Congenital visceral myofibromatosis is an uncommon disorder characterized by multiple tumors of myofibroblastic origin in the neonatal period. The natural history of the disorder has been well delineated. The myofibro blast is the cell of origin of the tumor. This is a report of a patient in whom multiple mesenchymal tumors occurred in the CNS as well as in other organs. Light and electron microiscopic findings of the CNS lesions are similar to those of the somites and viscera. 相似文献

Central nervous system (CNS) relapse in childhood acute lymphoblastic leukemia (ALL) has been overcome by sensitive therapatic approachs. This study was planned to present the development of CNS relapse and survival in newly diagnosed 190 ALL patients whose cases were followed in the authors' unit between March 1991 and May 2002. St. Jude Study XI protocol was given to the patients who applied between March 1991 and March 1997 (group A) (n = 122), and St. Jude Study XIII protocol was given to the patients who applied between March 1997 and May 2002 (group B) (n = 68). The patients having isolated CNS relapse in group A received craniospinal irradiation (CSI) median 3.5 months after CNS relapse (range 2–6 months), a short time after reinduction, and 2 cures of consolidation. In group B, patients having isolated CNS relapse received IT once a month and a high-dose methotrexate treatment once every 8 weeks and 3 or 4, cures later therapy CSI median 7 months after CNS relapse (range 6–8 months) was given. When the overall survival rates of the 2 groups are compared, a statistically significant higher survival rate at 5 years was determined in group B than in group A (respectively, 82.3%, 58.4%) (p < .05). When subgroups of the patients (that is, those with no relapse, isolated CNS or BM relapse, or CNS + BM relapse) were compared in both groups, it was found that survival was much higher for the ones with no relapse and with isolated CNS relapse (respectively, 87.9%, 72.7%) compared to isolated BM or CNS + BM relapse groups (respectively, 10%, 13.3%) (p < .05). In a conclusion, for children with acute lymphoblastic leukemia and an isolated CNS relapse, with delayed definitive craniospinal irradiation allowing more intensive systemic and intrathecal chemotherapy results in better overall survival than has been previously reported. 相似文献

Central nervous system (CNS) involvement in the context of hemophagocytic lymphohistiocytosis (HLH) is not uncommon. Given the immunosuppressive nature of HLH therapy, infectious complications are also seen. We describe a 9‐year‐old male who developed acute neurological decline secondary to aspergillosis while undergoing HLH therapy. The significant overlap observed in CNS neuroimaging of HLH and aspergillosis and the subtleties that may help differentiate the two are discussed. The importance of obtaining tissue for definitive diagnosis is underscored. 相似文献

Two male sibling infants died following a short course of lethargy and obtundation after a lifelong history of persistent, unrelenting diarrhea. Postmortem examination revealed extensive necrosis and early granuloma formation in the liver, spleen, lungs, and lymph nodes as well as in the central nervous system. To our knowledge, this fulminant clinical course, with documentation of granulomatous CNS lesions, has not been reported in patients with chronic granulomatous disease of childhood. 相似文献

Primary central nervous system Burkitt lymphoma (PCNSBL) is rare. Few cases of primary central nervous system involvement with sporadic Burkitt lymphoma have been reported and its treatment is now controversial. Here, the authors report a case of a 14-year-old boy suffering from non-immunoglobulin heavy chain (IgH) translocation PCNSBL. To the authors’ knowledge, this is the second case report describing primary Burkitt lymphoma involving cerebral ventricles. After receiving combination treatment with surgery, stereotactic radiosurgery, and a chemotherapy regimen including high-dose methotrexate, the patient had a disease-free survival of 18 months. 相似文献

Congenital malformations of the central nervous system (CNS) are among the most common anomalies, but data on the incidence
of CNS malformations in autopsy populations are scant. We examined 4122 autopsies between the years 1958 and 1995. There were
363 cases (8.8%) with CNS malformations; 235 were neonates and 128 stillborns. The overall gender ratio was 1:1, although
more male neonates and more female stillborns had malformations. The body weights ranged from 24 to 6440 g. Neural tube defects
were the most common types of malformations (45.5%) and included anencephaly, meningoencephalocele, meningocele/meningomyelocele,
craniospinal rachischisis, and spina bifida occulta. The incidences of other malformations were: congenital hydrocephalus
(12.4%), neuronal/glial proliferation disorders such as micro- and macrocephaly (8.8%), neuronal migration disorders (8.8%),
prosencephalon growth disorders such as holoprosencephaly and arhinencephaly (8.5%), abnormalities of the midline structures
such as agenesis of corpus callosum (4.1%), developmental cysts (3.3%), cerebellar malformations (3%), and vascular malformations
(2%). Miscellaneous malformations (3%) consisted of acephalia in four cases with twin reversed arterial perfusion (TRAP),
two cases of hydranencephaly, and four cases of rare degenerative and metabolic encephalopathies.

ABSTRACT. We studied sialic acid in the cerebrospinal fluid (CSF) of 52 children with leukemia and 51 children with non-leukemic diseases. The CSF sialic acid concentration in the children with central nervous system (CNS) leukemia was significantly higher than that in the children with acute lymphoblastic leukemia without CNS involvement, acute non-lymphocytic leukemia without CNS involvement, non-hemopoietic diseases, non-suppurative meningitis, epilepsy, and other neurologic diseases. Serial determinations revealed a rapid decline in the CSF sialic acid concentrations in the patients with CNS leukemia who responded well to the therapy and who were free from relapse of CNS leukemia. The simultaneously determined CSF β2 microglobulin concentration did not show any significant changes. These results suggest that the CSF sialic acid may be a good indicator of CNS leukemia. 相似文献

目的观察肺炎支原体肺炎(MPP)患儿中枢神经系统(CNS)损害情况,并探讨其机制。方法收集2007年1月-2009年3月本院收治的MPP患儿325例,观察合并CNS损害的症状和体征,对有CNS损害的患儿进一步检测其血清和脑脊液中IL-8、IL-18和可溶性白细胞介素-2受体(sIL-2R)水平。以同期住院的病毒性脑炎患儿作为对照组。采用SPSS12.0软件进行统计学分析。结果325例MPP患儿中,22例(6.8%)出现CNS损害,主要表现为发热、呕吐、头痛和惊厥。MPP并CNS损害患儿血清和脑脊液中IL-8、IL-18和sIL-2R水平明显高于对照组,特别是脑脊液中IL-18和sIL-2R水平(Pa<0.01)。MPP并CNS损害患儿血清和脑脊液中IL-18与sIL-2R均呈正相关(Pa<0.01)。结论MPP合并CNS损害患儿血清和脑脊液中IL-18和sIL-2R水平明显升高,可能与肺炎支原体导致CNS损害的发生有关。 相似文献
