Metastatic cancer to the central nervous system is primarily deposited by hematogenous spread in various anatomically distinct regions: calvarial, pachymeningeal, leptomeningeal, and brain parenchyma. A patient’s overall clinical status and…
The imaging of treated gliomas is complicated by a variety of treatment related effects, which can falsely simulate disease improvement or progression. Distinguishing between disease progression and treatment effects is…
Glioma is considered the most common type of primary central nervous system (CNS) tumor. Imaging is crucial for diagnosis, characterization, grading, and therapeutic planning of CNS gliomas. Along with a…
There are 2 types of central nervous system lymphoma: primary and secondary. Both have variable imaging features making them diagnostic challenges. Furthermore, a patient’s immune status significantly alters the imaging…
In adults, the most common expansile “mass” lesion in the posterior fossa is a subacute stroke, whereas the most common neoplastic lesion in the posterior fossa is cerebellar metastasis (intra-axial)…
Lara A. Brandão, MD, Editor This issue of Neuroimaging Clinics focuses on adult brain tumors. The most common posterior fossa tumors—metastasis and hemangioblastomas, among many differentials—are discussed in the first…
Primary central nervous system lymphomas are aggressive, high-cell-density tumors. There is recent increase in their incidence in immunocompetent patients. Knowledge of imaging findings on computed tomography and conventional MR imaging…
Suresh K. Mukherji, MD, MBA, FACR, Consulting Editor Once again, it is my distinct pleasure to thank Lara Brandão for guest editing this issue of Neuroimaging Clinics . In this…
Advanced MR imaging techniques, such as spectroscopy, perfusion, diffusion, and functional imaging, have improved the diagnosis of brain tumors in children and also play an important role in defining surgical…
Extraparenchymal lesions of childhood include neoplastic and nonneoplastic entities. Lesions affecting children are different from the most common entities affecting adults. Although there are imaging features that are highly suggestive…
