Abstract
Medulloblastoma (MB) cerebelli is a common brain tumor of the childhood. MB commonly spreads through cerebrospinal fluid; however, there are several reported cases of extracranial spread. The most common sites of extracranial metastasis are bones and bone marrow followed by peritoneum, liver, and lungs. Here, we report a case of pulmonary metastatic lesions of adult cerebellar MB that were discovered 1 year after the primary surgical treatment. We also tried to highlight similar reported cases in the literature.

Abstract
Medulloblastoma, an embryonal tumor located in the posterior fossa of the brain, originates from the neuro-epidermal layer of the cerebellum. It is the most prevalent malignant tumor in children, while it is rare in adults and predominantly affects males. Multimodal therapeutic interventions, such as surgery, radiotherapy, and chemotherapy, have substantially enhanced the prognosis of this condition. Extraneural metastases are infrequent. We present a case of medulloblastoma relapse with nodal metastasis in a 28-year-old adult.

Abstract
Introduction Lymph node metastasis (LNM) from primary tumors of the central nervous system (CNS) is an infrequent condition, and classically it was thought that CNS tumors could not spread via the lymphatic route. Recent discoveries about this route of dissemination make its knowledge necessary for surgeons and pathologists to avoid delays in diagnosis and unnecessary treatments. The aim of this paper is to review the literature and to discuss the relevant pathogenetic mechanism and the cytologic features along with recommendations for surgical treatment of these cervical LNM. Materials and Methods Using PRISMA guidelines, we conducted a systematic review of the literature published from 1944 to 2021, updating the comprehensive review published in 2010 by our group. Results Our review includes data of 143 articles obtaining 174 patients with LNM from a primary CNS tumor. The mean age of the patients was 31.9 years (range, 0.1–87) and there were 61 females (35.1%) and 103 males (59.2%), and in 10 cases (5.7%) the gender was not specified. The more frequent sites of distant metastasis were bones (23%), lungs (11.5%) and non-cervical lymph nodes (11%). Conclusion Cervical LNM from CNS tumors is infrequent. Pathologic diagnosis can be obtained by fine-needle aspiration cytology in most cases, giving surgeons the option to plan the appropriate surgical treatment. Given the poor prognosis of these cases, the most conservative possible cervical dissection is usually the treatment of choice.

Abstract
Medulloblastoma is the most common malignant solid tumor in childhood and the most common embryonal neuroepithelial tumor of the central nervous system. Several morphological variants are recognized: classic medulloblastoma, large cell/anaplastic medulloblastoma, desmoplastic/nodular medulloblastoma, and medulloblastoma with extensive nodularity. Recent advances in transcriptome and methylome profiling of these tumors led to a molecular classification that includes 4 major genetically defined groups. Accordingly, the 2016 revision of the World Health Organization's Classification of Tumors of the Central Nervous System recognizes the following medulloblastoma entities: Wingless (WNT)-activated, Sonic hedgehog (SHH)-activated, Group 3, and Group 4. This transcriptionally driven classification constitutes the basis of new risk stratification schemes applied to current therapeutic clinical trials. Because additional layers of molecular tumor heterogeneities are being progressively unveiled, several clinically relevant subgroups within the 4 major groups have already been identified. The purpose of this article is to review the recent basic science and clinical advances in the understanding of "medulloblastomas," and their diagnostic imaging correlates and the implications of those on current neuroimaging practice.

Abstract
Although most malignant lymphadenopathy in the neck represent lymphomas or metastases from head and neck primary tumors, occasionally, metastatic disease from remote, usually infraclavicular, sites presents as cervical lymphadenopathy with or without an obvious primary tumor. In general, these tumors metastasize to supraclavicular lymph nodes, but occasionally may present at an isolated higher neck level. A search for the primary tumor includes information gained by histology, immunohistochemistry, and evaluation of molecular markers that may be unique to the primary tumor site. In addition, 18F-fluoro-2-deoxyglocose positron emission tomography combined with CT (FDG-PET/CT) has greatly improved the ability to detect the location of an unknown primary tumor, particularly when in a remote location. Although cervical metastatic disease from a remote primary site is often incurable, there are situations in which meaningful survival can be achieved with appropriate local treatment. Management is quite complex and requires a truly multidisciplinary approach. © 2015 Wiley Periodicals, Inc. Head Neck 38: E2374-E2385, 2016.

Abstract
Medulloblastoma is the most common childhood malignant tumor of central nervous system, but it may also occur in adults. It presents high invasive growth with spreading of tumor cells into the leptomeningeal space along the neuroaxis early in the course of the disease. Extraneural metastases are rare but frequently lethal, occurring only in 1 to 5% of patients, and are related, in the most of cases, to the presence of ventriculoperitoneal shunt. Here we characterize the clinical profile of five cases of medulloblastoma with systemic spreading of tumor cells, also comparing them to cases already described in the literature.

Abstract
BACKGROUND Clinical outcome and prognostic factors were assessed in adult medulloblastoma patients, with emphasis on patterns of relapse. PATIENTS AND METHODS Records of 36 consecutive adult patients with medulloblastoma were reviewed. Patients were classified into 2 prognostic groups according to the extent of disease and quality of surgical excision based on the early postoperative magnetic resonance imaging (MRI) findings. Standard-risk (SR) patients (n = 11) received postoperative craniospinal radiation therapy (RT) only, 36 Gy, 1.8 Gy per daily fraction, with a 18 Gy boost to the posterior cerebral fossa (PCF). High-risk (HR) patients (n = 25) received additional adjuvant chemotherapy. RESULTS With a median follow-up of 46 months (range 5-155), 19 patients experienced tumour relapse. Sites of relapse(s) included tumour bed in 6 patients, resulting in a PCF control of 83.4%. Three-year overall survival (OS) and progression-free survival (PFS) were 67.3% and 57.4%, respectively. The comparison of the HR and SR populations demonstrated significant differences in OS (p = 0.005) and PFS (p = 0.001). Quality of surgical excision and extent of disease beyond the PCF were predictive factors for OS (p = 0.04, p = 0.001, respectively) and PFS (p = 0.004, and p = 0.02, respectively). CONCLUSION The quality of resection was a significant prognostic factor, suggesting that surgery should be as extensive as possible. Systematic postoperative MRI allowed accurate selection of SR patients for whom RT alone was enough to obtain high local control. Every effort should be made to avoid RT disruption. Increased delay led to worse outcome.

Abstract
OBJECT The question of whether to obtain routine or selective preoperative imaging of the neuraxis in pediatric patients with cerebellar neoplasms remains a controversial topic. Staging of the neuraxis is generally considered beneficial in patients with neoplasms associated with an elevated risk of leptomeningeal dissemination (LD). When these studies are obtained preoperatively, there is a decrease in the number of false-positive images related to debris in the immediate postoperative period. Additionally, knowledge of the extent of spread has the potential to affect the risk/benefit analysis of aggressive resection. Although the majority of pediatric neurosurgeons surveyed choose to obtain selective preoperative imaging of the neuraxis in cases of cerebellar neoplasms "with findings suggestive of high-grade pathology," an evidence-based protocol in the literature is lacking. The goal of this study was to assess radiological characteristics of tumors with an elevated risk of LD and identify a method to help guide preoperative imaging of the neuraxis. METHODS The authors first reviewed the literature to gain an appreciation of the risk of LD of pediatric cerebellar neoplasms based on underlying histopathology and/or grade. Available evidence indicates preoperative imaging of the neuraxis in patients with Grade I tumors to be of questionable utility. In contrast, evidence suggested that preoperative imaging of the neuraxis in patients with Grades II-IV neoplasms was clinically warranted. The authors then evaluated an extensive base of neuroradiological literature to identify possible MR imaging and/or CT findings with the potential to differentiate Grade I from higher-grade neoplasms in pediatric patients. They analyzed the preoperative radiological findings in 50 pediatric patients who had undergone craniotomy for resection of cerebellar neoplasms at Vanderbilt Children's Hospital since 2003 with reference to 7 chosen radiological criteria. Logistic regression models were fit using radiological features to determine the best predictors of Grades II-IV tumors. Receiver operating characteristic methods were used to identify diagnostic properties of the best predictors. RESULTS The relative T2 signal intensity (RT2SI), an indirect measure of the water content of the solid component of the tumor, was best able to identify neoplasms with an elevated risk of LD. An RT2SI value of 0.71 was selected by the authors as the best operating point on the curve. Of the 31 neoplasms retrospectively designated as hypointense T2-weighted lesions (RT2SI ≤ 0.71), 30 (97%) were Grade II or higher. All medulloblastomas, ependymomas, and high-grade (Grades III and IV) neoplasms were hypointense T2-weighted lesions. Of the 19 T2-weighted hyperintense neoplasms (RT2SI > 0.71), 16 (84%) were Grade I and 3 were Grade II. CONCLUSIONS Measurement of the RT2SI can help predict Grade II-IV tumors at an elevated risk of leptomeningeal spread and guide staging of the neuraxis. Pediatric patients with cerebellar neoplasms found to have an RT2SI of less than or equal to 0.71 are recommended for neuraxis imaging prior to surgery.

Abstract
In the realm of head and neck diseases, one particularly common clinical presentation is that of the patient with a cervical mass. In children, neck masses often prove to be developmental cysts; in adults, the recent onset of a neck mass can signal a metastasis from a head and neck squamous carcinoma. Less often, both adults and children may present with cervical masses caused by either non-Hodgkin's lymphoma or Hodgkin's disease. There are, of course, less frequently encountered differential diagnostic possibilities; one of the most uncommon of all is the possibility of metastasis from an intracranial tumor. Intracranial tumors rarely give rise to cervical node metastases. The present review examines the published experience with 128 tumors that gave rise to cervical node metastases in both adult and in pediatric patients. While it is presumed that the blood-brain barrier blocks the spread of most tumors beyond the intracranial locale, this is speculative. Although many of the cervical node metastases reported here arose after craniotomy (and, presumably, after breaching of the blood-brain barrier), some arose in the absence of any preceding surgical procedure. Cervical node metastases may arise from glial tumors (including glioblastoma multiforme, in both adult and pediatric patients) and non-glial tumors (such as medulloblastoma in pediatric patients). The history of a previous intracranial lesion is often the key to correct diagnosis, since, without prompting, neither the pathologist nor the radiologist is likely to think of a cervical node metastasis from a brain tumor when assessing a cervical mass of unknown etiology.

Abstract
Medulloblastoma is the most frequent childhood brain tumor (30%) but account only for less than 1% of adult brain tumor. The overall survival increased significantly during the last two decades with 80% of long survivors at five years whatever the stage. Most children who survive have significant neurocognitive sequelae. All children are included in national and international prospective studies which propose risk-adapted radiation therapy and chemotherapy after surgery. Quality control of radiotherapy leads to reduce significantly the risk of recurrence and has an impact on survival. Risks of late toxicity should be taken into account at the time of the treatment. Due to the rarety in adult population, no prospective studies and few data about late effects are available. Adult medulloblastoma is a therapeutic challenge and their therapeutic strategies are similar to pediatric protocols. In order to improve the understanding of adult disease and to homogenize the treatment, National Cancer Institute (INCa) stimulated the creation of web conference to discuss each case prospectively and to propose a protocol of treatment. A better comprehension of biological processes and abnormal cellular signalling pathways involved in medulloblastoma pathogenesis had led toward a new prognostic classification to adapt the therapeutic strategy and gives hope of new therapeutic tools.

Abstract
Medulloblastoma belongs to the group of highly malignant neuroepithelial tumours and is the commonest tumour in childhood (12–25 %)1, but is rare in adults (0.4–1%) of all primary brain tumours)1,2. Medulloblastomas usually arise in the posterior fossa and spread readily throughout the CSF, although 10–30% of patients develop extracentral nervous system metastases 2. We describe a 30-year-old woman presenting bone metastases from medulloblastoma located predominantly in the spine.
