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. If you’re looking for an exciting career, then you should consider being a radiologic technologist. Working in the healthcare industry is one of the most rewarding positions, and many people choose to change careers later in life.

AJNR Am J Neuroradiol . 2017 Oct;38(10):1892-1898. doi: 10.3174/ajnr.A5313. 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.” In detail, patients were retrospectively identified via a full text query within the local radiology information system using the term “medulloblastoma.” The resulting 1,795 reports were primarily filtered for presurgical MRI scans.

Clinical imaging standards with minimum mandatory sequence acquisition that optimizes detection of leptomeningeal metastases are defined. Our findings support that DWI is more sensitive than contrast enhancement for detection of medulloblastoma recurrence, particularly in cases of leptomeningeal nonenhancing disease and distal nonenhancing focal disease. As such, recurrent medulloblastoma can present as a reduced diffusion lesion in a patient with normal postgadolinium contrast MRI. Myelography revealed unsuspected spinal cord metastases in an additional patient with recurrent medulloblastoma in the posterior fossa.

Therefore, it is difficult to differentiate them through visual observation in clinical diagnosis. Medulloblastoma is a heterogeneous disease comprising four molecular subgroups with distinct developmental origins, unique transcriptional profiles, diverse phenotypes, and varying clinical outcomes.

Group 3 tumors occur more commonly in males than females and are found in infants and children but almost never in adults. 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. However, if your child's tumour has caused a build-up of CSF, the surgeon may first need to perform an operation to reduce the pressure.

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. Assoc Prof Frank Gaillard ◉ ◈ et al. Medulloblastoma - wingless (WNT) subgroup tumors are the least common medulloblastoma subgroup and have by far the best prognosis.
