This article presents a summary of advanced MR imaging techniques and their use in the evaluation of patients with brain tumors. It reviews diffusion-weighted imaging, diffusion-tensor imaging, T2* susceptibility–sensitive imaging,…
This article reviews the most frequent extra-axial tumors of the central nervous system, from the most common meningioma to some uncommon conditions, like Rosai-Dorfman disease, focusing on imaging techniques, pearls,…
Some brain tumors results are interesting due to their rarity at presentation and overwhelming imaging characteristics, posing a diagnostic challenge in the eyes of any experienced neuroradiologist. This article focuses…
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…
