Medulloblastoma - sonic hedgehog (SHH) subgroup tumors are malignant tumors of the central nervous system. They are the second most common medulloblastoma subgroup (after group 4) and are approximately as common as group 3. They are found most commonly in adults and infants, but infrequently in children.

Medulloblastoma. Medulloblastoma is defined by the WHO as “an embryonal neuroepithelial tumor arising in the cerebellum or dorsal brainstem, presenting mainly in childhood and consisting of densly packed small round undifferentiated cells with mild to moderate nuclear pleopmorphism and a high mitotic count.”

Medulloblastoma is the most common malignant pediatric brain tumor, accounting for 40% of childhood tumors in the posterior fossa. 1 Genomic characterization of medulloblastoma has recently demonstrated that medulloblastomas can be subdivided into 4 distinct molecular subgroups: wingless (WNT), sonic hedgehog (SHH), group 3, and group 4. 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?

1 Division of Pediatric Radiology and Pediatric Neuroradiology, Russell H. Morgan Department of Radiology and Radiological Science, Johns Hopkins University School of Medicine, Baltimore, MD. 2 Department of Pathology, St. Jude Children's Research Hospital, Memphis, TN. Medulloblastoma is the most common malignant brain tumour of childhood and represents 15% to 20% of all brain tumours and 30% to 40% of all posterior fossa tumours in this age group, with an incidence of about 6 cases per million population per year in the US. 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.
