Estimate the annual incidence of medulloblastoma (MB) in the U.S. What is its frequency relative to other CNS tumors in children? ~500 cases/yr of MB in the U.S. It is the 2nd most common pediatric CNS tumor (20% of cases; #1 is low-grade glioma at 35%–50%).

This video describes how to identify medulloblastoma based on its classical imaging findings.

2 ⇓– 4 These subgroups have shown different clinical behaviors and may benefit from subgroup-specific treatments. Drawing of an axial section through the head shows a medulloblastoma in a typical location within the midline of the posterior fossa. On imaging studies, medulloblastoma commonly appears heterogeneous, due to areas of hemorrhage, cyst formation, and occasional areas of calcification, as depicted here. Estimate the annual incidence of medulloblastoma (MB) in the U.S. What is its frequency relative to other CNS tumors in children? ~500 cases/yr of MB in the U.S. It is the 2nd most common pediatric CNS tumor (20% of cases; #1 is low-grade glioma at 35%–50%). Medulloblastoma is the most common malignant brain tumor in pediatric patients and is a significant cause of cancer morbidity in children [ 1 ]. Composed of densely packed, small round cells, these tumors have relatively high density on CT studies and show reduced diffusion on MRI in comparison with other posterior fossa tumors [ 2 – 6 ].

Estimate the annual incidence of medulloblastoma (MB) in the U.S. What is its frequency relative to other CNS tumors in children? ~500 cases/yr of MB in the U.S. It is the 2nd most common pediatric CNS tumor (20% of cases; #1 is low-grade glioma at 35%–50%). Medulloblastoma is the most common malignant brain tumor in pediatric patients and is a significant cause of cancer morbidity in children [ 1 ]. Composed of densely packed, small round cells, these tumors have relatively high density on CT studies and show reduced diffusion on MRI in comparison with other posterior fossa tumors [ 2 – 6 ]. Background: Imaging diagnosis of medulloblastoma recurrence relies heavily on identifying new contrast-enhancing lesions on surveillance imaging, with diffusion-weighted imaging (DWI) being used primarily for detection of complications. We propose that DWI is more sensitive in detecting distal and leptomeningeal recurrent medulloblastoma than T1-weighted postgadolinium imaging. Medulloblastoma is the most common malignant pediatric brain tumor, accounting for 40% of childhood tumors in the posterior fossa.

Metastatic spread of medulloblastoma along the neuraxis by leptomeningeal seeding through the cerebrospinal fluid pathways is well known. The occurrence of extracranial metastases outside the neuraxis has been well established, but the occurrence of intramedullary spinal cord metastases not related to surface seeding is rare.

Adult Onset Medulloblastoma Cerebelli with Leptomeningeal Dissemination and Coincidental Primary Hyperparathyroidism Australasian Radiology, Vol. 33, No. 1 Computed tomography in management of medulloblastomas Treatment for medulloblastoma is likely to include a combination of surgery, radiotherapy and chemotherapy. The first course of treatment is usually neurosurgery to remove the tumour.

Recurrent Medulloblastoma: Frequency of Tumor Enhancement on Gd-DTPA MR Imaging 583 Thirty-two children with medulloblastoma were evaluated postoperatively with con ventional and gadolinium-enhanced MR imaging. Eleven patients had abnormal cranial MR studies; nine of these had recurrent tumor. In six patients recurrent tumor enhanced
