Assessment of nutritional status in children with cancer: Significance of arm anthropometry and serum visceral proteins.

BACKGROUND: Arm anthropometry is a better indicator of nutritional status in children with cancer. The value of serum albumin and prealbumin in nutritional assesment is debatable. We investigated the nutritional status of children with cancer and their serum albumin and prealbumin levels. PATIENTS AND METHODS: At diagnosis and following induction therapies, weight, height, body mass index (BMI), mid-upper arm circumference (MUAC), and triceps skin-fold thickness (TSFT) were measured; serum albumin and prealbumin levels were determined. Prevalences of malnutrition defined by anthropometric indices were calculated. Correlations of anthropometric indices with each other, with serum albumin/prealbumin levels, and clinicopathological parameters were analyzed. RESULTS: In 81 patients, median age was 7.5 years (males/females = 50/31), tumors were located mostly in the abdomen, and abdominal tumors were more common under 5 years. Prevalence of malnutrition according to weight for age, BMI, MUAC, TSFT z scores were 14.8%, 23.5%, 27.2%, 21%, respectively. Defined by combined BMI/MUAC/TSFT measurements, 33/81 cases (40.7%) had malnutrition (z scores < -1, 23 mild; z scores < -2, 10 moderate). Malnutrition was more prevalent under 5 years (P = .03), also in abdominal tumors (P = .03) and advanced disease (P < .001). Younger age and advanced disease were risk factors for malnutrition. At diagnosis, prevalences of low serum albumin and prealbumin levels were 7.4% and 54%, respectively. Cases with malnutrition had significantly lower survival rates. CONCLUSIONS: Nutritional status is assessed best by MUAC and TSFT measurements. Serum prealbumin levels can be used to identify patients at risk of undernutrition. Presence of malnutrition is a significant poor prognostic factor. All children with cancer should undergo nutritional evaluation and active nutritional support.

Salivary gland tumors in children: a retrospective clinical review.

Seven patients with salivary gland tumors who underwent between 1972 and 2012 were retrospectively evaluated. The age of the patients ranged from 6.3 to 13 years old; five were females and two were males. Five patients had stage IVa, one patient had stage I, and one patient had stage II disease. The surgical margin was found to be positive in five cases. There were three adenoid cystic carcinoma, two adenocarcinoma, one anaplastic carcinoma, and one mucoepidermoid carcinoma. There were five parotid, one lacrimal gland, and one palatal involvement. Three patients who had low stage tumors were treated with surgery alone. Four of the cases received adjuvant radiation and chemotherapy. One patient with parotid tumor died with progressive disease. One case with lacrimal gland neoplasm was alive 48 months after discontinuation of treatment. The other palate case was lost to follow-up 1 month after the beginning of the treatment. Surgery is the primary treatment, with radiotherapy and chemotherapy used as adjuvant treatments. The treatment options need to be selected and planned for each individual patient.

Clinical features and treatment results of children with diffuse large B-cell lymphoma.

The demographic, clinical characteristics, and treatment groups of 33 children with diffuse large B-cell lymphoma (DLBCL) were recorded and analyzed among 1486 non-Hodgkin lymphoma (NHL) cases since 1972. The median age was 9.7 years (range 1.4-16.9) and male/female ratio was 24/9 = 2.6. Kaplan-Meier methods and logrank tests were used in treatment analysis. The frequency of DLBCL among 1486 NHL cases was 2.2%, however, the percentage was 9.3% in cases diagnosed after 2000. The event-free survival (EFS) and overall survival (OS) rates for 33 children were 61% and 65.1% at 5 years, respectively. The EFS and OS rates of low stage (stages I and II) disease decreased to lower level in advanced stage (stages III and IV) disease. Associated conditions and ages older than 14 years were found as poor prognostic factors in multivariate analysis. The survival rates in children with DLBCL need further improvement. This is mainly related with late referral of those children with advanced disease. The proper diagnosis and early referral is essential in these children for a better survival rate. The children with associated conditions and older children must be handled with care since these are found as poor prognostic factors.

Educational achievement, employment, smoking, marital, and insurance statuses in long-term survivors of childhood malignant solid tumors.

BACKGROUND/OBJECTIVE: Survivors of childhood cancer experience many social adaptation problems. We aimed to identify social, educational, and occupational issues of this growing population. PATIENTS AND METHODS: Survivors treated for childhood malignant solid tumors who were older than 18 years and in remission for at least 3 years were surveyed. The educational achievement, employment, type of habitation, marital status, parenthood, social insurance, and smoking status of the patients were inquired and recorded. RESULTS: Two hundred one patients (126 male patients/75 female patients) were included in the study between 2007 and 2009. The median ages at the time of diagnosis and at the time of study were 10 years (range, 0 to 19 y) and 23 years (range, 18 to 39 y), respectively. The median follow-up duration was 13.5 years (range, 3 to 31 y). Nearly half of the participants were lymphoma survivors. One hundred eleven (55.5%) survivors were high school graduates and 47 (23%) were university graduates. Unemployment rate was 36.8%. Public social insurance rate was 90.5%. Fifty-three (26.4%) survivors had independent habitation. Thirty percent of survivors were married and 7.5% had at least 1 child. Marriage rates were significantly higher in survivors who were older than 23 years, had a follow-up duration of >13 years, had a job, and lived independently (for each parameter P=0.001). University degree was significantly lower in survivors who were treated for central nervous system tumors. CONCLUSIONS: Our results have drawn a more marked picture with lower educational achievement and marital rates when compared with the results of large survivorship studies conducted in developed countries. However, they can be interpreted as intriguing when limited resources are taken into account.

Thyroid cancer in pediatric age group: an institutional experience and review of the literature.

Very few have been reported on children with differentiated thyroid cancer (DTC), although 15% of them are diagnosed below 20 years of age. Children with DTC present with more advanced disease; however, they have a more favorable outcome. In this paper, we aimed to present the data in our institution on pediatric DTC patients, making an emphasis on the risk factors of metastasis and recurrence, as well as to the outcome of treatment. Clinical data of 50 pediatric patients referred to our institution for radioiodine treatment (RAI) between 1976 and 2010 were obtained. Papillary carcinoma was the most common histopathologic diagnosis (36 patients) followed by papillary carcinoma with follicular variant (10 patients). Multifocality was reported in 66% of the pathology reports. At the time of diagnosis 35 patients had regional lymph node metastasis, 18 had local invasion, and 11 had distant metastasis. No distant metastasis was present in patients with unifocal disease (P=0.018). The mean duration of follow-up was 77.6±62.7 months. Patients with local disease had longer disease-free survival than patients with distant metastasis (P=0.033). Despite the small number of patients, the follow-up was relatively long and the presented results confirmed overall good prognosis in children with DTC.

Evaluation of patients with intracranial tumors and central diabetes insipidus.

The aim of the study is to evaluate the etiologic and clinical characteristics, treatment regimens, and outcome of the patients with intracranial tumors presenting with central diabetes insipidus (DI). Sixty-nine patients with intracranial tumors presenting with central DI between 1972 and 2012 were retrospectively evaluated. Fifty-three out of 69 patients were included in the analysis. Male/female ratio was 1.52, median age was 7.6 years. Of 53 patients, 37 patients (69.8%) were diagnosed with Langerhans cell histiocytosis, 14 patients (26.4%) with germinoma, 1 (1.9%) with astrocytoma, and 1 (1.9%) with optic glioma. 10-year overall survival (OS) rate and disease-free survival rate for all patients were 91.7% and 52%. 10-year OS rate according to diagnostic criteria was 91% for Langerhans cell histiocytosis (LCH) cases, 79% for intracranial germinoma, which was statistically significant (P = .0001). Central DI may be very important clinical presentation of serious underlying disease in children. Intracranial tumors are the most frequent cause of DI. Most frequent diagnosis were LCH and germ cell tumors in our series.

Infectious complications and conservative treatment of totally implantable venous access devices in children with cancer.

Besides their complications, totally implantable venous access devices (TIVADs) increase the quality of life in children with cancer. The aim of this study was analysis of infectious complications and results of conservative management in TIVADs. Three hundred and one catheters were implanted in 283 patients between February 1991 and January 2005. Infectious complications were analyzed retrospectively. Cumulative duration of implantation was 153,757 days. In 140 devices (46.5%), no complication was detected. Total rate of infection was 1.96/1000 catheter days. Types of infections were as follows: catheterrelated bloodstream infections: 190; catheter-related systemic infections: 74; pocket infections: 19, exit site infections: 14; and tunnel infections: 5. Staphylococcus epidermidis and non-albicans candida were the most common isolations. During follow-up, a total of 119 catheters had been removed. Most of them were due to infection (n=42). In conclusion, TIVADs are important in children with cancer who need prolonged intravenous access, so they should be used carefully and managed conservatively in case of complications.

Cardiac rhabdomyomas in childhood: six cases from a single institution.

Primary cardiac tumors are rare during childhood. The most frequently encountered tumors are rhabdomyomas. We reviewed the clinical characteristics, treatment results, and outcomes of six pediatric patients with primary cardiac rhabdomyomas. The mean age was 16.8 days. Only one patient was symptomatic. The tumors mostly originated from the left ventricle. The diagnosis was established by magnetic resonance imaging (MRI) plus echocardiography with or without histopathology. Total tumor resection was performed in two patients. After a median follow-up of 39 months, one patient had a stable tumor, two patients had marked tumor regression and one had complete tumor regression. Considering the fact that rhabdomyomas often show spontaneous regression, close follow-up may be sufficient in hemodynamically stable cases. Although rhabdomyomas do not cause any symptoms at the time of diagnosis, they may lead to sudden death; thus, further studies may be required for the decision of surgery and/or followup. The localization and infiltrative characteristics of the tumor are critical factors for decision-making in children with symptomatic rhabdomyoma even if surgery is indicated in such cases.

Tissue Doppler evaluation of systolic and diastolic cardiac functions in long-term survivors of Hodgkin lymphoma.

BACKGROUND: Monitoring for late adverse events is crucial in long-term management of childhood cancer survivors. A case-control study to evaluate long-term cardiovascular status of childhood Hodgkin lymphoma (HL) using tissue Doppler imaging (TDI) was performed. PATIENTS AND METHODS: Patients diagnosed with HL before age of 18 that completed therapy and were in remission and a control group of healthy children were evaluated by echocardiography and TDI. RESULTS: Total of 72 HL survivors were included in the study. Median age at diagnosis, remission time, and age at time of echocardiography were 7 (2-16), 9 (2-20), and 17.5 (7-27) years, respectively. TDI revealed decreased S' velocity, reflecting systolic dysfunction in HL survivors, at medial and lateral mitral annuli and at middle segment of interventricular septum (IVS; P < 0.01) for all. Moreover, TDI showed decreased peak E' velocity at medial mitral annulus [12.4 cm/s (5.5-16.3) vs. 13.3 cm/s (10.2-18.9), P = 0.03] and at middle segment of IVS [10 cm/s (5.3-16.3) vs. 11.6 cm/s (6.7-16.7), P < 0.01] and prolongation of isovolemic relaxation time at medial and lateral annuli of the mitral valve (P < 0.01) and at middle segment of IVS (P = 0.03) suggesting diastolic dysfunction in HL survivors. CONCLUSION: Cardiac dysfunction after childhood cancer therapy may develop after many years. Since systolic and diastolic dysfunction can be seen in these patients periodic echocardiographic screening of both systolic and diastolic function in the survivors of HL might be useful in the follow-up of these patients.

Health-related quality of life in pediatric cancer survivors: a multifactorial assessment including parental factors.

AIM: We aimed to evaluate the health-related quality of life (HRQOL) and the effect of associated factors such as cancer type, treatment strategies, sex, age, and parental factors like education and psychopathology in pediatric cancer survivors and make a comparison with healthy children. PATIENTS AND METHODS: "Pediatric Quality of Life Inventory (PedsQL) 4.0 TM, Generic Core Scale" for children and parents, and "Brief Symptom Inventory" for parents were used. Three hundred and two survivors without major mental or motor deficit and 272 healthy controls of 8 to 18 years of age were enrolled to study. RESULTS: Comparison of scores according to child self-report between survivor and control groups revealed lower points in physical and school subscale of survivor group (P<0.01 and P<0.001, respectively). Female survivors had reported significantly worse HRQOL in physical and emotional subscales of PedsQL than male survivors (P<0.001). Female survivors of ≥16 years of age had reported worse scores in school subscale than females of younger age groups and male survivors of same age group. Parents of control group reported better results in school subscales (P<0.001) and social functioning subscales (P<0.05) than parents of survivor group. Brief Symptom Inventory score had significant effect on child self-report and parent proxy-report of physical functioning (P<0.001), emotional functioning (P<0.001), social functioning (P<0.001), and school subscales (P<0.001) of PedsQL. Significantly better scores of physical functioning subscale in the survivors whose parents are university graduate than the survivors whose parents are primary school graduate were detected (P<0.001). The survivors with central nervous system tumors had reported lower scores in the social, emotional, physical, and school functioning subscales of PedsQL than patients with non-Hodgkin and Hodgkin lymphoma (P<0.001). Child self-report school subscale scores were lower in survivors treated with radiotherapy in combination or as sole therapy than survivors in whom radiotherapy was not given (P<0.001). CONCLUSIONS: Our study has provided evidence about less-studied determinants of HRQOL like parental factors such as psychopathology or educational level in childhood cancer survivors. Future research can build on this evidence to obtain additional factors other than well-known medical and treatment-related factors.

Malignant peripheral nerve sheath tumors in childhood: 13 cases from a single center.

PURPOSE: We aimed to review clinical characteristics, treatment results, and outcome for pediatric patients with malignant peripheral nerve sheath tumors (MPNSTs). METHODS: Files for 13 children diagnosed with MPNSTs and treated at our hospital between 1988 and 2009 were reviewed for clinical characteristics, treatment results, and outcome. RESULTS: The median patient age was 11 years (range, 0.16 to 18 y; female/male: 6/7). The most common symptoms were palpable mass (7 of 13) and pain (3 of 13). Four patients had neurofibromatosis type 1. Physical findings at diagnosis were palpable mass (10 of 13), scoliosis (2 of 13), paraplegia/cranial nerve palsy (2 of 13), and stigmas of neurofibromatosis type 1. The primary sites were head and neck (5 of 13), abdomen (3 of 13), chest wall (2 of 13), abdominal wall (2 of 13), and extremities (1 of 13). According to the Intergroup Rhabdomyosarcoma Study system, 5 cases were classified as Intergroup Rhabdomyosarcoma Study group I, 6 were classified as group III, and 2 were classified as group IV. Five-year overall and event-free survival rates were 34.6% (±13.8) and 18.8% (±11.9), respectively. Overall survival rates did not differ upon addition of chemotherapy and/or radiotherapy to the surgery. Five-year survival rates were 42.9% (±18.9) in patients with total resection and 37.5% (±28.6) in patients with partial resection (P=0.08). Overall survival rates did not differ according to stages (P=0.8). CONCLUSIONS: MPNSTs are rare in childhood and have an unfavorable prognosis. Whereas chemotherapy and/or radiotherapy had no promising effect on overall survival rates, complete resection seems to be the most effective treatment for MPNSTs. Further multicenter studies on the role of chemotherapy and/or radiotherapy for MPNSTs are warranted.

Thymomas in childhood: 11 cases from a single institution.

AIM: Thymomas are rare in children. Our aim was to review clinical and pathologic characteristics and outcome in children with thymomas. PATIENTS AND METHODS: Between 1979 and 2011, 11 children with thymomas were diagnosed. Hospital files were reviewed for presenting complaints, clinical, radiologic, and other laboratory data, surgical practices, chemotherapy and radiotherapy outcomes. RESULTS: Median age was 8 years (range, 1 to 13 y). Male to female ratio was 9/2. Most common initial complaints were dyspnea, cough, chest pain, and fever. Median time from onset of symptoms was 1 month (range, 0.23 to 3 mo). Associated conditions including hyper-IgE syndrome, hypogammaglobulinemia, and systemic lupus erythematosus plus idiopathic thrombocytopenic purpura were present in 3 patients. Chest x-rays and/or thoracic computed tomographies displayed thymic hyperplasia and/or masses in anterior mediastinum accompanied by pleural (n = 2) and pericardial effusions (n = 1), pulmonary metastases (n = 1), and cervical lymph node metastasis (n = 1). Compression or invasion of trachea or vessels was documented in 5 cases. Seven cases underwent initial tumor resection; others experienced open or trucut biopsies. Histopathologically, 5 cases had invasive and 6 had benign thymomas. Benign thymomas did not receive any postoperative treatment; all cases are disease free at a median follow-up of 211 months. Three of 5 cases with invasive thymomas underwent surgery, 4/5 received chemotherapy and external radiotherapy (3600 to 4500 cGy). Two invasive thymomas died of disease. Three cases with invasive thymomas are disease free at a median follow-up of 209 months. CONCLUSIONS: Benign thymomas have excellent prognosis. For invasive thymomas with or without metastasis, radiotherapy, and chemotherapy offers survival advantage. Complete surgical resection may increase chances for cure.

Temozolomide in relapsed pediatric brain tumors: 14 cases from a single center.

AIM: Temozolomide is an active drug against gliomas in adults. It also has some promising effects in pediatric patients with brain tumors. We have conducted a retrospective study to investigate the effectiveness of temozolomide in patients with relapsed brain tumors. PATIENTS AND METHODS: The files of 14 children treated at our hospital between 2005 and 2010 with the diagnoses of relapsed brain tumors were reviewed for pathological characteristics, treatment results, and outcomes. RESULTS: The median age at relapse was 8 years (range, 1.08-23; F/M, 5/9). Diagnoses included medulloblastoma (n = 5), atypical teratoid rhabdoid tumor (n = 2), ependymoma (n = 2), glioneuronal tumor (n = 1), malignant neoplasm (n = 1), pontine glioma (n = 1), astrocytoma grade III (n = 1), and glioblastoma multiforme (n = 1). All patients except the one with pontine glioma had undergone surgical resection, and all had prior adjuvant chemotherapy. Twelve out of 14 patients had received radiotherapy. The median number of temozolomide courses was 5.0 (range, 1-24). Objective response rate in our patients was 35.7% (three complete responses, one partial response, and one minor response). Stable disease achieved in 14.3% of patients and 50% had progressive disease. Median survival time was 8 months (range, 1-55). At the end of the study, three patients were alive. Hematological toxicity was seen in 30.8% of all courses. CONCLUSIONS: Relapsed brain tumors in childhood have an unfavorable prognosis. These data suggest that temozolomide might be an active agent against recurrent medulloblastoma. Although overall objective response rate was low, further multicentric studies with temozolomide may be warranted in children with recurrent brain tumors.

Long-term survival results of pediatric rhabdomyosarcoma patients: a single-center experience from Turkey.

The characteristics and clinical outcomes of 409 children with rhabdomyosarcoma, treated in a single center between 1972 and 2003, were evaluated to identify those characteristics that may have improved the outcome. Retrospective analysis was performed on 409 children for variables such as age, sex, primary tumor site, TNM (Tumor, Node, Metastasis) stage, Intergroup Rhabdomyosarcoma Studies (IRS) clinical group, histological subtypes, treatment. The mean age was 5.4 years and the male/female ratio was 1.6/1.0. Most of the patients were at stage III and the most common site of metastases was the lung. The median time of follow-up was 114 months. The 10-year event-free survival and overall survival rates were 27% and 33%, respectively. All parameters apart from sex and histological subtypes were found to be correlated with clinical outcome. Orbital and genitourinary system tumors (bladder-prostate tumors excluded), patients >1 year of age, TNM stage I and II tumors, IRS clinical group I and II tumors, grossly resectable tumors, and treatment with chemotherapy protocols containing anthracyclines correlated with better prognoses. In multivariate analyses, tumor invasion to surrounding tissue, regional lymph node involvement, and debulking surgery were found to be negatively correlated with prognosis. In children with rhabdomyosarcoma, survival rates can be improved owing to factors such as advancement in diagnostic and therapeutic techniques, improved supportive care, and a multidisciplinary approach.

The treatment of retinoblastoma with four-drug regimen including cisplatin, etoposide, vincristine, and cyclophosphamide.

Over an 11-year period, 59 patients (83 eyes) were treated with four-drug chemotherapy (cisplatin, etoposide, cyclophosphamide, and vincristine) at Hacettepe University, Departments of Ophthalmology and Pediatric Oncology. We evaluated the clinical features, treatment modalities, and outcome of these patients with a median follow-up of 55 months (range 9-130 months). Enucleation was performed as a first-line treatment for 30 eyes due to iris neovascularization and neovascular glaucoma, tumor in the anterior chamber regardless of the tumor stage, and for the patients with the Reese-Ellsworth (RE) group Vb. Chemotherapy was given regardless of tumor stages according to the RE groups in all 59 patients (83 eyes). Fifty-three eyes were treated with chemoreduction (CRD) and focal treatment. The rates of globe preservation were 87% for bilateral tumors and 35% for unilateral tumors in the CRD group. The 5-year overall (OS) and enucleation-free survival (EnFS) was 86.9% and 40%, respectively, for the whole group. At 3rd year, ocular survival rate for the eyes with vitreal or subretinal seeding was 58% and without seeding was 66% (P = .78). Seeding or subretinal collection may not indicate poor prognosis under intensive chemotherapy. The intensive four-drug chemotherapy protocol might have satisfactory results in the retinoblastoma (RBL) patients.

Mediastinal germ cell tumors in childhood.

BACKGROUND: Mediastinal germ cell tumors (GCTs) are rare and usually located in anterior mediastinum. We aimed to review clinical and pathological characteristics of these tumors. PROCEDURE: Between 1973 and 2011, 24 children with mediastinal GCTs were diagnosed. Hospital files were reviewed for presenting complaints, clinical, radiological and other laboratory data, surgical practices, treatments, and outcomes. RESULTS: Median age was 4.5 years (0.2-16) (male/female: 10/14). Most common initial complaints were dyspnea, cough, anorexia/fatigue, fever, and chest pain. Primary tumors were located in anterior mediastinum (n = 22), posterior mediastinum (n = 1), and sternum (n = 1). Thirteen of 24 cases had mature teratomas (54.2%); four (16.7%) endodermal sinus tumor (EST); four (16.7%) immature teratomas; and one (4.2%) each of embryonal carcinoma, teratocarcinoma, and malignant teratoma. Mature teratomas underwent only surgical resection and were under follow-up without disease. Four cases with ESTs received chemotherapy and radiotherapy (n = 3), three underwent surgical resections: three died, one was followed for 284 months in remission. All but one immature teratomas were treated with surgery and all were under follow-up without disease. Two patients with embryonal carcinoma and malignant teratoma didn't undergo surgery; both received chemotherapy and radiotherapy but died with disease. The patient with teratocarcinoma was treated with surgery and chemotherapy but died with disease. CONCLUSIONS: No adjuvant therapy is needed for mature teratomas. Immature teratomas must be under close follow-up for recurrences. Prognosis for mediastinal malignant GCTs was poor. These cases need intensive chemotherapies and effective local control measures as surgery -/+ radiotherapy to ensure long-term survival.

Posterior fossa syndrome after posterior fossa surgery in children with brain tumors.

BACKGROUND: Posterior fossa syndrome (PFS) is defined as the temporary and complete loss of speech after posterior fossa surgery. The goal of this study was to identify incidence and risk factors for PFS and to determine accompanying neurobehavioral and psychologic problems. PROCEDURE: Between May 2007 and April 2009, children with brain tumors having posterior fossa surgery were evaluated neurologically and psychologically in preoperative and postoperative period. RESULTS: PFS developed in 9 patients among 36 (25%) included in the study. Mutism continued for 120 days in one patient. Histopathological diagnosis (P = 0.05), location of the tumor (P = 0.05) and socioeconomic level of the family (P = 0.06) gave the significant results in relation with the PFS by univariate analyses. In multivariate analysis the risk of developing PFS was found 7.2 times higher in patients with medulloblastoma, 6.7 times higher in tumors located at the midline, 5.7 times higher in families with low socioecnomic level. Intelligence quotients of the patients in PFS and other group (P = 0.85) with Wechsler Intelligence Scale for Children and the results of the Denver II Developmental Screening Test were not significant statistically (P = 0.5). CONCLUSION: The diagnosis of medulloblastoma, midline location of the tumor and low socioeconomic level of the families are important risk factors for the development of PFS. These findings support the hypothesis that temporary ischemia and edema due to retracted and manipulated dentate nuclei and superior cerebellar pedincles may be the cause of mutism.

WAGR syndrome with tetralogy of Fallot and hydrocephalus.

Wilms tumor, aniridia, genitourinary abnormalities, and mental retardation (WAGR) syndrome occurs sporadically due to deletion of chromosome 11p13. A variety of other abnormalities involving different systems have been reported in patients with WAGR syndrome. We report on a patient with WAGR syndrome with accompanying tetralogy of Fallot and hydrocephalus.

Spinal low-grade neoplasm with leptomeningeal dissemination mimicking tuberculous meningitis in a child.

Spinal seeding of primary malignant intracranial tumors via CSF is common. However, this is rare in low-grade glial tumors. Cranial leptomeningeal metastasis of primary spinal cord low-grade gliomas at diagnosis or relapse is extremely rare. Leptomeningeal metastasis of spinal cord low-grade tumors may mimic tuberculous meningitis in children. A patient with primary spinal cord low-grade neoplasm mimicked tuberculous meningitis is presented. The patient successfully treated with chemoradiotherapy. At the end of 19-month follow-up, diffuse leptomeningeal infiltration and a dural mass compatible with relapse developed. Chemoradiotherapy was started.
