment. Conclusion: 5 patients proven meningeal carcinomatosis FDG PET has better sensitivity than brain MRI scans and other anatomic modality. The patients who suffer from metastatic lymphoma, leukemia, and other metastatic tumor with nonspecific neurological signs should be explored

    2003-01-01

    Objective.To investigate the magnetic resonance(MR)features of meningeal carcinomatosis,and to improve the ability in understanding and diagnosing meningeal carcinomatosis by MR findings. Methods. Eleven cases with proven meningeal carcinomatosis were studied by conventional and Gd-DTPA enhanced MR imaging. The enhancement patterns and features,as well as the types of meningeal involvement,were retrospectively analyzed. Results. Conventional MR imaging showed no evident meningeal abnormalities. After the administration of Gd-DTPA,abnormal pia mater enhancement was detected in 9 cases,demonstrating as the continuous,thin,and lineal high signal intensity on the brain surface that could descend into the sulci. The abnormal pial enhancement occurred on the cortical surfaces of cerebellum,brainstem,and cerebrum. No abnormal enhancement in the subarach-noid space was found. Abnormal dura-arachnoid enhancement was seen in 3 cases,showing as the continuous,thick,and curvilineal high signal intensity over the convexities or in the tentorium without extension into the cortical sulci. Cerebral dura-arachnoid involvement was found in all 3 cases and one of them also showed abnormal enhancement in cerebellar dura-arachnoid and tentorium. Of the 11 cases,9 with pial involvement had abnormal cerebrospinal fluid(CSF)results,2 involving only the dura-arachnoid had normal CSF results. Conclusion. Meningeal carcinomatosis could be well demonstrated by Gd-DTPA enhanced MR imaging,and its type could be differentiated by the enhancement features. Combined with the clinical information,Gd-enhanced MR imaging may lead to the diagnosis and guide the therapy of meningeal carcinomatosis.

    2013-08-01

    Serratia marcescens is a rare pathogen of central nervous system infections. This study was to investigate the epidemiology, prognostic factors, and treatment outcomes of S. marcescens meningitis. This retrospective analysis included 33 patients with culture-proven S. marcescens meningitis hospitalized between January 2000 and June 2011. Of the 33 patients enrolled, only one did not receive neurosurgery before the onset of S. marcescens meningitis. Patients with S. marcescens meningitis had higher ratios of brain solid tumors (54.5%) and neurosurgery (97.0%) with a mortality rate of 15.2%. The mean interval between the first neurosurgical procedure and the diagnosis of meningitis was 17.1 days (range, 4-51 days). Only one third-generation cephalosporin-resistant S. marcescens isolate was recovered from the patients' cerebrospinal fluid (CSF) specimens. Compared with the favorable outcome group (n = 20), the unfavorable outcome group (n = 13) had a higher percentage of brain solid tumors, more intensive care unit stays, and higher Sequential Organ Failure Assessment score, CSF lactate and serum C-reactive protein concentrations at diagnosis of meningitis. Under the multiple regression analysis, CSF lactate concentration ≥2-fold the upper limit of normal (ULN) was independently associated with unfavorable outcomes (odds ratio, 7.20; 95% confidence interval, 1.08-47.96; p = 0.041). S. marcescens meningitis is highly associated with neurosurgical procedures for brain solid tumors. CSF lactate concentration ≥2x ULN may predict an unfavorable outcome. Its mortality is not high and empiric treatment with parenteral third-generation cephalosporins may have a satisfactory clinical response. Copyright © 2012. Published by Elsevier B.V.

  5. Pediatric spinal infections

    Raj Kumar

    2014-01-01

    Full Text Available The infections of the spinal axis in children are rare when compared with adults. They encompass a large spectrum of diseases ranging from relatively benign diskitis to spinal osteomyleitis and to the rapidly progressive, rare, and potentially devastating spinal epidural, subdural, and intramedullary spinal cord infections. We present a comprehensive review of the literature pertaining to these uncommon entities, in light of our experience from northern India. The most prevalent pediatric spinal infection in Indian scenario is tuberculosis, where an extradural involvement is more common than intradural. The craniovertebral junction is not an uncommon site of involvement in children of our milieu. The majority of pyogenic infections of pediatric spine are associated with congenital neuro-ectodermal defects such as congenital dermal sinus. The clinico-radiological findings of various spinal infections commonly overlap. Hence the endemicity of certain pathogens should be given due consideration, while considering the differential diagnosis. However, early suspicion, rapid diagnosis, and prompt treatment are the key factors in avoiding neurological morbidity and deformity in a growing child.

  6. [Mondini dysplasia: recurrent bacterial meningitis in adolescence].

    Vargas-Dĭaz, J; Garófalo-Gómez, N; Rodríguez, U; Parra, M; Barroso-García, E; Novoa-López, L; Rojas-Massipe, E; Sardiñas-Hernández, N L

    Episodes of recurrent bacterial meningitis can occur in patients due to either congenital or acquired disorders. Congenital deformity of the bony labyrinth can be linked to a fistulous tract communicating it with the intracranial subarachnoid space. Mondini deformity is a frequent malformation in congenitally deaf patients. We report the case of an adolescent with a history of being unable to hear in one ear who, from the age of 10 years, began to suffer repeated bacterial meningoencephalitis with microbiological recovery of Streptococcus pneumoniae on three occasions. The type of germ recovered in the cerebrospinal fluid (CSF) and the history of congenital deafness that was detected when the patient was 3 years old were the diagnostic clues to the possible anomaly of the inner ear with a CSF fistula. The clinically proven CSF rhinorrhea contributed to the diagnosis of an ear anomaly with a fistula. Computerised axial tomography and magnetic resonance studies of the petrous portion of the temporal bone revealed the malformation that was later found and closed during the surgical intervention on the affected ear. The clinical absence of rhinorrhea, a year's progression without new infections after operating on the patient and post-surgery imaging studies were all proof that the fistula had closed. Mondini dysplasia with CSF fistula must be included as a possible diagnosis when faced with a patient with recurrent bacterial meningoencephalitis. Imaging studies, especially magnetic resonance, enable the clinician to check the diagnosis and the CSF fistula can be closed with ear surgery.

  7. Tuberculous Meningitis: Diagnosis and Treatment Overview

    Grace E. Marx

    2011-01-01

    Full Text Available Tuberculous meningitis (TBM is the most common form of central nervous system tuberculosis (TB and has very high morbidity and mortality. TBM is typically a subacute disease with symptoms that may persist for weeks before diagnosis. Characteristic cerebrospinal fluid (CSF findings of TBM include a lymphocytic-predominant pleiocytosis, elevated protein, and low glucose. CSF acid-fast smear and culture have relatively low sensitivity but yield is increased with multiple, large volume samples. Nucleic acid amplification of the CSF by PCR is highly specific but suboptimal sensitivity precludes ruling out TBM with a negative test. Treatment for TBM should be initiated as soon as clinical suspicion is supported by initial CSF studies. Empiric treatment should include at least four first-line drugs, preferably isoniazid, rifampin, pyrazinamide, and streptomycin or ethambutol; the role of fluoroquinolones remains to be determined. Adjunctive treatment with corticosteroids has been shown to improve mortality with TBM. In HIV-positive individuals with TBM, important treatment considerations include drug interactions, development of immune reconstitution inflammatory syndrome, unclear benefit of adjunctive corticosteroids, and higher rates of drug-resistant TB. Testing the efficacy of second-line and new anti-TB drugs in animal models of experimental TBM is needed to help determine the optimal regimen for drug-resistant TB.

  8. Culture Negative Listeria monocytogenes Meningitis Resulting in Hydrocephalus and Severe Neurological Sequelae in a Previously Healthy Immunocompetent Man with Penicillin Allergy

    Shahin Gaini

    2015-01-01

    Full Text Available A previously healthy 74-year-old Caucasian man with penicillin allergy was admitted with evolving headache, confusion, fever, and neck stiffness. Treatment for bacterial meningitis with dexamethasone and monotherapy ceftriaxone was started. The cerebrospinal fluid showed negative microscopy for bacteria, no bacterial growth, and negative polymerase chain reaction for bacterial DNA. The patient developed hydrocephalus on a second CT scan of the brain on the 5th day of admission. An external ventricular catheter was inserted and Listeria monocytogenes grew in the cerebrospinal fluid from the catheter. The patient had severe neurological sequelae. This case report emphasises the importance of covering empirically for Listeria monocytogenes in all patients with penicillin allergy with suspected bacterial meningitis. The case also shows that it is possible to have significant infection and inflammation even with negative microscopy, negative cultures, and negative broad range polymerase chain reaction in cases of Listeria meningitis. Follow-up spinal taps can be necessary to detect the presence of Listeria monocytogenes.

  12. CSF ADA Determination in Early Diagnosis of Tuberculous Meningitis in HIV-Infected Patients.

    Ghosh, Gopal Chandra; Sharma, Brijesh; Gupta, B B

    2016-01-01

    Tuberculous and Cryptococcal meningitis are common in HIV patients. A highly specific and sensitive rapid test for diagnosis of Tuberculous meningitis especially in setting of HIV is not available in developing countries where the burden of disease is high. We measured ADA (adenosine deaminase) levels using spectrophotometric method in the CSF of HIV patients with meningitis to differentiate Tuberculous meningitis from meningitis due to other causes. Kruskal-Wallis test was used to compare ADA values between tuberculous meningitis (TBM) and nontuberculous (non-TB) meningitis patients and a receiver-operating characteristic (ROC) analysis curve was drawn from these values. Levels of ADA in the CSF of patients with TBM were significantly higher than those in patients with meningitis due to other causes. CSF ADA level determination with a cut-off value of 6 IU/L was found to be highly specific and fairly sensitive test for the diagnosis of TBM in HIV positive patients.

    Congenital spinal malformations form a complex and heterogeneous group of disorders whose pathogenesis is best explained embryologically. Radiologically, it is important to formulate a diagnosis when the disorder first becomes symptomatic. However, it is also crucial to detect complications of the disorder or of the respective therapeutic interventions in the further course of the disease such as hydromyelia or re-tethering after repair of a meningomyelocele. Moreover, once a congenital spinal malformation is diagnosed, associated malformations should be sought after. A possible syndromal classification such as in OEIS- or VACTERL-syndromes should also be considered. (orig.) [German] Kongenitale spinale Malformationen stellen eine komplexe Gruppe an Stoerungen dar, deren Genese sich am einfachsten aus der Embryologie heraus erklaeren laesst. Bei der klinisch-radiologischen Begutachtung ist zunaechst ihre korrekte Klassifikation im Rahmen der Erstdiagnose wichtig. Im weiteren Verlauf ist es jedoch zudem entscheidend, moegliche Komplikationen wie beispielsweise eine Hydromyelie oder ein Wiederanheften des Myelons nach Operation einer Spina bifida aperta zu erkennen. Zudem sollte bei der Diagnosestellung einer kongenitalen spinalen Malformation immer auch auf assoziierte Fehlbildungen, wie z.B. die Diastematomyelie oder das intraspinale Lipom bei der Spina bifida aperta, sowie auf eine moegliche syndromale Einordnung wie beispielsweise beim OEIS-oder VACTERL-Syndrom geachtet werden.

  16. Human parasitic meningitis caused by Angiostrongylus cantonensis infection in Taiwan.

    Tsai, Hung-Chin; Chen, Yao-Shen; Yen, Chuan-Min

    2013-06-01

    The major cause of eosinophilic meningitis in Taiwan is Angiostrongylus cantonensis. Humans are infected by ingesting terrestrial and freshwater snails and slugs. In 1998 and 1999, two outbreaks of eosinophilic meningitis caused by A. cantonensis infection were reported among 17 adult male immigrant Thai laborers who had eaten raw golden apple snails (Pomacea canaliculata). Another outbreak associated with consuming a health drink consisting of raw vegetable juice was reported in 2001. These adult cases differed from reports in the 1970s and 1980s, in which most of the cases were in children. With improvements in public health and education of foreign laborers, there have since been only sporadic cases in Taiwan. Review of clinical research indicates inconsistent association of Magnetic Resonance Imaging (MRI) results with clinical features of eosinophilic meningitis. MRI features were nonspecific but there was an association between the presence of high brain MRI signal intensities and severity of peripheral and cerebrospinal fluid (CSF) eosinophilia. Inflammatory markers have been identified in the CSF of patients with eosinophilic meningitis caused by A. cantonensis infection, and vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), and the matrix metalloproteinase system may be associated with blood-brain barrier disruption. Eosinophilic meningitis caused by A. cantonensis infection is not a reportable disease in Taiwan. It is important that a public advisory and education program be developed to reduce future accidental infection.

  19. Continuous spinal anesthesia.

    Moore, James M

    2009-01-01

    Continuous spinal anesthesia (CSA) is an underutilized technique in modern anesthesia practice. Compared with other techniques of neuraxial anesthesia, CSA allows incremental dosing of an intrathecal local anesthetic for an indefinite duration, whereas traditional single-shot spinal anesthesia usually involves larger doses, a finite, unpredictable duration, and greater potential for detrimental hemodynamic effects including hypotension, and epidural anesthesia via a catheter may produce lesser motor block and suboptimal anesthesia in sacral nerve root distributions. This review compares CSA with other anesthetic techniques and also describes the history of CSA, its clinical applications, concerns regarding neurotoxicity, and other pharmacologic implications of its use. CSA has seen a waxing and waning of its popularity in clinical practice since its initial description in 1907. After case reports of cauda equina syndrome were reported with the use of spinal microcatheters for CSA, these microcatheters were withdrawn from clinical practice in the United States but continued to be used in Europe with no further neurologic sequelae. Because only large-bore catheters may be used in the United States, CSA is usually reserved for elderly patients out of concern for the risk of postdural puncture headache in younger patients. However, even in younger patients, sometimes the unique clinical benefits and hemodynamic stability involved in CSA outweigh concerns regarding postdural puncture headache. Clinical scenarios in which CSA may be of particular benefit include patients with severe aortic stenosis undergoing lower extremity surgery and obstetric patients with complex heart disease. CSA is an underutilized technique in modern anesthesia practice. Perhaps more accurately termed fractional spinal anesthesia, CSA involves intermittent dosing of local anesthetic solution via an intrathecal catheter. Where traditional spinal anesthesia involves a single injection with a

    2005-01-01

    Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year. Although the number of individuals sustaining paralysis is far less than those with moderate or severe brain injury, the socioeconomic costs are significant. Since most of the spinal trauma patients survive their injuries, almost one out of 1000 inhabitants in the USA are currently being cared for partial or complete paralysis. Little controversy exists regarding the need for accurate and emergent imaging assessment of the traumatized spine in order to evaluate spinal stability and integrity of neural elements. Because clinicians fear missing occult spine injuries, they obtain radiographs for nearly all patients who present with blunt trauma. We are influenced on one side by fear of litigation and the possible devastating medical, psychologic and financial consequences of cervical spine injury, and on the other side by pressure to reduce health care costs. A set of clinical and/or anamnestic criteria, however, can be very useful in identifying patients who have an extremely low probability of injury and who consequently have no need for imaging studies. Multidetector (or multislice) computed tomography (MDCT) is the preferred primary imaging modality in blunt spinal trauma patients who do need imaging. Not only is CT more accurate in diagnosing spinal injury, it also reduces imaging time and patient manipulation. Evidence-based research has established that MDCT improves patient outcome and saves money in comparison to plain film. This review discusses the use, advantages and disadvantages of the different imaging techniques used in spinal trauma patients and the criteria used in selecting patients who do not need imaging. Finally an overview of different types of spinal injuries is given

  2. Neurotrophic factors and receptors in the immature and adult spinal cord after mechanical injury or kainic acid.

    2001-05-15

    Delivery of neurotrophic factors to the injured spinal cord has been shown to stimulate neuronal survival and regeneration. This indicates that a lack of sufficient trophic support is one factor contributing to the absence of spontaneous regeneration in the mammalian spinal cord. Regulation of the expression of neurotrophic factors and receptors after spinal cord injury has not been studied in detail. We investigated levels of mRNA-encoding neurotrophins, glial cell line-derived neurotrophic factor (GDNF) family members and related receptors, ciliary neurotrophic factor (CNTF), and c-fos in normal and injured spinal cord. Injuries in adult rats included weight-drop, transection, and excitotoxic kainic acid delivery; in newborn rats, partial transection was performed. The regulation of expression patterns in the adult spinal cord was compared with that in the PNS and the neonate spinal cord. After mechanical injury of the adult rat spinal cord, upregulations of NGF and GDNF mRNA occurred in meningeal cells adjacent to the lesion. BDNF and p75 mRNA increased in neurons, GDNF mRNA increased in astrocytes close to the lesion, and GFRalpha-1 and truncated TrkB mRNA increased in astrocytes of degenerating white matter. The relatively limited upregulation of neurotrophic factors in the spinal cord contrasted with the response of affected nerve roots, in which marked increases of NGF and GDNF mRNA levels were observed in Schwann cells. The difference between the ability of the PNS and CNS to provide trophic support correlates with their different abilities to regenerate. Kainic acid delivery led to only weak upregulations of BDNF and CNTF mRNA. Compared with several brain regions, the overall response of the spinal cord tissue to kainic acid was weak. The relative sparseness of upregulations of endogenous neurotrophic factors after injury strengthens the hypothesis that lack of regeneration in the spinal cord is attributable at least partly to lack of trophic support.

    To determine the role of endogenous interleukin-18 (IL-18) in pneumococcal meningitis, meningitis was induced in IL-18 gene-deficient (IL-18(-/-)) and wild-type (WT) mice by intranasal inoculation of Streptococcus pneumoniae with hyaluronidase. Induction of meningitis resulted in an upregulation of

    A case of severe aseptic meningitis with communicating hydrocephalus following iotrolan myelography is presented. The patient's condition improved very quickly after corticosteroid therapy. Rapid improvement and absence of pathogenic organisms in the CSF culture strongly favor an aseptic meningitis. This is the first reported case of aseptic meningitis with the secondary development of hydrocephalus caused by iotrolan myelography.

    We report the case of a kidney transplantation patient on chronic immunosuppressive therapy presenting with subacute meningitis. The final diagnosis of cryptococcal meningitis was delayed due to 2 false-negative cryptococcal results on a molecular diagnostic panel. Caution with such platforms in suspected cryptococcal meningitis is needed.

    ABSTRACT Objective To measure the role of enterovirus detection in cerebrospinal fluid compared with the Bacterial Meningitis Score in children with meningitis. Methods A retrospective cohort based on analysis of medical records of pediatric patients diagnosed as meningitis, seen at a private and tertiary hospital in São Paulo, Brazil, between 2011 and 2014. Excluded were patients with critical illness, purpura, ventricular shunt or recent neurosurgery, immunosuppression, concomitant bacterial infection requiring parenteral antibiotic therapy, and those who received antibiotics 72 hours before lumbar puncture. Results The study included 503 patients. Sixty-four patients were excluded and 94 were not submitted to all tests for analysis. Of the remaining 345 patients, 7 were in the Bacterial Meningitis Group and 338 in the Aseptic Meningitis Group. There was no statistical difference between the groups. In the Bacterial Meningitis Score analysis, of the 338 patients with possible aseptic meningitis (negative cultures), 121 of them had one or more points in the Bacterial Meningitis Score, with sensitivity of 100%, specificity of 64.2%, and negative predictive value of 100%. Of the 121 patients with positive Bacterial Meningitis Score, 71% (86 patients) had a positive enterovirus detection in cerebrospinal fluid. Conclusion Enterovirus detection in cerebrospinal fluid was effective to differentiate bacterial from viral meningitis. When the test was analyzed together with the Bacterial Meningitis Score, specificity was higher when compared to Bacterial Meningitis Score alone. PMID:28767914

    Full Text Available Abstract Background Bacterial meningitis remains a source of substantial morbidity and mortality in childhood. During the last decades gradual changes have been observed in the epidemiology of bacterial meningitis, related to the introduction of new polysaccharide and conjugate vaccines. The study presents an overview of the epidemiological patterns of acute bacterial meningitis in a tertiary children 's hospital during a 32-year period, using information from a disease registry. Moreover, it discusses the contribution of communicable disease registries in the study of acute infectious diseases. Methods In the early 1970s a Meningitis Registry (MR was created for patients admitted with meningitis in Aghia Sofia Children's Hospital in Athens. The MR includes demographic, clinical and laboratory data as well as treatment, complications and outcome of the patients. In 2000 a database was created and the collected data were entered, analyzed and presented in three chronological periods: A (1974–1984, B (1985–1994 and C (1995–2005. Results Of the 2,477 cases of bacterial meningitis registered in total, 1,146 cases (46.3% were classified as "probable" and 1,331 (53.7% as "confirmed" bacterial meningitis. The estimated mean annual Incidence Rate (IR was 16.9/100,000 for bacterial meningitis, 8.9/100,000 for Neisseria meningitidis, 1.3/100,000 for Streptococcus pneumoniae, 2.5/100,000 for Haemophilus influenzae type b (Hib before vaccination and 0.4/100,000 for Hib after vaccination. Neisseria meningitis constituted the leading cause of childhood bacterial meningitis for all periods and in all age groups. Hib was the second most common cause of bacterial meningitis before the introduction of Hib conjugate vaccine, in periods A and B. The incidence of bacterial meningitis due to Streptococcus pneumoniae was stable. The long-term epidemiological pattern of Neisseria meningitidis appears in cycles of approximately 10 years, confirmed by a significant

    The results of contrast enhanced MRI in 36 patients with suspected spinal intradural tumours are described. All intramedullary tumours showed distinctive enhancement and solid tumors could be delineated clearly, even if they were not clearly visible on unenhanced scans. The differentiation between neoplasm and non-neoplastic syrinx was markedly improved. The sensitivity of MRI for demonstrating intradural extramedullary tumours was greatly improved by gadolinium DTPA and even small lesions or flat meningeal infiltrates could be visualised. In addition, gadolinium DTPA improved the delineation and localisation of larger lesions, even if they had already been seen on unenhanced images. (orig.) [de

    Guided by 9 own observations between 1977 and 1981, new diagnostic facilities in tuberculous meningitis are discussed. For differentiation from viral meningitis, measurement of CSF lactic acid concentration in addition to that of CSF glucose has proved to be of value in recent years. In accordance with the literature, two cases of this series which were examined for CSF lactic acid concentration showed markedly elevated levels of 8,4 rsp. 10,4 mmol/l. In contrast to this, in viral meningitis usually values of less than 3.5 mmol/l are found. Additionally, the presence of hypochlor- and hyponatremia, which could be demonstrated in 6 of our 9 patients, may raise the suspicion of tuberculous etiology. In the series presented, cranial computed tomography was of greatest diagnostic value, enabling the diagnosis of hydrocephalus internus in 5, and basal arachnoiditis in 2 cases. (orig.) [de

    Forty-three consecutive patients (16 with tumor, 11 with inflammation, 16 postoperative) with abnormal meningeal enhancement were studied. Positive pathology was obtained in 75% of tumors and 100% of inflammatory conditions. Pial enhancement was demonstrated in seven of 11 patients with inflammation, four of 16 with tumor, and two of 16 postoperative patients. Diffuse meningeal enhancement was most commonly present with neoplastic and inflammatory etiologies. Localized enhancement predominated in the postoperative population, unless complicated by a subdural hematoma. A nodular appearance was present in two patients with tumor. In conclusion, Gd-DTPA MR imaging is sensitive to but not specific of meningeal pathology. MR imaging is better in inflammatory than in neoplastic conditions

  16. Meningeal carcinomatosis as first manifestation of gastric carcinoma

    Romero R, Alfredo E; Mantilla H, Julio C; Melo U, Mario A; Barajas S, Paula A; Chinchilla O Sandra

    2009-01-01

    Meningeal carcinomatosis is defined as the malignant and widespread infiltration of the meninges due to the planting and growth of cancer cells within the leptomeningeal space. It occurs more frequently in patients with disseminated neoplastic disease, but it may occur after a disease free interval and may even be the first manifestation of cancer. The most common primary tumors in adults are breast (30-50%), lung (15-25%), melanoma (11%) and gastric cancer (0.16-0.69%); in marked contrast with pediatric cases in which lymphocytic leukemia is the most common. The following article describes an autopsy case of a patient with psychiatric symptoms, with no antecedents of importance, with progressive and fatal neurological impairment, whose pathological studies show meningeal carcinomatosis attributable to advanced gastric adenocarcinoma discovered de novo post mortem.

    Meningitis due to fracture of the fovea ethmoidalis during external dacryocystorhinostomy is a rare complication. We report a case of pneumocephalus and meningitis in a 51-year-old female who underwent an external dacryocystorhinostomy (DCR). Although extracranial complications during or after external DCR have been well-described, only one case of meningitis has been reported in the literature. Physical examination, computerised tomography, lumbar puncture, and bacteriologic cultures were used to make the diagnosis. The patient responded well to antibiotic therapy. Her symptoms resolved immediately and she was discharged on the 21st post-operative day. This complication emphasises the importance of careful surgical technique and a thorough knowledge of regional anatomy, during DCR and similar procedures.

    Meningitis is a life-threatening complication of otitis media. The appropriate management and the role of surgical intervention are still controversial, and there are no evidence-based guidelines in this regard. We report three cases of otogenic meningitis, initially treated with parenteral antibiotics and myringotomy, followed by surgery. Two patients had an emergency mastoidectomy and one patient underwent surgery one month post-recovery due to the suspicion of bone erosion on a computed tomography scan. In two cases, a canal wall up procedure was performed, and one patient underwent revision of a radical mastoidectomy. In all cases, no pus or granulations were seen in the mastoid. Two patients fully recovered and one patient died. We review the literature and critically discuss the role, timing and preferred type of surgery for otogenic meningitis.

  20. Vaccine preventable meningitis in Malaysia: epidemiology and management.

    McNeil, Hannah C; Jefferies, Johanna M C; Clarke, Stuart C

    Worldwide bacterial meningitis accounts for more than one million cases and 135,000 deaths annually. Profound, lasting neurological complications occur in 9-25% of cases. This review confirms the greatest risk from bacterial meningitis is in early life in Malaysia. Much of the disease burden can be avoided by immunization, particularly against Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae. Despite inclusion of the Hib vaccine in the National Immunisation Programme and the licensure of pneumococcal vaccines, these two species are the main contributors to bacterial meningitis in Malaysia, with Neisseria meningitidis and Mycobacterium tuberculosis, causing a smaller proportion of disease. The high Hib prevalence may partly be due to dated, small-scale studies limiting the understanding of the current epidemiological situation. This highlights the need for larger, better quality surveillance from Malaysia to evaluate the success of Hib immunization and to help guide immunization policy for vaccines against S. pneumoniae and N. meningitidis.
